The giant, aging cables that support one of the world's largest single-dish radio telescopes are slowly unraveling in this U.S. territory, pushing an observatory renowned for its key role in astronomical discoveries to the brink of collapse. The Associated Press reports: The Arecibo Observatory, which is tethered above a sinkhole in Puerto Rico's lush mountain region, boasts a 1,000-foot-wide (305-meter-wide) dish featured in the Jodie Foster film "Contact" and the James Bond movie "GoldenEye." The dish and a dome suspended above it have been used to track asteroids headed toward Earth, conduct research that led to a Nobel Prize and helped scientists trying to determine if a planet is habitable. Last week, one of the telescope's main steel cables that was capable of sustaining 1.2 million pounds (544,000 kilograms) snapped under only 624,000 pounds (283,000 kilograms). That failure further mangled the reflector dish after an auxiliary cable broke in August, tearing a 100-foot hole and damaging the dome above it.

Officials said they were surprised because they had evaluated the structure in August and believed it could handle the shift in weight based on previous inspections. It's a blow for the telescope that more than 250 scientists around the world were using. The facility is also one of Puerto Rico's main tourist attractions, drawing some 90,000 visitors a year. Research has been suspended since August, including a project aiding scientists in their search for nearby galaxies. Some new cables are scheduled to arrive next month, but officials said funding for repairs has not been worked out with federal agencies. Scientists warn that time is running out. Only a handful of cables now support the 900-ton platform. The observatory estimates the damage at more than $12 million and is seeking money from the National Science Foundation, an independent federal agency that owns the observatory. The report notes that the observatory is considered crucial for the study of pulsars, which are the remains of stars that can be used to detect gravitational waves. It's also used to search for natural hydrogen, which can reveal how certain cosmic structures are formed.

The first detection of a fast radio burst inside the Milky Way leads scientists back to a magnetar, partially solving a long-standing mystery. CNET reports: Sifting through a trove of radio telescope data in 2007, Duncan Lorimer, an astrophysicist at West Virginia University, spotted something unusual. Data obtained six years earlier showed a brief, energetic burst, lasting no more than 5 milliseconds. Others had seen the blip and looked past it, but Lorimer and his team calculated that it was an entirely new phenomenon: a signal emanating from somewhere far outside the Milky Way. The team had no idea what had caused it but they published their results in Science. The mysterious signal became known as a "fast radio burst," or FRB. In the 13 years since Lorimer's discovery, dozens of FRBs have been discovered outside of the Milky Way -- some repeating and others ephemeral, single chirps. Astrophysicists have been able to pinpoint their home galaxies, but they've struggled to identify the cosmic culprit, putting forth all sorts of theories, from exotic physics to alien civilizations.

On Wednesday, a trio of studies in the journal Nature describes the source of the first FRB discovered within the Milky Way, revealing the mechanism behind at least some of the highly energetic radio blasts. The newly described burst, dubbed FRB 200428, was discovered and located after it pinged radio antennas in the US and Canada on April 28, 2020. A hurried hunt followed, with teams of researchers around the globe focused on studying the FRB across the electromagnetic spectrum. It was quickly determined that FRB 200428 is the most energetic radio pulse ever detected in our home galaxy.

In the suite of new papers, astrophysicists outline their detective work and breakthrough observations from a handful of ground- and space-based telescopes. Linking together concordant observations, researchers pin FRB 200428 on one of the most unusual wonders of the cosmos: a magnetar, the hypermagnetic remains of a dead supergiant star. It's the first time astrophysicists have been able to finger a culprit in the intergalactic whodunit -- but this is just the beginning. "There really is a lot more to be learned going forward," says Amanda Weltman, an astrophysicist at the University of Cape Town and author of a Nature news article accompanying the discovery. "This is just the first exciting step."

A new large-scale survey of the sky looked into the dark forest of the cosmos, examining over 10 million stars, but failed to turn up any evidence of alien technologies. CNET reports: The study, published in Publications of the Astronomical Society of Australia on Monday, details a search for extraterrestrial intelligence (SETI) using the Murchison Widefield Array (MWA), a collection of 4096 antennas planted in the red soil of Western Australia that detects radio signals from space. "They are little spider-like antennas that sit on the ground," explains Chenoa Tremblay, co-author on the study and astrophysicist with CSIRO, an Australian government scientific research organization.

Tremblay and co-author Stephen Tingay, from the International Centre for Radio Astronomy Research, used the MWA to listen out for "technosignatures," or evidence of alien technology, in a portion of the sky around the Vela constellation. Tremblay explains this region is scientifically interesting because a large number of stars have exploded and died, creating ideal conditions for new stars to form. The search for extraterrestrial life "piggy-backs" on other work studying this region to understand the life cycle of stars. [...] After listening to the Vela region for 17 hours, no unknown signals were detected. While the survey was able to capture over 10.3 million stellar sources and contained six known exoplanets (likely many more exist in the region), the team notes it was like trying to find something in an ocean, but only studying "a volume of water equivalent to a large backyard swimming pool." And there's another big caveat. "Looking for technosignatures is assuming that the civilization have technology similar to our own," says Tremblay.

According to a new report from Pew Research, U.S. adults who get their news largely from social media platforms tend to fllow the news less closely and end up less informed on several key subjects when compared to those who use other sources, like TV, radio, and news publications. TechCrunch reports: The firm first asked people how they most commonly get their news. About one-in-five (18%) said they mostly use social media to stay current. That's close the percentages of those who say they use local TV (16%) or cable TV (16%) news, but fewer than those who say they go directly to a news website or app (25%). Another 13% said they use network TV and only 3% said they read a newspaper. To be clear, any study that asks users to self-report how they do something isn't going to be as useful as those that collect hard data on what the consumers actually do. In other words, people who think they're getting most of their news from TV may be, in reality, undercounting the time they spent on social media â" or vice versa.

That said, among this group of "primarily" social media news consumers, only 8% said they were following the key news story of the 2020 U.S. election "every closely," compared with 37% of cable TV viewers who said the same, or the 33% of print users who also said this. The social media group, on this topic, was closer to the local TV group (11%). On the topic of the coronavirus outbreak, only around a quarter (23%) of the primarily social media news consumers said they were following news of COVID-19 "very closely." All other groups again reported a higher percentage, including those who primarily used cable TV (50%), national network TV (50%), news websites and apps (44%), and local TV (32%) for news.

Related to this finding, the survey respondents were also asked 29 different fact-based questions about news topics from recent days, including those on Trump's impeachment, the COVID-19 outbreak, and others. Those who scored the lowest on these topics were the consumers who said they primarily used social media to get their news. Across 9 questions related to foundational political knowledge, only 17% of primarily social media news consumers scored "high political knowledge," meaning they got 8 to 9 of the questions right. 27% scored "middle political knowledge" (6-7 right) and 57% scored "low political knowledge" (5 or fewer right.) The only group that did worse were those who primarily relied on local TV. 45% of who got their news from news primarily via websites and apps, meanwhile, had "high political knowledge," compared with 42% for radio, 41% for print, 35% for cable TV, and 29% for network TV. The social media group of news consumers was also more exposed to fringe conspiracies, like the idea that the pandemic was intentionally planned.

Julianne Pepitone from IEEE Spectrum writes about the uncertain future of ham radio. An anonymous reader shares an excerpt: Will the amateur airwaves fall silent? Since the dawn of radio, amateur operators -- hams -- have transmitted on tenaciously guarded slices of spectrum. Electronic engineering has benefited tremendously from their activity, from the level of the individual engineer to the entire field. But the rise of the Internet in the 1990s, with its ability to easily connect billions of people, captured the attention of many potential hams. Now, with time taking its toll on the ranks of operators, new technologies offer opportunities to revitalize amateur radio, even if in a form that previous generations might not recognize. The number of U.S. amateur licenses has held at an anemic 1 percent annual growth for the past few years, with about 7,000 new licensees added every year for a total of 755,430 in 2018. The U.S. Federal Communications Commission doesn't track demographic data of operators, but anecdotally, white men in their 60s and 70s make up much of the population. As these baby boomers age out, the fear is that there are too few young people to sustain the hobby.

This question of how to attract younger operators also reveals deep divides in the ham community about the future of amateur radio. Like any large population, ham enthusiasts are no monolith; their opinions and outlooks on the decades to come vary widely. And emerging digital technologies are exacerbating these divides: Some hams see them as the future of amateur radio, while others grouse that they are eviscerating some of the best things about it. No matter where they land on these battle lines, however, everyone understands one fact. The world is changing; the amount of spectrum is not. And it will be hard to argue that spectrum reserved for amateur use and experimentation should not be sold off to commercial users if hardly any amateurs are taking advantage of it. One of the key debates in ham radio is its main function in the future: Is it a social hobby? A utility to deliver data traffic? And who gets to decide? "Those questions have no definitive or immediate answers, but they cut to the core of the future of ham radio," writes Pepitone. "Loring Kutchins, president of the Amateur Radio Safety Foundation, Inc. (ARSFi) -- which funds and guides the 'global radio email' system Winlink -- says the divide between hobbyists and utilitarians seems to come down to age."

"Younger people who have come along tend to see amateur radio as a service, as it's defined by FCC rules, which outline the purpose of amateur radio -- especially as it relates to emergency operations," Kutchins (W3QA) told Spectrum last year. Kutchins, 68, expanded on the theme in a recent interview: "The people of my era will be gone -- the people who got into it when it was magic to tune into Radio Moscow. But Grandpa's ham radio set isn't that big a deal compared to today's technology. That doesn't have to be sad. That's normal."

"Ham radio is really a social hobby, or it has been a very social hobby -- the rag-chewing has historically been the big part of it," says Martin F. Jue (K5FLU), founder of radio accessories maker MFJ Enterprises, in Starkville, Miss. "Here in Mississippi, you get to 5 or 6 o' clock and you have a big network going on and on -- some of them are half-drunk chattin' with you. It's a social group, and they won't even talk to you unless you're in the group."

Tilley, an amateur radio operator living in Canada, found a "zombie" military satellite that was supposed to shut down in 1972. NPR reports: Recently, Tilley got interested in a communications satellite he thought might still be alive -- or at least among the living dead. LES-5, built by the Massachusetts Institute of Technology's Lincoln Laboratory, was launched in 1967. Tilley was inspired by another amateur who in 2016 had found LES-1, an earlier satellite built by the same lab. What was intriguing to him about LES-5 was that if it was still working, it might be the oldest functioning satellite still in geostationary orbit. By scouring the Internet, he found a paper describing the radio frequency that LES-5, an experimental military UHF communications satellite, should be operating on -- if it was still alive. So he decided to have a look.

"This required the building of an antenna, erecting a new structure to support it. Pre-amps, filters, stuff that takes time to gather and put all together," he says. "When you have a family and a busy business, you don't really have a lot of time for that," he says. But then came the COVID-19 pandemic. British Columbia, where Tilley lives, was on lockdown. Like many of us, suddenly Tilley had time on his hands. He used it to look for LES-5, and on March 24, he hit the ham radio equivalent of pay dirt. While Tilley thinks it may be possible to send commands to the satellite, the MIT lab that built LES-5 didn't comment on the matter when NPR inquired.

Sonos launched its first audio service Tuesday, called Sonos Radio. It promises free and exclusive music programming across a few dozen stations. From a report: Many of these stations will be supported by advertising -- a new business for Sonos, which the company is entering at a time when the ad business is feeling the pressure of an evolving economic downturn. However, for Sonos, the radio service also represents a new opportunity to lean more heavily into product partnerships like its existing relationship with Ikea, and expand to new product categories, including automotive. As such, it's an interesting example for a consumer electronics company using services not only to generate revenue but also as a way to expand its core business.

Satellite radio giant SiriusXM announced today it's made its 300-plus channel streaming service available for free in North America starting today through May 15.

People staying at home due to the coronavirus pandemic appear to be listening to more radio rather than music apps, figures suggest. The BBC reports: Global, which owns Capital FM and talk station LBC, said online radio listening had risen by 15%. The BBC said streaming of its radio stations had risen 18% since last week. Meanwhile, data from two US analytics companies suggested use of music-streaming apps such as Spotify had dipped by about 8%.

According to trusted music industry monitor BuzzAngle, US music streaming between 13-19 March fell by 8.8% compared with the previous week. Rolling Stone magazine, which uses a different data provider, Alpha Data, said streams were down 7.8%. But not all services are equally affected. Classical music site Primephonic said streaming had gone up by about 20% since isolation measures had been introduced in Europe. "There are likely to be multiple causes," said BBC News music reporter Mark Savage. "Fewer people are commuting to work or going to the gym and shops that use Spotify for their in-store music are closing their doors. People who stream music in the office also seem to be turning off and watching Netflix instead and there's a big rise in radio listening - suggesting we're seeking companionship alongside our music."

An anonymous reader quotes a report from IEEE Spectrum: A test by Penumbra Brands to measure how much radiofrequency energy an iPhone 11 Pro gives off found that the phone emits more than twice the amount allowable by the U.S. Federal Communications Commission. The FCC measures exposure to RF energy as the amount of wireless power a person absorbs for each kilogram of their body. The agency calls this the specific absorption rate, or SAR. For a cellphone, the FCC's threshold of safe exposure is 1.6 watts per kilogram. Penumbra's test found that an iPhone 11 Pro emitted 3.8 W/kg.

Ryan McCaughey, Penumbra's chief technology officer, said the test was a follow up to an investigation conducted by the Chicago Tribune last year. The Tribune tested several generations of Apple, Samsung, and Motorola phones, and found that many exceeded the FCC's limit. Penumbra used RF Exposure Labs, an independent, accredited SAR testing lab for the tests (The Tribune also used the San Diego-based lab for its investigation). Penumbra was conducting the test, which also included testing an iPhone 7, to study its Alara phone cases, which the company says are designed to reduce RF exposure in a person. It's worth noting that when the FCC conducted a follow-up investigation they did not find evidence that any of the phones exceed SAR limits. "That said, while the Tribune and Penumbra both used off-the-shelf phones, the FCC largely tested phones supplied by the manufacturers, including Apple," adds IEEE Spectrum.

Joel Moskowitz, a researcher at UC Berkeley, says that could be because there's a systematic problem with RF Exposure Lab's testing methods, or Apple rigged the software in the provided test phones to ensure they didn't put out enough power to exceed the SAR limit. Either way, both McCaughey and Moskowitz agree that the FCC's RF exposure testing is woefully out of date, as the limits reflect what the FCC deemed safe 25 years ago.

An anonymous reader quotes a report from TechCrunch: An amateur radio rig exposed to the internet and discovered by a security researcher was collecting real-time medical data and health information broadcast by hospitals and ambulances across U.K. towns and cities. The rig, operated out of a house in North London, was picking up radio waves from over the air and translating them into readable text. The hobbyist's computer display was filling up with messages about real-time medical emergencies from across the region. For some reason, the hobbyist had set up an internet-connected webcam pointed at the display. But because there was no password on the webcam, anyone who knew where to look could also see what was on the rig's computer display.

Daley Borda, a security researcher and bug bounty hunter, stumbled upon the exposed webcam. The live stream was grainy, and the quality of the images so poor that it was just possible to make out the text on the display. "You can see details of calls coming in -- their name, address, and injury," he told TechCrunch. TechCrunch verified his findings. Messages spilling across the screen appeared to direct nearby ambulances where to go following calls to the 999 emergency services. One message said a 98-year-old man had fallen at his home address. A few moments later, another message said a 49-year-old male was complaining of chest pains at a nearby residence. One after the other, messages were flooding in, describing accidents, incidents and medical emergencies, often including their home addresses. "The hobbyist was picking up and decoding pager communications from a nearby regional National Health Service trust," adds TechCrunch. These devices remain a fixture in UK hospitals and "allow anyone to send messages to one or many pagers at once by calling a dedicated phone number, often manned by an operator, which are then broadcast as radio waves over the pager network."

While the NHS still uses about 130,000 pagers, according to the UK government, it's not clear how many trusts are exposing medical information -- if at all.

An anonymous reader quotes a report from Fast Company: Motorola Solutions (not to be confused with Motorola Mobility, which makes the smartphones you know), the biggest global player in these LMR walkies, is releasing what appears to be the most advanced walkie-talkie ever. Called the APX Next, it's a chunky black brick with a thick antenna and a giant push-to-talk button on its side. Much like an iPhone, it also features a touchscreen on its front -- but don't be distracted by that. Its real innovation was born from 2,000 hours of interviews and testing with more than 50 emergency service agencies, including SWAT teams and detectives. It's a voice-recognition system that can operate in extremely loud environments, with artificial intelligence software that can look up 95 of the most common things a police officer or firefighter would call into dispatch -- like a driver's license, or license plate -- without any human operator on the other end of the line. But its ultimate promise is simply to free up the user's hands as much as possible, ensuring that someone is as safe and capable as possible during an emergency.

APX Next is a walkie-talkie and a cellphone combined. It has both the high-powered radio chip for land communications and a low-powered 4G/LTE chip for cell-tower data. These two chips can work at the same time, which is an engineering challenge, especially because the walkie-radio has 25 times the wattage of the 4G chip. The core buttons, including the large talk button, are all designed as you'd expect, to ensure they can be used without looking, and purely by muscle memory in stressful situations. Four separate microphones capture your voice, with programming designed specifically to cancel out exceptionally loud noises. But it isn't always listening for a wake word like the Echo or Google Home. You need to hit a button to cue the assistant. The company says it's using unnamed third parties to handle the natural language processing in the cloud. "What Motorola did was train the model specifically to handle things like ten-codes and even regionally specific dialects across the U.S," the report says.

"Once a question is sent to the cloud, the AI is able to scour a city or force's database for the same private information a dispatcher would be looking up." What's also neat is that the AI won't automatically read sensitive information out loud. Instead, the radio will beep when it has an answer, and the user can get to a private place, if they wish, before hitting a button to hear the results.

IEEE Spectrum describes how the U.S. Defense Advanced Research Projects Agency (DARPA) partnered with Pivot Technology Services to help them relocate their massive radio-frequency emulation testbed, called "Colosseum." The testbed was built for the agency's Spectrum Collaboration Challenge (SC2) -- a three-year competition to demonstrate the validity of using AI to work together in order to use wireless spectrum more efficiently than operating on pre-allocated bands. Slashdot reader Wave723 shares an excerpt from the report: Colosseum was originally built and housed at Johns Hopkins University Applied Physics Laboratory. That changed at the beginning of October, when the testbed was dismantled and later trucked to Los Angeles for the competition's finale, scheduled to begin at 3:30pm PDT today at MWC Los Angeles. [...] There may have been some molehills during the checks, but moving Colosseum definitely qualifies as a mountain. The testbed uses 3 Peta-Ops per second of computing power and 52 terabytes per second of data to emulate 65,000 channel operations between 256 wireless devices. It can draw up to 92 kilowatts of power and requires 200 gallons of water per minute to cycle through its cooling system to keep it from overheating.

Colosseum is housed within a space twice of the size of a cargo container -- in fact, its housing is literally built from two converted cargo containers put side by side. The halves arrived at the Los Angeles Convention Center during the set-up for MWC Los Angeles, and were hauled into the building and onto the convention floor by two 18-wheelers. We're going to move right past the crazy fact that DARPA and its hired logistics companies drove two semi-trucks into the Los Angeles Convention Center, because it gets better. To actually lower Colosseum's halves onto the ground, the next step involved something that both Tilghman and Gabel referred to as a "forklift ballet." As it turned out, the convention center didn't have a forklift strong enough to lift either half, so everyone improvised and used four smaller forklifts simultaneously by carefully arranging them around each half of Colosseum. It worked, but Gabel, in showing me a video of the forklift ballet, pointed out a moment where one of the forklift's rear wheels lifted off the ground as the machine and its operator grappled with Colosseum's weight...

Physicists at Stockholm University and the Max Planck Institute of Physics have proposed a novel design for an "axion radio" that employs cold plasmas (gases or liquids of charged particles) to "listen" for dark matter. Their paper has been published in the journal Physical Review Letters. Ars Technica reports: "Finding the axion is a bit like tuning a radio: you have to tune your antenna until you pick up the right frequency," said co-author Alexander Millar, a postdoc at Stockholm University. "Rather than music, experimentalists would be rewarded with 'hearing' the dark matter that the Earth is traveling through." [...] According to quantum mechanics, particles can exhibit wavelike behavior as well as particle characteristics. So an axion would behave more like a wave (or wave packet) than a particle, and the size of the wave packets is inversely proportional to their mass. That means these very light particles don't necessarily need to be tiny. The downside is that they interact even more weakly with regular matter than [weakly interacting massive particles], or WIMPS, so they cannot be produced in large colliders -- one current method for detecting WIMPs.

Physicists don't know what the axion's mass might be, so there's a broad parameter space in which to search, and no single instrument can cover all of it, according to co-author Matthew Lawson, also a postdoc at Stockholm University. That's why physicists have been developing all kinds of smaller experiments for detecting axions, from atomic clocks and resonating bars, to shining lasers at walls on the off-chance a bit of dark matter seeps through the other side. Yet most instruments to date are capable of detecting axions only within a very limited mass range. [...] Lawson et al. have come up with an innovative design for a tunable plasma-based haloscope. Their proposed instrument exploits the fact that axions inside a strong magnetic field will generate their own small electric field. This in turn drives oscillations in the plasma, amplifying the signal. [...] At the moment, Lawson et al.'s design is theoretical, but several experimental groups are actively working on building prototypes. "The fact that the experimental community has latched onto this idea so quickly is very exciting and promising for building a full-scale experiment," said Millar.

Japan's sole pager provider, Tokyo Telemessage Inc, will shut down radio signals for its services Tuesday, ending support for the device first introduced in the country half a century ago. Japan Today reports: In recent years, the device had been favored mainly by those working in hospitals, where cellphone use was once discouraged because of concerns over the effect of electromagnetic waves on medical devices and where cellphone reception can sometimes be poor. Beeper services in Japan began in 1968 with the predecessor of Nippon Telegraph and Telephone Corp. Users would call a specific number via a landline, causing the device to emit a beeping sound. But from the late 1980s onward, the popularity of pagers grew as they could be used to send messages combining numbers and text characters.

The number of pager users exceeded 10 million in 1996, with the device becoming one of the defining symbols of a subculture among female high school students along with "loose socks" and taking photos in puri-kura photo booths. However, beeper services declined with the introduction of mobile phones. The number of pager users further decreased as e-mailing, texting as well as taking and sending pictures by phone became standard.

An anonymous reader quotes a report from Motherboard: Meet AdBlock Radio, an adblocker for live radio streams and podcasts. Its creator, Alexandre Storelli, told Motherboard he hopes to help companies "develop alternative business models for radio and podcast lovers that do not want ads." "Ads exploit the weaknesses of many defenseless souls," Storelli told Motherboard. "Ads dishonestly tempt people, steal their time and promise them a higher social status. Blocking them will be a relieving experience for many."

Most audio ads exploit "auditory artifacts" to produce an ad that can't be ignored or tuned out because it feels louder than it actually is -- this has gotten so bad that there has actually been a "sonic arms race" where ads have been made increasingly louder over the years. "Adblock Radio detects audio ads with machine-learning and Shazam-like techniques," Storelli wrote about the project. He said he's been working on it for more than three years and that it uses techniques such as speech recognition, acoustic fingerprinting, and machine learning to detect known ad formats. It uses a crowdsourced database of ads and "acoustic fingerprinting," which converts audio features into a series of numbers that can be combed by an algorithm. Storelli has made Adblock Radio open-source and given detailed instructions on how to build on it, integrate it into user devices, and deploy it in a way that pressures radio stations (and podcasts) to self-regulate the quality of their ads.

Newer Guy writes: Entercom Communications, one of the USA's largest radio broadcasting companies, has been hit with a ransomware-like incident. It apparently came in from a computer in the programming department and has taken out the company's email system and servers. All their radio stations across the country have been affected. The ransomware people demanded half a million dollars to restore things; Entercom refused to pay.

WFMU's Free Music Archive -- a digital library of high-quality and legal downloads that users could listen to, remix, and share -- is shutting down due to funding shortages. The Verge reports: "The future is uncertain, has been my mantra lately," says Cheyenne Hohman, who's been the director of the Free Music Archive since 2014. The shutdown date was initially the 9th, but has since been pushed back to November 16th because the FMA is in early talks with four different organizations that are interested in taking the project over. "The site may stay up a little bit longer to ensure, at the very least, that our collections are backed up on archive.org and the Wayback Machine." Even so, it's not a perfect solution. "If it just goes into archive.org, it's going to be there in perpetuity, but it's not going to be changing at all," Hohman says. "It's not going to be the same thing, that sort of community and project that it was for ... almost 10 years."

Sirius XM has agreed to buy online-music service Pandora for $3.5 billion, as the satellite-radio company looks to add streaming services in the increasingly competitive fight for listeners. From a report: According to the announcement, the deal will create "the world's largest audio-entertainment company," with more than $7 billion in projected revenue in 2018 and more than 100 million monthly listeners, combining SiriusXM's 36 million subscribers and Pandora's 70 million-plus monthly active users. It also moves SiriusXM and its parent company, Liberty Media, aggressively into the streaming market. The transaction is expected to close in the first quarter of 2019 and is subject to approval by Pandora stockholders; expiration or termination of any applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act and certain competition laws of foreign jurisdictions; and other customary closing conditions. On a call with analysts, Jim Meyer, Sirius XM's chief executive, said that the acquisition would enable Sirius to try to keep listeners who did not want to pay for music by diverting them toward Pandora's free ads-based model.
