Comparing porch theft to multi-billion dollar white collar crime makes little sense. It's like comparing a whale to a tadpole—they're at opposite ends of the scale and they're not even the same species. Is that a fair comparison? The whale don't care. My primary concern is that we've willingly attached a national surveillance network to our front doors owned by a profit-making mega corporation working directly with law enforcement. And the kicker is they're using our tax dollars to motivate the entire operation.
Submission + - Simulation Showcases the Ferocious Power of a Solar Flare (astroengine.com)
astroengine writes: For the first time, scientists have created a computer model that can simulate the evolution of a solar flare, from thousands of miles below the photosphere to the eruption itself in the lower corona — the sun’s multimillion degree atmosphere. And the results are not only scientifically impressive, the visualization is gorgeous.
Submission + - Could This Bold New Technique Boost Gravitational-Wave Detection? (space.com)
astroengine writes: One of the most expensive, complex and problematic components in gravitational wave detectors like the Laser Interferometer Gravitational-wave Observatory (LIGO) — which made the first, historic detection of these ripples in space-time in September 2015 — is the 4-kilometer-long vacuum chambers that house all the interferometer optics. But what if this requirement for ground-based gravitational wave detectors isn't required? This suggestion has been made by a pair of physicists at the University of Maryland, Baltimore County (UMBC) who are developing a method that could allow extremely sensitive interferometers to operate in the "open air." Their work, published in the journal Physical Review Letters, uses the weird quantum properties of light to counteract interference from turbulence in the air to allow interferometer measurements to be made. Their method, which is a variation on the classic Young's double-slit experiment, has been demonstrated in a tabletop experiment — but gravitational wave scientists are skeptical that it could be scaled up to remove sophisticated vacuums from their detectors.
Submission + - NASA Science Chief: We're Not Racing SpaceX to Mars (seeker.com)
astroengine writes: According to NASA's new science chief Thomas Zurbuchen, the US space agency doesn't see SpaceX as a competitor in a race to Mars and that if any private company gets there before NASA, it will be cause for celebration and a huge science boon. "If Elon Musk brought the samples in the door right now I'd throw him a party out of my own money," Zurbuchen told reporters on Monday. He also said that polarizing topics, including science issues, need to be tackled with empathy for and patience with people who have opposing viewpoints. "Just because somebody doesn't agree with us the first time we open our mouths doesn't mean that they're stupid, or we're smart, or the other way around. I think it's really important to create, bring some empathy to the table," he told Seeker. "There's a lot of stuff that can be learned by just talking to people."
Submission + - Philae Found! Rosetta Spies Dead Comet Lander (seeker.com)
astroengine writes: With only a month before its mission ends, the European Space Agency's Rosetta mission swooped low over Comet 67P/Churyumov–Gerasimenko to see the stranded Philae lander jammed in a crack. After months of searching for the lander, which made its dramatic touchdown on Nov. 14, 2014, mission scientists had a good idea as to the region the robot was in, but this is the first photographic proof of the lander, on its side, stuck in the craggy location called Abydos. "This wonderful news means that we now have the missing 'ground-truth' information needed to put Philae's three days of science into proper context, now that we know where that ground actually is!" said Rosetta project scientist Matt Taylor in a statement.

Submission + - Astronomers to Announce "Earth-Like" Planet at Proxima Centauri (seeker.com)
astroengine writes: Scientists are preparing to unveil a new planet in our galactic neighborhood which is "believed to be Earth-like" and orbits its star at a distance that could favor life, German weekly Der Spiegel reported Friday. The exoplanet orbits a well-investigated star called Proxima Centauri, part of the Alpha Centauri star system, the magazine said, quoting anonymous sources. "The still nameless planet is believed to be Earth-like and orbits at a distance to Proxima Centauri that could allow it to have liquid water on its surface — an important requirement for the emergence of life," said the magazine. Though we need to be cautious of any report before an official announcement, this could be very exciting news as Proxima is, theoretically, within reach of an interstellar probe.
Submission + - "Miniature Pluto" Discovered in Outer Solar System (seeker.com)
astroengine writes: Astronomers have found another Pluto-like dwarf planet located about 20 times farther away from the sun than Neptune. The small planet, designed 2015 RR245, is estimated to be about 435 miles in diameter and flying in an elliptical, 700-year orbit around the sun. At closest approach, RR245 will be about 3.1 billion miles from the sun, a milestone it is expected to next reach in 2096. At its most distant point, the icy world is located about 7.5 billion miles away. It was found by a joint team of astronomers using the Canada-France-Hawaii Telescope (CFHT) on Maunakea, Hawaii, in images taken in September 2015 and analyzed in February. The discovery was announced on Monday in the Minor Planet Electronic Circular.
Submission + - Huge Jupiter-Like Storm Rages On Cool 'Failed Star' (discovery.com)
astroengine writes: Jupiter’s Big Red Spot is the largest example of a long-lived storm in the solar system, but now it has some pretty stiff competition in another star system. However, this “exo-storm” hasn’t been spied on another gas giant, it’s been spotted in the uppermost layers of a cool, small "failed star" or brown dwarf. Using 3 NASA space telescopes, new research published in The Astrophysical Journal has found that this spot isn't a starspot, but a bona fide storm that has more in common with Jupiter's famous cyclone. So is this REALLY a failed star? Or is is an "overachieving planet"?
Submission + - Confirmed: Japanese Spacecraft AKATSUKI Has New Eyes on Venus (discovery.com)
astroengine writes: The Japanese space agency JAXA has released a confirmation that their Venus mission Akatsuki did indeed enter orbit at Venus on Dec. 7 (JST) — releasing unprocessed images of the Venusian atmosphere as it entered orbit. The spacecraft is currently in a highly-elliptical 13-day, 14-hour orbit around the planet, coming within 400 kilometers (248 miles) at its closest point and reaching 440,000 kilometers (243,400 miles) away at its farthest. This mission has just become the most unlikely success story of 2015 after "missing" it's intended Venus orbit way back in 2010.
Submission + - Mauna Kea protests may end astronomy as we know it
StartsWithABang writes: If you want to explore the Universe, you need a telescope with good light gathering power, a high-quality camera to make the most out of each photon, and a superior observing location, complete with dark skies, clear nights, and still, high-altitude air. There are only a few places on Earth that have all of these qualities consistently, and perhaps the best one is atop Mauna Kea on Hawaii. Yet generations of wrongs have occurred to create the great telescope complex that's up there today, and astronomers continue to lease the land for far less than it's worth despite violating the original contract. That's astronomy as we know it so far, and perhaps the Mauna Kea protests signal a long awaited end to that.
Submission + - Mars Mission: How Hard? NASA Astronauts Weigh In (discovery.com)
astroengine writes: In an interesting interview with Discovery News, retired NASA astronauts Clay Anderson (Expedition 15/16) and Steve Swanson (Expedition 39/40) discussed their views on how the US space agency should select the first Mars-bound astronauts — a mission that is slated to commence in the late 2020's. While Swanson thinks that the current NASA astronaut selection process should suffice for a long-duration foray to the Red Planet, Anderson isn't so sure, saying, "(Mars) doesn’t require a jet fighter pilot. It doesn’t require a Ph.D. astronaut — although those people would be just fine, but I think that it’s going to take people that are very good generalists, that can do many things." As depicted in the upcoming Matt Damon movie, "The Martian," Mark Watney (Damon) is thrown into an unexpected, life-threatening situation, requiring him to use his general skill set to survive on the barren landscape until he's rescued. As the first manned missions to Mars will likely throw unforeseen challenges at the explorers, it will probably be a good idea to have a crew that are adept at thinking on the fly and skilled in many different areas rather than being a specialist in one.
Submission + - Rosetta's Comet is Actually 2 Comets Glued Together (discovery.com)
astroengine writes: Scientists have solved the mystery of why the comet being studied by Europe’s Rosetta spacecraft is shaped like a rubber duck — it started off as TWO separate comets, a new study shows. Ever since Rosetta sent back pictures of its twin-lobed target more than a year ago, scientists have debated whether the comet, known as 67P/Churyumov-Garasimenko, could be the result of two comets that merged together during the solar system’s early years. The other option is that the so-called “neck region” between 67P’s two lobes experienced some particularly active and still unexplained outgassing over the eons, eroding its more spherical shape into a body that resembles a rubber duck. “Our study rules out the possibility that the comet shape is the outcome of erosion,” planetary scientist Matteo Massironi, with the University of Padova in Italy, wrote in an email to Discovery News. Rather, the neck region is where two independent bodies collided, analysis of high-resolution images taken by the orbiting Rosetta spacecraft shows.
Submission + - Could Alien Life Spread 'Like a Virus' to the Stars? (discovery.com)
astroengine writes: As astronomical techniques become more advanced, a team of astrophysicists think they will be able to not only detect the signatures of alien life in exoplanetary atmospheres, but also track its relentless spread throughout the galaxy. The research, headed by Henry Lin of the Harvard-Smithsonian Center for Astrophysics (CfA), assumes that this feat may be possible in a generation or so and that the hypothesis of panspermia may act as the delivery system for alien biology to hop from one star system to another.
