Simulation of Close Asteroid Fly-By 148

c0mpliant writes "NASA and the Jet Propulsion Laboratory have released a simulation of the path of an asteroid, named Apophis, that will come very close to Earth in 2029 — the closest predicted approach since humans have monitored for such heavenly bodies. The asteroid caused a bit of a scare when astronomers first announced that it would enter Earth's neighborhood some time in the future. However, since that announcement in 2004, more recent calculations have put the odds of collision at 1 in 250,000."

Big Dipper "Star" Actually a Sextuplet System 88

Theosis sends word that an astronomer at the University of Rochester and his colleagues have made the surprise discovery that Alcor, one of the brightest stars in the Big Dipper, is actually two stars; and it is apparently gravitationally bound to the four-star Mizar system, making the whole group a sextuplet. This would make the Mizar-Alcor sextuplet the second-nearest such system known. The discovery is especially surprising because Alcor is one of the most studied stars in the sky. The Mizar-Alcor system has been involved in many "firsts" in the history of astronomy: "Benedetto Castelli, Galileo's protege and collaborator, first observed with a telescope that Mizar was not a single star in 1617, and Galileo observed it a week after hearing about this from Castelli, and noted it in his notebooks... Those two stars, called Mizar A and Mizar B, together with Alcor, in 1857 became the first binary stars ever photographed through a telescope. In 1890, Mizar A was discovered to itself be a binary, being the first binary to be discovered using spectroscopy. In 1908, spectroscopy revealed that Mizar B was also a pair of stars, making the group the first-known quintuple star system."

Pirates as a Marketplace 214

John Riccitiello, the CEO of Electronic Arts, made some revealing comments in an interview with Kotaku about how the company's attitudes are shifting with regard to software piracy. Quoting: "Some of the people buying this DLC are not people who bought the game in a new shrink-wrapped box. That could be seen as a dark cloud, a mass of gamers who play a game without contributing a penny to EA. But around that cloud Riccitiello identified a silver lining: 'There's a sizable pirate market and a sizable second sale market and we want to try to generate revenue in that marketplace,' he said, pointing to DLC as a way to do it. The EA boss would prefer people bought their games, of course. 'I don't think anybody should pirate anything,' he said. 'I believe in the artistry of the people who build [the games industry.] I profoundly believe that. And when you steal from us, you steal from them. Having said that, there's a lot of people who do.' So encourage those pirates to pay for something, he figures. Riccitiello explained that EA's download services aren't perfect at distinguishing between used copies of games and pirated copies. As a result, he suggested, EA sells DLC to both communities of gamers. And that's how a pirate can turn into a paying customer."
