First of missing primitive stars found Wednesday, March 3, 2010 @ 10:40PMAstronomers have discovered a relic from the early universe -- a star that may have been among the second generation of stars to form after the Big Bang. Located in the dwarf galaxy Sculptor some 290,000 light-years away, the star has a remarkably similar chemical make-up to the Milky Way's oldest stars. Its presence supports the theory that our galaxy underwent a "cannibal" phase, growing to ...

This Week's astro-ph Preprints: Jean Tate's Best Pick Thursday, February 25, 2010 @ 7:48PMIt goes by the super-catchy (not!) title "A Catalog of MIPSGAL Disk and Ring Sources". I chose it, over 213 competitors, because it's pure astronomy, and because it's something you don't need a PhD to be able to do, or even a BSc. Oh, and also because Don Mizuno and co-authors may have found two, [...]
For NASA no easy answer for next space destination Thursday, February 25, 2010 @ 2:49PMWhere to next? It is a simple question that NASA cannot answer so easily anymore.

Ripped to Shreds, Exoplanet Suffers Painful Death Thursday, February 25, 2010 @ 12:18PMWASP-12b, discovered in 2008, is a real outlier among the 400 or so exoplanets discovered to date. Not that it's particularly massive (it's a gas giant, not unlike Jupiter), nor that its homesun (host star) is particularly unusual (it's rather similar to our own Sun), but it orbits very close to its homesun, and is [...]
The Edge of Physics by Anil Ananthaswamy [Uncertain Principles] Thursday, February 25, 2010 @ 10:23AMOne of the weird-but-cool things about being C-list famous on the Internet is that some publishers now send me unsolicited review copies of forthcoming books about science. These aren't always the books I would really like to get free copies of, but, hey, free books. Among the books I've received in the last year or so is Anil Ananthaswamy's The Edge of Physics , which I got as an ARC several ...

What Do Students Know? Friday, February 12, 2010 @ 12:05PMBlack holes, frozen worlds, the "big bang," supernovae -- when it comes to telling strange and compelling stories, astronomy and space science educators can draw upon these and other denizens of a celestial zoo more outlandish than the animals in any earthly zoo. There is more to astronomy, however, than incredible objects and extreme theories. The underlying concepts on which astronomy is based ...
