| X-ray view of a thousand-year-old cosmic tapestry Posted: 17 Apr 2013 01:50 PM PDT A long Chandra observation reveals the SN 1006 supernova remnant in exquisite detail. By overlapping 10 different pointings of Chandra's field-of-view, astronomers have stitched together a cosmic tapestry of the debris field that was created when a white dwarf star exploded, sending its material hurtling into space as seen from Earth over a millennium ago. In this new Chandra image, low, medium, and higher-energy X-rays are colored red, green, and blue respectively. |
| Astronomers discover massive star factory in early universe Posted: 17 Apr 2013 01:49 PM PDT A team of astronomers has discovered a dust-filled, massive galaxy churning out stars when the cosmos was a mere 880 million years old -- making it the earliest starburst galaxy ever observed. |
| SOFIA observations reveal a surprise in massive star formation Posted: 17 Apr 2013 10:25 AM PDT Researchers using the airborne Stratospheric Observatory for Infrared Astronomy (SOFIA) have captured the most detailed mid-infrared images yet of a massive star condensing within a dense cocoon of dust and gas. |
| Posted: 17 Apr 2013 10:20 AM PDT Like many of his colleagues at NASA's Jet Propulsion Laboratory, Pasadena, Calif., Shyam Bhaskaran is working a lot with asteroids these days. And also like many of his colleagues, the deep space navigator devotes a great deal of time to crafting, and contemplating, computer-generated 3-D models of these intriguing nomads of the solar system. But while many of his coworkers are calculating asteroids' past, present and future locations in the cosmos, zapping them with the world's most massive radar dishes, or considering how to rendezvous and perhaps even gently nudge an asteroid into lunar orbit, Bhaskaran thinks about how to collide with one. |
| Massive galaxy had intense burst of star formation when universe was only 6 percent of current age Posted: 17 Apr 2013 10:18 AM PDT Astronomers find the most prolific star factory yet seen, in a far-distant galaxy that reveals important information about the cosmic environment in the early history of the Universe. |
| ALMA telescope pinpoints early galaxies at record speed Posted: 17 Apr 2013 06:20 AM PDT Astronomers have used the new ALMA (Atacama Large Millimeter/submillimeter Array) telescope to pinpoint the locations of over 100 of the most fertile star-forming galaxies in the early Universe. |
