| Black holes abundant among the earliest stars Posted: 05 Jun 2013 04:07 PM PDT By comparing infrared and X-ray background signals across the same stretch of sky, astronomers have discovered evidence of a significant number of black holes that accompanied the first stars in the universe. |
| NASA's Spitzer sees Milky Way's blooming countryside Posted: 05 Jun 2013 11:00 AM PDT New views from NASA's Spitzer Space Telescope show blooming stars in our Milky Way galaxy's more barren territories, far from its crowded core. |
| Cat's Paw Nebula 'littered' with baby stars Posted: 05 Jun 2013 10:36 AM PDT Most skygazers recognize the Orion Nebula, one of the closest stellar nurseries to Earth. Although it makes for great views in backyard telescopes, the Orion Nebula is far from the most prolific star-forming region in our galaxy. That distinction may go to one of the more dramatic stellar nurseries like the Cat's Paw Nebula, otherwise known as NGC 6334, which is experiencing a "baby boom." |
| Young star suggests our sun was a feisty toddler Posted: 05 Jun 2013 10:36 AM PDT If you had a time machine that could take you anywhere in the past, what time would you choose? Most people would probably pick the era of the dinosaurs in hopes of spotting a T. rex. But many astronomers would choose the period, four and a half billion years ago, that our solar system formed. New work suggests that our sun was both active and "feisty" in its infancy, growing in fits and starts while burping out bursts of X-rays. |
