| Shining a light on cool pools of gas in the galaxy Posted: 11 Jun 2013 11:48 AM PDT Newly formed stars shine brightly, practically crying out, "Hey, look at me!" But not everything in our Milky Way galaxy is easy to see. The bulk of material between the stars in the galaxy -- the cool hydrogen gas from which stars spring -- is nearly impossible to find. |
| Black hole naps amidst stellar chaos Posted: 11 Jun 2013 11:45 AM PDT Nearly a decade ago, NASA's Chandra X-ray Observatory caught signs of what appeared to be a black hole snacking on gas at the middle of the nearby Sculptor galaxy. Now, NASA's Nuclear Spectroscopic Telescope Array (NuSTAR), which sees higher-energy X-ray light, has taken a peek and found the black hole asleep. |
| Moon radiation findings may reduce health risks to astronauts Posted: 11 Jun 2013 11:43 AM PDT Space scientists report that data gathered by NASA's Lunar Reconnaissance Orbiter show lighter materials like plastics provide effective shielding against the radiation hazards faced by astronauts during extended space travel. The finding could help reduce health risks to humans on future missions into deep space. |
