| Diamond planets may be more common than astronomers thought Posted: 27 May 2014 07:05 PM PDT Carbon-rich planets may be more common than previously thought, according to new research. Some of these planets, all located far beyond Earth's solar system, could contain vast deposits of graphite or diamonds, and their apparent abundance prompts new questions about the implications of carbon-intense environments for climate, plate tectonics, and other geological processes, as well as for life. |
| Sunsets on Titan reveal the complexity of hazy exoplanets Posted: 27 May 2014 03:07 PM PDT Scientists working with data from NASA's Cassini mission have developed a new way to understand the atmospheres of exoplanets by using Saturn's smog-enshrouded moon Titan as a stand-in. The new technique shows the dramatic influence that hazy skies could have on our ability to learn about these alien worlds orbiting distant stars. |
| NASA-funded rocket to study birthplace of stars Posted: 27 May 2014 12:17 PM PDT In deep space, floating between the stars, lies an abundance of atoms -- carbon, oxygen, hydrogen -- that over millions of years will grow into new stars and new planets. NASA successfully launched the Colorado High-resolution Echelle Stellar Spectrograph, or CHESS, payload aboard a Black Brant IX suborbital sounding rocket on May 24, 2014, for a 15-minute flight to observe this star nursery more comprehensively and in better detail than has been done by a single instrument ever before. |
