| NASA's asteroid sample return mission moves into development Posted: 16 May 2013 01:59 PM PDT NASA's first mission to sample an asteroid is moving ahead into development and testing in preparation for its launch in 2016. |
| Galaxy's 'burning ring of fire' is frenetic region of star formation Posted: 16 May 2013 01:53 PM PDT Johnny Cash may have preferred this galaxy's burning ring of fire to the one he sang about falling into in his popular song. The "starburst ring" seen at center of a new image in red and yellow hues is not the product of love, as in the song, but is instead a frenetic region of star formation. The galaxy, a spiral beauty called Messier 94, is located about 17 million light-years away. |
| Weather on the outer planets only goes so deep Posted: 16 May 2013 07:56 AM PDT What is the long-range weather forecast for the giant planets Uranus and Neptune? These planets are home to extreme winds blowing at speeds of over 1000 km/hour, hurricane-like storms as large around as Earth, immense weather systems that last for years and fast-flowing jet streams. Researchers set an upper limit for the thickness of jet streams on Uranus and Neptune. |
| Asteroid 1998 QE2 to sail past Earth is nine times larger than cruise ship Posted: 16 May 2013 06:53 AM PDT On May 31, 2013, asteroid 1998 QE2 will sail serenely past Earth, getting no closer than about 3.6 million miles (5.8 million kilometers), or about 15 times the distance between Earth and the moon. And while QE2 is not of much interest to those astronomers and scientists on the lookout for hazardous asteroids, it is of interest to those who dabble in radar astronomy and have a 230-foot (70-meter) -- or larger -- radar telescope at their disposal. |
