| Noble gas molecule discovered in space Posted: 12 Dec 2013 11:21 AM PST A molecule containing a noble gas has been discovered in space. The molecule, argon hydride, was seen in the Crab Nebula, the remains of a star that exploded 1,000 years ago. |
| Fast radio bursts might come from nearby stars Posted: 12 Dec 2013 09:34 AM PST First discovered in 2007, "fast radio bursts" continue to defy explanation. These cosmic chirps last for only a thousandth of a second. The characteristics of the radio pulses suggested that they came from galaxies billions of light-years away. However, new work points to a much closer origin -- flaring stars within our own galaxy. |
| Hubble Space Telescope sees evidence of water vapor venting off Jupiter moon Posted: 12 Dec 2013 08:33 AM PST NASA's Hubble Space Telescope has observed water vapor above the frigid south polar region of Jupiter's moon Europa, providing the first strong evidence of water plumes erupting off the moon's surface. Previous scientific findings from other sources already point to the existence of an ocean located under Europa's icy crust. Researchers are not yet fully certain whether the detected water vapor is generated by erupting water plumes on the surface, but they are confident this is the most likely explanation. |
| Hubble discovers water vapor venting from Jupiter’s moon Europa Posted: 12 Dec 2013 08:06 AM PST The Hubble Space Telescope has discovered water vapor erupting from the frigid surface of Jupiter's moon Europa, in one or more localized plumes near its south pole. Europa is already thought to harbor a liquid ocean beneath its icy crust, making the moon one of the main targets in the search for habitable worlds away from Earth. This new finding is the first observational evidence of water vapor being ejected off the moon's surface. |
