| Astronomers find solar storms behave like supernovae Posted: 20 Feb 2014 07:29 AM PST Researchers have studied the behavior of the Sun's coronal mass ejections, explaining for the first time the details of how these huge eruptions behave as they fall back onto the Sun's surface. In the process, they have discovered that coronal mass ejections have a surprising twin in the depths of space: the tendrils of gas in the Crab Nebula, which lie 6500 light-years away and are millions of times larger. |
| Astronomers get first peek into core of supernova, using NuSTAR telescope Posted: 19 Feb 2014 10:33 AM PST Astronomers have peered for the first time into the heart of an exploding star in the final minutes of its existence. The feat by the high-energy X-ray satellite NuSTAR provides details of the physics of the core explosion inaccessible until now, says team member Steven Boggs of UC Berkeley. NuSTAR mapped radioactive titanium in the Cassiopeia A supernova remnant, which has expanded outward and become visible from Earth since the central star exploded in 1671. |
| Diamonds in the tail of the scorpion: Star cluster Messier 7 Posted: 19 Feb 2014 04:52 AM PST A new image shows the bright star cluster Messier 7. Easily spotted with the naked eye close to the tail of the constellation of Scorpius, it is one of the most prominent open clusters of stars in the sky, making it an important astronomical research target. |
