| New kind of cosmic flash may reveal birth of a black hole Posted: 03 May 2013 08:04 PM PDT According to an astrophysicist, a new kind of cosmic flash may reveal something never seen before: the birth of a black hole. |
| Hubble sees the remains of a star gone supernova Posted: 03 May 2013 12:15 PM PDT These delicate wisps of gas make up an object known as SNR B0519-69.0, or SNR 0519 for short. The thin, blood-red shells are actually the remnants from when an unstable progenitor star exploded violently as a supernova around 600 years ago. There are several types of supernovae, but for SNR 0519 the star that exploded is known to have been a white dwarf star -- a sun-like star in the final stages of its life. |
| Posted: 03 May 2013 06:49 AM PDT An undergraduate student has discovered that a process occurring in Saturn's magnetosphere is linked to the planet's seasons and changes with them, a finding that helps clarify the length of a Saturn day and could alter our understanding of the Earth's magnetosphere. |
