Astronomers were looking through seven-year-old data when they chanced upon a very strange supernova that flashed and was gone in less than a month, when 3-4 months is typical. The unusually rapid ...

Just in time for July 4, astronomers say they have found a new type of stellar firecracker. Stars that die an explosive death generally fall into two categories: young, massive stars that collapse ...

Studies using X-ray and ultraviolet observations from NASA’s Swift satellite provide new insights into the elusive origins of an important class of exploding star called Type Ia supernovae. These ...

A bizarre exploding star that left its embers glowing invisibly in the distant sky seemed just like one of hundreds that flash into existence all the time - until one sharp-eyed astronomer noticed its ...

The night sky is filled with blips and flashes, a constantly changing sea of lights. Some of these changes are from Earth-bound happenings such as aircraft flying overhead, but some are from distant ...

The stars above seem fixed and constant, but the students in Dr. Peter Gonthier's Night Sky class have been experiencing a historic opportunity to see a dramatic change. The stars above seem fixed and ...

From the outlook of a planet that resides next to a quiet, relatively predictable star, the circumstances that lead to dramatic stellar explosions elsewhere in the universe can sound somewhat ...
