supernovae

The black hole is stealing material from a companion star, in a process that could show how black holes get a kick from supernova explosions that form them.

Betelgeuse a nearby red supergiant star which is up to 20 times more massive than our sun.

A typical gamma ray burst lasting seconds or minutes produces about the same energy as our sun does over the course of its entire multi-billion-year lifecycle.

The center of our galaxy is located around 26,500 light-years away from Earth.

The latest findings shed new light on supernova explosions and the late stages of stellar evolution.

You can help astrophysicists keep track of unidentified supernovas in the universe, and be recognized as a co-discoverer.

The strange events were identified by a project set up to investigate dark energy, an unexplained force that scientists think is accelerating the universe's expansion.

"When I first saw the Kepler data...my jaw dropped. I said, 'Oh wow!'"

When massive stars come to the end of their life cycles, they self-destruct in a cataclysmic final explosion.

Some long-lost electrons are lost no more.
