Not long ago, the center of the Milky Way exploded

A titanic, expanding beam of energy sprang from close to the supermassive black hole in the center of the Milky Way just 3.5 million years ago, sending a cone-shaped burst of radiation through both poles of the galaxy and out into deep space.

Mysterious supernova explosion

Supernovae happen all the time, but this one was different. "Cow," as astronomers are calling it, was a massively bright explosion 200 million light years away.

Astronomers Observe a Supernova Collapse in Real Time

With globe-spanning collaboration that enables to alert various telescopes to train their sights on the event, we are getting closer and closer to understanding how massive stars end their life and what leads up to the final explosion.

Mysterious cosmic explosion puzzles astronomers

A mysterious flash of X-rays has been discovered by NASA’s Chandra X-ray Observatory in the deepest X-ray image ever obtained. This source likely comes from some sort of destructive event, but may be of a variety that scientists have never seen before.

A young star is living out a growth spurt far from any other objects

In 2009 astronomers detected an unusual object, named CX330, as a source of X-rays as it was surveying the center of the Milky Way galaxy but they had not idea what it was. Today, astronomers have a better idea to what this strange object is.

Rare observation of cosmic explosion

Astronomers have discovered a new cosmic explosion: a gamma-ray burst and its associated supernova. Gamma-ray bursts (GRBs) are the most powerful blasts in the Universe, and are thought to be created in the deaths of the most massive stars.
