A team of astronomers captured the moment when a wayward star was pulled into the mouth of a supermassive black hole.
A gamma ray burst close to Earth could be devastating.
If we survive for another 7.59 billion years, our planet will spiral into the outer layers of the dying sun and melt away forever.

Our understanding of heavy element production in supernovae, exploding stars way beyond our solar system, may need to change following some discoveries we have made looking not to the skies, but deep under…
Research of a supernova in our galaxy will increase the precision of which we can measure distances outside of our own galaxy…
