Astronomers have found an especially sneaky black hole – discovery sheds light on star death, black hole formation and gravitational waves

Astronomers have discovered the first dormant black hole outside of the Milky Way. These black holes are not absorbing matter from a nearby star, making them incredibly hard to find.
The good thing about space is that – even though it has lots of dangerous stuff floating in it, and lots of exploding stars – it’s so big and empty that it almost doesn’t matter. NASA/CXC/U.Texas

‘Supernova in a bottle’ will help create matter from light

In 1934, two physicists came up with a theory that described how to create matter from pure light. But they dismissed the idea of ever observing such a phenomenon in the laboratory because of the difficulties…
The explosion of a super-luminous supernovae can emit as much light as our sun will in 10 billion years. Rampant.Gaffer

Super-luminous supernovae: seriously worth the superlatives

Supernovae are the brilliant, explosive deaths of stars. For a short time, these explosions can outshine an entire galaxy containing billions of stars. A recently discovered rare class of supernovae, termed…
