Astronomers have puzzled for years over a strange pattern in the outer solar system. A surprising number of icy bodies far beyond Neptune resemble snowmen, made of two rounded lobes stuck together.

Supermassive black holes are capable of violently devouring entire stars, and warping the very fabric of spacetime with their near incomprehensible mass and gravitational influence. Their awesome ...

NASA scientists have reached a breakthrough in computer modeling that allows them to simulate what gravitational waves from merging black holes look like. The three-dimensional simulations, the ...

In collaboration with the US' Georgia Institute of Technology, researchers from Maynooth University in Ireland have unveiled a new computer simulation that mirrors early universe conditions, ...
