Massive galaxy cluster spawns more than 700 stars a year A newly discovered cluster of galaxies, more than 5 billion light years from Earth…is among the most massive clusters of galaxies in the universe, and produces X-rays at a rate faster than any other known cluster. It also creates new stars at an “unmatched” pace of more …

America regains the title of ‘fastest supercomputer on the planet’
Every six months, Earth’s biggest supercomputers have a giant race to see which can lay claim to being the world’s fastest high-performance computing cluster. In the latest Top 500 Supercomputer Sites list unveiled Monday morning, a newly assembled cluster built with IBM hardware at the Department of Energy’s Lawrence Livermore National Laboratory (LLNL) takes the top prize. …

The possible Galactic Core of our Universe (photo)
A globular cluster is a spherical collection of stars (like our Sun) that orbits a galactic core as a satellite. Globular clusters are very tightly bound by gravity, which gives them their spherical shapes and relatively high stellar densities toward their centers. Here is one of those globular clusters: Messier 9, seen here in a …
