Something in outer space is breaking the law — the laws of physics, that is. Astronomers call these lawbreakers ultraluminous X-ray sources (ULXs), and they exude about 10 million times more energy ...

How did supermassive black holes end up at the center of every galaxy? A while back, it wasn’t that hard to explain: That’s where the highest concentration of matter is, and the black holes had ...

The Universe as we know it functions within certain limits - some of these limits are set in stone, like the speed of light, while others, just theorized, leave some ...

These objects are more than 100 times brighter than they should be. Observations by the agency’s NuSTAR X-ray telescope support a possible solution to this puzzle. Exotic cosmic objects known as ultra ...

Astronomers have spotted a black hole that dates back to just 1.5 billion years after the Big Bang — and the ancient monster is gobbling up matter at an astonishing rate. According to the scientists’ ...

In this illustration of an ultra-luminous X-ray source, two rivers of hot gas are pulled onto the surface of a neutron star. Strong magnetic fields, shown in green, may change the interaction of ...

A bizarre 'ultraluminous X-ray source' shines millions of times brighter than the sun, breaking a physical law called the Eddington limit, a new study finds. When you purchase through links on our ...
