Astronomers Found Strange, Accelerating X-Ray Pulses Coming From a Black Hole. They Might Be a Sign of an Orbiting White DwarfThe dense stellar remnant would, if confirmed, be the closest known object to any black hole, according to preliminary ...
An international team of astronomers has reported the detection of a new exoplanet orbiting a bright late F-type star. The ...
When supermassive stars reach the end of their lives and explode in a supernova, the remnants form a super-dense object called a neutron star. Pulsars are neutron stars that spin rapidly ...
Scientists have detected emanating from the nucleus of a galaxy relatively close to our Milky Way flashes of X-rays gradually increasing in frequency that seem to be coming from a white dwarf - a ...
A strange black hole is making scientists scratch their heads.
The black hole, called Sagittarius A* (pronounced A-star), is an object about four million times the mass of our Sun and sits at the core of the Milky Way. Black holes are ultra-dense objects with ...
Its first moments were a period of pure energy with intense, possibly infinite, heat and density. As the universe expanded, it cooled and objects began to emerge, like snowflakes forming in cold air.
