One of the most perplexing discoveries in modern astronomy has been finding supermassive black holes, some weighing billions ...

Could the Universe have been born inside a black hole? This question, raised by a team of scientists, challenges the Big Bang ...

Black holes form through the collapse of a very massive star, but many mysteries remain about these puzzling stellar objects.

Using the XMM-Newton telescope, astronomers have witnessed high-speed "burps" erupting from a distant overfeeding ...

Black hole formation could be a little Big Bang in reverse, coupling the matter of a dying star with dark energy, the mysterious force driving the accelerating expansion of the universe.

Black holes can get big … really big. But just how big? It's possible they could top out at over a trillion times more massive than the sun. That's 10 times bigger than the largest known black ...

Some black holes form when a massive star collapses into itself. ... A black hole takes up zero space, but does have mass — originally, most of the mass that used to be a star.

The black hole is stealing material from a companion star, in a process that could show how black holes get a kick from supernova explosions that form them. U.S. World ...

Emerging from the collision: a snapshot from the simulation at γ = 10, showing the two colliding particles forming a black hole. (Courtesy: Phys. Rev. Lett.) New simulations of head-on collisions of ...

Space Weird black hole spewed star-forming jets 500 light years long. Black holes located in dwarf galaxies usually stop star formation, but now one has been seen seeding new stars through a huge ...
