The End of the Universe: Hot or Cold?
We've talked at great length about the beginning of the universe, everything we know, and what we don't yet know. But everything that has a beginning must have an end. How will the universe end? How can we tell? When will it happen?...

Doomed Neutron Stars Create Blast of Light and Gravitational Waves
Doomed neutron stars whirl toward their demise in this animation. Gravitational waves (pale arcs) bleed away orbital energy, causing the stars to move closer together and merge. As the stars collide, some of the debris blasts away in...

Black Holes Explained: What Is a Black Hole? How They Form?
A black hole is a celestial body or simply a place in space where the gravitational pull is so high that nothing, not even light can escape it. This is why it's completely black, and hence it's called a black hole. A black hole's...
