Learn About Black Holes

Narrator (April Hobart, CXC): If a star has three times or more the mass of the sun and collapses, it can form a black hole.
These bizarre objects are found across the universe within double-star systems and at the centers of galaxies where giant black holes grow.
X-ray telescopes like Chandra can see superheated matter that is swirling toward the event horizon of a black hole.
Chandra has revealed how black holes impact their environments, how they behave, and their role in helping shape the evolution of the cosmos.
