The Beautiful Universe: Chandra in HD NASA

Astronomers have shown that the famous black hole in Messier 87 is propelling particles faster than 99% of the speed of light using NASA's Chandra X-ray Observatory.

Astronomers and visualization specialists from NASA's Universe of Learning program have combined X-ray, visible, and infrared wavelengths to create a 3D representation of the dynamic Crab Nebula.

Two groups of galaxies located about 380 million light years from Earth are slamming into each other at about 4 million miles per hour.

Astronomers have uncovered a black hole that may have sparked the birth of stars over a phenomenal distance of more than a million light years and across multiple galaxies.

Scientists have found stars forming at a furious rate in the Phoenix galaxy cluster. The supermassive black hole in the center of galaxy clusters usually stifles star formation, but the one in Phoenix is not.

When two pairs of galaxy clusters collide, the result is not four separate objects, but one giant galaxy cluster.
