NGC 6278 and PGC 039620 are two galaxies from a sample of 1,600 that were searched for the presence of supermassive black holes. These images represent the results of a study that suggests that smaller galaxies do not contain supermassive black holes nearly as often as larger galaxies do. The study analyzed over 1,600 galaxies [...]

X-ray: NASA/CXC/Univ. of Chicago/H. McCall Galaxy clusters are the most massive objects in the universe held together by gravity, containing up to several thousand individual galaxies and huge reservoirs of superheated, X-ray-emitting gas. The mass of this hot gas is typically about five times higher than the total mass of all the galaxies in galaxy [...]
Nicolas Escurat A flash of lightning, and then—something else. High above a storm, a crimson figure blinks in and out of existence. If you see it, you are a lucky witness of a sprite, one of the least-understood electrical phenomena in Earth’s upper atmosphere. Sprites occur at some 50 miles (80 kilometers) altitude, high above [...]
