A meteor is a rocky or metallic body that enters the Earth’s atmosphere (or the atmosphere of another planet) from space at high speed and burns up; meteors that mostly survive the trip a...

Seyfert galaxies are distinguished by their bright nuclei and radiation from highly ionized atoms. Seyferts look much like quasars, but unlike point-like quasars the Seyfert host galaxies...

Proxima Centauri is the closest star to the Sun, and its planet, Proxima Cen b ("Proxima b"), lies in its habitable zone (the distance range within which surface water can be liquid), mak...

Cambridge, MA - An international team of scientists led by the Center for Astrophysics | Harvard & Smithsonian, has identified a problem with the growing interest in extractable reso...

The carbon atom can be easily ionized, more easily than hydrogen atoms for example. In star forming regions, where massive young stars emit ultraviolet light capable of ionizing atoms, al...

Cambridge, MA - Sparked by an image uploaded to Twitter, new research indicates that the light produced by black hole accretion may be bright enough to reflect off of dust, illuminating ...

Mergers of galaxy clusters are the most extreme events knwon in the universe, releasing the energy equivalent of up to a million galaxies shining for a million years. The shocks and turbu...

Cambridge, MA - Scientists today announced that they have observed the most luminous kilonova candidate on record, a find which challenges conventional theories of what happens in the aft...

A galactic bar is the approximately linear structure of stars and gas that stretches across the inner regions of some galaxies. The bar stretches from one inner spiral arm, across the nuc...
