The research of exoplanet atmospheres primarily focuses on bodies known as ultra-hot Jupiters. As the name suggests, these are very large and very hot exoplanets.

Astronomers have observed the brightest flash of light ever seen, released from a gamma-ray burst (GRB) which occurred 2.4 billion light years from earth.

For now, there are no known astronomical objects that pose any meaningful threat to Earth.

Astronomers at MIT have discovered a stellar binary system named ZTF J1813+4251 with an extremely short orbit, the two stars circling each other every 51 minutes.

All currently identified stars can be split into two populations or generations. The first is the set of youngest stars. These are metal rich and very hot.

The moon is believed to have formed as a result of a collision around 4.5 billion years ago between a young earth and Theia, a mars-sized body from the gradual cumulation of impact debris.
