quasar

Astronomers have found the farthest known source of radio emissions in the universe: a galaxy-swallowing supermassive black hole.

In 2018, one of the brightest X-ray lights in the sky went dark, and scientists still aren't sure why.

The winds and radiation blowing out of quasars — the most energetic objects in the universe — can kill star formation galaxy-wide, new research shows.

Dark energy is even more mysterious than astronomers had thought, a new study suggests.

The fastest growing black hole in the known universe eats a mass the size of the sun every two days.

An enormous gas cloud in the early universe has a very small amount of the heavy elements that would form in later stellar generations, suggesting that it was "polluted" by the very first stars.

Sighting may help improve understanding of the early universe.
