quasars

New Hubble Space Telescope images of a black hole-powered quasar reveal 'weird' structures and gigantic jets of energy that scientists are just beginning to explain.

By using protons to probe how a magnetic field responds to an expanding plasma, experimenters have replicated the particle jets spewed out by active black holes.

Two superluminous quasars, or active black holes at the centers of large galaxies, were found just 900 million years after the Big Bang — the earliest detection of a pair of merging quasars ever seen.

Astronomers using the James Webb Space Telescope have separated the light of a quasar from the light of its surrounding stars, offering unprecedented insight into how the universe's oldest black holes grew.

Scientists think that by studying a cluster of "baby quasars," they can get a better understanding of supermassive black holes in the early universe.

Observations made by Chile's ALMA telescope have revealed a gigantic quasar quenching a galaxy's star formation — a first-of-its-kind observation in the early universe.

The newly identified quasar, observed 13.7 billion light-years away by the James Webb Space Telescope and Chandra X-ray Observatory, could be an example of a heavy black hole "seed" in the early universe.

The European Space Agency's Gaia telescope revealed half a million newfound stars, and detailed the orbits of over 150,000 asteroids.

Studying the mysterious form of matter around ancient quasar galaxies could have profound implications for our understanding of how the cosmos evolved.

The observation that the universe appears to run slower in the past was made by scrutinizing the light emitted by gigantic quasars.
