Astronomers have identified a bright hydrogen emission from a galaxy in the very early universe. The surprise finding is ...

ESA’s Euclid mission mapped 26 million galaxies, revealing galaxy shapes, cosmic structures, and gravitational lenses ...

What's on and in a star? What happens in an active galactic nucleus? Answering those questions is the goal of a proposed ...

The most massive black holes can cover galaxies with immense radiation. However, this need not be harmful for possible ...

An international team of researchers used multi-wavelength observations of active galactic nuclei to study how black holes launch relativistic jets. The sixteen sources were observed with the Event ...

New research reveals that high-energy radiation from active galactic nuclei could foster life on distant planets by ...

At the center of most large galaxies, including our own Milky Way, sits a supermassive black hole. Interstellar gas periodically falls into the orbit ...

A surprising new study from Dartmouth and the University of Exeter researchers shows that when the supermassive black holes at the center of most large galaxies—including the Milky Way—consume ...

At the heart of most large galaxies, including our own Milky Way, lurks a supermassive black hole. These cosmic giants ...

Although black hole radiation can be catastrophic in some cases, it may assist life once oxygen has accumulated in the planet ...

At the center of most large galaxies, including our Milky Way, sits a supermassive black hole. These powerful objects sometimes enter active galactic nucleus (AGN) mode, where they pull in gas and ...

He notes that while this is a promising candidate for a supermassive black hole merger, interpreting light from the region around an SMBH-known as the active galactic nucleus (AGN)-is complex.
