M. Kornmesser/ESO An artist’s illustration shows a massive black hole awakening at the center of a distant galaxy. The black hole pulls in a growing disk of material as it feeds on surrounding gas, making the galaxy brighter. Sign up for CNN’s Wonder Theory science newsletter.

In December 2019, astronomers were stunned when the core of a relatively quiet galaxy 300 million light-years away abruptly lit up like a Christmas tree and shone brighter than we’ve ever seen it. A giant black hole that accelerated and started slurping material from the space around it is the best explanation for such a … Read more

A swirling black hole hiding within the features of the black holes that merged to create it. Credit: Robert Lea Astronomers believe that at the heart of most, if not all, galaxies lies a gigantic black hole with a mass millions or even billions of times greater than that of our Sun. These supermassive black … Read more
This illustration shows two quasars in the process of merging. Using both the Gemini North Telescope, one half of the International Gemini Observatory, which is supported in part by the U.S. National Science Foundation and managed by NSF NOIRLAb, and the Subaru Telescope, a team of astronomers has observed a pair of merging quasars discovered … Read more
Fast radio bursts (FRBs) are intense, short-lived bursts of radio waves originating from outside the Milky Way that can emit the same amount of energy in just thousandths of a second as it takes the Sun three days to emit. However, despite their power and the fact that up to 10,000 FRBs can erupt in … Read more

Astronomers have made a groundbreaking discovery using NASA’s Atacama Large Millimeter/submillimeter Array (ALMA) and James Webb Space Telescope (JWST). They observed twoin disks and parallel jets erupting from a few young stars in the star system WL20, located more than 400 light-years away in the rho Ophiuchi molecular cloud complex. This unexpected finding provides new … Read more
