From a NOIRLab press releases, for which this image was commissioned: 'Astronomers studying a powerful gamma-ray burst (GRB) with the Gemini South telescope, operated by NSF’s NOIRLab, may have detected a never-before-seen way to destroy a star. Un...

Artwork of an active galactic nucleus, or AGN. Many, perhaps most large galaxies, are thought to harbour supermassive black holes in their central regions. These enormous gravitational powerhouses can weigh anything from a few hundred thousand to sev...
