Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered a surprising connection between a supermassive black hole and the galaxy where it resides. Powerful radio jets from the black hole – which normally suppress star formation – are stimulating the production of cold gas in the galaxy’s extended halo […]

Black-Hole-Powered Jets Forge Fuel for Star Formation





ESO telescopes help reinterpret brilliant explosion An extraordinarily brilliant point of light seen in a distant galaxy, and dubbed ASASSN-15lh, was thought to be the brightest supernova ever seen. But new observations from several observatories, including ESO, have now cast doubt on this classification. Instead, a group of astronomers propose […]

Spinning Black Hole Swallowing Star Explains Superluminous Event


Astronomers have found a pair of extraordinary cosmic objects that dramatically burst in X-rays. This discovery, obtained with NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton observatory, may represent a new class of explosive events found in space. The mysterious X-ray sources flare up and become about a hundred times brighter […]
