Tour: Astronomers Spy Quartet of Cavities From Giant Black Holes
Tour: Astronomers Spy Quartet of Cavities From Giant Black Holes
Scientists have found four enormous cavities, or bubbles, at the center of a galaxy cluster using NASA's Chandra X-ray Observatory. (2021-12-16)


NGC 3627 in 60 Seconds

View/Listen
Narrator (April Hobart, CXC): The spiral galaxy NGC 3627 is located about 30 million light years from Earth. Astronomers recently completed a survey of galaxies to look for supermassive black holes. Of the 62 galaxies, 37 - including NGC 3627 - were found to have X-ray sources at their centers and are candidates for being powered by supermassive black holes. Seven of these 37 were previously unknown. This result confirms other Chandra studies that show X-ray surveys are particularly good at finding supermassive black holes that are relatively inactive.
