Rough Cosmic Waters: Chandra X-ray Observatory Reveals 'Turbulent' Effect of Black Holes

From NASA: “Chandra observations of the Perseus and Virgo galaxy clusters suggest turbulence may be preventing hot gas there from cooling, addressing a long-standing question of galaxy clusters do not form large numbers of stars.” Image Credit: NASA/CXC/Stanford/I. Zhuravleva et al

This week, NASA announced that the Chandra X-ray Observatory, now in its 15th […]

In an effort to understand how black holes shape the evolution of galaxies, astronomers spent eight months creating a series of time-lapse movies from 400 observations made by NASA’s Hubble Space Telescope. The movies, taken from observations conducted over a 13-year period from 1995-2008, show a […]
