| 説明 | Galaxy clusters are enormous collections of hundreds or even thousands of galaxies and vast reservoirs of hot gas embedded in massive clouds of dark matter, invisible material that does not emit or absorb light, but can be detected through its gravitational effects.Located about 4.3 billion light-years from Earth, MACS J0416.1-2403 is a pair of colliding galaxy clusters that will eventually combine to form an even bigger cluster.This image of MACS J0416 includes data from two other telescopes in addition to the Hubble Space Telescope: NASA's Chandra X-ray Observatory (diffuse emission in blue) and the National Science Foundation's Karl G. Jansky Very Large Array (diffuse emission in pink). Where the X-ray and radio emission overlap, the image appears purple. Astronomers also used data from the Giant Metrewave Radio Telescope in India in studying the properties of MACS J0416.The Chandra data show gas in the merging clusters with temperatures of millions of degrees. The Hubble data show galaxies in the clusters and other, more distant, galaxies lying behind the clusters. Some of these background galaxies are highly distorted and magnified because of gravitational lensing, the bending of light by massive objects. Finally, the structures in the radio data trace enormous shock waves and turbulence. The shocks are similar to sonic booms, generated by the mergers of the clusters.For more information, visit: hubblesite.org/contents/news-releases/2016/news-2016-08.htmlFor a Hubble-only image of MACS J0416, see: hubblesite.org/contents/media/images/2015/45/3662-Image.h...Credit: NASA, ESA, CXC, NRAO/AUI/NSF, STScI, R. van Weeren (Harvard-Smithsonian Center for Astrophysics), and G.
