Throwing y'all a little mid-day stardust. Astronomers have made the most detailed study yet of an extremely massive young galaxy cluster using three of NASA’s Great Observatories, as described in our latest press release. This multi-wavelength image shows this galaxy cluster, called IDCS J1426.5+3508 (IDCS 1426 for short), in X-rays from the Chandra X-ray Observatory in blue, visible light from the Hubble Space Telescope in green, and infrared light from the Spitzer Space Telescope in red. This rare galaxy cluster, which is located 10 billion light years from Earth, weighs almost 500 trillion Suns. This object has important implications for understanding how these mega-structures formed and evolved early in the Universe. #Astronomers have observed IDCS 1426 when the universe was less than a third of its current age. It is the most massive galaxy cluster detected at such an early age. Credit: NASA #NASA #Hubble #galaxy #universe #purple #Chandra #XRay
