Astronomers have made the most detailed study yet of an extremely massive young galaxy cluster using three of NASA's Great Observatories. This multiwavelength image shows this galaxy cluster, called IDCS J1426.5+3508, in X-rays recorded by Chandra in blue, visible light observed by Hubble in green, and infrared light detected by Spitzer in red. is so far away that the light detected is from when the universe was roughly a quarter of its current age.
