We're here for the cozy cosmos! In this @nasachandraxray image, two groups of galaxies rush together and produce warmth.⁣
⁣
Most galaxies don't exist in isolation. They're bound to other galaxies through gravity — either in relatively small numbers known as “galaxy groups” or larger concentrations called “galaxy clusters” consisting of hundreds or thousands of galaxies. ⁣
⁣
The system of galaxies is called NGC 6338, located about 380 million light-years from Earth, with a mass within about 100 trillion times the mass of the Sun. In this composite image, X-ray data from Chandra in red shows hot gas with temperatures upward of about 20 million degrees Celsius. Cooler gas detected with Chandra and @europeanspaceagency's XMM-Newton is shown in blue. Optical data from the Sloan Digital Sky Survey shows galaxies and stars in white.⁣
