Everything Space Four independent teams of scientists, whose results appear as separate papers in The Astrophysical Journal, used Chandra to detect intergalactic gas with temperatures ranging from 300,000 to 5 million degrees Celsius. This gas forms part of a gigantic system of hot gas and dark matter that defines the cosmic landscape. The gaseous component alone contains more material than all the stars in the universe.
“We had strong suspicions from the Big Bang theory and observations of the early universe that this gas exists in the present era, but like a stealth aircraft it had eluded our detection,” said Claude Canizares of the
