Previous studies have shown that it is dominated by hot dust whose temperatures reach 450 Kelvin or almost 180 degrees Celsius. The high temperature of this range suggests the domination of an active galactic nucleus (AGN).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>New observations from the James Webb Space Telescope have revealed fresh details about one of the most luminous known objects in the universe: the dust-shrouded quasar W2246\u22120526, seen just 1.2 billion years after the Big Bang.
