• Astronomers have spotted an enormous, glowing blob of gas in the distant universe, with no obvious source of power for the light it is emitting.
• Enormous Lyman-alpha nebula” (ELAN), it is the brightest and among the largest of these rare objects, only a handful of which have been observed, the researchers said.
• The newly discovered nebula was found at a distance of 10 billion light years in the middle of a region with an extraordinary concentration of galaxies.
• Researchers found this massive overdensity of early galaxies, called a “protocluster,” through a novel survey project.
• The newly discovered ELAN is known as MAMMOTH-1.
