Observations from the European Southern Observatory's Very Large Telescope have shed light on the power source of a rare vast cloud of glowing gas in the early Universe. The observations show for the first time that this giant "Lyman-alpha blob" -- one of the largest single objects known -- must be powered by galaxies embedded within it.I remain unconcerned.
"We have shown for the first time that the glow of this enigmatic object is scattered light from brilliant galaxies hidden within, rather than the gas throughout the cloud itself shining." explains Matthew Hayes (University of Toulouse, France), lead author of the paper.
