Ancient Suns Set The Night Sky Aglow

Nearly the entire night sky glows a midnight blue from vast clouds of hydrogen gas. New observations made with the MUSE (Multi Instrument Spectroscopic Explorer) instrument on the European Southern Observatory’s Very Large Telescope have uncovered enormous cosmic reservoirs of atomic hydrogen surrounding distant galaxies. The team of astronomers discovered that the light — called Lyman-alpha…
