Nasa spots mysterious light as bright as ALL known galaxies combined
Nasa has detected a surprising surplus of infrared light in the dark space between galaxies. Baffled astronomers say the lights is a diffuse cosmic glow as bright as all known galaxies combined.
They believe it could be from orphaned stars flung out of galaxies.
The findings redefine what scientists think of as galaxies, Nasa said.
Galaxies may not have a set boundary of stars, but instead stretch out to great distances, forming a vast, interconnected sea of stars.
‘We think stars are being scattered out into space during galaxy collisions,’ said Michael Zemcov, lead author of a new paper describing the results from the rocket project and an astronomer at the California Institute of Technology (Caltech) and NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California.
‘While we have previously observed cases where stars are flung from galaxies in a tidal stream, our new measurement implies this process is widespread.’
