Scientists believe a glow in space could be signs of another, alternate universe existing close to ours.
The mystery light, spotted by researchers studying images from the European Space Agency’s Planck telescope suggests that our universe could be bumping into a neighbouring one.
Modern theories about how the universe began suggest that our universe is just one among many that emerged from the Big Bang.
According to new research, the bright spots could be the remnants of light originating from hydrogen gas that was given off from the Big Bang.
These conclusions are based on research from Ranga-Ram Chary of the Planck’s US data centre in California. New Scientist first reported on his analysis, and stated that the "eerie glow" he had observed "could be due to matter from a neighbouring universe leaking into ours."
In order to arrive at this exciting conclusion, Chary and team compared the light leftover from the early universe -- seen in the map of the cosmic microwave background -- with an image of the sky taken by the European Space Agency’s Planck telescope.
The difference between the two revealed a mysterious spot of light.

"I would say most versions of inflation in fact lead to eternal inflation, producing a number of pocket universes,” Alan Guth of the Massachusetts Institute of Technology, told the New Scientist.
However, experts caution against getting too excited as previous mysterious patches of light have been explained by space dust.
“I suspect that it would be worth looking into alternative possibilities,” theoretical astrophysicist David Spergel told the New Scientist.
“The dust properties are more complicated than we have been assuming, and I think that this is a more plausible explanation.”
