There are clouds dancing around the Milky way, as well as other galaxies, and even around the universe. At least, that’s what astronomers have determined. And they’ve mapped the results for all to see.
Astronomers have mapped mysterious clouds of high-velocity hydrogen swirling around the Milky Way and other nearby galaxies.
Experts say the local universe is home to ‘curious’ clouds of neutral hydrogen gas, with the material covering up to 13 percent of the sky.
These clouds, however, are known to be moving at different speeds than that of the normal rotation of the Milky Way.
‘These gas clouds are moving towards or away from us at speeds of up to a few hundred kilometers per second,’ said Dr Tobias Westmeier, from the University of Western Australia branch of the International Centre for Radio Astronomy Research.
‘They are clearly separate objects.’
To map the mysterious phenomenon, the team used data from the HI4PI survey of the entire sky, which combined observations from CSIRO’s Parkes Observatory in Australia and the Effelsberg 100m Radio Telescope operated by the Max-Planck Institute for Radio Astronomy in Germany.
Then, they omitted the gas that is moving at the same rate as the Milky Way, revealing the outliers.
