An Australian scientist has created the most detailed map ever of clouds of high-velocity gas in the Universe around us.
The map covers the entire sky and shows curious clouds of neutral hydrogen gas that are moving at a different speed to the normal rotation of the Milky Way. ...
The map was compiled by taking a picture of the sky and masking out gas that is moving at the same pace as the Milky Way to show the location of gas travelling at a different speed.
The result is the most sensitive and highest resolution all-sky map of high-velocity clouds ever created.
It shows the gas in spectacular detail, revealing never before seen filaments, branches and clumps within the clouds. ...
