Massive hydrogen clouds zipping through space mapped for the first time
Astronomer Dr. Tobais Westmeier at the University of Western Australia node of the International Centre for Radio Astronomy Research created a map that helps us understand these space phenomena. It revealed massive clouds of hydrogen: some are 80,000 light-years in diameter and have millions of times the mass of the sun. They move incredibly fast, between 43 and 56 miles per second. And they cover up to 13 percent of the sky.
