In the halo of the Milky Way, there are mysterious clouds that zoom through space at high speeds – and we may have finally unlocked a key that will help us understand them. Using telescopes, a scientist has created a detailed map of the clouds, revealing clumps, branches and filaments that have never been seen before.
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.
Scientists don’t know where these clouds originated, but some suggest that they could be leftover material from the formation of the galaxy, material falling into or out of our galaxy, or from interaction with nearby Large and Small Magellanic clouds. Dr. Westmeier has made the map available to anyone so that we can continue to learn more about these incredible formations.
