If you estimated each spiral&#8217;s mass by how much light it emits, their fast rotations should break them apart. The leading hypothesis as to why these galaxies don&#8217;t break apart is dark matter &#8212; mass so dark we can&#8217;t see it. But these galaxies are even out-spinning this break-up limit &#8212; they are the fastest rotating disk galaxies known. It is therefore further hypothesized that their dark matter halos are so massive &#8212; and their spins so fast &#8212; that it is harder for them to form stars than regular spirals. If so, then these galaxies may be among the most massive spirals possible. Further study of surprising super-spirals like these will continue, likely including observations taken by NASA&#8217;s James Webb Space Telescope scheduled for launch in 2021. via NASA <a href=\"https:\/\/apod.nasa.gov\/apod\/ap191105.html\"><\/a><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Why are these galaxies spinning so fast?
