To start, even identifying which type of galaxy UGC 12591 is difficult &#8212; it has dark dust lanes like a spiral galaxy but a large diffuse bulge of stars like a lenticular. Surprisingly observations show that UGC 12591 spins at about 480 km\/sec, almost twice as fast as our Milky Way, and the fastest rotation rate yet measured. The mass needed to hold together a galaxy spinning this fast is several times the mass of our Milky Way Galaxy. Progenitor scenarios for UGC 12591 include slow growth by accreting ambient matter, or rapid growth through a recent galaxy collision or collisions &#8212; future observations may tell. The light we see today from UGC 12591 left about 400 million light years ago, when trees were first developing on Earth.<\/p><\/blockquote>\n<p><img decoding=\"async\" src=\"https:\/\/lh3.googleusercontent.com\/-1LLQG4swaM8\/WL5CWq9kufI\/AAAAAAABdAM\/1SxQ_VYKI0osBEkMrsDYK0hqba-LmegTwCJoC\/w4000-h3331\/UGC12591_Hubble_4000.jpg\" alt=\"\" \/><\/p>\n<p>Import\u00e9 de <a href=\"https:\/\/plus.google.com\/104239776541827516598\/posts\/7PBKTG73Kdu\">Google+<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Google+ reshared post UGC 12591: The Fastest Rotating Galaxy KnownImage Credit: +NASA, +European Space Agency, ESA, Hubblehttps:\/\/apod.nasa.gov\/apod\/ap170307.html Why does this galaxy spin so fast?
