To start, even identifying which type of galaxy UGC 12591 is difficult &#8212; featured on the lower left, 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 years ago, when trees were first developing on Earth. via NASA <a href=\"https:\/\/apod.nasa.gov\/apod\/ap200219.html\"><\/a><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Why does this galaxy spin so fast?
