UGC 12591: The Fastest Rotating Galaxy Known


Even identifying which type of galaxy UGC 12591 is difficult -- 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 -- 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.

  1. 480 km/s is sorta meaningless, unless you specify and point on the disc. The rotational speed ought to be given as radians (or degrees) per second.

  2. From what I have read, the galaxy tends to rotate as fast as the supermassive black hole in the center rotates. This one must be screaming.

  3. Did you realize there is a 12 word phrase you can tell your partner... that will trigger deep emotions of love and impulsive attractiveness for you deep inside his chest?

    Because hidden in these 12 words is a "secret signal" that triggers a man's instinct to love, look after and protect you with all his heart...

    This instinct is so hardwired into a man's mind that it will drive him to try better than ever before to to be the best lover he can be.

    Matter of fact, fueling this powerful instinct is so binding to having the best ever relationship with your man that as soon as you send your man one of these "Secret Signals"...

    ...You'll immediately notice him open his heart and soul for you in such a way he haven't expressed before and he'll identify you as the one and only woman in the universe who has ever truly tempted him.
