APOD: M1: The Incredible Expanding Crab (2013 Sep 05) Credit & Copyright: Adam Block, Mt. Lemmon SkyCenter, U. Arizona http://apod.nasa.gov/apod/ap130905.html Explanation: The Crab Nebula is cataloged as M1, the first on Charles Messier's famous list of things which are not comets. In fact, the Crab is now known to be a supernova remnant, an expanding cloud of debris from the explosion of a massive star. The violent birth of the Crab was witnessed by astronomers in the year 1054. Roughly 10 light-years across today, the nebula is still expanding at a rate of over 1,000 kilometers per second. Want to watch the Crab Nebula expand? Check out this video (vimeo) animation comparing an image of M1 taken in 1999 at the European Southern Observatory, with this one, taken in 2012 at the Mt. Lemmon Sky Center. Background stars were used to register the two images. The Crab Nebula lies about 6,500 light-years away in the constellation Taurus. http://www.caelumobservatory.com/ http://skycenter.arizona.edu/ http://vimeo.com/71117055 Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130905 #APOD

APOD: Skylab Over Earth (2013 Aug 18) Image Credit: Skylab, NASA http://apod.nasa.gov/apod/ap130818.html Explanation: Skylab was an orbiting laboratory launched by a Saturn V rocket in May 1973. Skylab, pictured above, was visited three times by NASA astronauts who sometimes stayed as long as two and a half months. Many scientific tests were performed on Skylab, including astronomical observations in ultraviolet and X-ray light. Some of these observations yielded valuable information about Comet Kohoutek, our Sun and about the mysterious X-ray background - radiation that comes from all over the sky. Skylab fell back to earth on 1979 July 11. http://www.nasa.gov/mission_pages/skylab/ Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130818 #APOD
