M100: A Grand Design
| Title |
M100: A Grand Design |
| Explanation |
Majestic [ http://www.lhl.lib.mo.us/pubserv/hos/stars/welcome.htm ] on a truly cosmic scale, M100 [ http://bozo.lpl.arizona.edu/messier/m/m100.html ] is appropriately known as a Grand Design spiral [ http://antwrp.gsfc.nasa.gov/apod/ap961030.html ] galaxy. A large galaxy of over 100 billion or so stars with well defined spiral arms [ http://antwrp.gsfc.nasa.gov/apod/ap960409.html ], it is similar to our own Milky Way [ http://antwrp.gsfc.nasa.gov/apod/ap970315.html ]. One of the brightest members of the Virgo Cluster of galaxies [ http://bozo.lpl.arizona.edu/messier/more/virgo.html ] , M100 (alias NGC 4321) is 56 million light-years distant in the spring constellation of Coma Berenices [ http://www.astro.wisc.edu/~dolan/constellations/ constellations/Coma_Berenices.html ]. This Hubble Space Telescope image [ http://oposite.stsci.edu/pubinfo/PR/94/01.html ] of the central region of M100 was made in 1993 with the Wide Field and Planetary Camera 2. It reveals the bright blue star clusters [ http://antwrp.gsfc.nasa.gov/apod/ap980329.html ] and intricate winding dust lanes [ http://antwrp.gsfc.nasa.gov/apod/ap980116.html ] which are hallmarks of this class of galaxies [ http://hermes.astro.washington.edu:80/scied/astro/hubble/hubble.html ]. Studies of stars in M100 [ http://antwrp.gsfc.nasa.gov/apod/ap960110.html ] have recently played an important role in determining the size and age [ http://antwrp.gsfc.nasa.gov/diamond_jubilee/ debate_1996.html ] of the Universe. |
