APOD: NGC 6334: The Cat's Paw Nebula (2014 Jun 18) Image Credit & Copyright: Roberto Colombari and SONEAR Obs.; Color data: Robert Gendler & Ryan Hannahoe http://apod.nasa.gov/apod/ap140618.html Explanation: Nebulas are perhaps as famous for being identified with familiar shapes as perhaps cats are for getting into trouble. Still, no known cat could have created the vast Cat's Paw Nebula visible in Scorpius. At 5,500 light years distant, Cat's Paw is an emission nebula with a red color that originates from an abundance of ionized hydrogen atoms. Alternatively known as the Bear Claw Nebula or NGC 6334, stars nearly ten times the mass of our Sun have been born there in only the past few million years. Pictured above is a deep field image of the Cat's Paw nebula. http://www.astrobin.com/users/rob77/ http://www.observatorio-phoenix.org/t_proj/Sonear/sonear.htm http://www.robgendlerastropics.com/ http://ryanhannahoe.nmskies.com/ Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=140618 #APOD
