Antares |
| Explanation |
Antares [ http://scienceweb.dao.nrc.ca/astro/skygaze060696.html ] is a huge star. In a class called red supergiant [ http://adsabs.harvard.edu/cgi-bin/nph-bib_query?1992AJ%2E%2E%2E%2E104%2E%2E821M&db_key=AST&nosetcookie=1 ], Antares is about 700 times the size of our own Sun [ http://antwrp.gsfc.nasa.gov/apod/lib/sun.html ], 15 times more massive, and 10,000 times brighter. Antares [ http://www.astro.wisc.edu/~dolan/constellations/hr/6134.html ] is the brightest star in the constellation of Scorpius [ http://www.astro.wisc.edu/~dolan/constellations/constellations/Scorpius.html ] and one of the brighter stars [ http://www.astro.wisc.edu/~dolan/constellations/extra/brightest.html ] in all the night sky. Antares [ http://www.seds.org/billa/twn/antx.html ] is surrounded by a nebula [ http://adsabs.harvard.edu/cgi-bin/nph-bib_query?1983ApJ%2E%2E%2E275%2E%2E704H&db_key=AST&nosetcookie=1 ] of gas which it has itself expelled. Radiation from Antares [ http://stardate.utexas.edu/radio/StarDateDB.FM$RETRIEVE?value=06/11/1996&field=ScriptAirDate&html=Test+Request+Date ]' blue stellar companion helps cause the nebular gas to glow, as photographed above. Antares [ http://www.travel-net.com/mickey/mh41.html ] is located about 500 light years away. |
