Title:
The Dark River to Antares
Explanation:
Connecting the Pipe Nebula [ http://antwrp.gsfc.…] to the bright star Antares is a flowing dark cloud nicknamed the Dark River [ http://www.astropix…]. The murkiness of the Dark River [ http://antwrp.gsfc.…] is caused by absorption of background starlight by dust [ http://antwrp.gsfc.…], although the nebula contains mostly hydrogen [ http://pearl1.lanl.…] and molecular gas. Antares [ http://www.astro.ui…], the brightest star in the frame, is embedded in the colorful Rho Ophiuchi [ http://antwrp.gsfc.…] nebula clouds. The Dark River, pictured above [ http://www.starrysc…] across the upper left, spans over 20 times the angular diameter of the Moon [ http://antwrp.gsfc.…] and lies about 500 light years [ http://chandra.harv…] distant. Other types of nebula [ http://www.seds.org…] visible here include red emission nebula [ http://antwrp.gsfc.…] and the blue reflection [ http://antwrp.gsfc.…] nebula.
