Title:
Close-Up of the Lagoon
Explanation:
Stars are battling gas and dust in the Lagoon Nebula but the photographers are winning. Also known as M8, this photogenic nebula [ http://www.cfht.haw…] is visible [ http://antwrp.gsfc.…] even without binoculars towards the constellation [ http://www.astro.wi…] of Sagittarius [ http://www.astro.wi…]. The energetic processes of star formation [ http://antwrp.gsfc.…] create not only the colors but the chaos [ http://antwrp.gsfc.…]. The red-glowing gas [ http://antwrp.gsfc.…] results from high-energy starlight striking interstellar hydrogen [ http://pearl1.lanl.…] gas. The dark dust [ http://antwrp.gsfc.…] filaments [ http://antwrp.gsfc.…] that lace M8 [ http://www.seds.org…] were created in the atmospheres of cool giant stars [ http://www.astro.ke…] and in the debris [ http://antwrp.gsfc.…] from supernovae [ http://imagine.gsfc…] explosions. This spectacular portion of the Lagoon Nebula [ http://antwrp.gsfc.…] taken by the CFHT [ http://www.cfht.haw…] was created from light emitted by hydrogen (shown in red) and light emitted by oxygen [ http://pearl1.lanl.…] (shown in green). The light from M8 [ http://antwrp.gsfc.…] we see today left about 5000 years ago. Light takes about 50 years to cross this section of M8 [ http://www.seds.org…].
