Title:
A Supernova in Nearby Galaxy NGC 2403
Explanation:
The closest and brightest supernova in over a decade was recorded [ http://www.berkeley…] just over a month ago in the outskirts of nearby galaxy NGC 2403. Officially tagged SN 2004dj [ http://www.rochester astronomy.org//sn200 4/sn2004dj.html ], the Type IIP [ http://www2.arnes.s…] explosion likely annihilated most of a blue supergiant star [ http://antwrp.gsfc.…] as central fusion [ http://zebu.uoregon…] could no longer hold it up [ http://antwrp.gsfc.…]. The supernova [ http://heasarc.gsfc…] can be seen as the bright object in the above image [ http://hubblesite.o…] in the direction of the arrow. The home galaxy to the supernova, spiral galaxy NGC 2403 [ http://www.seds.org…], is located only 11 million light years [ http://starchild.gs…] away and is visible with binoculars toward the northern constellation [ http://www.astro.wi…] of Camelopardalis [ http://www.astronom…] (the Giraffe [ http://www.kidsplan…]). The supernova is fading [ http://www.rocheste…] but still visible with a telescope, once peaking at just brighter than magnitude [ http://csep10.phys.…] 12. Supernovas [ http://cfa-www.harv…] of this type change brightness in a predictable way and may be searched for in the distant universe [ http://antwrp.gsfc.…] as distance indicators.
