SN 1006: History's Brightest Supernova

Explanation:
|
Suddenly, in the year 1006 AD, a new star [ http://www.noao.edu…] appeared in the sky. Over the course of just a few days, the rogue star became brighter than the planet Venus [ http://www.nineplan…]. The star, likely the talk of everyone who could see it, was recorded by people who lived in areas now known as China [ http://www.cia.gov/…], Egypt [ http://www.cia.gov/…], Iraq [ http://www.cia.gov/…], Italy [ http://www.cia.gov/…], Japan [ http://www.cia.gov/…], and Switzerland [ http://www.cia.gov/…]. The celestial newcomer, now known to be a supernova [ http://heasarc.gsfc…], took months to fade. Modern observations have been used to measure the speed of the still-expanding shock wave [ http://antwrp.gsfc.…], allowing a better estimate of its distance [ http://www.astro.uc…] and hence a better estimate of the true brightness of the supernova [ http://antwrp.gsfc.…]. It turns out SN 1006 [ http://www.seds.org…] likely achieved an apparent visual magnitude [ http://www.phys.ksu…] of -7.5, making it the brightest supernova [ http://wave.xray.mp…] on record. The shock wave was imaged in 1998 from CTIO [ http://www.ctio.noa…] (left panel), and then subtracted from a similar image taken in 1986 (right panel), highlighting the relative expansion.
