- On May 1, 1006 A.D., a new star appeared in Earth’s night sky. It was far brighter than Venus and visible during the daytime for weeks. Astronomers in China, Japan, Europe, and the Arab world all documented it. Today, we know it was a supernova, or colossal explosion of a white dwarf star, which sent its star material hurtling into space.

May 23, 2018 · What did the supernova of 1006 look like? When this “guest star” appeared in the constellation Lupus between April 17th and May 1st in the year 1006 AD, observers that were spread over much of the known world, including China, Japan, Egypt, modern-day Iraq, and Europe, described it as being at least sixteen times as bright as Venus.
Apr 17, 2013 · SN 1006 is a supernova remnant, a cloud of star debris initiated by a colossal stellar explosion in the year 1006. The debris has been expanding outward that year. Learn more on EarthSky.
Dec 28, 2023 · SN 1006, a supernova observed over a millennium ago, has been extensively studied using NASA’s Chandra and IXPE telescopes, revealing critical details about its magnetic field and particle acceleration, contributing to our understanding of cosmic rays.
Sep 26, 2012 · A supernova that lit up the skies in the year 1006 lived and died fast, leaving no companion star behind, astronomers have found. The result is the latest clue in a puzzle that has been troubling...

At its height, a supernova can shine as brightly as several hundred million Suns, reaching an absolute magnitude of around —19. Hence even without optical aid such a spectacular explosion may be detected at a distance of a few kiloparsec. After the original flare-up, the decline in brightness is very gradual, over a period of several years. Further...
It comes as no surprise to find that the most careful observations of the new star of 1006 originate from East Asia. Around this time, oriental astronomers were the only observers to maintain a systematic watch of the night sky. Their main motive was astrological; celestial changes were regarded as presaging important terrestrial events. In China, ...
Arab astronomers in general tended to show little interest in sporadic (and hence unpredictable) phenomena such as comets and new stars; they were much more concerned with cyclic (and hence predictable) events involving the Moon and planets. According to Aristotle, whose views were widely accepted in the medieval Arab world, the heavens were immuta...
Chinese, Japanese and Arab sources agree closely on the date of first appearance of the new star in 1006. As noted above, a date of 30 April may be deduced from the rather cryptic information given by Ali ibn Ridwan. A Chinese work, the Song Huiyao, indicates a discovery date of 1 May, as does the Japanese Meigetsuki. However, although a further Ch...
Despite the extreme southerly location of the supernova, Chinese, Arab and European records separately testify to its superlative brilliance around maximum phase, often comparing its brightness with that of the Moon! In China, one source reported that the star was “huge”, adding that “its bright rays were like a golden disc”. The Songshiaffirmed th...
The most careful East Asian observations of the star's position are from China and are contained in the Song Huiyao and Songshi. These are as follows. (i) “It appeared to the east of Kulou and to the west of Qiguan… Its position was measured as 3° in Di (lunar lodge).” (ii) “It appeared to the south of Di and 1° west of Qiguan.” Japanese observers ...
The SNR G327.6+14.6 was first firmly identified as the remnant of SN 1006 by Milne (1971). This remnant has been extensively studied at high resolution in both radio and X-ray wavelengths. The SNR is a limb-brightened shell with no central condensation (see figure 1). Its location at high galactic latitude is more in keeping with an outburst of a s...

Oct 26, 2023 · NASA’s IXPE telescope has captured the first polarized X-ray imagery of the supernova remnant SN 1006, expanding our understanding of the relationship between magnetic fields and the energy streaming away from exploding stars.
Apr 29, 2016 · In April of the year 1006 A.D., spectators around the world were treated to a resplendent display—a supernova, now called SN 1006, that reportedly shone brighter than Venus.
