--------- #1320 - Supernova Sn1006
- Attachment: See image of Sn1006
- When Supernova Sn1006 first explode in the year 1006 it was brighter than the planet Venus in the night sky. It was even visible during the day for several weeks after the explosion even though it was 7,000 lightyears away.
- Today astronomers are studying the remnants, the debris that is still escaping the original explosion. What they conclude is that it was a Type1a Supernova. (See Review #1318 Kepler’s Supernova to get more explanation of what causes this type of supernova).
- The tell tale signs of a Type1a is the large amounts of the element iron in the debris. This heaviest of elements in a star would have been at the core and the core is blown away. The other sign is that there is no Neutron Star or Blackhole left at the core of the explosion. When a super massive star explodes it leaves a core behind, this explosion did not. A 1.4 Solar Mass supernova explosion evaporates everything.
- The image that is attached is a composite picture taken by 4 different telescopes.
