'''Tycho's Supernova''' (SN 1572, B Cassiopeiae) was a [[supernova]] that occurred in the [[constellation]] of [[Cassiopeia]].<ref name=britannica>[https://www.britannica.com/place/Tychos-Nova Tycho's Nova] from britannica.com</ref> Occurring in 1572, it was one of the earliest supernovae recorded in the [[Milky Way]]. It is named after [[Tycho Brahe]] who noticed a bright [[star]] where there had been none previously on the night sky.<ref name=seds/> It reached a peak [[star magnitude|magnitude]] of -4, making it a similar brightness to the planet [[Venus]].
==History==
The supernova is named after [[Tycho Brahe]] who observed a [[star]] that he did not recognise near the [[zenith]] while walking home on November 11, 1572.<ref>[http://www.skyandtelescope.com/astronomy-news/new-insights-on-tychos-supernova/ New Insights on Tycho's Supernova] from skyandtelescope.com</ref> However he was not the first person to see the supernova; some claim to have seen it in August but W. Schuler saw it a week earlier than Tycho on November 5, 1572.<ref name=seds/> Initially it was the same brightness as [[Jupiter]] but quickly reached the same brightness as [[Venus]], and could be observed during the day for around 2 weeks. It began to fade at the end of November and also became redder. After 16 months was no longer visible to the naked eye after March 1574.<ref name=seds/>
Tycho's observation of the supernova ultimately lead to his life long interest in [[astronomy]]. He performed precise measurements to demonstrate that it was not a nearby object such as a [[comet]] but significantly further away, comparable to the distances of stars.<ref name=britannica/> Much later in the 1960s, extraordinarily faint nebulosity was discovered in the position Tycho recorded the supernova as being.<ref name=seds/> This was taken to be the remnant of the supernova. No stellar remnant has been seen. In 2008 it was shown to be a Type Ia supernova.
==Properties and Structure==
The nebula is around 3,500 [[light year]]s away and is 3.7 arcminutes across.<ref name=nasa/> The nebula contains a [[radio wave|radio]] source catalogued as 3C 10 and also an [[x-ray]] source.<ref name=seds/> The [[gas]] of the nebula is expanding extremely rapidly at some 9,000 km/s.<ref name=seds/> This is much faster than other nebulae such as the [[Crab Nebula]] which is expanding at only 1,000 km/s. [[Infrared]] images have shown the shockwave produced by the supernova has heated [[dust]].<ref name=nasa/>
