 Just over a thousand years ago, the stellar explosion known as Supernova 10.06 was observed. It was brighter than Venus and visible during the day, for weeks. The brightest supernova ever recorded on Earth, this spectacular light show, was documented in China, Japan, Europe, and the Arab world. Ancient observers were treated to the celestial fireworks display without understanding its cause or implications. We now understand that SN1006 was a Type 1A supernova. In 1976, the first detection of exceedingly faint optical emissions of the supernova remnant were recorded. A tiny portion of this filament is revealed in detail by this Hubble observation. The twisting ribbon of light corresponds to locations where the expanding blast wave from the supernova is now sweeping into very tenuous surrounding gas. The size of the remnant implies that the blast wave from the supernova had expanded at nearly 32 million kilometers per hour. That's 20 million miles per hour, every hour, for over 1,000 years.
