Here’s something you don’t see every day; an exploding comet. In fact the last time this comet did this was in 1892.
Comet 17P/Holmes is now larger than Jupiter. Astronomer Eric Allen of Quebec’s Observatoire du Cégep de Trois-Rivières combined images he captured on three consecutive nights (Oct. 25, 26 and 27) and placed them beside a picture of Jupiter scaled to the same distance as the comet, as shown above.

The comet is visible to the naked eye, and looks even better through a telescope. This would be a good excuse to go visit the Chico Community Observatory in upper Bidwell Park Sunday night and have them swing the telescope by for a look. Or if you want to spot it yourself, here is a sky map.
