Out in the Andromeda galaxy is a newly discovered comet. The C/2007 L1 is one of the most unusual structures that astronomers have ever seen.
On October 31st, 2007, astro-photographer Pedro Torres of Puebla, Mexico, took a close-up picture of the comet's core. Pedro used a combination of two 120-second exposures obtained using a 30-cm reflector, a Sigma 6303 CCD camera, and a blue filter.
The photograph was taken at a perihelion distance of 1.07 AU. What it reveals is startling new structure in the center of comet C/2007 L1. The whole of the coma is very brilliant and unusually, the nucleus containing two extra bright eyes. The comet's tail was not curved thus producing a circular effect.
Pedro has applied to the International Astronomical Union (IAU) for the official name of comet C/2007 L1 to be called 'Halloween'. See picture to the right:-
