8P/Tuttle is a periodic comet in our solar system. It is currently approaching perihelion and in early December 2007 was visible telescopically to Northern Hemisphere observers near the pole star Polaris. On December 30, 2007 it was in close conjunction with spiral galaxy M33. On January 2, 2008 it passed Earth at a distance of only 0.25 AU. Later in the month it will become favorable to Southern hemisphere observers.

Comet 8P/Tuttle is responsible for the Ursid meteor shower in late December.

The 2007 Ursid meteor shower was expected to be stronger than usual due to the return of the comet.

A spiral galaxy about 144 million light-years away in the constellation Canis Major. The galaxy was discovered by John Herschel in 1835. So far three supernovae have been observed in NGC 2207 (SN 1975A, SN 1999ec and SN 2003H). NGC 2207 is in the process of tidal stripping IC 2163.

NGC 2207 is in the process of colliding and merging with IC 2163. Although they're still two separate spiral galaxies. They are only in the first step of colliding and merging. In about a billion years time they will merge and become an elliptical galaxy.

17P/Holmes is a periodic comet in our solar system, discovered by the British amateur astronomer Edwin Holmes on November 6, 1892. In only 42 hours in October 2007, the comet brightened from a magnitude of about 17 to about 2.8. This represents a change of brightness by a factor of about half a million and is the largest known outburst by a comet.

On November 9, 2007 the coma, the thin dissipating dust ball around the comet, was found to be the largest object in the solar system, with a diameter greater than that of the Sun. (Though by Solar System standards, the mass of the comet is minuscule.)

NGC 1360 is a rather amorphous cloud and was only identified as a planetary nebula by its strong radiation in the OIII (oxygen) band, due to excitation by the magnitude 9 central star. Planetary nebulae are normally symmetric, either as rings, spheres or bipolar structures. NGC1360 lies at an estimated 700 light years away from the galactic plane. The red matter towards the lower right is accepted to have been ejected from the original star before its final collapse and transformation into this unusual object.

The Rosette Nebula is a large, circular H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter. 5,200 light years from Earth and measuring roughly 130 light years in diameter. This star formation is currently still ongoing.

The Tarantula Nebula (also known as 30 Doradus, or NGC 2070) is an H II region in the Large Magellanic Cloud. It was originally thought to be a star, but in 1751 Nicolas Louis de Lacaille recognized its nebular nature.
