Today's Picture

Comet 41P/Tuttle-Giacobini-Kresak poses for a Messier moment in this telescopic snapshot from March 21.In fact it shares the 1 degree widefield-of-view with two well-known entries in the 18th centurycomet-hunting astronomer's famous catalog .Sweeping through northern springtime skies justbelow the Big Dipper , the faint greenish cometwas about 75 light- seconds from our fair planet.Dusty, edge-on spiral galaxy Messier 108 (bottom center) is morelike 45 million light-years away.At upper right, the planetary nebula with an aging but intenselyhot central star, the owlish Messier 97 is onlyabout 12 thousand light-yearsdistant though, still well within our own Milky Way galaxy. Named for its discoverer and re-discoverers, this faint periodic comet wasfirst sighted in 1858 and not again until 1907 and 1951.Matching orbit calculations indicated that the same comet had beenobserved at widely separated times.Nearing its best apparition and closest approach to Earth in over 100 years on April 1, comet 41P orbits the Sun with a period of about 5.4 years.
