"Doomsday Comet" Elenin was briefly famous for inaccurate predictions that it might hit Earth. Instead it disintegrated as it approached the sun last month. (Doomsday canceled.) Over the weekend, Italian astronomer Rolando Ligustri spotted the comet's remains. It's the elongated cloud in this Oct. 22nd photo of the star field where Elenin would have appeared if it were still intact:

Another team of astronomers--Ernesto Guido, Giovanni Sostero and Nick Howes--spotted the cloud on the same night. At first they were skeptical. "The cloud was extremely faint and diffuse," says Guido. "We wondered if it might be scattered moonlight or some other transient artifact." But when the team looked again on Oct. 23, the cloud was still there. A two-night
blink animation shows that the cloud is moving just as the original comet would have. Note: Some readers have noticed a fast-moving streak to the to the lower right of the debris cloud. That is an unrelated asteroid, 2000 OJ8 (magnitude 14), which happened to be in the field of view at the same time as the cloud of Elenin.
