Comet ISON — New Image Of Rapidly Approaching Comet Taken By Hubble - PlanetSave.com Jul 27th 2013, 23:02
Comet ISON — the rapidly approaching 'comet of the century', as some have dubbed it — is the subject of a spectacular newly released image. In the image, the the icy comet is seen against a stellar backdrop which includes a number of stars and galaxies.
"In this Hubble Space Telescope composite image taken in April 2013, the sun-approaching Comet ISON floats against a seemingly infinite backdrop of numerous galaxies and a handful of foreground stars. The icy visitor, with its long gossamer tail, appears to be swimming like a tadpole through a deep pond of celestial wonders. The background stars and galaxies were separately photographed in red and yellow-green light with the Wide Field Camera 3. Because the comet moved between exposures relative to the background objects, its appearance was blurred. The blurred comet photo was replaced with a single, black-and-white exposure. This photo is one of the original images featured on ISONblog, a new online source offering unique analysis of Comet ISON by Hubble Space Telescope astronomers and staff at the Space Telescope Science Institute in Baltimore, Md."

The image, which was taken by the Hubble Space Telescope, is actually a composite image — background stars and galaxies were imaged separately in red and yellow-green light. As the comet moved some between exposures, in relation to the stars and galaxies objects, the appearance of the comet was blurred — so the blurred comet image was replaced with a single, black-and-white exposure.
Comet ISON has been increasing in brightness fairly steadily since its discovery — as you can see in these images here.
"Comet ISON is predicted to likely put on quite a show later this year — in late November the comet could possibly become as bright as the Full Moon, and even visible in broad daylight, according to some sources. Of course, comets are notoriously hard to predict, so we'll have to wait and see with regards to the predictions."
