A Unique Hubble View of Comet ISON
Credit: NASA, ESA, and the Hubble Heritage Team (STScI/AURA)
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. In this composite image, background stars and galaxies were separately photographed in red and yellow-green light. 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. The images were taken with the Wide Field Camera 3 on April 30, 2013.

Comet ISON on Sept. 15, 2013
Credit: P. Lawrence
UK astronomer Pete Lawrence took this image of Comet ISON in the early hours of Sept. 15, 2013, using a Vixen FL-102S 10 cm APO telescope and a Starlight Express SXV-H9 CCD camera. The camera was exposed for a total time of 40 minutes, comprising 10 x 120 s exposures and 4 x 300 s exposures, with the images stacked together to produce the final result. The streaks in the background are star trails, the apparent motion of stars in the night sky due to the rotation of Earth. North is in the direction of a line drawn from the comet's head towards the upper-left corner of the image.

Comet ISON Photos by Spitzer Space Telescope
Credit: NASA/JPL-Caltech/JHUAPL/UCF
These images from NASA's Spitzer Space Telescope of Comet ISON were taken on June 13, 2013, when ISON was 312 million miles (502 million kilometers) from the sun. The lefthand image shows a tail of fine rocky dust issuing from the comet, blown back by the pressure of sunlight. The image at right shows a neutral gas atmosphere surrounding ISON, likely created by carbon dioxide fizzing off the comet at a rate of 2.2 million pounds per day. []

SWIFT Satellite Sees Comet ISON
Credit: NASA/Swift/D. Bodewits, UMCP
The Ultraviolet/Optical Telescope aboard NASA's Swift imaged comet ISON (center) on Jan. 30, when it was located about 3.3 degrees from the bright star Castor in the constellation Gemini. At the time of this 5.5-minute optical exposure, ISON was about 5,000 times fainter than the limit of human vision. Image released March 29, 2013.

Orbital Trajectory of Comet C/2012 S1 (ISON)
Credit: NASA/JPL-Caltech
This is the orbital trajectory of comet C/2012 S1 (ISON). The comet is currently located just inside the orbit of Jupiter. In November 2013, ISON will pass less than 1.1 million miles (1.8 million kilometers) from the sun's surface. The fierce heating it experiences during this close approach to the sun could turn the comet into a bright naked-eye object. Image released Feb. 5, 2013. [Read the full story]
