NASA astronomers have captured an amazing new photo of the brightening Comet ISON, an image that reveals the comet's intricate tail as it heads for a rendezvous with the sun next week.
The new photo of Comet ISON was taken Tuesday (Nov. 19) by scientists at NASA's Marshall Space Flight Center in Huntsville, Ala., nine days ahead of the comet's Thanksgiving Day close encounter with the sun on Nov. 28.
"Comet ISON shows off its tail …" NASA's image description begins. The comet photo was taken early Tuesday at 6:10 a.m. EST (1110 GMT) by Aaron Kingery at the Marshall center. He used a 14-inch telescope with a three-minute exposure time, according to the image description. [Comet ISON's Stargazing Show : 8 Essential Facts]
"The comet is just nine days away from its close encounter with the sun; hopefully it will survive to put on a nice show during the first week of December," NASA officials wrote of the image. "The star images are trailed because the telescope is tracking on the comet, which is now exhibiting obvious motion with respect to the background stars over a period of minutes."
Comet ISON was first discovered by Russian amateur astronomers Vitali Nevski and Artyom Novichonok in September 2012 with a remotely operated telescope in the International Scientific Optical Network (ISON). The comet is officially designated as C/2012 S1 (ISON).
On Nov. 28, Comet ISON will make its closest approach to the sun and come within 730,000 miles (1.2 million kilometers) of the solar surface. The comet has drawn much attention from the public, stargazers and professional astronomers because of hopes that it might flare up into a so-called "comet of the century" after its sun flyby.
While Comet ISON did not brighten as predicted, the comet did undergo a surprise outburst last week to become visible to the naked eye in the southeastern pre-dawn sky. The comet is more clearly visible in binoculars and telescopes, and can be found low in the the east-southeastern sky about one hour before sunrise.
The major uncertainty with Comet ISON is whether it will survive its encounter with the sun, or if it will break apart and be destroyed. Scientists aren't yet sure which path the comet's evolution will take.
