Comet ISON is every day more and more closer to the Sun, and with every new day it reveals more new details. More astronomers report clearly visible double tail feature. Primary ion gas tail developed a dust tail companion so now Comet ISON is double tail
Comet ISON has almost completed its journey from the Oort Cloud to Sun's photosphere and is now inside the orbit of Earth. On November 28, 2013 Comet ISON will fly only 1 million kilometers (2.7 solar radii) above Sun's surface,

T -0 D-day! Comet ISON vs The Sun
Most of you have already seen latest ISON images from SOHO's LASCO and are sharing this unique experience with the rest of the world. If you are not in the train yet… we are all watching ISON via
After several weeks of being hidden behind the Sun, comet C/2012 S1 (ISON) finally emerged from solar conjunction mid August, and early, tentative measures of its brightness by CIOC hint that it is beginning to slowly brighten up.
CIOC writes: From
Sungrazing comets are a special class of comets that come very close to the Sun at their nearest approach, a point called perihelion. To be considered a sungrazer, a comet needs to get within about 850,000 miles from the sun at perihelion. Many come even closer, even
Spitzer Space Telescope observed Comet ISON for 24 hours period on June 13, 2013. Its processed imagery indicate that carbon dioxide and dust are spewing out of the comet at high rate. At the time, Comet ISON was about 312 million miles (502 million
Enhanced image of comet C/2012 S1 ISON obtained by Hubble Space Telescope on April 30, 2013 have been released yesterday, showing the comet zooming through deep space in all its glory.

Comet C/2012 S1 ISON is currently flying towards the Sun at a mind boggling speed of about 77 000 km/h (48 000 mph). Recently NASA released a time-lapse movie of the eagerly awaited comet. The movie is composed of images obtained by Hubble Space
Experts all over the planet are eagerly tracking Comet ISON (C/2012 S1), the so called "Comet of the century". However since June 22, 2013 the comet is so near to the Sun, less than 18 degrees, making it not visible against the dark sky. The comet will
Comet ISON is expected to become one of the most dazzling skywatching events while making a passage around the Sun later this year. In October of 2012 NASA's Jet Propulsion Laboratory (JPL) stated that Comet ISON (C/2012 S1) could reach magnitude -11.6, which
