Latest News – 2nd December: NASA are currently investigating what (if anything) is left of Comet ISON. If it has survived, there’s no doubt that it’s certainly not the comet it once was. It is yet to be established however if the flare like appearance of Comet ISON, seen in the images as it sped away from the Sun, were just a result of dust burning up or if the comet still has a small nucleus. The Hubble Space Telescope is due to make further observations in the coming weeks.
Starting at around 95,000mph at the start of the month, Comet ISON will eventually reach an astonishing 845,000mph on November 28th when it catapults round the Sun at perihelion! Check out our LIVE Distance and Speed page.
Comet ISON was discovered on September 21st 2012 by Vitali Nevski and Artyom Novichonok, two Russian Astronomers of the ‘International Scientific Optical Network’. At the time of discovery, ISON was over 584 million miles (6.29 AU) from the Sun.
Indications from students processing data from NASA’s Swift satellite, estimate Comet ISON’s size to be around 3 miles in diameter. They have reached this conclusion by observing the amount of ice and dust emitted from ISON’s surface as it falls through space toward the Sun.

As Comet ISON speeds towards perihelion, NASA’s Solar TErrestrial RElations Observatory probes (also known as STEREO) have captured the sungrazer comet in a series of images taken from the far side of the Sun.
Shown here in an animated sequence, we can clearly see Comet ISON battling its way through the solar wind between November 20th and 25th …more >
