The much anticipated
Comet ISON is expected to put on a spectacular show as it makes it's extremely close approach to the sun on
Thanksgiving day, November 28, 2013. From now until then,
ISON is expected to increase in brightness and then fade into the suns glare as it makes its way in. Right now, the comet can be seen as a faint blob of light above the horizon, in the south to south east portion of the early morning sky, at about a half an hour before sunrise.
The comet,
C/2012 S1, was discovered by two amateur astronomers,
Vitali Nevski and
Artyom Novichonok, after observing photographs taken by an
ISON telescope in September 2012.
ISON stands for
International Scientific Optical Network and was established as a Russian initiative to monitor and study near Earth objects and space debris in 2001. In the year since its discovery, comet
C/2012 S1 was given the name
ISON.
Right now, as
ISON gets closer to the sun, its getting brighter and brighter.
ISON is expected to pass within
730,000 miles of the sun on
Thanksgiving day. At that distance, it is possible that the comet may actually break up and fall into the sun.
If
ISON survives its rendezvous with ole Sol, scientists say that it will appear as a very bright comet in the skies of the northern hemisphere. They also believe that the comet will pass in front of the sun as it moves back out into the solar system, and as it dose they may see extreme emissions of ultraviolet radiation. It's said that if
ISON survives, it may even become visible during daylight hours.
ISON is expected to be visible with the naked eye through the month of
December, including
Christmas Eve and
Christmas night. Have no fear though.
ISON will pose no threat to the Earth. At its closest approach it will still be
40 million miles away, which is a little less than half of the distance between the Earth and the sun.
