Comet ISON Expected To Impact The Sun On 28 November 2013 -

Comet ISON expected to impact the sun
around 28 November 2013, which could
have catastrophic consequences of
biblical proportions.

A comet’s journey through the solar
system is perilous and violent. A
giant ejection of solar material from
the sun could rip its tail off. Before it
reaches Mars -- at some 230 million
miles away from the sun -- the
radiation of the sun begins to boil its
water, the first step toward breaking
apart. And, if it survives all this, the
intense radiation and pressure as it
flies near the surface of the sun
could destroy it altogether.

Right now, Comet ISON is making
that journey. It began its trip from
the Oort cloud region of our solar
system and is now travelling toward
the sun. The comet will reach its
closest approach to the sun on
Thanksgiving Day -- Nov. 28, 2013 --
skimming just 730,000 miles above
the sun’s surface. If it comes around
the sun without breaking up, the
comet will be visible in the Northern
Hemisphere with the Unclad eye, and
from what we see now, ISON is
predicted to be a particularly bright
and beautiful comet.
Cataloged as C/2012 S1, Comet ISON
was first spotted 585 million miles
away in September 2012. This is its
very first trip around the sun, which
means it is still made of pristine
matter from the earliest days of the
solar system’s formation, its top
layers never having been lost by a
trip near the sun. Scientists will point
as many ground-based observatories
as they can and at least 15 space-
based assets towards the comet
along the way, in order to learn
more about this time capsule from
when the solar system first formed.
Even if the comet does not survive,
tracking its journey will help
scientists understand what the comet
is made of, how it reacts to its
environment, and what this explains
about the origins of the solar system.
Closer to the sun, watching how the
comet and its tail interact with the
vast solar atmosphere can teach
scientists more about the sun itself.
