The Ison Comet

Postby Del » Tue Jan 01, 2013 3:17 pm

In 2013 a comet called Ison will put on a once in a lifetime show. The comet is expected to be visible to the naked eye for several months in late 2013, and could at times be brighter than the Moon.
It will be visible from all around the world.

OMG OMG OMG OMG OMG.... my father spent his whole life telling me HOW exciting it was for me to be on the planet when Halley's Comet came around (his lifetime actually worked so that he would miss it and it was one of his greatest regrets). It was the biggest fizzer of all time and I was devestated.

BUT THIS.............. OMG!

By the end of summer it will become visible in small telescopes and binoculars. By October it will pass close to Mars and things will begin to stir. The surface will shift as the ice responds to the thermal shock, cracks will appear in the crust, tiny puffs of gas will rise from it as it is warmed. The comet's tail is forming.

Slowly at first but with increasing vigour, as it passes the orbit of Earth, the gas and dust geysers will gather force. The space around the comet becomes brilliant as the ice below the surface turns into gas and erupts, reflecting the light of the Sun. Now Ison is surrounded by a cloud of gas called the coma, hundreds of thousands of miles from side to side. The comet's rotation curves these jets into space as they trail into spirals behind it. As they move out the gas trails are stopped and blown backwards by the Solar Wind.

By late November it will be visible to the unaided eye just after dark in the same direction as the setting Sun. Its tail could stretch like a searchlight into the sky above the horizon. Then it will swing rapidly around the Sun, passing within two million miles of it, far closer than any planet ever does, to emerge visible in the evening sky heading northward towards the pole star. It could be an "unaided eye" object for months. When it is close in its approach to the Sun it could become intensely brilliant but at that stage it would be difficult and dangerous to see without special instrumentation as it would be only a degree from the sun.

Remarkably Ison might not be the only spectacular comet visible next year. Another comet, called 2014 L4 (PanSTARRS), was discovered last year and in March and April it could also be a magnificent object in the evening sky. 2013 could be the year of the great comets.

Thanks for the heads up Del. I will be keeping an eye out for these and may try and borrow a telescope to get some photos. :D

When I walk the dig at night, I mostly look up; yes I've run into stuff doing that! :oops:

I'm really forward to this. It seems there has not been much to look at the last few years. Halley's Comet Hale Bopp were both very cool!
I did get the aurora borealis several times in Ottawa too. That's amazing to see. It does not happen here in NS though.

And it's true, we're fortunate to see these things in our lifetimes.

well it's logic Dug... It's when you don't draw them around your end AND NIGH... that you end up being a 'damnedable sinner'.

and a lot of fun that is too.... until someone loses an eye... or you get struck down with a flaming comet ......

Edit... I will have you know Bouncy .. I was the picture of ladinessness and vur ... vert ... verch ... damn I can't even spell it... purity and innocence til YOU and Meer came back!
