Comet Lovejoy Survives Fiery Plunge Through Sun, NASA Says
Space.com via Yahoo News ^ | 16 Dec 2011 | Mike Wall

A newfound comet defied long odds on Thursday (Dec. 15), surviving a suicidal dive through the sun's hellishly hot atmosphere, according to NASA scientists.

Comet Lovejoy plunged through the sun's corona at about 7 p.m. EST (midnight GMT on Dec. 16), coming within 87,000 miles (140,000 kilometers) of our star's surface. Temperatures in the corona can reach 2 million degrees Fahrenheit (1.1 million degrees Celsius), so most researchers expected the icy wanderer to be completely destroyed.

But Lovejoy proved to be made of tough stuff. A video taken by NASA's Solar Dynamics Observatory (SDO) spacecraft showed the icy object emerging from behind the sun and zipping back off into space.

Lovejoy conquers all.

I guess the “snowball’s chance in hell” expression has lost some of it’s former luster.

If the comet survived, I’m pretty sure it didn’t go “through” the sun.

While wickedly “hot”, the corona’s density is too light to transmit heat to such a large mass.

Headline is a bit misleading. It went through the outer portion, the corona, supposedly. Then again, they may be wrong about that as well.

A popular scientific dictum about space climate was wrong? Wait for the emails to be leaked!!

I wonder now, what is it that is left, after passing so close to the surface of the sun? Also, how was it's trajectory affected? Pretty amazing stuff.

Here's a cool video I found this morning:

The comet must have taken some of those fire walking classes.

Lovejoy did some time in the nick if I remember right so he had to be tough and conquer plus make a few quid on art..

I'll bet it wasn't as tough as this Lovejoy ...

Yep, I think “corona” got chopped out of that sentence.

Comet Lovejoy plunged through the sun's corona at about 7 p.m. EST (midnight GMT on Dec. 16). . . .

Well, that's it. The comet went at night and in mid-December. Naturally it's going to be cooler.

I guess it probably ablatively shielded itself. This is way cool!

Exactly. It didn’t set the controls for the heart of the sun: http://www.youtube.com/watch?v=AtIBZNl3DY4

Maybe... just maybe it wasn't made of ice?

I actually had to think about that for a few seconds.

Also, how was it's trajectory affected?

The basic elliptical trajectory wouldn't be affected at all by the sun's gravity, that's what it is all about. The atmospheric drag and solar wind should cause a noticable effect. Comet Lovejoy is a member of a class of comets called Kreutz sungrazers. They are the remants of an 11th Century comet that was broken up by tidal forces when it passed too close to the sun. The solar corona is about a trillion trillion times less dense than the earth's atmosphere at sea level, btw.

It didn't survive because the sun is cooler than they thought but because Lovejoy is bigger than expected. It will not survive many such approaches.
