What happened to Comet Holmes? Just-released observations by NASA's Spitzer Space Telescope define the mass and velocity of the explosion: "The energy of the blast was about 1014 joules and the total mass was of order 1010 kg," says Bill Reach of Caltech. In other words, Holmes exploded like 24 kilotons of TNT and ejected 10 million metric tons of dust and gas into space. These numbers fit a model favored by Reach in which a cavern of ice some hundred meters beneath the comet's crust changed phase, from amorphous to crystalline, releasing in transition enough heat to cause Holmes to blow its top.

There was lots of speculation about why this comet exploded, but it looks like we know why now. I also seem to recall there were some predictions that there was going to be a second outburst, but that never happened. It seems like we still have much to learn about these enigmatic objects.

The following is my opinion as a member participating in this discussion.


I had my money on that Comet Holmes brightened due to a collision with a rogue asteroid, but as many suspected, it was just a collapse of a cavern. I find it amazing that they could estimate the energy release before hand and have it match actual measurements. Kudos to NASA.

hehehehe

sorry can't stop..

a cavern..
an ice cavern changes phase??
exploding ice
wait till the chinese hear about this..
we could drop antartica on them..

yes an exploding ICE cavern.

theyre may well be more outbustrs.. a good idea would to watch in and around planetary alignments..



sorry in all seriousness..

i can't do this anymore
