Comet 67P's heavy water

Post by brian livesey »

Recent data from Rosseta shows that the water on Comet 67 is three times heavier than Earth's water. Does that make it beer?
Seriously, if 67P's water is that heavy and the comet is typical, it adds to the mystery of where most of Earth's water came from, if not from comets.

Hi Brian L.,

Can you post the link to the info. that says comet 67P's water is 3 times heavier than regular water? 3 times seems a lot.

I'm not quite sure about the beer reference; I know that when picking up a pint of beer it is not noticeably heavier than picking up a pint of water :wink:

Best Wishes,

Geoff :)

It got a mention on Radio Four's regular Thursday evening science programme last week. Also, see the current issue of "New Scientist".
