Deep Impact-Cam
The last footage from the Deep Impact probe July 4, 2005. Comets are theorised to be mostly made of water ice. Impacts in the past may have given Earth its water. If large asteroids like Ceres turn out to contain water, they may also have contributed.

I really appreciate that you share the lesser publicized stuff here. Thanks!
Thank you, it is my pleasure when people enjoy these posts. As the movie DEEP IMPACT depicted, research on comets and asteroids can literally save the world.
I've always thought that one of the odd features of iron meteorites is how well differentiated and crystallized they are. The high degree of differentiation just doesn't seem to stack up well with the theory that they were from matter that didn't consolidate into a very large body.
To get the excellent differentiation requires a strong gravitational field. To get the excellent crystallization implies that they were very hot for very long times and only cooled very slowly.
But if they are associated with singularities, both the excelleng crystallization and the good diferentiation are well explained.
HI Carl. I recently bought another meteorite from a collector. They make good paperweights and are fascinating to study! He also said the idea of "radioactive decay" is nonsense.
