July 4, NASA's Deep Impact
spacecraft will attempt an extraordinarily daring encounter with the far

comet Tempel 1 hurtling through space at tens of thousands of miles per hour.
When viewing
a comet in visible light from very far away, only reflected
sunlight can be seen, so a big, dark
comet can look the same as a highly
reflective, small comet. "Like photographers, it's important
for us to know our subject before

moons with companion Trojan moons. If Pan's orbit remains
eccentric due to this interaction, then
planets growing in a disc of material surrounding a star

eccentric orbits. Some
lie in various gaps in the rings and may indicate the presence
of tiny
embedded moons acting as shepherds.

Another discovery was a tiny moon, about three miles across, recently

indicates the type of interaction the
moon has with the ring material
surrounding it. "This may have important consequences for the
identification
