Comet Hyakutake

These images of Comet Hyakutake focus on a very small region near the heart of the comet -- the icy, solid nucleus. The icy regions of the nucleus are activated as they rotate into sunlight, ejecting large amounts of dust in the jets that are faintly visible here. Sunlight striking this dust eventually turns it around and "blows" it into the tailward hemisphere.

Dear Grandma and Uncle Jim,

Thank you for the presents.

From Lilly
