Hubble Probes Inner Region of Comet Hyakutake

Explanation: These are NASA Hubble Space Telescope images of the long-period comet Hyakutake (designated C/1996 B2), taken at 8:30 P.M., EST on Monday, March 25 when the comet passed at a distance of only 9.3 million miles from Earth. Unlike most other images of Hyakutake, these Hubble images focus on a very small region near the heart of the comet, the icy, solid nucleus.
