The Nucleus of Comet Halley
Giotto's encounter with Comet Halley provided the first ever opportunity to take images of a comet nucleus. The images were obtained with the Halley Multicolour Camera on Giotto.

Summary
Giotto was ESA's first deep space mission, part of an ambitious international effort to solve the mysteries surrounding Comet Halley.
Fact Sheet
ESA's first deep space mission, Giotto was designed to help solve the mysteries surrounding Comet Halley by passing as close as possible to the comet's nucleus, which it achieved on 13 March 1986. ...
