Artist's impression of a preliminary design model of the European Space Agency's Giotto spacecraft as it flies within 500 kilometres of the nucleus of Halley's Comet on March 13,1986. The nucleus of the comet is portrayed,in line with current theories,as a giant "dirty snowball". As it plunges round the Sun,the outer layer vaporises to form the comet's bright tail of gas & dust. Halley's Comet returns every 76 years,and was last seen in 1910. The Giotto spacecraft was launched from Kourou,French Guiana,on July 2,1985 | |
