Shoemaker-Levy 9: This Hubble Space Telescope image shows the P-Q complex, also called the "gang of four' region, of Comet P/Shoemaker-Levy 9. It was taken on 17 May 1994 with the WFPC2 (in “wide field” mode).

The Spiral Galaxy M 100: An image of the grand design spiral galaxy Messier 100 obtained with the Hubble Space Telescope resolves individual stars within the majestic spiral arms. Messier 100 (100th object in the Messier catalog of non-stellar objects) is a face-on spiral galaxy.  It is a rotating system of gas and stars, similar to our own galaxy, the Milky Way. Hubble routinely can view M100 with a level of clarity and sensitivity previously possible only for very few nearby galaxies. M100 is a member of the huge Virgo cluster of an estimated 2,500 galaxies.  The galaxy can be seen by amateur astronomers as a faint, pinwheel-shaped object in the spring constellation Coma Berenices. An image of the grand design of spiral galaxy M100 obtained with the Hubble Space Telescope resolves individual stars within the majestic spiral arms. (These stars typically appeared blurred together when viewed with ground-based telescopes).

Cepheid Variable Star in Galaxy M100: This NASA/ESA Hubble Space Telescope image of a region of the galaxy M100 shows a class of pulsating star called a Cepheid Variable. Though rare, these stars are reliable distance indicators to galaxies. Based on the Hubble observation, the distance to M100 has been measured accurately as 56 million light-years (+/- 6 million light-years), making it the farthest object where intergalactic distances have been determined precisely.

Surface of Titan: Scientists for the first time have made images of the surface of Saturn's giant, haze-shrouded moon, Titan. They mapped light and dark features over the surface of the satellite during nearly a complete 16-day rotation. One prominent bright area they discovered is a surface feature 2, 500 miles across (about 4025 kilometres), about the size of the continent of Australia.

The Cat's Eye Nebula: This Hubble Space Telescope image shows one of the most complex planetary nebulae ever seen, NGC 6543, nicknamed the 'Cat's Eye Nebula.' Hubble reveals surprisingly intricate structures including concentric gas shells, jets of high-speed gas and unusual shock-induced knots of gas. Estimated to be 1, 000 years old, the nebula is a visual 'fossil record' of the dynamics and late evolution of a dying star.

The Cartwheel Galaxy: A rare and spectacular head-on collision between two galaxies appears in this Hubble Space Telescope true-color image of the Cartwheel Galaxy, located 500 million light-years away in the constellation Sculptor. The new details of star birth resolved by Hubble provide an opportunity to study how extremely massive stars are born in large fragmented gas clouds.
