A supernova remnant 170,000 light years away in one of the Milky Way's galactic neighbours. This image, taken by the Hubble Space Telescope, shows ambient gas being shocked by the expanding blast wave from the exploding star.

Located approximately 300 million light-years away in the constellation of Volans, AM 0644-741 is one of the most spectacular ‘Ring Galaxies’ we currently know. - Image Credit: NASA, ESA, and The Hubble Heritage Team (AURA/STScI)
Celestial Finger Painting This colour-composite image was obtained by FORS1 on ANTU. It displays a sky area near the Chamaeleon I complex of bright nebulae and hot stars in the constellation of the same name, close to the southern celestial pole
The Cartwheel Galaxy is the result of two galaxies that collided about 700 million years ago. The outside ring is comprised of hot blue stars, formed from waves of density moving outwards following the collision. It's a bit larger than the Milky Way, and is located in the constellation Sculptor. It's about 500 million light years distant, or nearly 3 sextillion miles.
