The Tornado is an unusual radio source near the center of the Milky Way Galaxy showing a number of remarkable filamentary structures influenced by the magnetic field. It is thought to be a supernova remnant, although the evidence is still inconclusive. Another unusual source is a cluster of bright, compact nebulae located in the lower right edge of the Tornado Nebula. Astronomers debate the nature of the relationship between the larger Tornado Nebula and the cluster of compact nebulae.
Uranus is the third largest planet in our Solar System. Uranus has nine major rings and 27 known moons. This image, taken by the Hubble Space Telescope in infrared reveals cloud structures not normally visible. Methane gas in the upper atmosphere absorbs red light, giving the planet its blue-green color. Uranus is spinning on its side, probably because of a collision with a large object early in the Solar System's history.
