Saturn from Earth

Saturn is the second largest planet in our Solar System. Saturn has been easily visible in the sky since history has been recorded. Galileo used one of the first telescopes in 1610 to discover Saturn's rings, which he first thought were moons. Maxwell showed in 1856 that Saturn's rings couldn't be a single solid, since Saturn's own gravity would break it up. Were Saturn's rings assembled into a single body, it would measure less than 100 kilometers across. The origin of Saturn's rings, and of unusual radial patterns that appear on them called spokes, are still unknown. The above representative-color picture was taken from Earth in infrared light. A robot spacecraft Cassini launched in 1997 will reach Saturn in 2004.

Local Group Galaxy NGC 205

The Milky Way Galaxy is not alone. It is part of a gathering of about 25 galaxies known as the Local Group. Members include the Great Andromeda Galaxy (M31), M32, M33, the Large Magellanic Clouds, the Small Magellanic Clouds, Dwingeloo 1, several small irregular galaxies, and many dwarf elliptical galaxies. Pictured is one of the many dwarf ellipticals: NGC 205. Like M32, NGC 205 is a companion to the large M31, and can sometimes be seen to the south of M31's center in photographs. The above image shows this galaxy to be unusual for an elliptical galaxy in that it contains at least two dust clouds (at 7 and 11 o'clock - they are visible but hard to spot) and signs of recent star formation. This galaxy is sometimes known as M110, although it was actually not part of Messier's original catalog.

Hideaway

Is this a picture of a sunset from Earth's North Pole? Regardless of urban legends circulating the Internet, the answer is no. The above scene was drawn to be an imaginary celestial place that would be calm and peaceful, and therefore titled Hideaway. The scene could not exist anywhere on the Earth because from the Earth, the Moon and the Sun always have nearly the same angular size. This is particularly apparent, for example, during solar eclipses. Still, the scene drawn is quite striking, and the crescent part of the "moon" shown is approximately accurate given the location of the parent star. In reality, the North Pole of Earth looks different. Starting earlier this month, the North Pole even has a web camera returning near-live pictures.
