NASA Mars Picture of the Day:
Mars Global Surveyor Mars Orbiter Camera
MGS MOC Release No. MOC2-1480
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows windblown ripples on the floor of Auqakuh Vallis. The light-toned area, running diagonally across the scene from the lower left (southwest) to the upper right (northeast), may be dust that has accumulated in the bottom of the valley and on top of the ripples.
Location near: 31.3° N / 299.3°W
Image width: ~3 km (~1.9 mi)
Illumination from lower left
Northern [hemisphere] Spring
Malin Space Science Systems and the California Institute of Technology built the MOC using spare hardware from the Mars Observer mission. MSSS operates the camera from its facilities in San Diego, California. The Jet Propulsion Laboratory's Mars Surveyor Operations Project operates the Mars Global Surveyor spacecraft with its industrial partner, Lockheed Martin Astronautics, from facilities in Pasadena, California and Denver, Colorado.

ah shit, here's another ad from this site. Also Caveat Emptor ... but this one's for a big price range of all sorts of amateur telescopes.
Vleeptron ain't making any $ for these ads. But jeez ... will you or your kids suffer from looking at the night skies with a good telescope? How bad will you regret it if you let yourself get sucked into buying a good telescope?
If you get the reflecting kind that focuses everything through a parabolic mirror, Isaac Newton invented that one. I think you can still see the first one he built with his own hands and presented to the Royal Society. From the BBC's bio:
It was Newton's reflecting telescope, made in 1668, that finally brought him into full view of the scientific community. His work with colours led him to believe that refracting telescopes [a Dutch invention improved by Galileo], which were subject to colour interference, were outdated. He made his reflecting telescope entirely on his own, some parts of it with tools that he made specifically for the purpose. His invention made telescopes much smaller - his was only six inches long, and one inch in diameter, yet it magnified over 30 times.
It was especially useful when looking at distant bodies such as Jupiter, which only reflected small amounts of light, and to this day, the most powerful telescopes continue to use reflecting dishes according to Newton's principle. Newton was so proud of his telescope, that he couldn't resist showing it off. Word went around Cambridge, and then the Royal Society got wind of the invention, and asked to see it. When the telescope arrived, it caused a sensation. Newton was ecstatic, despite his pretence of indifference, and in return sent them his theory of colours in a letter.
The letter Newton sent contained nothing new, but it was the first time that his work had been made available for discussion by other scientists. Robert Hooke, a leading power at the Royal Society, however, considered optics to be his domain, and he refuted much of what Newton said. This critique of Newton's work was to be the beginning of a long and spiteful rivalry between the two men, with Newton taking an arrogant stance, and Hooke often accusing Newton of plagiarism. Newton also received some criticism of his optics experiments from some Jesuits, who claimed that they could not replicate Newton's prism experiment, and therefore it was wrong. Newton erupted in anger at this, and at Hooke. He convinced himself of a conspiracy against him, and gave up the study of optics, refusing to correspond with anyone about it.
