a small telescope or a featureless large orb in a large telescope. Last August, however, the Hubble Space Telescope was able to photograph Uranus in infrared light, where the distant planet better shows its unusual clouds, rings, and moons. Recent analysis indicates that clouds seen here in orange appear to circle Uranus at speeds in excess of 500 kilometers per hour. Comparisons to earlier photographs show a slight precession shift in the brightest of Uranus' rings. Several of Uranus' numerous small moons are visible.UMA REPRODUCAO DO TELESCOPIOUSADO PARA DESCOBRIR URANO- Na casa de WILLIAM HERSCHELA reproduction of the telescope used to discover Uranus, Herschel House, Bath, England, // Credit: David J.

Aos 19 anos mudou-se para a Inglaterra onde passou a ensinar musica, antes de se tornar um organista. Com o tempo passou a estudar astronomia e ficou famoso por sua descoberta do planeta Urano, assim como de duas de suas luas (Titania e Oberon), ele tambem descobriu duas luas de Saturno e a existencia da radiacao infravermelha.

Uranus is composed mostly of rock and ices, but with a thick hydrogen and helium atmosphere. The blue hue of Uranus' atmosphere arises from the small amount of methane which preferentially absorbs red light. This picture was snapped by the Voyager 2 spacecraft in 1986 - the only spacecraft ever to visit Uranus. Uranus has many moons and a ring system. Uranus, like Venus, has a rotation axis that is greatly tilted and sometimes points near the Sun. It remains an astronomical mystery why Uranus' axis is so tilted. Uranus and Neptune are quite similar: Uranus is slightly larger but less massive.LEIA SOBRE URANOacessandohttp://www.nasa.gov/pdf/62231main_Uranus.Lithograph.pdfSignificant Dates1781: Astronomer William Herschel discovers Uranus.1787-1851: Four Uranian moons are discovered and named Titania, Oberon, Ariel, and Umbriel.1948: Another moon, Miranda, is discovered.1977: Scientists discover nine faint rings of Uranus while observing a distant star pass behind the planet.1986: Voyager 2 discovers 10 moons and two additional rings during its historic flyby.1997-2005: Astronomers discover more tiny moons.2003-2005: The Hubble Space Telescope images two delicate rings far from the planet and two new moons.2007: Uranus reaches equinox.http://solarsystem.nasa.gov/planets/profile.cfm?Object=Uranus&Display=OverviewLongDatas Significativas1781 - O astronomo William Herschel descobre Urano.1787-1851: Quatro Luas
