uranus

Uranus is the seventh planet from the Sun. It has the third-largest planetary radius and fourth-largest planetary mass in the Solar System. Uranus is similar in composition to Neptune, and both are of different chemical composition than the larger gas giants Jupiter and Saturn. For this reason, astronomers sometimes place them in a separate category called "ice giants". Uranus's atmosphere, although similar to Jupiter's and Saturn's in its primary composition of hydrogen and helium, contains more "ices" such as water, ammonia, and methane, along with traces of hydrocarbons.[12] It is the coldest planetary atmosphere in the Solar System, with a minimum temperature of 49 K (−224 Â°C). It has a complex, layered cloud structure, with water thought to make up the lowest clouds, and methane thought to make up the uppermost layer of clouds.[12] In contrast, the interior of Uranus is mainly composed of ices and rock.[11]

Most detailed observations of Uranus reveal complex atmospheric patterns

Fri, Oct 19, 2012

The most detailed observations of the icy world of Uranus, the seventh planet from the sun, show complex weather patterns and other features that scientists have yet to fully describe. Popular belief had Uranus depicted as a bland, pale green world based on the now iconic observations from Voyager’s 1986 flyby of the planet. Its [...]

Astronomers luckily spot Aurora on Uranus

Sat, Apr 14, 2012

When Voyager 2 made its flyby near the planet of Uranus, astronomers got their first direct glimpse of what an aurora might look on the cold planet. However, such lights have never been observed from Earth – that is, until last year, when a team of scientists used careful planning and the Hubble Telescope to [...]

Uranus orbit tipped on its side by a series of Earth-sized impacts

Uranus, the seventh planet from the sun, is a definite oddball of the solar system. It has its axis titled by a whopping 98 degrees, which makes it orbit on its side. The general accepted theory is that a big impact with an object several times the size that of the Earth nodged its axis [...]

Probe launched 30 years ago is held back by mysterious unexplained force

A probe that has been launched no less than 30 years ago has come across a force that has baffled the scientific world and could rewrite the laws of physics. In 1983, Pioneer 10 took some photos of Jupiter, then left the solar system. However, it’s being pulled back to the Sun by a force [...]

Oceans of diamonds on Uranus

Sat, Jan 23, 2010

1 Comment

A new research published in Nature Physics showed that there may be oceans of diamonds (literally) on both Uranus and Neptune. The first ever study conducted on the melting point of diamond concluded that at that certain point, it behaves just like water, with the solid form floating in the liquid form (just imagine icebergs, [...]
