Uranus is the seventh planet from the Sun. It is a gaseous cyan -coloured ice giant. Most of the planet is made of water, ammonia, and methane in a supercritical phase of matter, which in astronomy is called 'ice' or volatiles. The planet's atmosphere has a complex layered cloud structure and has the lowest minimum temperature of 49 K (−224 ...
Uranus is an unusual world that spins on its side with a 98-degree tilt, which means the icy planet experiences seasons in an extreme way. One year on Uranus lasts around 84 Earth years, and for ...
The rings of Uranus were discovered on March 10, 1977, by James L. Elliot, Edward W. Dunham, and Jessica Mink. William Herschel had also reported observing rings in 1789; modern astronomers are divided on whether he could have seen them, as they are very dark and faint. [1] By 1977, nine distinct rings were identified.
Uranus was the last giant planet without any known irregular moons until 1997, when astronomers using ground-based telescopes discovered Sycorax and Caliban. From 1999 to 2003, astronomers continued searching for irregular moons of Uranus using more powerful ground-based telescopes, resulting in the discovery of seven more Uranian irregular moons.
NASA released new images Monday that show Uranus, the seventh planet from the sun, in greater detail than ever before. The new images of Uranus were captured by the James Webb Space Telescope and ...
The climate of Uranus is heavily influenced by both its lack of internal heat, which limits atmospheric activity, and by its extreme axial tilt, which induces intense seasonal variation. Uranus's atmosphere is remarkably bland in comparison to the other giant planets which it otherwise closely resembles. [1] [2] When Voyager 2 flew by Uranus in ...
NEPTUNE is the world's first regional-scale underwater ocean observatory that plugs directly into the Internet. [1] NEPTUNE is the largest installation on the Ocean Networks Canada network of ocean observatories. Since December 2009, it has allowed people to "surf" the seafloor while ocean scientists run deep-water experiments from labs and ...
Mercury is the first planet from the Sun and the smallest in the Solar System. In English, it is named after the ancient Roman god Mercurius ( Mercury ), god of commerce and communication, and the messenger of the gods. Mercury is classified as a terrestrial planet, with roughly the same surface gravity as Mars.
