Uranus is the seventh planet from the Sun. It is named after Greek sky deity Uranus (Caelus), who in Greek mythology is the father of Cronus (Saturn), a grandfather of Zeus (Jupiter) and great-grandfather of Ares (Mars). Uranus has the third-largest planetary radius and fourth-largest planetary mass in the Solar System. The planet is similar in composition to Neptune, and both have bulk chemical compositions which differ from those of the other two giant planets, Jupiter and Saturn (the gas giants). For this reason, scientists often distinguish Uranus and Neptune as “ice giants“.
As with gas giants, ice giants lack a well-defined solid surface. Uranus’s atmosphere is similar to Jupiter’s and Saturn’s in its primary composition of hydrogen and helium, but it contains more “ices” such as water, ammonia, and methane, along with traces of other hydrocarbons. It has the coldest planetary atmosphere in the Solar System, with a minimum temperature of 49 kelvins (−224 °C; −371 °F). It has a complex, layered cloud structure; water is thought to make up the lowest clouds and methane the uppermost layer. The planet’s interior is mainly composed of ices and rock.
Like the other giant planets, Uranus has a ring system, a magnetosphere, and numerous moons. The Uranian system has a unique configuration because its axis of rotation is tilted sideways, nearly into the plane of its solar orbit. Therefore, its north and south poles lie where most other planets have their equators. In 1986, images from Voyager 2 showed Uranus as an almost featureless planet in visible light, without the cloud bands or storms associated with the other giant planets. No other spacecraft has yet visited the planet. Observations from Earth have shown seasonal change and increased weather activity as Uranus approached its equinox in 2007. Wind speeds can reach 250 metres per second (900 km/h; 560 mph).

Frederick William Herschel KH, FRS (/ˈhɜːrʃəl, ˈhɛər-/; German: Friedrich Wilhelm Herschel; 15 November 1738 – 25 August 1822) was a German-born British astronomer and composer. He frequently collaborated with his younger sister and fellow astronomer Caroline Herschel (1750–1848). Born in the Electorate of Hanover, William Herschel followed his father into the military band of Hanover, before emigrating to Great Britain in 1757 at the age of nineteen.
Herschel constructed his first large telescope in 1774, after which he spent nine years carrying out sky surveys to investigate double stars. Herschel published catalogues of nebulae in 1802 (2,500 objects) and in 1820 (5,000 objects). The resolving power of the Herschel telescopes revealed that many objects called nebulae in the Messier catalogue were actually clusters of stars. On 13 March 1781 while making observations he made note of a new object in the constellation of Gemini. This would, after several weeks of verification and consultation with other astronomers, be confirmed to be a new planet, eventually given the name of Uranus. This was the first planet to be discovered since antiquity, and Herschel became famous overnight. As a result of this discovery, George III appointed him Court Astronomer. He was elected a Fellow of the Royal Society and grants were provided for the construction of new telescopes.
Herschel pioneered the use of astronomical spectrophotometry, using prisms and temperature measuring equipment to measure the wavelength distribution of stellar spectra. In the course of these investigations, Herschel discovered infrared radiation. Other work included an improved determination of the rotation period of Mars, the discovery that the Martian polar caps vary seasonally, the discovery of Titania and Oberon (moons of Uranus) and Enceladus and Mimas (moons of Saturn). Herschel was made a Knight of the Royal Guelphic Order in 1816. He was the first President of the Royal Astronomical Society when it was founded in 1820. He died in August 1822, and his work was continued by his only son, John Herschel.
A day for the 53 Commonwealth countries to acknowledge their shared values, their diversity, and their combined contributions to international harmony and prosperity. Since 1977, this day of observance occurs in Canada on the second Monday in March. The Royal Union flag is flown at many federal locations, and students learn about the Commonwealth via special activities.
Question of the Day
Does Vermont have a long enough growing season for red peppers? The green bell type are no problem. How about okra?
It is possible to grow red bell peppers in Vermont (and areas with a similar climate), but they may not be as large as their southern-grown cousins. If they’re planted in a sheltered valley, if spring comes early, and if the summer is hot, hot, hot—then maybe. Okra, on the other hand, is better suited to warmer climates. This plant requires a warm soil and climate, which is why it is associated with the South!
Advice of the Day
Though honey is sweet, do not lick it off a brier.
Home Hint of the Day
When laying a floor, start along the most irregular wall. It’s easier to cut for that wall before laying floorboards that close you in.
Word of the Day
The visible rising and setting of the Sun’s upper limb across the unobstructed horizon of an observer whose eyes are 15 feet above ground level.
