  Umbriel (moon) - Wikipedia, the free encyclopedia
Umbriel (um'-bree-ul) is a moon of Uranus discovered on 1851-10-24 by William Lassell.
The name "Umbriel" and the names of all four satellites of Uranus then known were suggested by John Herschel in 1852 at the request of Lassell ([2]).
Umbriel is the 'dusky melancholy sprite' in Alexander Pope's The Rape of the Lock, and the name suggests the Latin umbra, shadow.

Umbriel è la terza luna di Urano in ordine di grandezza.
Il nome Umbriel, e i nomi di tutti i quattro satelliti di Urano allora conosciuti, furono suggeriti da John Herschel nel 1852, su richiesta di Lassell.
Casualmente, il colore scuro di Umbriel ben si addice al suo nome: Umbriel è l'"oscuro folletto della malinconia" in The Rape of the Lock di Alexander Pope, ed il nome richiama la parola latina umbra, ombra.

The southern hemisphere of Umbriel displays heavy cratering in this Voyager 2 image, taken Jan. 24, 1986, from a distance of 557,000 kilometers (346,000 miles).
Umbriel is the darkest of Uranus' larger moons and the one that appears to have experienced the lowest level of geological activity.
Umbriel is heavily cratered but lacks the numerous bright-ray craters seen on the other large Uranian satellites; this results in a relatively uniform surface albedo (reflectivity).

Umbriel [UM-bree-ul] is the darkest satellite of Uranus.

The moon of Uranus – Umbriel (II) – was discovered along with Ariel in Octomber 24, 1851 by W. Lassell.
An interesting feature of Umbriel is that its surface is the darkest of the Uranian moons.
Detecting Umbriel's movement by Lasell and comparing the shifts with the changes in the position of Uranus allowed him to determine that it is a true satellite (and not a distant body only projected on the plane of sight).

Umbriel said they were to remain there until “something happened.” The agents were puzzled, and were even more surprised when something did happen: the Knight's Amundsen Base radioed them about a new island that had risen just north of Ross Sea.

Umbriel is the darkest of the large moons, with huge craters peppering its surface.
Umbriel has a paucity of what are known as bright ray craters, which are formed on an older, darker surface when bright, submerged ice is excavated and sprayed by meteoroid impacts.
In contrast, the surface of Ariel, the brightest of the Uranian moons, is relatively free of pockmarks due to volcanism that periodically erases the damage done by foreign projectiles.

Indeed, a case might be made for using Umbriel rather than Modula-2 as the first teaching language for a wider audience.
However, an investigation is under way to add simple classes to Umbriel, perhaps along the lines of those used in FST Modula-2, to which students in our regular courses have adapted with great ease.
