Belton Regio
Belton Regio (formerly Cthulhu Macula or Cthulhu Regio) is a prominent surface feature of the dwarf planet Pluto. It is an elongated dark region along Pluto's equator, long and one of the darkest features on its surface. After its discovery in 2015, the feature was provisionally named after the fictional deity Cthulhu from the works of H. P. Lovecraft and others, as it was most popular name in its category in an online poll conducted earlier that year. In 2023, an official name was adopted by the International Astronomical Union honoring astronomer Michael J. Belton. Description The macula lies west of the Sputnik Planitia region of Tombaugh Regio, also known as Pluto's "heart", and to the east of Meng-P'o, the easternmost of Pluto's "Brass Knuckles". The dark color of the region is speculated to be the result of a "tar" made of complex hydrocarbons called tholins covering the surface, which form from methane and nitrogen in the atmosphere interacting with ultraviolet light ...

Cthulhu Regio
Cthulhu Macula (formerly ''Cthulhu Regio'') is a prominent surface feature of the dwarf planet Pluto, that is reminiscent of a whale in shape. It is an elongated dark region along Pluto's equator, long and one of the darkest features on Pluto. It is west of the Sputnik Planitia region of Tombaugh Regio, also known as Pluto's "heart", and to the east of Meng-P'o, the easternmost of Pluto's "Brass Knuckles". Description The dark color of the region is speculated to be the result of a "tar" made of complex hydrocarbons called tholins covering the surface, which form from methane and nitrogen in the atmosphere interacting with ultraviolet light and cosmic rays. Tholins have been observed on other planetary bodies, such as Iapetus, Umbriel, and in the atmosphere of Titan, although the irregular and disconnected nature of the dark spots on Pluto has not yet been explained. The presence of craters within Cthulhu indicates that it is perhaps billions of years old, in contrast to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Umbriel (moon)
Umbriel is a moon of Uranus discovered on October 24, 1851, by William Lassell. It was discovered at the same time as Ariel and named after a character in Alexander Pope's 1712 poem ''The Rape of the Lock''. Umbriel consists mainly of ice with a substantial fraction of rock, and may be differentiated into a rocky core and an icy mantle. The surface is the darkest among Uranian moons, and appears to have been shaped primarily by impacts. However, the presence of canyons suggests early endogenic processes, and the moon may have undergone an early endogenically driven resurfacing event that obliterated its older surface. Covered by numerous impact craters reaching in diameter, Umbriel is the second most heavily cratered satellite of Uranus after Oberon. The most prominent surface feature is a ring of bright material on the floor of Wunda crater. This moon, like all moons of Uranus, probably formed from an accretion disk that surrounded the planet just after its formation. Th ...

The Call Of Cthulhu
"The Call of Cthulhu" is a short story by American writer H. P. Lovecraft. Written in the summer of 1926, it was first published in the pulp magazine ''Weird Tales'' in February 1928. Inspiration The first seed of the story's first chapter ''The Horror in Clay'' came from one of Lovecraft's own dreams he had in 1919, which he described briefly in two different letters sent to his friend Rheinhart Kleiner on May 21 and December 14, 1920. In the dream, Lovecraft is visiting an antiquity museum in Providence, attempting to convince the aged curator there to buy an odd bas-relief Lovecraft himself had sculpted. The curator initially scoffs at him for trying to sell something recently made to a museum of antique objects. Lovecraft then remembers himself answering the curator with the response This can be compared to what the character of Henry Anthony Wilcox tells the main character's uncle while showing him his sculpted bas-relief for help in reading hieroglyphs on it which came ...

New Horizons
''New Horizons'' is an interplanetary space probe that was launched as a part of NASA's New Frontiers program. Engineered by the Johns Hopkins University Applied Physics Laboratory (APL) and the Southwest Research Institute (SwRI), with a team led by Alan Stern, the spacecraft was launched in 2006 with the primary mission to perform a flyby study of the Pluto system in 2015, and a secondary mission to fly by and study one or more other Kuiper belt objects (KBOs) in the decade to follow, which became a mission to 486958 Arrokoth. It is the fifth space probe to achieve the escape velocity needed to leave the Solar System. On January 19, 2006, ''New Horizons'' was launched from Cape Canaveral Space Force Station by an Atlas V rocket directly into an Earth-and-solar escape trajectory with a speed of about . It was the fastest (average speed with respect to Earth) man-made object ever launched from Earth. It is not the fastest speed recorded for a spacecraft, which as of 2021 ...

Hillary Montes
The Hillary Montes or (less officially, Hillary Mountains) are mountains that reach above the surface of the dwarf planet Pluto. They are located northwest of Tenzing Montes in the southwest border area of Sputnik Planitia in the south of Tombaugh Regio (or the part of Tombaugh Regio south of the equator). The Hillary Montes were first viewed by the ''New Horizons'' spacecraft on 14 July 2015, and announced by NASA on 24 July 2015. Naming The mountains are named after Sir Edmund Hillary, New Zealand mountaineer, who, along with Nepalese Sherpa mountaineer, Tenzing Norgay, were the first climbers to reach the summit of the highest peak on Earth, Mount Everest, on 29 May 1953. On 7 September 2017, the name ''Hillary Montes'' was officially approved together with the names of Tombaugh Regio and twelve other nearby surface features. Relative size The Hillary Montes rise to high from base to peak, about half as high as the Tenzing Montes. The Hillary Montes are similar in heigh ...

Beatrice Fossa
This is a list of named geological features on Pluto, identified by scientists working with data from the ''New Horizons'' spacecraft. The International Astronomical Union (IAU) officially approved the first 14 names on 8 August 2017 (announced 7 September 2017), with additional names following in each subsequent year, but many of the names listed on this page are still informal. The IAU has determined that names will be chosen from the following themes: * Names for the underworld from the world's mythologies * Gods, goddesses, and dwarfs associated with the underworld * Heroes and other explorers of the underworld * Writers associated with Pluto and the Kuiper belt * Pioneering space missions and spacecraft * Scientists and engineers associated with Pluto and the Kuiper belt Cavi A cavus is a hollow or steep-sided depression. The following is a list of official and unofficial names chosen by the ''New Horizons'' team. Colles A collis is a low hill. Plutonian colles are ...
