Tenzing Montes
The Tenzing Montes (formerly Norgay Montes) are icy mountains near the Hillary Montes that reach up to above the surface of the dwarf planet Pluto, bordering the southwest region of Sputnik Planitia in the south of Tombaugh Regio (or the part of Tombaugh Regio south of the equator). They are the highest mountain range on Pluto, and also the steepest, with a mean slope of 19.2 degrees. Naming The mountains, first viewed by the ''New Horizons'' spacecraft on 14 July 2015, and announced by NASA on 15 July 2015, are named after the Nepalese mountaineer Tenzing Norgay, who, along with Sir Edmund Hillary, made the first successful ascent of the highest peak on Earth, Mount Everest (29 May 1953). The mountains were informally called ''Norgay Montes'' by the ''New Horizons'' team, but that name was later changed from ''Norgay'' to ''Tenzing''.In Nepali, the last name is given first, so ''Tenzing'' is the last name while ''Norgay'' is the first name. On 7 September 2017, the name ''Ten ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Extraterrestrial Mountains
Extraterrestrial refers to any object or being beyond ( extra-) the planet Earth (terrestrial). It is derived from the Latin words ''extra'' ("outside", "outwards") and ''terrestris'' ("earthly", "of or relating to the Earth"). It may be abbreviated as "E.T." Extraterrestrial may also refer to: General topics * Extraterrestrial life, life that occurs outside of Earth and that probably did not originate from Earth ** Extraterrestrial intelligence, hypothetical intelligent extraterrestrial life ** Extraterrestrials in fiction ** List of alleged extraterrestrial beings Media and entertainment * ''Extraterrestrial'' (TV documentary), a program on the National Geographic Channel * "Extraterrestrial" (song), a 2018 song by Tynan and Kompany * "E.T."

List Of Tallest Mountains In The Solar System
This is a list of the tallest mountains in the Solar System. This list includes peaks on all celestial bodies where significant mountains have been detected. For some celestial bodies, different peaks are given across different types of measurement. The solar system's tallest mountain is the central peak of Rheasilvia on the asteroid Vesta, estimated at up to 25 km from peak to base. Among the terrestrial planets the tallest mountain is Olympus Mons on Mars, at 21.9 km. __TOC__ List Heights are given from base to peak (although a precise definition for mean base level is lacking). Peak elevations above sea level are only available on Earth, and possibly Titan. On other worlds, peak elevations above an equipotential surface or a reference ellipsoid could be used if enough data is available for the calculation, but this is often not the case. Tallest mountains by elevation * Olympus Mons * Equatorial Ridge * Boösaule Mons * Ascraeus Mons * Ionian Mons * Elysium Mo ...

Geology Of Pluto
The geology of Pluto consists of the characteristics of the surface, crust, and interior of Pluto. Because of Pluto's distance from Earth, in-depth study from Earth is difficult. Many details about Pluto remained unknown until 14 July 2015, when '' New Horizons'' flew through the Pluto system and began transmitting data back to Earth. When it did, Pluto was found to have remarkable geologic diversity, with ''New Horizons'' team member Jeff Moore saying that it "is every bit as complex as that of Mars". The final ''New Horizons'' Pluto data transmission was received on 25 October 2016. In June 2020, astronomers reported evidence that Pluto may have had a subsurface ocean, and consequently may have been habitable, when it was first formed. Surface More than 98 percent of Pluto's surface consists of solid nitrogen, with traces of methane and carbon monoxide. The face of Pluto oriented toward Charon contains more solid methane, whereas the opposite face contains more nitrogen a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geography Of Pluto
The geography of Pluto entails the delineation and characterization of regions on Pluto. Plutonian geography is mainly focused on what is called physical geography on Earth; that is, the distribution of physical features across Pluto and their cartographic representations. On 14 July 2015, the ''New Horizons'' spacecraft became the first spacecraft to fly by Pluto. During its brief flyby, ''New Horizons'' made detailed geographical measurements and observations of Pluto and its moons. Coordinate system orientation Pluto may be defined as having retrograde rotation and an axial tilt of 60 degrees, or prograde rotation and a tilt of 120 degrees. Following the latter convention (the right-hand rule), the hemisphere currently in daylight is the northern one, with much of the southern hemisphere in darkness. This is the convention used by the International Astronomical Union (IAU) and the ''New Horizons'' team, and their maps put the sunlit hemisphere on top. However, older sources may ...

Atmosphere Of Pluto
The atmosphere of Pluto is the tenuous layer of gases surrounding Pluto. It consists mainly of nitrogen (N2), with minor amounts of methane (CH4) and carbon monoxide (CO), all of which are vaporized from their ices on Pluto's surface. It contains layered haze, probably consisting of heavier compounds which form from these gases due to high-energy radiation. The atmosphere of Pluto is notable for its strong and not completely clear seasonal changes caused by peculiarities of the orbital and axial rotation of Pluto. The surface pressure of the atmosphere of Pluto, measured by ''New Horizons'' in 2015, is about (), roughly 1/100,000 of Earth's atmospheric pressure. The temperature on the surface is , but it quickly grows with altitude due to methane-generated greenhouse effect. Near the altitude it reaches , and then slowly decreases. Pluto is the only trans-Neptunian object with a known atmosphere. Its closest analog is the atmosphere of Triton, although in some aspects it resem ...

List Of Geological Features On Pluto
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 a ...

Bradford Washburn
Henry Bradford Washburn Jr. (June 7, 1910 – January 10, 2007) was an American explorer, mountaineer, photographer, and cartographer. He established the Boston Museum of Science, served as its director from 1939–1980, and from 1985 until his death served as its Honorary Director (a lifetime appointment). Bradford married Barbara Polk in 1940, they honeymooned in Alaska making the first ascent of Mount Bertha together. Washburn is especially noted for exploits in four areas. *He was one of the leading American mountaineers in the 1920s through the 1950s, putting up first ascents and new routes on many major Alaskan peaks, often with his wife, Barbara Washburn, one of the pioneers among female mountaineers and the first woman to summit Denali (Mount McKinley). *He pioneered the use of aerial photography in the analysis of mountains and in planning mountaineering expeditions. His thousands of striking black-and-white photos, mostly of Alaskan peaks and glaciers, are known for t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
