Using cameras fitted on probes orbiting Mars, researchers have observed morning frost forming inside the calderas of the planet’s volcanoes for the first time. Water frost detected on Mars ...
For example, the tallest volcano on Mars, Olympus Mons, is 550 km across and 21 km high. It is nearly 100 times greater in volume than Mauna Loa in Hawaii, the largest active shield volcano on Earth. Geologists think one of the reasons that volcanoes on Mars are able to grow so large is because Mars lacks plate tectonics.
Olympus Mons (/ ə ˌ l ɪ m p ə s ˈ m ɒ n z, oʊ-/; [4] Latin for 'Mount Olympus') is a large shield volcano on Mars.It is over 21.9 km (13.6 mi; 72,000 ft) high as measured by the Mars Orbiter Laser Altimeter (MOLA), [5] about 2.5 times the elevation of Mount Everest above sea level.
Ceraunius Tholus is a volcano on Mars located in the Tharsis quadrangle at 24.25° north latitude and 262.75° east longitude, [1] part of the Uranius group of volcanoes.It is 130 kilometres (81 mi) across, approximately 8,500 metres (27,887 ft) high [2] and is named after a classical albedo feature name.
Arsia Mons once spewed molten rock across the surface of Mars, but some smaller volcanic features may have come from another source. In a select few places on Earth, mud erupts rather than molten ...
Alba Mons (formerly and still occasionally known as Alba Patera, a term that has since been restricted to the volcano's summit caldera; [2] also initially known as the Arcadia ring [3]) is a volcano located in the northern Tharsis region of the planet Mars. It is the biggest volcano on Mars in terms of surface area, with volcanic flow fields ...
This week, spot the shipwreck of a legendary polar explorer, spy frost on the tops of Martian volcanoes, meet a vegetarian piranha relative, and more. Newly discovered polar shipwreck may contain ...
Tharsis is a land of great volcanoes. Olympus Mons is the tallest known volcano in the Solar System; it is 100 times larger than any volcano on Earth. Ascraeus Mons and Pavonis Mons are at least 200 miles across and are over six miles above the plateau that they sit on—and, the plateau is three to four miles above the zero altitude of Mars. [4]
