Alcott is an impact crater on Venus. [1] Lava produced by a volcano at one point filled the crater and altered its rim. [1] [2]
The Moon is Earth's only natural satellite. It orbits at an average distance of 384,400 km (238,900 mi), about 30 times Earth's diameter. The Moon always presents the same side to Earth, because gravitational pull has locked its rotation to the planet. This results in the lunar day of 29.5 Earth days matching the lunar month. The Moon's gravitational pull – and to a lesser extent the Sun's – are the main drivers of the tides.
Aden is a port city located in Yemen in the southern part of the Arabian peninsula, positioned near the eastern approach to the Red Sea. It is situated approximately 170 km east of the Bab-el-Mandeb strait and north of the Gulf of Aden. With its strategic location on the coastline, Aden serves as a gateway between the Red Sea and the Arabian Sea, making it a crucial maritime hub connecting Africa, Asia, and the Middle East. As of 2023, Aden City has a population of approximately 1,080,000 residents, making it one of the largest cities in Yemen.
The Battle of the Crater was a battle of the American Civil War, part of the Siege of Petersburg. It took place on Saturday, July 30, 1864, between the Confederate Army of Northern Virginia, commanded by General Robert E. Lee, and the Union Army of the Potomac, commanded by Major General George G. Meade.
Meteor Crater or Barringer Crater is an impact crater about 37 mi (60 km) east of Flagstaff and 18 mi (29 km) west of Winslow in the desert of northern Arizona, United States. The site had several earlier names, and fragments of the meteorite are officially called the Canyon Diablo Meteorite, after the adjacent Canyon Diablo.
Crater Lake is a volcanic crater lake in south-central Oregon in the Western United States. It is the main feature of Crater Lake National Park and is famous for its deep blue color and water clarity. The lake partly fills a 2,148-foot-deep (655 m) caldera that was formed around 7,700 years ago by the collapse of the volcano Mount Mazama. No rivers flow into or out of the lake; the evaporation is compensated for by rain and snowfall at a rate such that the total amount of water is replaced every 250 years. With a depth of 1,949 feet (594 m), the lake is the deepest in the United States. In the world, it ranks tenth for maximum depth, as well as third for mean (average) depth.
The Chicxulub crater is an impact crater buried underneath the Yucatán Peninsula in Mexico. Its center is offshore, but the crater is named after the onshore community of Chicxulub Pueblo. It was formed slightly over 66 million years ago when a large asteroid, about ten kilometers in diameter, struck Earth. The crater is estimated to be 180 kilometers in diameter and 20 kilometers in depth. It is the second largest confirmed impact structure on Earth, and the only one whose peak ring is intact and directly accessible for scientific research.
Joseph Force Crater was an American lawyer who served as a New York State Supreme Court Justice and mysteriously vanished shortly after the state began an investigation into corruption in New York City. Despite massive publicity, the missing person case was never solved and was officially closed forty years after Crater was declared dead.
The far side of the Moon is the lunar hemisphere that always faces away from Earth, opposite to the near side, because of synchronous rotation in the Moon's orbit. Compared to the near side, the far side's terrain is rugged, with a multitude of impact craters and relatively few flat and dark lunar maria ("seas"), giving it an appearance closer to other barren places in the Solar System such as Mercury and Callisto. It has one of the largest craters in the Solar System, the South Pole–Aitken basin. The hemisphere has sometimes been called the "dark side of the Moon", where "dark" means "unknown" instead of "lacking sunlight" – each side of the Moon experiences two weeks of sunlight while the opposite side experiences two weeks of night.
Ngorongoro Conservation Area is a protected area and a UNESCO World Heritage Site located in Ngorongoro District, 180 km (110 mi) west of Arusha City in Arusha Region, within the Crater Highlands geological area of northern Tanzania. The area is named after Ngorongoro Crater, a large volcanic caldera within the area. The Ngorongoro Conservation Area Authority administers the conservation area, an arm of the Tanzanian government, and its boundaries follow the boundary of the Ngorongoro District in Arusha Region. The western portion of the park abuts the Serengeti National Park, and the area comprising the two parks and Kenya's Maasai Mara game reserve is home to Great Migration, a massive annual migration of millions of wildebeest, zebras, gazelles, and other animals. The conservation area also contains Olduvai Gorge, one of the most important paleoanthropological sites in the world.
James Turrell is an American artist known for his work within the Light and Space movement. Much of Turrell's career has been devoted to a still-unfinished work, Roden Crater, a natural cinder cone crater located outside Flagstaff, Arizona, that he is turning into a massive naked-eye observatory; and for his series of skyspaces, enclosed spaces that frame the sky.
Taal Volcano is a large caldera filled by Taal Lake in the Philippines. Located in the province of Batangas about 50 kilometers (31 mi) south of Manila, the volcano is the second most active volcano in the country with 38 recorded historical eruptions, all of which were concentrated on Volcano Island, near the middle of Taal Lake. The caldera was formed by prehistoric eruptions between 140,000 and 5,380 BP.
Yuty is a crater on Mars in Chryse Planitia, named after the town of Yuty in Paraguay. It measures approximately 19 kilometres in diameter, and is surrounded by complex ejecta lobes, which are a distinctive characteristic of martian impact craters.
Cunitz is a crater on Venus at latitude 14.5, longitude 350.9 in western Eistla Regio. It is 48.6 km in diameter and was named for a 17th-century Silesian astronomer Maria Cunitz.
Balch is a crater on Venus at latitude 29.9, longitude 282.9 in Devana Chasma, Central Beta Regio. It is 40 km in diameter and named after Emily Balch, though it was originally designated Somerville crater. This crater is one of the few examples of tectonically modified craters seen on Venus. Approximately half the crater was subsumed into a valley. The absence of such craters indicates a possible cessation of tectonic deformation on Venus at some point in history.
Aurelia is a crater on Venus. It has a large dark surface up range from the crater; lobate flows emanating from crater ejecta, and very radar-bright ejecta and floor. The crater takes its name from Aurelia.
Halemaʻumaʻu is a pit crater within the much larger Kīlauea Caldera at the summit of Kīlauea volcano on island of Hawaiʻi. The roughly circular crater was 770 meters (2,530 ft) x 900 m (2,950 ft) before collapses that roughly doubled the size of the crater after May 3, 2018. Following the collapses of 2018, the bottom of Halemaʻumaʻu was roughly 600 m (2,000 ft) below the caldera floor. Halemaʻumaʻu is home to Pele, goddess of fire and volcanoes, according to the traditions of Hawaiian religion. Halemaʻumaʻu means "house of the ʻāmaʻu fern".
Mount Sharp, officially Aeolis Mons, is a mountain on Mars. It forms the central peak within Gale crater and is located around 5.08°S 137.85°E, rising 5.5 km (18,000 ft) high from the valley floor. Its ID in the United States Geological Survey's Gazetteer of Planetary Nomenclature is 15000.
Maungawhau / Mount Eden is a scoria cone and Tūpuna Maunga in the Mount Eden suburb of Auckland, New Zealand. The cone is part of the Auckland volcanic field, the tallest located on the isthmus.
The Underground Railroad is a historical fiction novel by American author Colson Whitehead, published by Doubleday in 2016. The alternate history novel tells the story of Cora, a slave in the Antebellum South during the 19th century, who makes a bid for freedom from her Georgia plantation by following the Underground Railroad, which the novel depicts as a rail transport system with safe houses and secret routes. The book was a critical and commercial success, hitting the bestseller lists and winning several literary awards, including the Pulitzer Prize for Fiction, the National Book Award for Fiction, the Arthur C. Clarke Award, and the 2017 Andrew Carnegie Medal for Excellence. A TV miniseries adaptation, written and directed by Barry Jenkins, was released in May 2021.
