While the Moon is the most explored extraterrestrial object by humans, the discovery is a reminder that we have barely scratched the surface of its mysteries.

NASA has taken a breathtaking new image of near-Earth asteroid Bennu, captured by its OSIRIS-REx spacecraft from its new, second orbit of the extraterrestrial object.

The object in Patient Seventeen's leg had a number of hallmarks of an extraterrestrial object as far as its elemental composition is concerned, but this is far from conclusive evidence.

A video camera on the roof of Montrose High School, part of a state-wide astronomical network, captured images of the extraterrestrial object as it pierced the atmosphere at a speed of 36,000 miles per hour.

Shock metamorphism occurs when an extraterrestrial object (a meteorite for instance) collides with the Earth's surface. Impact metamorphism is, therefore, characterized by ultrahigh pressure conditions and low temperature. The resulting minerals (such as SiO2 polymorphs coesite and stishovite) and textures are characteristic of these conditions.

The story played a part in the development of Clarke's 1968 novel 2001: A Space Odyssey. During 1964, Clarke and Stanley Kubrick were working on the story for the film, and it was at first envisaged that the discovery of an extraterrestrial object would be the climax. "Before Eden" was one of several of Clarke's short stories sold to Kubrick, to provide background material for the exploration of the Solar System before its discovery. It was later decided that the extraterrestrial object would be found early in the story, and the short stories were discarded; the following year, Clarke bought them back from Kubrick.

The Sylacauga meteorite is the first documented extraterrestrial object to have injured a human being. The grapefruit-sized fragment crashed through the roof of a farm house, bounced off a large wooden console radio, and hit Hodges while she napped on a couch. The 34-year-old woman was badly bruised on one side of her body, but was able to walk. The event received worldwide publicity.

When a velocity-driven extraterrestrial object impacts a relatively stationary body, an impact crater forms. Initial crater(s) to form from the collision are known as primary craters or impact craters. Material expelled from primary craters may form secondary craters (secondaries) under a few conditions: # Primary craters must already be present. # The gravitational acceleration of the extraterrestrial body must be great enough to drive the ejected material back toward the surface.

UA is home to several museums, cultural facilities and historical landmarks. The Alabama Museum of Natural History at Smith Hall exhibits Alabama's rich natural history. The oddest artifact there could be the Sylacauga meteorite, the largest known extraterrestrial object to strike a human being who survived. The Paul W. Bryant Museum houses memorabilia and exhibits on the history of UA athletic programs, most notably the tenure of football coach Paul "Bear" Bryant.

After a mysterious, extraterrestrial object crashes in the mining town of Salena, Arizona, the government dispatches a team of Marines to contain the possible threat. Meanwhile, a group of death row inmates ambush their prison bus and take the guards hostage. The criminals include Brando, from the Italian Mafia, Colburn, an African-American gangster, Alano, a Hispanic gang member, and a Neo-Nazi skinhead named Albany.Alien Invasion Arizona (2007) - Horror Movie Reviews - Horror of Buried.

Reports of a downed extraterrestrial object gain the attention of U.S. government agents. Although disappointed that they find no living specimens, the agents take an "eyewitness" into custody to observe him after they find he is no longer blind. David Chamberlain, a mechanic who has not recovered from the death of his wife Jane, struggles to keep his job. Zach, a veteran of a war currently ongoing in Iran, asks for a job, though David must turn him down.

During the final episode, the extraterrestrial object known as Bird Human by the Mayan people awakens, assimilating Sara into the cockpit located at its head. He manages to break through the Bird Human's attacks and makes Sara realise that it is Shynn instead of an evil spirit (called a "Kadun" by the Mayans). The UN forces, however, see the Bird Human as a liability and launch reaction weapons at it. Sara sacrifices herself to save Shynn and the rest of the Mayan Island which would have been destroyed by the nuclear fallout.

Iridium radioisotopes are used in some radioisotope thermoelectric generators. Iridium is found in meteorites in much higher abundance than in the Earth's crust. For this reason, the unusually high abundance of iridium in the clay layer at the Cretaceous–Paleogene boundary gave rise to the Alvarez hypothesis that the impact of a massive extraterrestrial object caused the extinction of dinosaurs and many other species 66 million years ago. Similarly, an iridium anomaly in core samples from the Pacific Ocean suggested the Eltanin impact of about 2.5 million years ago.

Several of London's stories would today be classified as science fiction. "The Unparalleled Invasion" describes germ warfare against China; "Goliath" is about an irresistible energy weapon; "The Shadow and the Flash" is a tale about two brothers who take different routes to achieving invisibility; "A Relic of the Pliocene" is a tall tale about an encounter of a modern-day man with a mammoth. "The Red One" is a late story from a period when London was intrigued by the theories of the psychiatrist and writer Jung. It tells of an island tribe held in thrall by an extraterrestrial object.

The test confirms her special skills and later makes the island's inhabitants the focus of research and armed conflict. Due to this incident Sara grows up to become suspicious of outsiders and very protective of her people's beliefs. She resents the wind of change that the abrupt arrival of U.N. pilot Shynn Kudo brings to her home, yet she realizes how powerless she is against it as she foresees the destruction and violence that is to come. In the final episode, the extraterrestrial object known as Bird Human awakens due to Sara's chant, assimilating her into its head.

Manicouagan reservoir in Quebec, a massive crater formed by a Late Triassic impact. Radiometric dating has determined that it is about 13 million years older than the Triassic–Jurassic boundary, and thus an unlikely candidate for a mass extinction. Some have hypothesized that an impact from an asteroid or comet may have caused the Triassic–Jurassic extinction, similar to the extraterrestrial object which was the main factor in the Cretaceous–Paleogene extinction about 66 million years ago, as evidenced by the Chicxulub crater in Mexico. However, so far no impact crater of sufficient size has been dated to precisely coincide with the Triassic–Jurassic boundary.

Atmospheric focusing is a phenomenon occurring when a large shock wave is produced in the atmosphere, as in a nuclear explosion or large extraterrestrial object impact. The shock wave is refracted horizontally by density variations in the atmosphere so that it can have impacts in localized areas much further away than the theoretical extent of its blast effect. In large bombs, some effects may thus be found hundreds of kilometers from the blast site (such as in the case of the Tsar Bomba test, where damage was caused up to approximately 1,000 km away). This effect operates similarly to the patterns made by sunlight on the bottom of a pool, the difference is that the light is bent at the contact point with the water while the shock wave is distorted by density variations (e.g.
