Origin of the Moon. New Concept

The origin of the Moon remains an unsolved problem of the planetary science. Researchers engaged in celestial dynamics, geophysics, and geochemistry are still discussing various models of creation of our closest cosmic neighbour. The most popular scenario, the impact hypothesis involving a collision early in the Earth's history, has been substantially challenged by the new data. The birth and development of a planet-moon system alway...

The Sun, Mercury and Venus

In 350 B.C.E., Aristotle, the great Greek philosopher, wrote that the Earth is the center of the solar system, and that all the other bodies in the solar system orbit the Earth while set into a complex series of spheres. However, in 1514 C.E., Nicolas Copernicus, a Prussian scientist and canon in the Catholic church, challenged these previous beliefs, theorizing that the center of the universe is not the Earth, but the Sun, that the ...

Defending Planet Earth: Near-Earth Object Surveys and Hazard Mitigation Strategies

The United States spends approximately $4 million each year searching for near-Earth objects (NEOs). The objective is to detect those that may collide with Earth. The majority of this funding supports the operation of several observatories that scan the sky searching for NEOs. This, however, is insufficient in detecting the majority of NEOs that may present a tangible threat to humanity. A significantly smaller amount of funding supp...
