Soon after, reports of falling debris were recorded near the village of Park Forest, Illinois. At least two houses in Park Forest were struck, as well as the fire station. In the following days, this event was officially named the Park Forest meteorite, as numerous stones or fragments were recovered in the area. The total mass recovered is ...
Geologists estimate the meteor released a large amount of energy, roughly equivalent to 20,000 nuclear bombs, 460 million tons of TNT, or two to three times the energy of the Mount St. Helens eruption. [10] [8] According to research by geologist Charles Monson, the Glasford crater may be connected to the Great Ordovician Meteor Shower. [13] Dr.
Paleogeographic reconstruction showing the Illinois Basin area during the Middle Devonian period. [9] Almost all Silurian rocks in Illinois are deep-water limestone and dolomite deposits; reef habitats were common, and fossils of reef organisms are locally highly abundant, including corals, brachiopods, crinoids, stromatoporoids, and bryozoans.

Meteoric iron, sometimes meteoritic iron, [1] is a native metal and early-universe protoplanetary-disk remnant found in meteorites and made from the elements iron and nickel, mainly in the form of the mineral phases kamacite and taenite. Meteoric iron makes up the bulk of iron meteorites but is also found in other
The meteorite, S2, was first discovered in 2014. It hit the planet about 3.26 billion years ago and is estimated to have been up to 200 times larger than the space rock that later killed the ...
Diagram illustration the creation of new elements by the alpha process Nucleosynthesis is the process that creates new atomic nuclei from pre-existing nucleons (protons and neutrons) and nuclei. According to current theories, the first nuclei were formed a few minutes after the Big Bang , through nuclear reactions in a process called Big Bang ...
But there have been lingering questions because these meteorites could have been contaminated by terrestrial sources. The Bennu samples were obtained directly from an asteroid and were kept pristine.
The cause is speculated to be due to the samples having been riddled with lattice defects and impurities. [7] In addition to meteorite deposits, hexagonal diamond has been synthesized in the laboratory (1966 or earlier; published in 1967) [8] by compressing and heating graphite either in a static press or using explosives.
