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 ...
[5] [7] The meteorite is estimated between 50 and 90 million tons and likely originated in the asteroid belt between Mars and Jupiter. [8] The Glasford crater was discovered by the Central Illinois Light Company (formerly CILCO, now Ameren) while drilling wells for underground natural gas storage.
A meteorite mineral is a mineral found chiefly or exclusively within meteorites or meteorite-derived material. [citation needed] This is a list of those minerals, excluding minerals also commonly found in terrestrial rocks. As of 1997 there were approximately 295 mineral species which have been identified in meteorites. [1]

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 ...
The two discovered a new element in a molybdenum sample that was used in a cyclotron, the first element to be discovered by synthesis. It had been predicted by Mendeleev in 1871 as eka-manganese. [172] [173] [174] In 1952, Paul W. Merrill found its spectral lines in S-type red giants. [175]
The Weaubleau structure is a probable meteorite impact site in western Missouri near the towns of Gerster, Iconium, Osceola, and Vista. It is believed to have been caused by a 1,200-foot (370 m) meteoroid between 335 and 340 million years ago [ 1 ] during the middle Mississippian Period (Latest Osagean to Earliest Meramecian ).
In 2020, researchers at Australian National University found by accident they were able to produce lonsdaleite at room temperatures using a diamond anvil cell. [ 28 ] [ 29 ] In 2021, Washington State University's Institute for Shock Physics published a paper stating that they created lonsdaleite crystals large enough to measure their stiffness ...
