In physics, a shock wave (also spelled shockwave), or shock, is a type of propagating disturbance that moves faster than the local speed of sound in the medium. Like an ordinary wave, a shock wave carries energy and can propagate through a medium, but is characterized by an abrupt, nearly discontinuous, change in pressure , temperature , and ...
The meteor and meteorite are named after Chelyabinsk Oblast, over which the meteor exploded.An initial proposal was to name the meteorite after Lake Chebarkul, where one of its major fragments impacted and made a 6-metre-wide (20 ft) hole in the frozen lake surface.
Shatter cones are rare geological features that are only known to form in the bedrock beneath meteorite impact craters or underground nuclear explosions. They are evidence that the rock has been subjected to a shock with pressures in the range of 2–30 GPa (290,000–4,350,000 psi). [1] [2] [3]
Meteorites might look like boring bits of rock – but each one has a fascinating story.
Scientists believe they can find a meteor blast in Earth’s history strong enough to change the climate and, as a result, the animals that lived on Earth. Evidence may exist for a comet shockwave ...

A "meteorite fall", also called an "observed fall", is a meteorite collected after its arrival was observed by people or automated devices. Any other meteorite is called a "meteorite find". [ 43 ] [ 44 ] There are more than 1,100 documented falls listed in widely used databases, [ 45 ] [ 46 ] [ 47 ] most of which have specimens in modern ...
A meteor that exploded in a spectacular fireball over Niagara Falls in 2022 was the smallest asteroid ever measured, a new study has found.. The asteroid, spotted by astronomers just hours before ...
