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 ...
Shock stationed clay mineral from the Puchezh-Katunsky meteorite crater. Meteorite shock stage is a measure of the degree of fracturing of the matrix of a common chondrite meteorite. [1]
Shock waves are common in astrophysical environments. [1]Because of the low ambient density, most astronomical shocks are collisionless.This means that the shocks are not formed by two-body Coulomb collisions, since the mean free path for these collisions is too large, often exceeding the size of the system.
A meteor air burst is a type of air burst in which a meteoroid explodes after entering a planetary body's atmosphere. This fate leads them to be called fireballs or bolides , with the brightest air bursts known as superbolides .
The bright flash of the shockwave, or as astronomers call it the "shock breakout," pushes outward as the distant body turns from star to supernova.
Fortunately, the waxing moon sets early during the peak viewing nights, minimizing light pollution and enhancing the visibility of the meteors. So, bundle up, find a cozy spot under the night sky ...
Desert glass – natural glass found in deserts formed from the silica in sand as a result of lightning strikes or meteor impacts. Differentiated – a meteorite that has undergone igneous differentiation. (See: achondrite) Differentiation – usually the process of a planetesimal forming an iron core and silicate mantle.
The Quadrantid meteor shower is one of the strongest, and quickest, meteor showers of the year. Here’s what you need to know to observe it during peak activity.
