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 ...
A blanket of ejecta is formed during the formation of meteor impact cratering and is composed usually of the materials of that are ejected from the cratering process. Ejecta materials are deposited on the preexisting layer of target materials and therefore it form an inverted stratigraphy than the underlying bedrock.
A meteor, known colloquially as a shooting star or falling star, is the visible passage of a glowing meteoroid, micrometeoroid, ...
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 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.
Shatter cones have a distinctively conical shape that radiates from the top (apex) of the cones repeating cone-on-cone in large and small scales in the same sample.. Sometimes they have more of a spoon shape on the side of a larger
Bolide from the French astronomy book Le Ciel; Notions 'Elémentaires d'Astronomie Physique (1877). The word bolide (/ ˈ b oʊ l aɪ d /; from Italian via Latin, from Ancient Greek βολίς (bolís) 'missile' [2] [3]) may refer to somewhat different phenomena depending on the context in which the word appears, and readers may need to make inferences to determine which meaning is intended in ...
