Astronomers have developed a new way to trace the paths of potential “city-killer” comets years before they come close to the Earth.. The breakthrough technique, described in a yet-to-be peer ...
By studying the composition of meteorites that have landed over the years and the asteroids populating our solar system, astronomers have determined that about 70% of known meteorite impacts came ...
A Belgian-Dutch team of scientists says it has created the first “treasure map” showing where meteorites may be found On the hunt for meteorites, researchers look to a data-based 'treasure map ...
Meteoritics [note 1] is the science that deals with meteors, meteorites, and meteoroids. [ note 2 ] [ 2 ] [ 3 ] It is closely connected to cosmochemistry , mineralogy and geochemistry . A specialist who studies meteoritics is known as a meteoriticist .
ANSMET (Antarctic Search for Meteorites) is a program funded by the Office of Polar Programs of the National Science Foundation that looks for meteorites in the Transantarctic Mountains. This geographical area serves as a collection point for meteorites that have originally fallen on the extensive high-altitude ice fields throughout Antarctica .
Few meteorites are large enough to create large impact craters. Instead, they typically arrive at the surface at their terminal velocity and, at most, create a small pit. NWA 859 iron meteorite showing effects of atmospheric ablation The impact pit made by a 61.9-gram Novato meteorite when it hit the roof of a house on 17 October 2012.
The Geminids, considered one of the best and most reliable meteor showers of the year, is underway and is set to peak Friday night into early Saturday. The shower will peak under a nearly full ...
CAMS [3] networks around the world use an array of low-light video surveillance cameras to collect astrometric tracks and brightness profiles of meteors in the night sky. . Triangulation of those tracks results in the meteor's direction and speed, from which the meteors’ orbit in space is calculated and the material's parent body can be identifi
