Al-Box News newspaper summarizes for you, dear followers, the most important of what came from,
A bright fireball covering the entire sky was observed in southern Ontario, Canada, at 11:37 pm on Sunday, April 17, by a network of cameras that
Analysis of video data conducted by researchers from the University of Southern Ontario indicates that this ball is a meteor that disintegrated, and that parts of it likely reached Earth near the eastern shore of Lake Simcoe, north of Argyle.
The Department of Physics and Astronomy at the University of Southern Ontario operates a network of cameras that cover the entire sky and constantly monitor it for meteors.
Denis Vida, a specialist in the study of meteors, confirmed that more than 12 cameras covering the entire sky for a network of western and southern Ontario captured the event, as it was captured north of Toronto late on Sunday evening, as did a number of cameras operated by citizen scientists, via what is known Global Meteor Network (GMN).
“This fireball was especially important because it was moving slowly, it was in the orbit of an asteroid and it ended up very low in the atmosphere, and these are all good indicators of the survival of the material,” says Vida, a post-doctoral fellow in astronomy in a report published Wednesday on the university’s website. .
He adds that this event is important because the Western Meteorites Research Group has high-quality video data of its passage through the atmosphere so that they can calculate the origin of the rocks in our solar system, and preliminary results indicate that the fireball became visible for the first time at an altitude of 90 km and moved approximately north.
It is believed that the initial mass of the meteorite was about 10 kilograms, and we expect the presence of tens to hundreds of grams of material on Earth, and this is of great interest to researchers as its study helps us understand the formation and evolution of the solar system, as Veda confirms.
Meteorites are recognizable by their dark, often scalloped exterior, and are usually denser than “ordinary” rocks and are often attracted to magnets due to their mineral content.
Meteorites are not dangerous, but if recovered, they are best placed in a clean plastic bag or wrapped in aluminum foil, and should also be handled as little as possible to help preserve their scientific value.
In Canada, meteorites belong to the owner of the land on which they are found, and if individuals are planning to search, they must always obtain permission from the landowner before venturing into private land.
