In the far east of Canada, a meteorite hitting the earth's surface has been captured in sound and image for the first time. This was made public by the University of Alberta, where the remains of the chunk were analyzed. The recordings were made with a security camera from Amazon subsidiary Ring, and the impact can be clearly heard. The meteorite itself can only be guessed at, but the impact clearly stirred up dust, which can be recognized. There is also a photo of the impact site, in which a star-shaped dust spot can be seen. A total of 95 grams of meteorite material was recovered, seven grams of which are now part of the university's meteorite collection.

The small stone from outer space hit the entrance area of a house on Prince Edward Island last July. The island is located in the Atlantic Ocean and forms its province. According to the broadcaster CBC, the homeowner had just started his walk with his dog. If he had been outside his house just a little longer beforehand, “the thing would probably have split me in two”, the man said. However, the impact was only recorded by the security camera. It was only a friend who pointed out to him that it was probably a meteorite, whereupon he collected the fragments.

The head of the meteorite collection at the University of Alberta then confirmed that the assumption was correct. Ten days after the impact, Chris Herd was able to examine the pieces and take a few for himself. While its arrival on Earth was unusual, the object itself is not. It is a so-called chrondrite, which are by far the most common meteorites on Earth. However, “we have never heard of their impact before," Herd told CBC. The image is “impressive”. The meteorite itself has since been christened the “Charlottetown meteorite” after the capital of Prince Edward Island.
