Have you ever considered the odds of a fireball crashing through your roof and onto your pillow while you were sleeping?

Peter Brown has.

B次元官网网址淭he chances of a meteorite big enough to penetrate a roof and hit a bed are about one and 100 billion per year,B次元官网网址� said Brown in the wake of exactly that situation happening to a sleeping Ruth Hamilton in Golden on Oct. 3.

Brown is Canada Research Chair at OntarioB次元官网网址檚 Western University and has been a researcher in this field for 30 years. He said an opportunity like the one in Golden only presents itself so often.

B次元官网网址淲hen we first heard this story we were pretty surprised, but also pretty convinced that it was a meteorite and we certainly had a pretty good idea of the fireball that was related to it,B次元官网网址� he said.

Despite the long odds, itB次元官网网址檚 not the first time this has happened in 2021, with Brown citing a similar incident in Indonesia this past January where a meteor also came through a roof and hit a bed.

Meteorites offer an important look into the unknown of space, as theyB次元官网网址檙e the only material available on earth that comes from, well, not earth. Researchers are hoping that Golden area residents can help them track the route taken by this fireball. Anyone with dashcam footage or video of the fireball are encouraged to reach out.

B次元官网网址淚t helps us reconstruct the past in the atmosphere and the orbit the object took and that will then help us put this meteorite in context,B次元官网网址漵aid Brown. B次元官网网址淯ltimately, weB次元官网网址檙e trying to understand how the solar system and planets formed.B次元官网网址�

Brown says that if researchers are able to reconstruct an orbit pre-impact from the object, it can offer a clue as to where in the asteroid belt the rock came from. Detailed analysis on the ground can let them know the spatial context of the object, but not about itB次元官网网址檚 orbit.

Brown says that while thereB次元官网网址檚 tens of thousands of meteorites, there are only orbits on a few dozen.

Brown says itB次元官网网址檚 also not a shock that the rock did not burn the bed when it landed, as meteors stop being luminous at about 18-20 kilometres of altitude, giving them plenty of time to cool off in the chilly upper atmosphere.

Brown says Golden residents, particularly those in the north end of town, should keep their eyes peeled for similar meteorites, as thereB次元官网网址檚 a good chance further debris may be scattered.

Alan Hildebrand, a planetary scientist in the Department of Geoscience at the University of Calgary and his collaborators had done a preliminary fireball trajectory solution, and had predicted the location of its fall. They were on the ground in Golden this weekend searching for more, said Hamilton.

While the search continues around Golden, Hamilton says sheB次元官网网址檚 had enough of the excitement.

B次元官网网址淚B次元官网网址檓 pretty much behind the scenes at this point. I live a quiet life and itB次元官网网址檚 been overwhelming,B次元官网网址� she said B次元官网网址淗opefully someone else comes along and takes the focus away from me.B次元官网网址�

Hamilton has since loaned the rock to Western, saying that they personally came to pick it up and that they will be returning it on Nov. 30, after which sheB次元官网网址檚 not quite sure yet what she will do.

B次元官网网址淚tB次元官网网址檚 got its own escort at this point,B次元官网网址� remarked Hamilton. B次元官网网址淚t just speaks to its importance and its scientific value.B次元官网网址�
