It was 11:47 p.m. Paris time when the Breton sky lit up. A green ray crossed the region, visible from both sides of the Channel. In total, 241 people gave precise accounts of the event, but hundreds of thousands were treated to this spectacle from the sky.
The meteorite could have crashed not far from the town of Morlaix, but for the moment only estimates of its speed and altitude allow to give it a trajectory, still very uncertain.

Falling meteorites: a risk for the Earth?
It is common to see meteorites passed in the terrestrial sky, it is moreover the very principle of shooting stars that we like so much to observe. But meteorites like the one that has just pierced the Breton sky are much more worrying. Closer, they can fall directly to Earth or destroy themselves a few kilometers above sea level, in either case, the shock wave created by the explosion would potentially be capable of razing a village, a city, or most of it. planet, as was the case during the extinction of the dinosaurs.
So how do we know if the heavens have in store for us such a dire fate as our Mesozoic predecessors?
Don’t panic, the risk of imminent death from a falling meteorite is still far away. Especially since the human species has a major advantage over tyrannosaurs, its knowledge of the sky. Today, the biggest space agencies take turns staring at the sky in search of a piece of cosmic pebble with a trajectory a little too close to the Earth. And according to NASA estimates, we are quiet at least for 100 see 200 years. Obviously, this surveillance does not prevent some surprises: with its small size, the Breton meteorite has indeed passed through the radars of space observers.
If phenomena like the one that has just occurred in the French West are likely to recur in the months or years to come, it should not present any danger to us on Earth. These meteorites, although very bright and impressive are generally harmless and if they do not destroy themselves in the atmosphere (as was the case this Sunday) they mostly end their course in the ocean.
