Earth gets constantly bombarded with space rocks from outer space, but luckily for us, most of them get totally obliterated in the atmosphere. And even bigger luck we humans have considering the presence of Jupiter in our solar system. The gas giant is capable of attracting most of the asteroids that could pose a threat to our planet.
Chondrules are mysterious chunks of material found in a lot of meteorites that have crashed into Earth. After a new study, scientists think they discovered where these chondrules belong to.
Proto-planets covered in lava
The new theory claims that proto-planets covered in lava have incinerated asteroids as they got close, and further melting the chondrules into them. The scientists involved also believe that chondrule-packed chondrites can make up 86 percent of the meteorites that smash into Earth.
Researcher Rhian Jones from the University of Manchester stated:
Chondrule formation is just a really thorny problem,
So anytime somebody comes up with something completely different it’s very welcome, because we don’t have the answer.
A research reveals that every year, our planet is hit by around 6100 meteors that are large enough to reach the ground. This also means that about 17 meteors are visiting our planet every day. Luckily for us, the vast majority of the space rocks fall unnoticed in uninhabited areas. But the more unpleasant news is that many scientists are convinced that an asteroid large enough to exterminate all life forms will visit Earth again some day. It happened before about 60 million years ago when the dinosaurs got extinct. Although those creatures lived for millions of years (230 to 65 million years ago, in the Mesozoic Era), they didn’t invent any tools for deflecting or destroying large asteroids.
The research about the chondrules was presented at the American Astronomical Society’s meeting.
