But it's really just the last few decades that researchers reached a broad consensus that rocks fall from space.

Before then, people didn't even know how the craters on the moon were formed.

And the debate's been going on for a long time, like all the way back to the early 1600s.

That is a long time to be debating this.

At least now we've established that the craters on the moon and the craters on the Earth are real.

They're from space rocks.

And we can still find remnants of these space rocks that have collided with Earth here, right?

There's traces.

There's evidence that that happened.

Yeah, they're pretty much everywhere.

And two thirds of the ones collected by researchers come from Antarctica because they're really obvious to spot on top of those giant sheets of ice.

That makes sense.

Yeah.

But how do you know that the thing you're picking up is a meteorite, that it came from space and it's not just some random rock?

Well, first, rocks don't really come up from the bottom of the glacier.

So if there's a rock lying on top of the ice, it's probably a meteorite.

Sure.

Second, researchers can use powerful magnets to detect some of them, especially the ones that are made up of mostly iron.

Hmm.

which actually you and I can do on a much smaller scale at home.
