So the solar system was formed about four and a half billion years ago. It's this great big swirling cloud of gas and dust. And around this time after the planets were formed, there were loads of these asteroids basically whizzing about all over the place. And lots of them were bombarding the Earth. So there was ample opportunity for these ingredients to be carried to us.

In that case, there could be other planets in which the same thing has happened. Yeah, that's right. So, you know, Earth wasn't the only place being bombarded with asteroids. These asteroids were striking planets all over the place. And this offers up a really interesting question, you know.

Is there something really unique about the Earth and this particular set of circumstances which sparked life, you know, when life began? Or... Did life happen? Did it begin on other planets, moons of planets perhaps too, and then fizzled out? Or is it still there and we just don't know about it? So it's really a very intriguing finding and there's so much research still to do on Bennu.

They've only just literally been sort of touching the surface of these grains. There's loads more to understand but also loads of places to visit too to kind of see what's happening there. Rebecca Murrell.
