There is lots of carbon and water in samples that Osiris REx took from Asteroid Bennu.
There is lots of carbon and water in samples that Osiris REx took from Asteroid Bennu. This is an important thing. If we search for the origin of life. Asteroid Bennu is about 4,5 billion years old. Bennu's location is at a longer distance from the Sun than the asteroid where the Japanese took their samples to Earth. That means minerals on Bennu faced less electromagnetic radiation and other changes.
Sometimes researchers think. Bennu might be part of some protoplanet that some catastrophe destroyed in the early solar system.
There are also remnants of clay. That means the protoplanet might have water on its shell or atmosphere. The clay could form when that protoplanet is destroyed by gravity or impact.
In that process, water impacts with minerals that fly away from that destroying protoplanets. The effect raised the speed of those particles to a hypersonic level.
During that process, some effect like impact energy transforms the planet into an asteroid cloud. Hot and liquid minerals interacted with vapor in that protoplanet's atmosphere forming the clay.
In that scenario, there was no liquid water on that extremely hot protoplanet that formed Bennu. The water was vapor that formed the clay in seconds. And the asteroid Bennu is one of the remnants of that planet.
And when some catastrophe destroyed that planet. Vapor in its atmosphere interacts with melted minerals. The thing that destroyed the protoplanet was the impact of another protoplanet. Or maybe its spin's speed was so high that centripetal forces destroyed that planet, which was liquid magma with vapor in its atmosphere.
An artist's depiction of the hypothetical impact of a planet. Like Theia and the Earth". There is the possibility that Bennu formed in that kind of impact. (Wikipedia.com/Theia (planet))But in wild vision that protoplanet could have a solid shell. And then some impact destroyed it. There is lots of carbon in that asteroid. That element is vital for life forms. Bennu samples tell that it's possible that in the young solar system was at least one planet more than the Earth that could form lifeforms.
But that planet is lost in impact or some gravitational effect before life can begin or it got a solid shell. So the history of that planet was short. And maybe it stayed as a planetoid. The early ages in the solar system were violent, and many planets and moons faced their fate in cosmic catastrophes.
Theia was a protoplanet that impacted Earth forming the Moon.
If the Moon formed at the same side, where Theia impacted. It got its beginning from the giant droplet.
If the Moon formed the opposite side from Theia's impact. It formed from the giant shockwave that traveled through the Earth.
Also, Earth impacted another planet called Theia in its younghood. That other protoplanet's remnants remain in Earth's magma. Sometimes is speculated that the gravity hole in the Indian Ocean has something to do with particles forming clouds in magma. The position of that cloud is the thing that causes the gravity anomaly. And there is a possibility that those particles are from Theia.
Another interesting thing is the missing continent that remains at the Pacific bottom near New Zealand. That area is called Zealand. That lost continent could have lots of material from Theia. And if that material was heavier than other rock. It means it falls to the mantle.
But Theia completely vanished in that catastrophe. During that impact Earth's shell was liquid. And that could save our planet from turning into an asteroid cloud. The impact with another protoplanet formed the Moon or at least part of it.
When the large, almost small planet-size asteroid impacted young Earth before its shell was solid. Theia sends material to the orbital trajectory. And the question is: did our moon form on the same side where Theia impacted? In that case, Theia sends a giant droplet to space. And that droplet turned to the Moon. In another vision, Theia sent a giant shockwave through the Earth, and the Moon formed the opposite side to Theia's impact.
