Ryugu asteroid: It came from the outer solar system, say scientists

Scientists examining samples from the asteroid Ryugu retrieved by the Japanese Hayabusa-2 probe have concluded that Ryugu is a drifter from the outer solar system. The results, published in Nature Astronomy, come after just over a year of initial analysis conducted by institutes and universities across Japan, the UK, and USA …

That's what they want us to think.

Yes, the alien in me is working hard to convince you all. The more controversy, the more we can work unobserved and hide that we are already here.

No, I wont get that probe out of your backside. Don't scratch, get used to it. We used asteroid water to clean it, honest.

Given where it went cleanliness was the least of my concerns.

...was...concern...

Glad to hear it no longer is.

The theories described in the story have been around for very many years now, there's a lot of evidence that they might be correct and virtually no evidence that the concepts are wrong. The evidence from the Ryugu asteroid does tend to backup the concepts.

That sounds just like something *they* would say.

"Asteroids like it (C-type asteroids) could well have been one of the sources of Earth's water"

Given that there are about 1,386,000,000 cubic kilometers of water on Earth, maybe C-type asteroids didn't contribute that much of it - unless a huge number of such asteroids hit the Earth, and if so where are they all?

Under the water, obviously?...

And Europa has more than twice as much. There's a lot of water in the outer solar system.

Hence why we were told not to attempt a landing there - nothing solid to land on.

Earth keeps doing this thing called subduction which means most of the surface is quite young. This means that any evidence of those impacts is long gone.

I know, it's stupid and someone should stop it, but nevertheless it is still happening.

Elephant in the room

Why nobody is asking anything how the Japanese asteroid Ryugu found itself outside of the solar system in the first place?

How did they do it?

Re: Elephant in the room

Go study the history of the solar system, how it was probably originally created and the events that likely happened, theories based on what we see floating around today, and influenced by what we can see elsewhere in our galaxy. There virtually no evidence that the current view of our solar system life is wrong.

It came from Outer Space

And this is how the message ran.....
