For the other Astronuts out there

Oh, all right...since it's you...

Unfortunately I read that a massive asteroid/mass can come closer behind Jupiter's cover and we only see it once it comes out of the 'shade'. So we cannot see them from far away necessarily. Glad to know that.

 

Jupiter acts as a goal keeper for the inner planets...so much mass it attracts objects to itself...we owe a lot to Jupiter.

 

Well, that does help,actually. I just saw a document saying things can just "appear" from behind Jupiter but never thought about the mass it has.

 

Never thought this could be true...

The dwarf planet Pluto has five natural satellites. In order of distance from Pluto, they are Charon, Styx, Nix, Kerberos, and Hydra.[2] Charon, the largest of the five moons, is mutually tidally locked with Pluto, and is massive enough that Pluto–Charon is sometimes considered a double dwarf planet.

Moons of Pluto

 

Didn't know that about Pluto.

 

O-kay then...
"Blobs of rock lurking deep inside the planet could be the last remaining pieces of Theia, an early world that collided with Earth billions of years ago, a new study claims.
The moon is thought to have formed from a 'giant impact' early in the evolution of the solar system when a Mars-sized planet called Theia collided with the Earth.
Deep within the Earth are a number of strange, huge blobs of dense rock called large low-shear-velocity provinces (LLSVPs) and a team from Arizona State University believe these massive regions may be parts of that long-destroyed proto-world.
One of these LLSVPs is buried under Africa and another deep below the Pacific Ocean, both so large they are involved with the weakening of Earth's magnetic field.
Qian Yuan, author of this theory, suggests the blobs, which 'straddle the Earth's core like headphones' are denser and chemically different to the rock surrounding them."

‘Thought to...’ ‘suggests’...

Not fact yet.

 

I would not be surprised if there were other further planets than Pluto.

 

See good old British cynicism's rubbing off on you.

 

You mean Scottish cynicism...beats British cynicism any day...

Taught 'im everything he knew.

 

I still believe this is going to have a large impact on what we know and what we'll learn;

Engineers working on NASA’s James Webb Space Telescope have successfully folded and packed its sunshield for its upcoming million-mile (roughly 1.5 million kilometer) journey, which begins later this year.

 

Yep. Hubble revealed some amazing stuff, so roll on this one being deployed.
