NASA found something mysterious at the edge of our solar system

The Kuiper Belt is a donut-shaped object at the edge of our solar system. Scientists using data from the New Horizons spacecraft found something weird about it -- there might be two Kuiper Belts out there. Learn more about how the Kuiper Belt formed and how it differs from the Oort Cloud in this video.

"NASA found something mysterious at the edge of our solar system"...millions upon millions of socks. But...none of them match.

Since the Oort cloud may extend almost halfway to the nearest stars, and since it does NOT conform to the flat plane of the solar system, and since other stars may have equivalents to the Oort cloud, could some members of the Oort cloud be captured from other stars? If so, they might be much older than our solar system. Good video!

This simple plain description of the outer solar system really helps
Yes, we maybe a weirdly shaped system, with our gas giants in odd places, I like it!

I started to look up an image on the internet that would show me the Opik-Oort Cloud vs. the Kuiper belt and before I was successful this video beat me to it at 5:57. Well done Ad Astra, and I think I'll subscribe to this channel!

The TLDR: the Pluto probe went through some dust.

It's amazing that Voyager 1 survived the belt(s). Now that it's back online, maybe it can take a photo looking back!

[ARWest-bpyb]

We still have a lot to learn about the universe!👍👍

[thomasbeach]

Thank You for explaining all of this to me in a way that I can understand.

I have always been taught the Oort Cloud is the outer portion of the Solar system. The edge that stretches out to halfway to the next star. Part of it in, part of it out of Sol's influence.

Also, I believe your timescale for Voyager reaching the Oort Cloud is way too small. Three hundred years or so, I believe.

oort cloud: oort

I once heard an estimate of thousands of dwarf planets in the Oort cloud from someone fairly famous.. I think they were one of the big names in the pluto debate. Has that opinion fallen out of favour?

[MichaelLloydMobile]

Interesting information.
Solar systems are much more complex than we originally thought.

[jasonkinzie]

Interesting video! One nitpick. Voyager 1 will reach the inner part of the Oort Cloud, (if it exists), in around 300 years not 30.

[henrytjernlund]

Maybe Oort clouds in interstellar space is an answer to the Fermi Paradox making it promlematic to near light speed travel causing high tech aliens to move out into cleaner intergalactic space.

[dustyk]

The real question is how much small matter is out there between stars? I think I’ve heard it’s estimated there’s three times more matter than can be accounted for in stars and planets that makes up our galaxy to account for how it holds together. Dark Matter because all that stuff is far from stellar light? Is that what makes super distant stars twinkle as they eclipse them?

[davidtindell]

thank you! Now we know where 'Orchs' come from !

[Hollywoodhouse]

How did both voyage 1&2 get threw the outer one??

[_TravelWithLove]

Thank you for sharing your insights and knowledge filled videos !! Intelligent and scientific stuff !! Excellent !!

Greetings from California … I wish you and folks good health, success and happiness !! Much Love ✌️😎💕

Without Jupiter, we wouldn't be here.

[AEFisch]

? The outer planets are Gaseous where the kuiper belt and objects (pluto) are rocky. I'm not understanding the relationship?
