Ceres is in our Asteroid Belt, and is sometimes referred to as a "Planetoid". Callisto is one of Jupiter's moons, the second largest (after Ganymede) in Jupiter's orbit, and the third largest overall in the Solar System. Titan, one of Saturn's moons, is the largest moon in our system. Kepler 22b is an "exoplanet", a planet we've discovered outside of our solar system. And Proxima Centauri is a small star just over 4 light years away from our sun.

I've probably said this before but the Bootes Void is equal parts fascinating and terrifying the more you read into it. The most perplexing thing is that it only contains 60 galaxies in a space that would usually roughly have 2000 and we don't know why, the leading theory is that lots of other smaller voids joined together to create this supervoid. It's so big that if The Milky Way was in the center of it we wouldn't have known there were other galaxies until the 1960's. Definitely recommend looking up a video on it.

The ones with Indian villagers reacting to videos of the wider world are pretty cool to watch also, for me at least.

2:43 I love people who can openly admit to not knowing, and then ask. such people can learn. such people are treasures.

What makes 2 of those giant stars the most interesting to me, is that I can go outside and actually see them with my own eyes. Rigel (the big blue star) and Betelgeuse (the big orange star) are both part of the Orion constellation and easy to spot. Betelgeuse in on top and Rigel at the bottom. If you have a clear view you can actually see that Rigel has more of a blue tint and Betelgeuse is definitely more orange.

This video demonstrates size comparisons of various celestial objects that astronomers have observed in the cosmos at large. It's actually not to scale to be honest but it does give you a sense of the enormity of space. Our star (the sun) which is massive is still just a yellow dwarf main sequence star.

2:29 made me smile and laugh a little, in a good way! I’m a Brit and I’ve never heard an American say daft before, quite a common word here but not something we tend to hear on American TV shows and the like, something we watch a lot of.

I have been a subscriber of your channel for a while now. It has been fun watching your channel grow each time I watch a new video. In no time you will have 100k followers. Looking forward to that day. Please keep up the great work.

All these videos are fascinating on that channel, do more of those. Love your reactions

The very first time I saw this video was in a college class back in 2016... it literally was a new interest unlocked. I've loved astronomy ever since then its so fascinating

So I watched several of you're reaction vids tonite and I cant decide whether you're more thoughtful or more beautiful. But I know you've got a lot of both!

PLEASE DO MORE space videos. I would love to see you uncover so many of the universes hidden gems. I could see you going down the rabbit hole. There's so many interesting things to learn about space. Video suggestion: Any of "Lemino"'s space videos. High quality, articulate and well researched

Just gonna say you have the best react channel on youtube imo. Was gonna tell you about Ceres, Proxima Centauri etc. but it looks like the comments already took care of that. Side note though you could watch (or read) "The Expanse". Great show that fictionally depicts human settlement on Mars, Ceres and other asteroids and the effect it'll have on humans and the politics around it all along with a lot more. Also another show you could be interested in is "Raised By Wolves". This one has a lot more religious (fictional) undertone to it but it depicts human settlement in Kepler 22b. Both are great shows in my opinion and for different reasons.

Nice reaction. There was a video called "The Scale Of The Universe (The Universe to Quantum Foam)" that went from macro to micro, very fun. A 1950's film actually touched on this "The Incredibly Shrinking Man" very touching ending. Have a great day!

I loved that film (The shrinking man) when I was a kid, though it scared me a bit.

I've seen these videos so I know how astronomical the sizes get is mind blowing even unfathomable it makes the reaction exciting

I identify with your comment about how humbling it was to watch this. This is the sort of thing that gives perspective, reminding us of how small ours can be. "Existential" indeed. After watching this and then thinking about the vastness of the universe (and this is only what we know of), and how much of it there must be beyond what we know of, three things came to me: Star Trek, awe, and worship. I used to be into this kind of stuff when i was a kid, and seeing this arouses some of the curiosity and fascination I had back then. If I can find/make time to read, I would be interested in getting into astronomy again. Or, I think The Great Courses has an astronomy course or two; I might start there.

Thanks for always stirring the imagination with curiosity on things in your videos. Great job young lady.

What is interesting to think about is that a year on earth hasn't been the same since our solar system began and so if you wanted to be technical you could find the average of our planet's shortest revolution compared to its current and you would wind up with a light year several magnitude shorter in overall miles.

I would highly recommend Melodysheep videos. They are entertaining, informative and existential. The quality of the videos is second to none.

Sometimes I'll gaze up at the night sky observing the endless sea of distant galaxies and feel a little peeved off by the sense I'm staring in the direction of intelligent lives, some of which will be having the exact same thought but we'll never be able to communicate or even confirm the existence if each other.

I have a literary recommendation(A good place to start): Stephen Hawking’s A Brief History Of Time, and The Universe In A Nutshell. Recently Barnes and Noble put out an edition with a ton of illustrations so it makes the abstract concept brought up in the book a little easier to digest.

This never stops being fascinating. If you want more things like this to blow your mind, I highly recommend a channel called MetaBallStudios.

Astronomy has always fascinated me, just thinking about the vastness and what has never been discovered boggles the mind. I certainly missed my calling.

It is a video where I compiled all of my favorite clips from my favorite sports, and combined them with the most fitting music I could find. It took me over 8 months to finish that video, mostly because I kept adding new and better clips. That video epitomizes my greatest interests. I would be thrilled to see you react to it.

Ceres is a dwarf planet that does exist in our solar system but is too small to be considered a planet, Kepler 22b isn't part of our solar system but a earthlike planet about 600 lightyears from our solar system. Proxima centauri is the closest star to our own and Sirius A is the brightest star in the night sky. The rest of these objects, that probably goes without saying, are not part of our solar system either.

Nice Reaction. You can also react to Roko's basilisk, it is an interesting theory about the future of AI.

You mentioned existentialist stuff. Thoughts, dread, etc. If you want to go a little bit mad (assuming you aren't already familiar) there's always the Many Worlds Hypothesis (Everett Interpretation), the whole idea that the reality we're living in now is only one of countless realities and universes in an infinite cosmos. Brian Greene is the guy you want to look for (again, if you haven't already). He explains a lot of this stuff - alternate universes, time travel, all that sort of thing. That's one existentialist rabbit hole you might never come out of.

.....MIND BLOWN!!!!!

Correct. The red objects with Uy Scuti are stars. And the dark spots are black holes.

The 4 objects known as Ceres, Pallas, Vesta, and Hygeia were at one point taught as planets when they were newly discovered, but as more planets were found farther out and since they all kinda sorta shared an orbital distance, they got "demoted" to a newly created category of space object called "asteroids" (meaning "star-like" becuz they were so small they appeared as a point of light in an image, just like a star, but.. not a star). Ceres has since been "promoted" to the "dwarf planet" category along with Pluto, Sedna, Eris, Makemake, and so on. Callisto is one of the 4 "Galilean Moons" of Jupiter, along with Ganymede, Europa, and Io. Kepler 22b is an exo-planets, only recently discovered, so it likely isn't really taught in schools at all. Proxima Centauri is a red dwarf star that is so dim that it isn't actually visible to the naked eye. Despite that, it is currently the closest star to our solar system at a distance of 4.24 light years. It orbits the binary star pair that we call Alpha Centauri (making the whole thing a trinary system, obviously), which is a shade farther out at about 4.396 LY. Sirius is also called "the dog star" because it's in the "Canis Major" (Big Dog) constellation in the southern hemisphere. It is the brightest star in the sky (ignoring the Sun, obvs ;-) ). Vega is the brightest star in the constellation of Libra. Arcturus is the brightest northern hemisphere star and has served mankind as a navigational beacon for milennia. it's in the constellation of Bootes, which also has the Bootes Void in that part of the sky too. Rigel and Betelgeuse are both in the constellation of Orion, on opposite corners. And yes, the Orion Nebula sits within this constellation also, but just below Orion's belt. The other red supergiants featured are dimmer and not really well known, but tend to be included in videos like this due to their sheer size.

Have you ever watched the "Metric Paper" video, which is not really about paper but a voyage from our scale to the smallest and then to the biggest things, there are? I love it and so do my kids.

Hello,was wondering if you’re still going to do the journey to the end of the universe by cool worlds channel.thanks.

Voyager I was launched over 45 years ago, was further than Pluto's orbit over 30 years ago, and is currently the most distant human-made object. NASA estimates that Voyager will be finally out of our solar system in 15,000 to 28,000 years (we're still not sure how far out the Oort cloud extends so the estimates vary greatly). And this is one of the hundreds of billions of solar systems in our galaxy alone. The vastness of our universe is absolutely mindblowing once you start looking at what little we know of it.

I want to recommend the channel 'History of the Universe' for some theoretical physics, particle physics and astronomy stuff since we're going into space now.

5:53 yep. the first time I saw one of your vids ;)

Vega is where the transmissions came from in the 1997 movie Contact starring Jodie Foster, written by Carl Sagan

Ceres is a protoplanet, Kepler-22b is an exoplanet orbiting Kepler-22, a star very similar to our sun (97% it’s size) about 600 light-years away. Proxima Centauri is the star closest to us apart from our sun, about 4.2 light-years away. It’s a tiny and cold red star.

The Ones that show the "Textures" are planets in our Solar System (Because they're reflecting the Sun's light). The Planets that are "on Fire" are Stars outside our System (we see them because they're Creating their own light (and, as you see) are MUCH Bigger than our Sun. Astronomy is a fun hobby! GREAT Reaction! They have several KZread videos that show "Our Visible Universe" and all the Planets within... Mind Boggling! Are we alone? You have to question that after watching them!

i remember that our Geography teacher told us the news, that now (~2007) we have one more planet in our solar system, which was recently discovered.

Enter the Void is a crazy movie.

I remember Callisto being one of the several moons that orbit Jupiter. I played this Space game in middle school and many moons had those names like “Kepler 22” and some had names that also came from mythology, like Callisto.

Kepler 22b is a planet.

What is really crazy is that the sheer scale of the universe compared to us is equaled by the sheer scale of us compared to sub-atomic particles. You could legitimately play the whole video back zooming in instead of out just as far - and at the end you'd just have a planck unit of solid blackness filling the screen with zero information.

the kind of light a star emits is key to what kind of star it is, and it's mass density, then we can look at other celestial objects near it and their movement around the star then we can calculate their gravity intensity per unit distance, from this we can know exactly how massive the star is. just like the discovery of neptune.

This nebula is the middle star in the sword. -Omega Centauri is a globular cluster visible form the Southern Hemisphere and low parts of the Northern.

Something astronomy-related I could recommend is a video by Professor Dave Explains titled "Life and Death of Stars". Gives a nice insight into these magical objects whose light we can see from these mind-bogglingly huge distances. Or, I guess, could see, the sky in my city is pitch-black thanks to enormous amounts of light pollution. P. S. Muse is life 😄

If you haven't watched "Black Hole vs Stars MASS AND SIZES" yet, it's a pretty decent video about just how much mass is within most of these black holes.

The nebula they were showing are where large clouds of gas and dust are illuminated by dead stars that sent shockwaves outwards as they died. Usually leaving behind a white dwarf the is white hot but very small. Also illuminated by new stars that formed from the resulting waves travelling through the dust. Those new stars are seeded with heavier elements than can form during a normal nuclear fusion in a star, such as uranium. The orion nebula is visible from most places once you find the constellation Orion. It is beautiful with a telescope. Hubble formed a 3D image of it during it's long observations of it.

You have to watch "The Expanse" lots of Ceres and Ganymenede stuff.

nebulae are cool; the Orion nebula can be seen just with bird watching type binoculars (8x40, 7x50, 10x50, etc). you might find a video of "the messier objects" interesting, named after 1700s comet hunter Charles Messier, who was the first to make a list of DSOs (galaxies, nebula, and star clusters) so people would stop reporting them as comets ... the messier objects became a common starting point for amateur astronomers since most of the easiest to find are on it (I've found all 110 messier objects with binoculars/telescopes, it's a fun adventure)

size comparison too all planets and suns we have seen

You should watch "VFX Artist Reveals the True Scale of the Universe" they do it on a scale that makes more sense and blows my mind even further.

yeah they added all known planets (stars) of the universe for that comparison

I saw that long ago just for the track ,you got it going ,see Arturus?

I'm a huge astronomy nerd, so I'll try to answer all of your questions here. :) 2:02 Ceres is a dwarf planet, like Pluto, but there are so many dwarf planets that have been discovered in the last few decades that they usually aren't all taught. Callisto is a moon of Jupiter; there might be more moons than dwarf planets in our solar system. Kepler 22b is an exoplanet, meaning it's a planet in another solar system. And Proxima Centauri is another star altogether, so not part of our solar system either (though it is the closest star to our Sun, and is part of the triple-star system of Alpha Centauri). 3:04 Not a question, but I can't help pointing out that the Sun is white, not yellow. We only think of it as yellow because it looks that way when viewed during dawn/dusk (when the sunlight passes through more atmosphere and has more blue light filtered out). 3:50 All the stars with "proper names" (Rigel, Arcturus, Betelgeuse, etc.) can be seen with the naked eye at night - if you know where to look. 4:18 Yup, that's a black hole. Specifically, a *supermassive* black hole at the centre of another galaxy. And TON 618 is the largest black hole known.

you sir are absolutely right ( im a huge astronomy nerd too :D )

I would imagine it's high time for people who teach kids Astronomy to start including a lot more than the 8 planets of the Solar System. Our knowledge is much greater than it was around 25-30 years ago. It's a great time to be an astronomer.

You should watch Star Talk .

"neptune and uranus are relatively close in size..." 😂
