What also fascinates me about Earth is the variation of terrain. We got dry deserts, wet rainforests, deep blue oceans, high monstrous mountains, etc. It's like multiple other worlds into one! Every other rocky planet we know of doesn't have features like our own home. The vastness, overwhelming size of our universe tends to make us forget about the interesting & beautiful features of our own world.
I often think about that. We also have hail, snow, rain, rainbows, lightning, sun, a range of cloud types, seasons, day and night cycle, rivers, large streams, seas, oceans,…. There is so much variety in the „dead“ nature alone, it’s truly stunning
But at the same time, the vastness of our universe, and even our own solar system, tends to make us forget that we may not have the most interesting & beautiful features. We may not be the only planet with such variations in terrain and weather. And, the features that we do have, pale in comparison to the features beyond our basic comprehension of other worlds even within our own Solar System and elsewhere. Titan has seas of liquid methane, Europa and Enceladus have global oceans underground which could harbor life. That is just within our own solar system. Janssen, or 55 Cancri E in the 55 Cancri System, could be made up of nearly 1/3rd of it's mass in diamonds. And, there are also some speculations that there are planets outside of our own solar system better equipped for life than even Earth, such as KOI 5715.01.
Earth really just feels like by far the one of the coolest planets if you look at it without the bias that we live here. Listening to people talk about it, it really sounds interesting
Hey man. Someone has straight up ripped off one of your videos on Pluto. They've basically just re-uploaded your video with an AI voice over reading the same script. The channel is called Beyond The Cosmos.
This is endemic on RUclips, but RUclips don't seem to want to do anything about it as it still generates ad revenue for them. Kyle Hill did an interesting video on the topic about a year ago called "RUclips’s Science Scam Crisis", if you're interested to learn more.
Hello Alex, you are absolutely right, this planet has so much wonder to offer. With the astronomy and space exploration it is amazing to learn about planets made of diamonds, or places where molten iron rains down, but after the initial surprise and novelty of such other worlds wears off, it is clear that the dynamics, diversity, natural processes and just beauty of this planet stands out. You said it - "Will anything in universe ever be so beautiful and welcoming as this, our home planet?" I love this so much! Also, I am really glad, that you've mentioned that plate tectonics is rare and unique and what it does for life. I haven't heard it often before. After watching Anton Petrov's video yesterday about the fact that plate tectonics may be the reason why the Fermi paradox is a thing, I'm happy to hear about its importance and uniqueness from another source. Thank you so much for all you bring to this world, Alex. Amazing education but also reminder of beauty and gratefulness!
I learned all this stuff in Meteorology school, and I need daily refresher lessons to remember it all. Same is true for many of my colleagues. Thank you, Alex! 😊
This video is very beautifully made and created, It reminds us how much beauty, how dynamic and important earth to us. But many people on earth don't appreciate earth that much, like Carl Sagan said "We succeeded in taking that picture, and, if you look at it, you see a dot. That's here. That's home. That's us. On it, everyone you ever heard of, every human being who ever lived, lived out their lives"
thank you well presented - in my time in the navy and then travels over 20 years i have been amazed at the differences and similarities from north to south / east to west in geograpy and people - thank you!
Imagine being an eternal conciousness roaming the cosmos for eternity alone. Seeing nothing (other concious life), knowing nothing, bored, lost, utterly alone. Every gakaxy, every star you visit.....nothing. Then one day in that eternity of loneliness, you discover Earth and think to yourself 'alas i have finally found heaven in a universe of hell'
An eternal consciousness? Oh, you must mean God. Let me tell ya, he didn't create all this to leave it 99.999~% void of life... I'm afraid life is everywhere in the universe, and God put it there for His pleasure...
@@Quickened1you say "god is the creator" and equate god to the eternal consciousness, yet the eternal consciousness "discovers earth", so the eternal consciousness is not god
This is why a colony on Mars will never work. The first people who are born on Mars will learn how amazing Earth is and curse the people who forced them to be born on Mars. Then they'll just end up coming back here.
I’m pretty sure they wouldn’t stay on Mars forever. We’d probably do something similar to the ISS where people go there for a few months or longer and then return to Earth. If not, maybe they live on Mars but are allowed to visit Earth every now and then and people on Earth could visit Mars every now and then as well. Or maybe reproduction won’t be allowed on Mars until we can find some way to colonize it and make it Earth-like (which comes with its own set of problems). But there are many other problems with building/starting a colony on Mars that people are actively trying to solve. Mother nature loves to throw challenges at us but eventually we find a way to overcome them even if it takes thousands of years to do so.
I seems without burrowing deep underground, humans would receive a lethal dose of cosmic radiation on Mars in a few years. Though that's enough time to get homesick.
Mars will not be settled to live there. Mars will be settled for mining and research, and all people that will go there will go by an incentive. Also, by that point travel between earth and mars will only take some weeks, if youre born there and want to move to earth it will be no problem.
@@tylerwright3950 Mars doesnt have this weak of a gravity, while they certainly wouldnt be top athletes for a while on earth, they would be fine and over time muscles would build up.

Great series Alex! Really enjoyed all the detail and I noticed all the extra time put into each video. Thanks Alex and the Astrum Team. Thanks to the Patreons.
Consider the three great advances that got us out of the caves and into the cities. 1) The harnessing of fire. 2) The invention of the wheel. 3) The creation of the first Tandoori Mixed Grill. Cheers
I'm glad you mentioned tidal forces acting on the crust, not just the water. Tidal force acts on everything, it's just that the water moves because it can, but the thin layer of rock is under enormous strain because it can't move easily - a strain that changes direction four times a day. The planet is being constantly massaged and I believe this is the cause of the grumbling and groaning, the thousands of tiny earthquakes that occur each day. Convection currents in the mantle probably cause the overall directional movement, but as you say, it's likely that tidal forces enable or enhance this movement by constantly nudging it. On the time scale of plate tectonics, it'd be like a vibration.
Oh how I wish I were this innocent and naive, believing the French could be explained. No. They are an anomaly, a glitch. One that the lead dev God (capital G) couldn't solve so just claimed it was a feature.
@ldubt4494 so, there's actually the possibility of living in the upper atmosphere of Venus, above the sulfuric acid clouds. It's potentially dense enough that it might be very plausible to build floating settlements. Or so I've read.
Pockets of intelligence that are rapidly evaporating, thus concentrating the intelligence in an ever diminishing number of people. This is very apparent in the US.
I love the ambiguity in the original comment: It doesn't actually say whether Earth has or doesn't have intelligent life. :D But on a serious and sobering note, scientists have recently learned how prevalent tyre dust is, and that the particles are small enough to slip through the blood-brain barrier, though we don't yet know what it might do to the brain. However, there's an association between lack of intelligence and petty crime, and I can't help noticing that petty crime is a far bigger problem in and near urban areas. But no part of Earth's surface is without tyre dust, and over 50% of the microplastics in the oceans have turned out to be tyre dust. I love cars, but there's increasing evidence that they're amongst the stupidest things humans have ever created.
I think Pumbaa said it best. "home is where your rump rests" Home is where you exist with (relative) safety and security as well as friends and possibly family.
One thing that intrigues me is how the Earth has a 23 degree tilt. Perfect might be 22 1/2 degrees, as it exactly regulates a balanced set of extremes. 23, though, allows a couple days for weather patterns to minutely dwell, which creates a tiny amount of chaos to occur, helping create near equal sustainable rainfall and moderate air pressures(obviously not the soul reason for this but it helps).
As for nearby exoplanets, from all that I have read, and with a little statistical guesswork, within a 10 light year radius, there should be 5-15 habitable worlds around mostly red, orange, and yellow dwarf stars, and maybe 1 supermoon around a brown dwarf or a super Jupiter. Farther out, this proportion, relative to volume of space and density of stars, should be about the same.
Just the right amount of chaos. I like that. :) @@bryanbryan2968 Habitability requires so many factors to be just right that it's hard to even find what they all are. One which gets me is having the right amount of water. For all that we say Earth's oceans are vast, the science has found that we should have far more water. The Earth's surface was once covered in an ocean many miles deep. The search for a mechanism by which this excess water disappeared concluded with the discovery that a certain isotope of aluminium would have had the right energy output to boil off that much water and the right half-life to have decayed to the isotope ratio we now see. So maybe there are 5-15 worlds of a comfortable temperature within 10 light years, but many of them might be flooded to such a depth, they have no stable areas which aren't under pressure far higher than the bottom of Earth's oceans.
@@Scott-i9v2s Why? We only suffer due to human mismanagement and misrule. For instance, there have been entire societies which were non-violent and didn't overbreed. Arguments to the contrary are prime examples of propaganda in support of misrule. Having been alive for 50 years and having paid attention to older people when I was little, I can entirely believe the World Health Organization when they said, before COVID-19, "We're the sickest we've ever been." Propagandists answer this by questioning the meaning of the word "disease"; it's disgusting to hear! And I have reason to believe that disease is connected with overpopulation. Ugh! That's enough of problems. I could write a lot more, listing problems and evidence, but the birds are singing on this bright morning and I've got to get myself a tasty breakfast. ;) I'm hoping for God's Kingdom to end the mismanagement. There is evidence it's real.
The green color is due to molecular oxygen emitting between 500-550 nm. The atomic oxygen has two bright lines at 777 nm and 844 nm. So, they contribute to red glow. Nitrogen molecule dominates the magenta glow (300-400 nm)
Can we add having a semi molten core, creating a magnetic field, and a large enough moon to cause tides, and an ozone layer to the list of criteria required of a planet to be able to sustain life?
An amazing video, reminding us of the beauty of OUR Home. I hope you hear the genuine appreciaton and respect from your viewers, disregarding the trolls. Unfortunately, they are a sign that your work has achieved a certain level of recognition and status, fwiw. Thank you 💜🌍🌎🌏✊🍀
5:00 this is so crazy but im about 99.99% sure that I worked at this apartment complex. Everything about it looks exactly the same, seeing this just about threw me out of my chair once I saw it. Im almost certain. I worked there as an apartment maintenance technician back then.
Your third-person description of the Earth, as a celestial body, is quite delightful. I'm known as a bit of space nerd amongst my colleagues and they are often surprised that Earth is my favourite planet and by my reasoning,...it's where I'm from! =) Also I reckon it's the best looking planet in our Solar System
3:58 A year is actually 365.2425 days long. Every four hundred years, an additional leap day is added. For instance, 1600 and 2000, was a leap year, while 1900 or 1800 or 1700 was not. This is also not the perfect value either, it is just that the Gregorian calendar which most of us use, pretends that the year is a bit simpler.
These scientists and ancient astronomers from a couple thousand years ago were just amazing. Goes to show you, for as long as humans have been around, there has always been bright, innovative people.
9:22 🎶 The days are longer. The nights are shorter. The sun is shining. It’s noticeably warmer. Summer! Every single moment is worth its weight in gold. Summer! It’s like the world’s best story and it’s waiting to be told! 🎶
I'm mostly impressed with the substantiations in this video of my own late realizations that the entire cosmos seems to adhere to some divine plan of perfection and direction towards evolution based on a predetermined paradym of guidance from both the ultimate combined creative source and the variety of imaginative consciousness projected by sentient beings who just so hold the abilities of the imagination concepts
"Keeping time can be more complicated than you thought" this is exactly correct. I didnt realize how little I knew about time until I began studying for a world I'm creating. The thing I thought would take a couple hours at most to study sucked me into a 2 month rabbit hole...and I may be more lost now than I was in the beginning, lmffao.
03:56. This is incorrect. The solar (tropical) year is 365 days 5 hours 48 minutes and 46 seconds, or 365.2422 days. The Julian calendar (after Julius Caesar) had 365.25 days and a leap year every four years, which by the 16th century resulted in a noticeable discrepancy between the calendar and the actual solstices and equinoxes, which was solved by Pope Gregory XIII in 1582. We don't have a leap year every 4 years anymore, but a Gregorian calendar.
Could you please do a video on what happens, and the timeframe involved, when the Moon finally pulls away from the Earth? I know it would be hypothetical because no one really knows what will happen, but that would be a very interesting video indeed! Thanks, Alex!
Also most unappreciated humanity's single most important resource. The irony that hits me when realizing we're ruining it on purpose, in a race of who's gonna get biggest pile of pieces of paper that has no other value to the whole system, except the one we decided it has. (Even tho most of it is now-days in digital form). But the hope is in belief; that it wasn't a chance but intentional design of the whole thing, which rises question; how great must've the Creator be, and how majestic wold be to meet Him.

Having been alive for 50 years and having paid attention to older people when I was little, I can entirely believe the World Health Organization when they said, before COVID-19, "We're the sickest we've ever been." Propagandists answer this by questioning the meaning of the word "disease"; it's disgusting to hear! And I have reason to believe that disease is connected with overpopulation.
Ugh! That's enough of problems. I could write a lot more, listing problems and evidence, but the birds are singing on this bright morning and I've got to get myself a tasty breakfast. ;) I'm hoping for God's Kingdom to end the mismanagement. There is evidence it's real.
I am not convinced; my girlfriend is pretty adamant I'm the most dense object in our solar system.
Get off your big fat mass and do something with your life
😂
Man, watching your videos always gives me the urge to play some KSP
Great video, as always, Alex
11:54. I live there
This is one of the best video's I've ever seen about earth, and in 20 minutes. That's quite an accomplishment. Thank you very much!
The green color is due to molecular oxygen emitting between 500-550 nm. The atomic oxygen has two bright lines at 777 nm and 844 nm. So, they contribute to red glow. Nitrogen molecule dominates the magenta glow (300-400 nm)
Beautifully told ❤
I really Nerded out to this. This was/is my favourite video of yours. Also favourite subject :D
Too early for the video today!!
Lol
That section at 3:22 was done really well
Thank you so much for this video!
Can we add having a semi molten core, creating a magnetic field, and a large enough moon to cause tides, and an ozone layer to the list of criteria required of a planet to be able to sustain life?
An amazing video, reminding us of the beauty of OUR Home.
I hope you hear the genuine appreciaton and respect from your viewers, disregarding the trolls. Unfortunately, they are a sign that your work has achieved a certain level of recognition and status, fwiw.
Thank you 💜🌍🌎🌏✊🍀
I think JRR Tolkin solved that monthly calendar problem with the Hobbits calendar way back in the 1930's
I really like your voice, explanation of the stuff of space contents really match domain
Outstanding video!
5:00
this is so crazy but im about 99.99% sure that I worked at this apartment complex. Everything about it looks exactly the same, seeing this just about threw me out of my chair once I saw it. Im almost certain. I worked there as an apartment maintenance technician back then.
Your third-person description of the Earth, as a celestial body, is quite delightful. I'm known as a bit of space nerd amongst my colleagues and they are often surprised that Earth is my favourite planet and by my reasoning,...it's where I'm from! =) Also I reckon it's the best looking planet in our Solar System
3:58 A year is actually 365.2425 days long. Every four hundred years, an additional leap day is added. For instance, 1600 and 2000, was a leap year, while 1900 or 1800 or 1700 was not. This is also not the perfect value either, it is just that the Gregorian calendar which most of us use, pretends that the year is a bit simpler.
Can we get a playlist for all the new “our solar systems planets” series now that the remasters are complete?
never heard of this planet before, maybe we'll visit it someday who knows
Great job Alex . You obviously put a great deal of work into this video. Yes Earth is a unique planet. It could of never happened by accident.
These scientists and ancient astronomers from a couple thousand years ago were just amazing. Goes to show you, for as long as humans have been around, there has always been bright, innovative people.
Best video ever Alex. Just beautiful, thank you.
9:22 🎶 The days are longer. The nights are shorter. The sun is shining. It’s noticeably warmer. Summer! Every single moment is worth its weight in gold. Summer! It’s like the world’s best story and it’s waiting to be told! 🎶
Wow, these images were so beautiful again.
Love watching your videos when I’m going to sleep
Earth is such a fascinating place to live and learn about.
By the law of big numbers - yes, there is better Earth somewhere. But the chances of finding it, even if we had FTL, is probably near zero ;)
I'm mostly impressed with the substantiations in this video of my own late realizations that the entire cosmos seems to adhere to some divine plan of perfection and direction towards evolution based on a predetermined paradym of guidance from both the ultimate combined creative source and the variety of imaginative consciousness projected by sentient beings who just so hold the abilities of the imagination concepts
Thank u soooo much for this doc
All these years, never thought earth was this complicated.🌎
What a wonderful video, thank you!
COME ON LET HIM GET TO 2 MIL SUBS GO GO GO
A wonderfull video! Thank you!
Wonderful episode. I actually understood 99% of it. 😊
Earth sounds interesting. Maybe someday I will go visit it.
"Keeping time can be more complicated than you thought" this is exactly correct. I didnt realize how little I knew about time until I began studying for a world I'm creating.
The thing I thought would take a couple hours at most to study sucked me into a 2 month rabbit hole...and I may be more lost now than I was in the beginning, lmffao.
You got that thumbnail coment backwards. Earth spinning slows down. It ain't speeding up!
03:56. This is incorrect. The solar (tropical) year is 365 days 5 hours 48 minutes and 46 seconds, or 365.2422 days. The Julian calendar (after Julius Caesar) had 365.25 days and a leap year every four years, which by the 16th century resulted in a noticeable discrepancy between the calendar and the actual solstices and equinoxes, which was solved by Pope Gregory XIII in 1582. We don't have a leap year every 4 years anymore, but a Gregorian calendar.
Could you please do a video on what happens, and the timeframe involved, when the Moon finally pulls away from the Earth? I know it would be hypothetical because no one really knows what will happen, but that would be a very interesting video indeed! Thanks, Alex!
Great video with beautiful and stunning visuals of how truly amazing the Earth is. 😎
@astrumspace Thank you so much! This is top tier content. ❤
Our home!❤
I shed a tear there
This is the best one.
Our calendar is Lunisolar because our ancestors found out logically that not only Sun but Moon also plays significant role in our lives.
Also most unappreciated humanity's single most important resource. The irony that hits me when realizing we're ruining it on purpose, in a race of who's gonna get biggest pile of pieces of paper that has no other value to the whole system, except the one we decided it has. (Even tho most of it is now-days in digital form).
But the hope is in belief; that it wasn't a chance but intentional design of the whole thing, which rises question; how great must've the Creator be, and how majestic wold be to meet Him.
This was one of your best!
Awesome video once again!
