You are checking out FreeSchool! It's the brightest and most noticeable object in the night sky, but if you spend a lot of time watching it, you'll find that the moon is never exactly the same from one night to the next. The moon has what we call 'phases' which means that it seems to change shape a little every night. To understand why this is happening, we need to talk a little about how the earth and moon move together in space.
The moon orbits the earth, much like the earth orbits the sun. However, while the earth takes about 365 days to orbit the sun once - a year - the moon completes its orbit around the earth in just 29 and a half days - or about a month the moon takes one orbit - and the words 'moon' and 'Month' come from the same root. Although it appears so bright in the sky, the moon has no light of its own.
It only seems to shine brightly in the sky because the sun's light hits it and bounces off. Just like the earth, the moon has a day side and a night side, half of which is in sunlight and the other half in darkness. As the moon traverses its orbit around the earth, this dividing line between day and night, called the terminator, is visible from different angles, giving the impression that different amounts of the moon are illuminated on different days.
The cycle of the phases of the moon begins with the 'new moon'. At a new moon, the moon appears completely dark because the unlit side faces the earth. New moon is the only time in the lunar cycle that a solar eclipse can happen because the moon is only then between the sun and earth, and after a few days, when the moon has moved a little in its orbit, we can begin some of the Day sides of the moon can be seen from Earth.
What we see is just a thin streak of light called a crescent moon. We call it a 'growing crescent' because 'growing' means 'growing'. The crescent moon gets a little thicker every night until it reaches the next phase: the first quarter.
The first quarter moon is sometimes called the crescent because it looks to us like half the moon is lit, but it is called the 'first quarter' because the moon has a quarter of the way through its cycle. As the days progress, the moon continues to grow and soon enters its next phase, the waxing gibbus. Gibbus means 'hunched over' or 'puffy' and we call it wax again because it gets thicker every night until it reaches the next stage, the full moon.
A full moon is the largest, brightest, and easiest to see moon phase. The moon rises at sunset and is awake all night. So when you are outside and the sky is clear it is hard to miss it.
The moon is halfway around the earth and is now on the opposite side of the earth from the sun. With a full moon, there can only be a lunar eclipse, because only then could the earth's shadow fall on the moon. As the moon continues on its way, it seems to shrink again as we see more and more of its dark side.
A few days after the full moon, the moon will be a gibbus again, but this time it is a waning gibbous. 'Waning' means that the moon is shrinking or getting smaller, and so the moon will be decreasing for the remainder of its orbit. The next phase is another crescent, but this time it is called the 'third quarter' or sometimes the 'last' or 'last' quarter because the moon is three-quarters of its orbit.
Soon the crescent moon will shrink to a waning sickle that will continue to shrink night after night until it disappears completely in the next new moon. Big and bright and beautiful, different night every day but repeating the same cycle over and over again, the moon is one of the best objects in the sky to observe, especially for someone who is just getting started. The next time you look up and see the moon in the sky, take a moment and see if you can tell which phase of the moon you are seeing and try to figure out which is next.
The rest of the month we see parts of the daytime side of the Moon, or phases. These eight phases are, in order, new Moon, waxing crescent, first quarter, waxing gibbous, full Moon, waning gibbous, third quarter and waning crescent.

Hey Vsauce. Michael here. And I'm Regent's Park in London and Tom from '/ Tom'.
This camera belongs to Tom and Hazelis, who are currently operating it. Yeah, that's your thumbs up, which sure just looks blurry, but the point is, we're going to be giving information today. Right now, Tom, I'm in London.
What's in England. And it's in the UK too. What is in Europe.
Okay, and we have another term - Great Britain. Well, let's unwrap all of these terms and learn about geography today. Maybe I failed in geography.
Can i find someone else If we talk about geography now, we should go back to a time when there was no geography. That's true. Long before YouTube existed, our solar system was nothing more than a nebula of dust and gases known as the Sun Nebula.
But then something majestic happened about 4.6 billion years ago. We don't know exactly what caused it, but some scientists believe that the shock wave from a nearby supernova hit our nebula, causing it to spin and contract.
Now that things were gathering up, their overall pull got stronger and they pulled more stuff in. And boom, we have a sun Half a billion years later, the scrap disc orbiting the sun begins to unite in its own way into what we now call planets. I actually visited one of these planets and it's called Earth.
But before we overtake ourselves, what the hell is the moon doing there? I mean here is the problem. If you look at all the terrestrial planets, all the planets near us, near the sun, they all have a very similar structure and they have the same large metal core and they all have very similar densities. But the moon is very not dense.
And it doesn't have a similar structure, it doesn't have a huge, dense metal core. When we visited them and brought dust and rocks with us to analyze what the moon is made of, we found that the moon is made up of the same stuff you find in the earth's crust and mantle, but not earth score. This discovery led to a pretty great idea that the moon is actually made up of what used to be on earth.
About 4.52 billion years ago there was another planet called Theia. It was slightly smaller than Mars, but had an unfortunate orbit.
It was fine for millions of years, but eventually it happened that it collided with the earth. Now it is believed that the collision happened fairly slowly, and the centers, the cores of Theia and the Earth, merged into one. And material from the earth's mantle and crust was not only scattered, but ejected with force, literally hurled into space.
It circled the earth and scientists believe it only took about a week for all of the earth material in space to merge into what we now call the moon. Oh, and by the way, when the moon formed like this, it was such a strong collision that the actual axis around which the earth rotated was tilted 23.5 degrees, which is why we still have seasons of the continents as we do know them, began to develop.
You know, those parts of the earth's crust that have cooled down and floating around inside the earth's molten liquid. Now they are moving and have been in constant motion since they began, but they move very, very slowly. Every 300 to 500 million years the continents converge into a single large supercontinent.
All the land all over the world together and the rest of it covered with ocean. The youngest supercontinent is pretty famous, it's called Pangea. However, scientists believe that before Pangea there could have been four, five, six, or even more supercontinents.
What is really overwhelming is the fact that at some point there will be another Pangea, another supercontinent. And according to calculations, this is what the earth will look like at that time. But as I said, these land masses move very slowly and so it is worth learning their names as they are now.
That brings us back to the question of England, Great Britain, Great Britain, the British Isles and the meaning of all these terms. Let's start by zooming out. The British Isles and Ireland are a collection of 6,000 islands off the coast of Europe.
The term Great Britain refers to the largest of these islands. Now the UK includes three separate countries: England, Wales and Scotland. If we add Northern Ireland into the mix, let's now look at what is known as the UK or Great Britain.
The Republic of Ireland is a separate country that does not belong to the United Kingdom. And by the way, in England is London and there was Summer in the City. Which brings us back to Regent's Park.
And anyway, thanks for watching. Can you stop for a moment? To find out more about the UK, Ireland, overseas territories and even Canada, be sure to watch the explanatory article from CGPGrey haven't seen it yet. This guy is amazing.

So, remember when you see dazzling photos that feature a giant Moon above the landscape: those images are created by zooming in on distant objects near the ground. In other words, the Moon looks bigger in those photos because it's a zoomed-in view.24 2021 .
Why is the moon so big? Actually it's all in your head. What?!?!?! Hey Crazies. Have you ever looked at the moon when it's really low in the sky? It's that reddish-orange color and looks so much bigger.
The color is a real effect caused by the earth's atmosphere. The light needs to penetrate more air near the horizon and the air scatters away the blue half of the spectrum.
The same thing happens with the sun at sunrise and sunset. But the size of the moon is a complete illusion. No, really, it's all in your head.
It's called the 'moon illusion' and has been fascinating people for a very long time. To the timeline ! The earliest record we have The illusion comes from a cuneiform tablet dated to the time of King Assur-bani-pal in ancient Mesopotamia. This is today's Iraq, Syria and Turkey; but a long time ago! we also have a record from ancient China from the time of Confucius, however, people at that time were convinced that it was a real effect, they thought the moon had to be closer physically or the optics of the Atmosphere must enlarge enlarge picture.
Even Aristotle in ancient Greece believed that it was visual and we all know how his ideas turned out. It was not until about AD 1021 that someone finally questioned the concept of experimentation over 600 years before Galileo made him one of the first real scientists. He suggested that optics weren't quite enough to explain the moon illusion.
Why can't it be real? Because the moon's distance from us doesn't change - We saw in a previous article that the moon is so far from Earth, and because it's so far away, any changes in its distance tend to go unnoticed. Yes, the moon's orbit is elliptical, but drawing it this way is misleading. It looks more like this; it's almost circular.
That is, over the course of a month, the moon's distance changes only so much. It's not that much. So always the news or your friends are like: Oh my god! It's a super moon! It's actually not a big deal.
There is nothing great about it! To make matters worse, the moon looks bigger on the horizon where it is actually further away. This is the line you look into when the moon is high in the sky, but this is the line you look along when the moon approaches the horizon. This is an entire radius of the earth! That alone easily lifts everything optical Done in the atmosphere.
So what's really going on? There are actually several different explanations. Psychologists treat them like competing explanations, but for reasons I'll explain later, I think they're all at the same time. Let's do this! First my personal favorite: the Ebbinghaus illusion.
Your brain actually resizes things to add extra contrast. Look at the orange circles in this picture, the one surrounded by little blue circles looks bigger, but if you remove the blue circles you can see them the same size. Even now that you know they are the same ze, you still see them differently.
When I animate one you see the orange circle change size, when in fact it doesn't change. The idea is that something similar happens to the moon as it approaches the horizon, the moon rises, you have a ton of buildings and trees to compare it to. So your brain says, 'Wow, this is really big'.
But when it gets higher, it is only surrounded by the vast emptiness of the night sky, so it looks smaller. If you remove everything else from view, for example by looking through a roll of paper towel or just turning everything upside down, then the moon illusion is diminished for some people and eliminated for others, everyone, we need more explanation. The second possible explanation is the Ponzo illusion.
This is an example of what we call 'constancy of size'. Basically, our brains know that many things don't change size by accident. So when we see a person getting smaller, our brain simply interprets it as s, even though the person is further away.
The downside is that if something looks like it's going further but doesn't change its size, then it has to grow. So the idea here is as long as we have the same when the moon approaches the horizon it has to be further away but it is always the same size so your brain thinks it is bigger and it changes your perception accordingly. The problem is, very few people think that the horizon moon is looking further away.
Most people say he looks closer. Finally, we have the Sky Dome model. In contrast to the Ponzo illusion, which assumes a flat sky, the sky dome model assumes a curved sky over a flat floor.
It suggests that our brains may be mapping all of the really distant, conspiratorial stars and the moon onto an imaginary dome over our heads. The upside here is that it says we are connecting the sky to the ground on the horizon and, so underestimate the distance to celestial objects, we saw in the other article that at best we only see about 3 miles in each direction can. This makes the ground horizon in this picture about 5 miles away, so our brains assume that the distant clouds in the sky are also 5 miles away when those clouds are actually about 10 miles away.
A big underestimation. The thing is, none of these are dramatic enough to explain the lunar illusion. But if we look at all three at the same time, we could have something.
The moon illusion is subtle for some and dramatic for others. A small fraction of people don't even see it. Maybe that's because not everyone is affected in the same way.
Someone who is deeply affected by all of these like, say my mother will be overwhelmed by the size of the moon every time, so how does the moon illusion affect you?

In the last article we learned what is out of the universe. Comment response time! WillCant QuickScope asked what aspects of the universe are finite. As I've said in the last couple of articles, I would hope they all including the However, space cosmologists believe that space is infinite, but all they REALLY know is that the entire universe is at least 20 times larger than our observable universe.
Regardless, let's just say the space is infinite. Time does not seem to be a beginning of the universe. At least the universe as we know it and time as we know it.
It started about 380,000 years ago, 13.8 billion years ago, before this light was emitted. Speaking of which, several people asked why this was oval rather than a circle.
It is a map projection of the distant universe. The entire interior of the cosmic horizon sphere, flattened into a plane. It is oval for the same reason this map of the earth is oval.
Bobby Harper asked what extraterrestrials would see if they lived on the edge of the universe? No edge! The universe is either infinite or it curves back on itself. Those are your only options. The universe has no edges.
But if you do If you mean the edge of our observable universe, you would only see your own observable universe around you. Technically, everyone has their own observable universe around them. We're just a little too close to notice a difference.
Tooth and Sticks wonders what is the difference between 'nothing' and 'empty space' Space is just space and time, completely devoid of matter. Nothing is a complete lack of space or time. Literally nothing! Gauge Wiley pointed out that Numberphile made a article about how far it would take to travel to find copies of things Warning: It's a long way.
Jonathan Spking wants more Camera Shy Clone. He's adorable, isn't he? will see what I can do. And as the last deal, YouTube puts the normal annotations on May 2nd of a year, which means we're stuck with that 20 second mobi on le endscreen, so we're now forced to put the comment responses on our own The last article was a test run and the response seemed pretty positive.
For this article we're back to the old endscreen one last time because I felt like you deserved a little warning. Ahhhh! Change !!! Look, i don't like change either, but maybe i can reply to more comments? or at least more detailed replies to the same number of comments. Anyway, wacko, thanks for watching.
Until next time! What a beautiful moon tonight This is not a moon! This is a space station!
The five lunar phases that have been considered in the analyses (see the text for more details): new moon, waxing/waning crescent, first/third quarter, waxing/waning gibbous and full moon.
For the most part, a full moon doesn't cause people to become more aggressive, violent, anxious, or depressed. There does seem to be a link between the phases of the moon and changes in symptoms of bipolar disorder. .
The January full moon is often called the Wolf Moon, according to the Old Farmer's Almanac, which may date back to Native American tribes and early Colonial times when wolves would howl outside villages. .
When you see a moon low in the sky it is because you are seeing it through a greater thickness of Earth's atmosphere. This is known as the 'moon illusion', according to EarthSky.org. When the moon is near the horizon you are looking at in comparison to familiar reference points such as trees, buildings, mountains, etc.
The Worm Moon is considered the last full moon of winter and is named after earthworm casts that appear as the ground thaws, NASA reported. It also signifies the time of year when earthworms and grubs come out of dormancy, according to the Farmer's Almanac. .
Moons in dreams have different meanings - they can symbolize important females in your life, and several moons can relate to timing in moon calendar with 28 days (a female cycle), so 5 moons will mean 28 days times 5.
The shortest lunations result when the new Moon coincides with perigee and Earth is at aphelion. One of the shortest lunations was 29 days, 6 hours, and 35 minutes, whereas one of the longest was 29 days, 19 hours, 55 minutes.
