This project shows how to calculate the rotational period of the Sun, as well as its lifecycle through history.
Welcome to the next video about our beloved star, the Sun.
00:00:01
We are a team of scientists and engineers who study the stars and outer space.
00:00:05
Have you ever wondered how the stars are born, or how then our Sun will die?
00:00:11
Or even, does the Sun rotate?
00:00:18
If that is the case, then keep watching to see the answers of my teammates.
00:00:20
Hi! We are Erika, Kike and me, Akram, and we are going to show you how the Sun evolved during its life.
00:00:26
At the very beginning, about 5 billion years ago, our star was just a large cloud of gas and dirt with many different colors,
00:00:33
called stellar nebula, just like confetti.
00:00:40
Then it began to shrink and its density increased, forming a baby Sun.
00:00:43
Observing other stars with similar sizes, astronomers have been able to say how it will evolve during the following billions of years.
00:00:48
of years that's right and don't worry the Sun won't die in the near future and
00:00:55
we won't be able to see it as it will happen in another five billion years but
00:01:01
before its death it will grow and grow and grow to become a red giant and it
00:01:07
will engulf Mercury and Venus and perhaps Earth then it will start to
00:01:14
shrink again and when it fades away it will become a small white dwarf. There
00:01:20
won't be any explosions or supernovas? I'm sorry but that will never happen to
00:01:28
our Sun. It's way too small to become a black hole like many people may think.
00:01:34
Now I guess you want to see some experiments right? Well Kike will show
00:01:39
you how to represent the life of the Sun in just two easy experiments. The first
00:01:45
In the next experiments we will show you how the atoms are expelled from the star throughout its life cycle.
00:01:48
To do so, we will hold a tennis ball on a basketball and let them fall.
00:01:55
The tennis ball will be launched into the air really fast.
00:02:01
To try it, our second experiment consists of showing how the sun will die.
00:02:05
We will represent the sun with a balloon full of color powder.
00:02:11
We need to inflate the balloon as much as we can and then pop it.
00:02:14
This is the form of a cloud of colors called the planetary nebula.
00:02:20
And that is the way that a normal star will die, but our sun, no.
00:02:27
That sounds really nice.
00:02:33
You've explained everything about the sun's life cycle, but we don't know yet if it rotates.
00:02:35
Can you tell us, Diego?
00:02:40
Yes, the Sun rotates, indeed, but not like our parent does. The Sun is made of plasma and there is no soil to hold it together.
00:02:42
Therefore, the Earth's middle equator rotates faster than the one at the poles.
00:02:54
Interesting, but how can we know that?
00:02:59
By comparing the latitudes and longitudes of a sunspot during a period of time.
00:03:03
This way, we know the speed at which it is moving, and we can calculate the Euler's rotational period and the differential rotation.
00:03:08
And why did you all decide to talk about these two topics?
00:03:17
We thought it was important that everyone knew that the Sun was an average star, which won't die as a supernova,
00:03:21
or that it doesn't rotate at the same speed as Euler's old RS.
00:03:27
The Sun is, after all, our nearest star, and it would so learn as much as possible we could about it.
00:03:33
And you? Do you think it's important to know a lot of information about the universe outside our world?
00:03:42
We hope you have enjoyed the video and that it has inspired you to share some more about the Sun. Goodbye!
