Nebula. The place where the star is born

We have been trying to know the mystery of creation since human creation. But this Universe of ours is a treasure trove of mysteries. Because of this, since ancient times, people have begun to speculate about the mass of the universe that travels far beyond our earth. From ancient times, when people saw the open sky at night, they wondered what was in store for the stars in the distant sky. In the past, we were only able to guess a few stars because of the lack of modern technology. With all the advanced technology in boot today, we can get a clearer idea of ​​the world of those stars.

How the stars are created and how far away they are from us. Let us know from today’s discussion about the place in the universe where the stars are born. With this we will know some mysterious and unknown information of that place. In astronomy, the nebula is called the place where the stars are born. The nebula is a Latin word. Which means cloud. Far beyond the limits of our solar system, the center of the distant stars, the part where darkness always lies. Or it could be called the space between the galaxies, which we call interstellar space.

One hundred years ago we used to think of interstellar space as a vacuum. But today we know that the interstellar space is filled with dust dust particle and radiation. This interstellar medium is filled with about 99% gas. 75% of this gas is hydrogen and the remaining 25% ​​is helium. This interstellar gas, which is widely dispersed when it comes together due to mutual gravitational interaction, forms a nebula. It can be said that the nebula is a huge gas cloud. The nebula is a cloud of oceans, formed by interstellar dust, hydrogen, helium and dust. In the beginning, astronomical objects and galaxies, which were widely dispersed in astronomy, were considered nebulae. Prior to the twentieth century, when the galaxy had no definitive definition, scientists considered our neighboring galaxy Andromeda to be a nebula.

At that time the Andromeda Galaxy was called the Andromeda Nebula. On the other hand those galaxies that were spiral were called spiral nebulas. Since a nebula is large enough to form a gas cloud, it can be easily seen from our earth. This nebula can range from 100 to 1000 light years. Nebula is also called Star’s Nursery. All kinds of stars, big and small, are born here.

The nebulae are of various sizes and are oddly shaped to see. For example, some nebulas look like horses, crabs, butterflies, and cat eyes. We know that the stars are born in nebula gas. Let’s see how it goes. According to the scientists, all these nebulas are found in large quantities of gas and dust, due to the gravitational pull of these gases and dust began to accumulate in one place. As a result, these clouds begin to thicken. The more dense the cloud, the hotter it gets. Eventually it gets so hot that it mixes with hydrogen to create new stars. When the star was born in Nebula, the new star’s ultraviolet ray spread throughout Nebula. Causing the whole nebula to shine in the light. This type of nebula is called Emission nebulae .This is one of the few nebulae. Emission nebulae are usually red or pink in color. The orion constellations that we see from Earth are also an Emission nebulae.

Another nebula is also seen. The name is Reflection Nebula. This nebula does not reflect its own expression. And it reflects the light that this nebula receives from those closest to them. Reflection The nebula is blue. If you look at a reflection nebula, you would think that there are immense nebula reserves around it. And next to the orion constellations there are reflection nebula reserves. This nebula looks a bit like ghostly hair.

Friends are more likely to see a nebula of sorts. Whose name is planetary nebula. Don’t go in for a name. Because with planetary nebula, Planet has no relation. This type of nebula is born when a sun-shaped star releases hydrogen fuel from its core. And this star’s outdoor cell begins to hydrogen fuse. As a result, the star began to expand. Later it turns into a Red Giant Star. Gradually, the core of the star began to heat up. Because of this, the layer then starts to fuse helium atoms. Because it fuses all the hydrogen atoms inside its helium atom. And finally when it fuses Helium Autom too, the Star’s image becomes unstable. Later Stars spread his core into space. This dispersed layer is called the planetary nebula. It later turns into a white dwarf star. But still, the radiation of this station continued to spread. And this radiation produces the color of the light in combination with the atom of the gas. And that’s why it’s called the Planetary Nebula.

Another nebula like this is in our Universe. That is called the crab nebula. This crab nebula is caused by a supernova explosion from a huge star. The coldest place in our universe that would be called Nebula would be this one. We know the name Boomerang Nebula. It’s also called the Bow Tie Nebula. The discovery of two such nebulae was first made in the 1980th. But the full view of the nebula was not taken then. Only the lower part of the nebula was seen.

The nebula was then completely visualized by the Hubble Telescope in the 1998th. This nebula is considered the coldest. The nebula has a temperature of minus 172 degrees Celsius. Which is only one degree above the absolute zero temperature. The absolute zero temperature is minus 172.15 degrees Celsius. Tell those who do not know the absolute zero temperature. Absolute zero temperature is the temperature from which it is no longer possible to major its own temperature.

Next, the nebula I will know about is the eagle nebula. This nebula looks a lot like an eagle’s. Scientists think this nebula is giving birth to all new levels. This nebula is also called the queen nebula. About another mysterious nebula for later. And the name of this nebula is the Dark Nebula. The reason this nebula is named Dark is because its cloud is so dense. The light of the stars in this nebula cannot penetrate the cloud of nebula. This cloud completely blocks the light.

This nebula This nebula is only visible when a star’s light can come out of the cloud. This nebula can block the light because the dust particle size stored in the cloud is similar to the submicrometer. It contains layers of nitrogen and carbon dioxide. Capable of blocking any kind of light. This means that friends can say it in one sense. The Dark Nebula may disappear. Unless any light inside it can come out. The Coalsack Nebula is one such example

After about 5 billion years, our sun will create a nebula. The nearest nebula we see in the world is the orion nebula. That is 1344 light years away from us. The nebula is spread over an area of ​​about 25 light years. Scientists think some nebulas may have another nebula inside.

So friends today, from this discussion we learned about Nebula. Where stars are born. If you like today’s information, you will find many more such information on my blog site. That I share with you.
