20 Amazing Facts about the Milky Way Galaxy Video
Milky Way Galaxy Fact 1
The Galaxy where we live is known as the Milky Way. The milky way is a spiral shaped Galaxy containing upto 400 billion stars that also includes our own star the Sun. So the Sun is present in the Milky way galaxy along with its member planets containing our home planet Earth.Milky Way Galaxy Fact 2
Our solar system is located in one of the spiral arms of the Milky Way. We are present at a huge distance of 26,000 light years from the centre of our Galaxy. Here let me tell you that one light year is equal to nearly 9.46 trillion kilometres.Milky Way Galaxy Fact 3
In March 2019, astronomers reported that the mass of the Milky Way galaxy is equivalent to 1.5 trillion solar masses, which was over twice as much as was calculated in previous studies. It suggests that nearly 90% of the mass of the Milky way Galaxy is the mysterious Dark Matter.Milky Way Galaxy Fact 4
Let's now talk about the size of our Galaxy, The diameter of Milky way is more than 150 thousand light years. It means, Our galaxy milky way is so big that even if we could travel with the speed of light, which is the maximum speed possible theoretically i.e. 300k km per sec., it would take 150k years to travel from one end of the milky way to the other.Milky Way Galaxy Fact 5
When we see the milky way at night with our naked eyes, we see only about 0.0000025% of the galaxy's hundreds of billions of stars.Milky Way Galaxy Fact 6
Our Milky Way galaxy contains a supermassive black hole at its centre having a huge mass equivalent to 4 million Suns. This giant black hole is known as Sagittarius A*.Here you should not think that sagittarius A* is the only black hole that our galaxy contains. This Is the biggest black hole present in the Milky way. Actually our galaxy may contain nearly 100 million black holes.
Milky Way Galaxy Fact 7
Our milky way is a barred spiral galaxy. Barred means, central part of the milky way is bar shaped rather than an ordinary spiral galaxy.Milky Way Galaxy Fact 8
The stars that are present in the arms of the spiral galaxy are bigger and brighter. Not only this, these stars also die out more quickly.Milky Way Galaxy Fact 9
The oldest star present in the Milky Way was formed shortly after the big bang. Astronomers have estimated that this star was formed at least 13.6 billion years ago. Having so old star means that the Milky Way came into existence just after the Big Bang. So our Galaxy is one of the oldest Galaxies present in the universe.Milky Way Galaxy Fact 10
The Milky Way has grown in size by merging with its neighboring galaxies with time. Currently it is sucking up material from the Magellanic clouds and snatching Stars from a very small Galaxy known as the Sagittarius dwarf spheroidal.Milky Way Galaxy Fact 11
You will find it unbelievably surprising, that the milky way is moving through space at a speed of nearly 552 kilometres per second. This speed is measured with respect to the cosmic microwave background radiation.Milky Way Galaxy Fact 12
According to astronomers, in the next 5 billion years, our Milky Way galaxy will collide with its neighbouring Andromeda Galaxy. The two Galaxies are moving towards each other at very high speed of 120 kilometres per second. This collision may last for about 5.5 billion years. When the collision Is over, the Milky Way and Andromeda galaxies will no longer be two spiral galaxies. They will form a single and bigger elliptical galaxy.Milky Way Galaxy Fact 13
Do You know that there are billions of galaxies smaller and larger than the milky way in the universe? The Milky Way galaxy is a huge group of stars, dust, gas and other material, which is held together in space because of their mutual gravitational force of attraction.Milky Way Galaxy Fact 14
Researches show that the Milky Way has a halo of dark matter. The halo makes up over 90% of its total mass. So even with the help of telescopes what we can see, is only 10% of the mass of the Milky Way.Milky Way Galaxy Fact 15
The stars present near the center of the Milky Way are the oldest and most massive stars while the spiral arms of the Galaxy mostly contain newborn stars.Milky Way Galaxy Fact 16
Even though there are 400 billion stars in The Milky Way galaxy, still the nearest star, the Proxima Centauri is present at a distance of more than 4 light years from us. Keep it in mind, that our Sun is actually the nearest star to the earth, the proxima Centauri is nearest after the Sun.Milky Way Galaxy Fact 17
All the galaxies are categorized into three main groups on the basis of their shapes. These types are- Spiral galaxies like our own Galaxy the Milky Way, Elliptical galaxies and Irregular galaxies.Milky Way Galaxy Fact 18
As we know that our home planet earth is revolving around the sun, but do you know that our whole solar system along with its all the member planets is also orbiting the centre of the Milky Way Galaxy!!! The solar system is revolving around the Centre of the milky way really fast, at a speed of about 220 kilometres per second. But even at this high speed it takes it about 230 million years to complete just one revolution around the center of the Milky Way. Therefore this period of 230 million years is called as one Galactic year.Milky Way Galaxy Fact 19
The Milky Way is not just travelling through the space at extremely high speed, it also has rotational motion. It's spinning at 270 kilometres per second and takes nearly 200 million years just to complete one rotation. With this fact only, you can imagine the size of the Milky Way.Milky Way Galaxy Fact 20
The milky way is popular by different names in different countries and civilizations, like in China, it is known as "The silver river". Romans called our galaxy "The Milky Road". The Greeks called it the "Milky Circle". It's interesting to note that, the word "Galaxy" itself means "Milk" in Greek.In Sanskrit the Milky way is called the "Akash Ganga" or Ganges of the heavens".
So these were some incredible Top 20 Facts about our beautiful, Old and Huge Galaxy, The Milky Way.
