Galaxies
1. How many galaxies are there in the universe ?
There are an estimated 2 trillion Galaxies.
2. What is the biggest Galaxy?
Alcyoneus is the biggest galaxy known to man.
3. Which is the nearest Galaxy to us?
Andromeda galaxy is the nearest one to Milky Way.
4. Will the Milky Way die?
From what we know about the behavior of galaxies, two galaxies can collide to form a new one. It is predicted that the Milky way and Andromeda will also collide. But don’t worry, the galactic collision is predicted to happen in 4.5 billion years.
5. How many planets are in our galaxy?
It is estimated that the milky way has between 800 million – 4.5 Billion planets.
6. Which is the biggest star?
UY Scuti is the biggest known star in our universe while the sun is the biggest star in our solar system.
How Many Galaxies are in the Universe?
Years ago when the great astronomer Galileo looked through his telescope into an ocean of stars, we were first introduced to our galaxy, The Milky Way. Since then the mere size of our universe has continued to baffle us.
Later in 1924, Edwin Hubble detected more fainter stars around nebulae. On further observation through this 100-inch telescope, he concluded that the seemingly fainter stars were too far away to be a part of our home galaxy. Further inspection into his curiosity led him to believe that we might not be the only galaxy in the universe.
Edwin Hubble created the Hubble telescope, which was a turning point in astronomy. The Hubble Telescope, located 525 km above the earth’s surface, helped us see into our galaxies’ past behaviour, formations, and destructions. It also helped assert that our universe is constantly expanding. Since this discovery, the universe’s expansion might also be slowing down significantly.
