We are not confined only to Earth. We, humans, are trying from decades to be familiar and to find some interesting facts about the universe. Scientist researchers are not only limited to Earth now but they are more interested in outer space now where there still occur many phenomena which are still unexplainable to humans.
Here are 10 facts about the universe which scientists have discovered during their research:
1. Olympus Mons.
Mount Everest is the tallest mountain on Earth but have you ever cared about knowing which is the tallest structure in this Solar system.
It is Olympus Mons. It is the tallest structure in our Solar system situated on planet Mars. It’s 22 km tall. It is almost 3 times of the size of Mount Everest.
It is the largest volcano discovered in our solar system. Just compare the size of it.
2. About 1% of the static on your TV is caused by cosmic microwave Background(CMB) radiation left over from the big bang about 13.7 billion years ago. Basically, this is what we saw on old television.
3. There Are at Least 10 Billion Trillion Stars in the Universe.
Now that is a huge number. Also, this number is only expected by Scientists. There is no real proof of this number. But this is just on the lower bound. This number can go much much large. Just imagine the number of zeros. that can go to like 10,000,000,000,000,000,000,000.
4. One Million Earths Could Fit Inside The Sun.
Sun is considered as a dwarf star in Universe but still, it has got its importance and for Earth it the most important star. Now we all know that our Earth is huge. Just imagine the size of the sun now. Nearly 1 million Earth can be submerged into Sun.
5. The Sun is about 93 million miles (150 million km) away from Earth.
This would take you around 150,000 years if you start today to reach Sun at speed of 1000 km/h.
6. Our Galaxy is on a Collision Course with the Andromeda Galaxy.
Andromeda Galaxy is the nearest galaxy to our milky way galaxy and they both are on the collision course. Yes, you heard that right they both are colliding. Though there will be no impending impact of this for next 3 billion years.
7. Earth’s rotation is slowing at a rate of approximately 17 milliseconds a century.
During the Dinosaur time, the day on this earth was of around 22 hours only. Though it took around 250 million years for the earth to reach 24 hours a day. Lazy Earth.
8. The oldest known object in the universe is a galaxy called z8_GND_5296. It’s 13.1 billion years old – only about 700 million years younger than the universe.
9. When you look into the sky in the night, you are actually looking back in time.
The stars we see are at a far distance from earth. The time it takes for the light to reach our eyes from these stars are millions of years. So when we see these stars we are actually seeing them in the past.(the light which has travelled from the past to reach our eyes)
10. There’s a giant cloud of alcohol in Sagittarius B.
Sagittarius B is a vast molecular cloud of gas and dust floating near the centre of the Milky Way, 26,000 light-years from Earth, and it contains 10-billion-billion-billion litres of alcohol.
11. Venus takes more time for the rotation than revolution around the sun.
This makes year on venus shorter than its Day.Venus is the slowest rotating planet in our Solar System, so slow that it takes longer to fully rotate than it does to complete its orbit.
12. Voyager 1 spacecraft is the farthest human-made object from Earth.
Voyager 1 spacecraft was launched in 1977 and in 2013 it was the first object to leave our solar system. It is currently 1.15581251×1010 miles away from earth.
This is the photo of Earth taken by Voyager 1 from some other galaxy.
