10 Most Amazing Facts About The Universe
The Universe is, as we say, a collection of planets, stars, galaxies, and all other forms of matter and energy. While it is possible to measure the observable universe, the total size of the entire Universe is still unknown. In this article, we will explore the mysteries and wonders with 10 amazing facts about the Universe that will blow your mind.
Amazing Facts About the Universe
1. Venus: A Year Shorter Than a Day
Venus is the slowest-rotating planet in our Solar System. It is so slow, that it takes 243 days to fully rotate on its own axis and 224 days to complete its orbit, which means that on Venus, days that last longer than years.
2. Mercury: A Day Longer Than a Year
Mercury revolves around the sun faster than other planets, which makes its year equivalent to 88 Earth days. While a day on Mercury lasts 176 Earth days making it longer than the year.
3. The weight of a spoonful of a neutron star is a billion tons
A neutron star is the collapsed core of a massive supergiant star and its core is the densest matter in the universe outside of a black hole
Amazing Facts About the Universe: It is calculated that if you could collect a spoonful of matter from the centre of a neutron star, its weight would be about a billion tons.
4. Looking into the night sky enables you to look back in time
The stars we see in the night sky are very far away from us and the starlight we see has taken a long time to travel across space and has then reached our eyes.
This means that whenever we look outside at night and look at the stars, we are actually seeing how they looked in the past, thousands of years from now.
5. The Hubble telescope can help us look back billions of years into the past
In this infinite universe, we are able to see very distant objects because of the Hubble Telescope. It is created using images from the telescope from 2003 and 2004 and the incredible picture displayed is a tiny patch of the sky in detail.
These details contain 10,000 objects and act as a portal back in time. In one picture 13 billion years are transported into the past to us.
6. Watching the Big Bang on TV
Cosmic background radiation is the afterglow and heat of the Big Bang which started our universe 13.7 billion years ago.
This cosmic echo exists throughout the universe, of which we can also catch a glimpse by using an old-fashioned television set.
When television is not tuned to a station, we can see some black-and-white fuzz and clacking noise and around 1% of this interference is made up of cosmic background radiation.
7. A massive water body is just floating around in space

Amazing Facts About the Universe: There exists an enormous reservoir of water floating in space. A gigantic water reservoir floating in space which has 140 trillion times all the water in the world’s ocean.
8. No Tears: You cannot cry in space
You cannot cry in space because, without gravity, tears don’t flow downwards out of the eye and do not wash away irritants from our eyes.
Instead, they accumulate into a little ball of liquid that keeps hanging in the eye.
9. Size of Universe?
The expansion of the universe is infinite or we can say it is much bigger than what we can see.
The observable universe is a ball-shaped region of the universe that includes all matter that can currently be observed from Earth or its space-based telescopes and exploratory probes.
The distance from Earth to the edge of the observable universe in any direction is approximately 46.5 billion light years. Thus, the observable universe is a sphere with a diameter of approximately 93 billion light years.
10. How old is our universe?
We don’t fully understand the universe, but we’re pretty sure it’s about 13.8 billion years old. Some evidence suggests that it may or may not be exactly 26.7 billion years old.
According to the Big Bang theory, about 13.8 billion years ago, everything in the universe collapsed into a small, incredibly dense and hot point. Then, there was a massive explosion that caused the universe to expand rapidly, even faster than the speed of light.
