Numerous people have always found the universe to be interesting. All of us find the components of our world to be fascinating, and we have long been curious about its many mysteries. We refer to the entirety of all physical objects that exist in space as the "universe." It is made up of many trillions of stars, galaxies, black holes, vast gas clouds, and many other exciting things.
1 - There is no centre and no edge to the universe.
1 - There is no centre and no edge to the universe.
It is impossible to reach the edge of the universe since it has no centre and is continually expanding (growing bigger) every second.
2 - The formation of black holes and their distance from Earth
3 - There are a lot of stars in the universe—possibly a trillion or more.
The precise number of stars in our universe is hard to determine. The total number of stars in the universe is greater than the total number of sand grains on all the beaches on Earth. That must be one billion trillion!
4 - How old is the universe, exactly?
4 - How old is the universe, exactly?
The universe is 13.5 billion years old, so even if the Earth is only 4.5 billion years old, it still only makes up a third of the cosmos's history.
5 - The cause of the earth's tides and waves.
On Earth, tides and waves are caused by the moon. It moves trillions of tons of water every day, together with the sun.

6 - In space, there is a lot of floating water.
Astronomers have discovered a massive water vapor cloud that is around 10 billion light years away and is 140 trillion times the mass of the oceans on Earth. The amount of water found there is the largest ever.
7 - The temperature of the hottest planet in our solar system is 450 °C.
8 - On Mercury, a day lasts longer than a year!
9 - Spacesuits cost close to $12 million and need to be worn for six hours by astronauts.
Astronauts travel into space while wearing spacesuits, which must be heated, cooled, pressurized, and supplied with fresh air. They need six hours to do this! Although the full suit costs $12 million, the backpack and control module account for 70% of that sum.
10 - Pluto was discovered in 1930, and 76 years later it was reclassified as a "dwarf planet."
7 - The temperature of the hottest planet in our solar system is 450 °C.
With an average surface temperature of about 450 °C, Venus is the hottest planet in the solar system. The fact is that Venus is not the planet that is nearest to the sun; that is Mercury. The hottest would seem to be Mercury, but as it lacks an atmosphere (which regulates temperature), there are large temperature changes.
8 - On Mercury, a day lasts longer than a year!
Since Mercury revolves around the sun more quickly than any other planet, its year is equal to 88 Earth days. While the time between sunrise and sunset on Mercury is 176 Earth days long!

After spending 76 years as our solar system's outermost planet since its discovery in 1930, Pluto was reclassified as a "dwarf planet" in 2006.
