- It takes astronauts six hours to put on a space suit.
- In 840 AD, Emperor Louis of Bavaria died from fright during a solar eclipse thinking it was the world’s end.
- Pluto was reclassified as a “dwarf planet” in 2006, 76 years after it was discovered as the ninth planet.
- Earth is so small that it could fit inside the sun 1.3 million times.
- The moon’s gravity and the sun’s create Earth’s tide and move massive amounts of water daily.
- There are many facts about Black hole one of them is it formed when big stars explode. Their gravity is so strong that even light can’t escape.

9 Mind-Blowing Facts about the Universe
Do you want to know what every Galaxy have in its centre? Or what are neutrinos? To get answers to all these questions read all the facts listed below –
- Every Galaxy has a black hole in its center which weighs more than the sun.
- The leftover heat from the Big Bang, called the Cosmic Microwave Background, fills the whole Universe. What’s amazing is that this heat is almost the same temperature everywhere, even in parts of space that should never have been able to share heat or energy with each other.
- Only 5 % of the universe is made of ordinary matter like stars, planets and us! The rest is invisible: 27% is dark matter, which affects gravity, and 68% is dark energy, which makes the Universe expand faster.
- Every second, 100 billion ghostly particles called neutrinos pass through your thumbnail from the Sun.
- Even in the vacuum of space, there are still a few particles and tiny amounts of gas floating around.
- In the whole universe, Earth is the only place known to have life.
- Most gravity pulls things together, but dark energy has a kind of “repulsive gravity” that pushes galaxies apart and speeds up the Universe’s expansion.
- The universe was started with the Big Bang Theory.
- Many star systems have planets that orbit closer than Mercury or have “ hot Jupiters”, massive planets close to their stars.

The 5 most unique facts about the universe are:-
1. The Universe is constantly expanding, with galaxies moving away from each other.
2. About 27% of the Universe is made up of dark matter, which we can’t see but know exists due to its gravitational effects.
3. Black holes are regions in space where gravity is so strong that nothing, not even light, can escape
4. The leftover heat from the Big Bang, known as the Cosmic Microwave Background, is spread evenly throughout the Universe.
5. There are an estimated 2 trillion galaxies in the observable Universe.
Here are 10 facts about space:–
1. Space is vast and possibly infinite, with no known boundaries.
2. Light from the Sun takes about 8 minutes to reach Earth.
3. Time moves slower in stronger gravitational fields, a concept from Einstein’s theory of relativity.
4. Millions of asteroids and comets exist in our Solar System, many in the asteroid belt between Mars and Jupiter.
5. There are eight recognized planets in our Solar System, each with unique characteristics. 6. Neutron stars are incredibly dense remnants of supernova explosions, with a sugar-cube-sized amount weighing as much as a mountain.
7. Supermassive black holes exist at the centres of most galaxies, including our Milky Way, 8. Gravitational waves are ripples in spacetime caused by massive events, such as colliding black holes.
9. Thousands of exoplanets (planets outside our Solar System) have been discovered, some potentially capable of supporting life.
10. Pace is a near-perfect vacuum, meaning it has very little matter and almost no air.
