Have you ever looked up at the night sky and wondered what space is? It's this vast, mysterious area that we're still trying to understand. In simple terms, space is everything beyond our planet Earth. It's where all the stars, planets, and galaxies are located.
Space is mostly empty, with just a few bits of matter scattered throughout. But even that matter can be incredibly important. For example, the Sun is a huge ball of matter that gives us light and heat, and the Moon affects our tides and has a big impact on our planet.
There's a lot we still don't know about space, but we do know that it's constantly expanding. This means that the distance between galaxies is getting bigger and bigger as time goes on.
One of the most fascinating things about space is the concept of gravity. Gravity is what holds everything together in space, from the planets in our solar system to the stars in a galaxy. It's what keeps us firmly planted on the ground and prevents us from floating off into space.
Another interesting concept in space is time. We know that time is different in space than it is on Earth, and this has been confirmed by various experiments and observations. Time can also be affected by gravity, which means that time moves slower near massive objects like black holes.
Despite all the mysteries and complexities of space, it's an incredibly important area of study. We rely on space exploration for a lot of things, from satellite communications to weather forecasting. And who knows what else we might discover as we continue to explore and learn more about this vast, intriguing area of our universe.
In short we can say that everything above 100kilometres is space. space is the part of the universe that is past the Kármán Line, which is the separation between Earth's atmosphere and everything else. Space is the place above our planet where there is no air to breathe. It is the expanse that exists beyond Earth and its atmosphere and between celestial bodies.
So the furthest out we can see is about 46.5 billion light years away, which is astonishing,there are at least 100 billion galaxies – each home to around 100 billion stars and several planets.
we know of the universe is only a tiny fraction of what is out there. We know only five per cent of the universe.The remaining 95 per cent is still undiscovered and a mystery.The probe launched on Sept. 5, 1977 — about two weeks after its twin Voyager 2 — and as of August 2022 is approximately 14.6 billion miles away from our planet, making it Earth's farthest spacecraft.
