Saturn’s rings are made up of billions of tiny particles of ice, ranging in size from grains of sand to massive boulders.
The Andromeda Galaxy, our closest neighboring galaxy, is heading towards the Milky Way at a speed of about 110 kilometers per second.
Space is not completely empty; it contains a very low density of particles called interstellar medium.
The Hubble Space Telescope has captured images of galaxies that are billions of light-years away, allowing us to glimpse into the distant past.
The space between galaxies is expanding, causing them to move away from each other, which is why the universe is expanding.
Astronauts on the International Space Station experience 16 sunrises and sunsets every day due to its fast orbit around the Earth.
Space is not completely dark; it contains faint light from distant stars and galaxies, even in the absence of nearby sources of light.
The Milky Way, our home galaxy, is estimated to contain between 100 and 400 billion stars.
The surface gravity on a white dwarf, a dense star at the end of its life, is about 350,000 times stronger than on Earth.
The largest volcano in the solar system is Olympus Mons on Mars, which is about two and a half times the height of Mount Everest.
The Voyager 1 spacecraft, launched in 1977, has exited the solar system and is currently traveling in interstellar space.
The space between the Earth and the Moon is so vast that you could fit all the other planets of the solar system in that distance.
The center of a black hole is called a singularity, where gravity becomes infinitely strong and our understanding of physics breaks down.
Neutron stars are incredibly dense, with just a teaspoon of neutron star material having a mass of about a billion tons.
The Sun’s gravity is so strong that it keeps all the planets, asteroids, and comets in our solar system in orbit around it.
The concept of a wormhole, a theoretical shortcut through space-time, was first proposed by physicist Albert Einstein’s equations.
The Great Attractor is a region of space, about 250 million light-years away, where galaxies are moving towards it at high speeds.
Astronauts experience a sense of weightlessness in space because they are constantly falling towards the Earth but also moving forward at high speeds.
Space debris, including old satellites and fragments from rocket launches, pose a significant threat to active spacecraft and can cause collisions.
In space, your tears would not fall down due to the absence of gravity, but they would form into spheres and float in front of your eyes.
The James Webb Space Telescope, set to launch in 2021, will be the largest and most powerful telescope ever built, allowing us to see even deeper into space.
The immense gravitational pull of a black hole is so strong that not even light can escape it, hence the term black hole.
The Apollo astronauts left retroreflectors on the Moon’s surface, which can still be used to bounce laser beams off them to measure the exact distance between the Earth and the Moon.
Space travel can cause temporary changes in vision for astronauts, as the fluids in their bodies shift due to the absence of gravity.
The International Space Station is a multinational collaborative venture involving the United States, Russia, Canada, Europe, and Japan.
A supernova, the explosive death of a massive star, can briefly outshine an entire galaxy and release more energy than our Sun will emit over its entire lifetime.
Space exploration has led to numerous technological advancements, including satellite communications, weather forecasting, and GPS navigation.
The oldest known object in the universe is a star called Methuselah, estimated to be about 14.5 billion years old.
The farthest human-made object from Earth is the Voyager 1 spacecraft, which is currently over 22 billion kilometers away, exploring interstellar space.
The Mars Rover missions have discovered evidence of ancient water on the surface of Mars, suggesting that the planet could have once supported microbial life.
