The Great Red Spot on Jupiter is a massive storm that has been observed for over 300 years.
Space is constantly expanding, and the rate of expansion is accelerating.
The light from the Andromeda Galaxy takes about 2.5 million years to reach us, meaning we see it as it appeared 2.5 million years ago.
Saturn’s moon, Enceladus, has geysers that shoot out water vapor into space.
The tallest mountain in the solar system is on Mars and is named Olympus Mons. It is three times taller than Mount Everest.

The Pillars of Creation in the Eagle Nebula, captured by the Hubble Space Telescope, are giant columns of gas and dust where new stars are forming.
Jupiter has the shortest day among all the planets, completing one rotation in just under 10 hours.
The largest known asteroid is Ceres, which is considered a dwarf planet and makes up approximately 30% of the entire asteroid belt.
The moon has quakes, although they are called moonquakes. They are much weaker than earthquakes on Earth.

While space is often described as a vacuum, it is not completely empty and contains extremely low-density gas and particles called the interstellar medium.
The average distance between stars in the Milky Way is about 5 light-years.
The study of space and all celestial objects is called astronomy.
