Some of the most stunning and colorful auroras occur on the gas giant planets like Jupiter and Saturn.
The biggest explosion ever observed in space was a gamma-ray burst, which released more energy in a few seconds than the Sun will emit in its entire lifetime.
The average temperature on the surface of the Moon can range from about 260 degrees Fahrenheit (-127 degrees Celsius) at night to 280 degrees Fahrenheit (138 degrees Celsius) during the day.

The Voyager 1 spacecraft, launched in 1977, is the farthest man-made object from Earth and is currently traveling in interstellar space.
The surface gravity of Mars is about 38% of Earth’s, meaning you would weigh less on Mars.
The Hubble Space Telescope can see objects in space that are billions of light-years away, allowing scientists to study the early universe.
Space is not completely black; it actually has a faint glow called the cosmic microwave background radiation.
The first woman to travel to space was Valentina Tereshkova, a Russian cosmonaut, in 1963.

One Mars year is about 687 Earth days.
The International Space Station travels at a speed of about 5 miles per second (28,000 kilometers per hour) in orbit around Earth.
Space is a vacuum, which means it doesn’t contain any air or matter.
The space between galaxies is not completely empty, but contains sparse gas and dust.
Mercury is the smallest planet in our solar system, even smaller than some moons.

Space travel can cause changes in astronauts’ vision due to the fluid shifts in their bodies in microgravity.
The closest galaxy to our Milky Way is the Andromeda Galaxy, located about 2.5 million light-years away.
The largest moon in our solar system is Ganymede, which is even bigger than the planet Mercury.
Uranus and Neptune are often called ice giants because a significant portion of their composition is made up of frozen gases.
