Some interesting facts about space are - 

Black holes

A black hole is formed when a large star's core collapses, causing a supernova and blasting part of the star into space. 

Floating space water

In 2011, scientists discovered a massive reservoir of water floating in space, which is 140 trillion times the amount of water in all the oceans. 

Milky Way

The Milky Way is warped, dusty, gassy, and has over 200 billion stars. It also has an invisible halo and a black hole at its center. 

Solar system

The solar system is made up of stars, planets, and other objects that orbit the sun due to the balance of the planet's movement and the sun's gravity. 

Astronauts grow taller in space

Astronauts can grow up to 3% taller in space due to the lack of gravity, which allows their spines to stretch. 

Great Red Spot

Jupiter's Great Red Spot is a giant spinning storm that has been shrinking over the past few decades. 

Space is extremely quiet

Space is completely silent because there is no way for sound to travel. However, astronauts can communicate using radios because radio waves can travel. 

Space junk

Space junk can be dangerous because a collision could trigger a chain reaction of objects hitting each other, creating a thick cloud of debris.
