Step 1 of 4
- Your eyes alone catch a lot: the Moon, planets, stars.
- A telescope gathers far more light.
- It also spreads a tiny shape out bigger.
- Now the rings are clear.
The rule
A telescope is a tool for seeing far things. It helps your eyes in two ways. It gathers more light. More light makes dim things easier to see. A telescope also makes small things look bigger.
Some sights need a telescope. Saturn's rings and Jupiter's four big moons are examples. So are the Moon's craters. Craters are round dents. Space rocks hit the Moon long ago and made them.
