Explainer: Telescopes see light — and sometimes ancient history
Different kinds of telescopes on Earth and in space help us to see all wavelengths of light. Some can even peer billions of years back in time.

Here’s why ducklings swim in a row behind mom
Baby ducks save energy by surfing their mother’s waves, but only if they do it in an orderly line.

Let’s learn about light
Light is a form of energy that moves in waves. Some light comes in waves we can see. Other waves are invisible to us — but still affect our world.
