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.

Stars made of antimatter could lurk in our galaxy
Fourteen sources of gamma rays in our galaxy look like they could be antistars — celestial bodies made of antimatter.

Light levitation might help explore Earth’s ‘ignorosphere’
A toy called a light mill inspired researchers to invent a new way to fly. They’re using light to levitate small nanotube-coated discs.

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.

Understanding light and other forms of energy on the move
Radiation needn’t be scary, especially if it allows us to see our family or use our cell phones. Here’s a guide to light and other types of emitted energy.

Spotted: Milky Way’s giant gas bubbles in visible light
The bubbles have different colors, based on how the gas inside them moves. That could give clues to how the bubbles developed.
