How Can Satellites Find Penguins From Space?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. How can satellites find penguins from space?

The Big Idea

Satellites can find penguins from space by spotting their droppings! The droppings stain the ice and rocks a reddish brown. That color can be seen from far, far above. Let's zoom in!

Brown Stains

Step one: brown stains. Penguin droppings stain the ice and rocks a reddish brown color. The stains are big enough to see from space, because thousands of penguins crowd together.

Satellite Search

Step two: search the pictures. Scientists look at satellite pictures of Antarctica for these stains. A brown patch on white ice stands out, like spilled chocolate on a tablecloth.

New Colonies

Step three: find new colonies. In this way, scientists found new emperor penguin colonies far from any people. It is a way to count penguins without disturbing them, and without going near the dangerous cold.

A Closer Look

Let's take a closer look! Penguins gather in a big colony to keep warm. Their droppings leave brown stains. A satellite takes a photo from space. Scientists use it to find and count penguins, all from afar.

Quick Facts

Quick facts! Scientists discovered several new emperor penguin colonies using satellite photos. Some colonies sit in places that people almost never visit. Satellites can also watch how sea ice changes from season to season. Look at satellite pictures online with a grown-up.

Think Like a Scientist

Now, think like a scientist! Sprinkle cocoa powder on white paper. View it from across the room. Can you spot a brown patch from far away? Satellites do something similar! Share what you discover with a grown-up.
