Penguin census from space

Scientists are using satellite mapping technology to count penguins in Antarctica. The latest results have shown that there are actually twice as many emperor penguins there as previously thought. Isn’t it nice when you hear some good news for a change?

The information provides a more accurate basis for researchers to monitor how environmental change is affecting the penguins.  Satellite photography is proving to be a great way of keeping track of the penguins because their black and white feathers stand out against the snow, so the colonies are clearly visible on satellite imagery.
