What's new

The blue sky on Earth is caused by light scattering through air. There’s no air on the Moon, so the sky is always black.

The largest wandering albatrosses have wingspans around 3.7 metres. That’s about the same as 2 adults lying end to end!

True! Mosquitoes are members of the order Diptera (meaning 2 wings), which is the scientific definition of a fly.

Triplanes, such as the Red Baron’s Fokker triplane, stack their wings vertically. This gives them lots of lift, but they can’t go very fast.

During the day, clouds reflect sunlight back out to space, making it cooler. At night, they trap Earth’s heat near the ground, like a warm blanket.
