By the name, you might think that a dwarf planet is just a small planet. But that’s not quite true!
Like planets, dwarf planets have a rounded shape and orbit our sun. They don’t orbit anything other than the sun, so they’re not moons. However, there is one major di […]

Thousands of miles beneath our feet, flowing electrons create a powerful force that protects life on Earth. This effect is called a magnetic field. But what creates this magnetic field? Deep, deep below the ground lies center of the Earth, also called its core. It is a place of incredibly high temperatures and pressures. Earth’s […]
With cell phones and the Internet, we’re used to communicating with anyone, anywhere, quickly and easily. But how do scientists communicate with things that aren’t on our planet — such as the Curiosity Rover on Mars? This communication beyond Earth is a bit more complicated.
We communicate with spacecraft using radio signals. Radio signals move at the speed of light. […]
