Whether you imagine aliens as friendly beings, like E.T., or something a bit scarier (think “Signs”), the thought of life on other planets is interesting. Could there really be other life in the universe? Scientists think it’s likely.
In recent years, scientists have discovered many stars that have planets orbiting around them. There are probably many more out there yet to be discovered. Chances are, at least some of these stars might have planets like Earth.
The Kepler telescope, launched in 2009, is looking for planets like Earth. So far, it has found more than 2,700 possible planets. A few of them are similar to Earth.
Fun Facts about Life on Other Planets for Kids
- Scientists are looking for three things: a planet with gases like oxygen and carbon dioxide that support life; a planet with water and a planet that’s not too cold or too hot.
- The Kepler telescope’s most exciting discovery was the planet Kepler 22b. This planet is a little larger than Earth, but it is about the same distance away from its star as the Earth is from the Sun. Scientists believe it might have water on it.
- The Kepler telescope is currently broken. Scientists hope they can fix it. If they can’t fix it, the project will be over.
- Life on other planets probably won’t look like the aliens you see in movies. Chances are, it might look more like bacteria, which can survive hostile conditions and hot and cold temperatures.
