New research suggests there may be another planet in the galaxy where living things can survive.

NASA researchers say they have located a planet the size of Earth that could sustain life.

The planet, called Kepler 186F, is slightly bigger than Earth and may support liquid water.

It was spotted by scientists using NASA’s Kepler Space Telescope.

Experts believe it is made of iron, rock, ice and liquid water; the same materials as Earth.

The planet circles a red dwarf star about 490 light years away.

The star is cooler than the sun, meaning the planet is also a bit colder than Earth.

NASA says it is the first definitive Earth-sized planet in the habitable zone of another star.

However, we may never know the truth about the planet.

Experts say it is too far away for astronomers to determine its mass or whether it is home to any living creatures.
