Astronomers have discovered seven Earth-sized exoplanets in another solar system.

Six of them are in what’s called the temperate zone, which is an area where the temperature is thought to be between 0 and 100 degree Celsius.

The researchers say that all seven could potentially support liquid water on the surface, depending on the other properties of those planets.

Three of the exoplanets were discovered moving around a star. After making this discovery, astronomers monitored the exoplanets from earth and space and discovered four more.

What is an exoplanet?
Exoplanets are planets that obit a different star than our Sun – in a different solar system to the one we are in.
Even though scientists thought for a long time that they must exist, it was only in 1992 that the first exoplanet was discovered.

Space experts say exoplanets are really important because they raise the possibility that other life could exist in other solar solar systems.

  1. I think it is crazy exciting that there are seven other earth sized planet with all most like earth maybe we might live there on one of those planets like earth.

  2. The fact that such an irrelevant discovery like this is important enough to have an article written on this genuinely tickles me. We’d need a colony ship capable of sustaining human society for between a few dozen and hundreds of years that travels at 99.99% of the speed of light to colonise it, and even then they probably can’t support human life.
