Astronomers are using powerful telescopes to study distant planets that may have conditions suitable for life, but they have not found another Earth or confirmed alien life.
People have asked a big question for a long time: Is there life beyond Earth?
Today, scientists are looking for planets outside our solar system. Some of these planets may be habitable. This means they may have conditions that could support life.
Scientists look for important signs. A planet may need liquid water, a stable atmosphere, and temperatures that are not too hot or too cold.
These planets are very far away, so scientists cannot visit them. Instead, they use powerful telescopes. The telescopes study light from distant stars and planets.
Scientists have already found thousands of planets outside our solar system. Some of them are interesting, but finding a habitable planet does not mean life has been found.
Researchers still need more evidence. They want to study the air around these planets and look for chemicals that may be linked to life.
Even if scientists do not find another Earth soon, the search helps them learn more about planets, stars, and life itself.
