Telescopes Search for Life Beyond Earth
Scientists are using big telescopes in space to look for signs of life on planets outside our solar system.
These planets are called exoplanets.
They study the air around these planets to see if they have gases that could mean life is there.
One telescope, called JWST, has found some gases like methane and water on a planet called K2-18b.
But some scientists think this finding might not be correct.
There are more telescopes planned to launch in the next few years that will help us learn even more about these distant planets.
This could help us answer one of the biggest questions: Is Earth the only place with life?
Scientists are using telescopes to analyze the atmospheres of exoplanets for signs of life.
The James Webb Space Telescope (JWST) has detected molecules like methane, carbon dioxide, and water on exoplanets.
A controversial detection of dimethyl sulphide on K2-18b, possibly indicating life, has been disputed by other researchers.
Upcoming missions like Plato (2026), Roman (2029), Ariel (2029), and HWO will enhance our ability to study exoplanet atmospheres.
Future telescopes may be able to map the surfaces of Earth-like planets and detect signs of photosynthesis.
