How do space telescopes detect and study exoplanets?

Space telescopes play a crucial role in the detection and study of exoplanets, planets that orbit distant stars beyond our solar system. Astronomers use various methods to gather valuable data about these alien worlds.

Detection of Exoplanets

Space telescopes employ different techniques to detect exoplanets. One common method is the transit method, where telescopes observe a slight dimming of a star's light as an exoplanet passes in front of it. Another method is the radial velocity technique, which detects the wobble of a star caused by the gravitational pull of an orbiting planet.

Studying Exoplanets

Once an exoplanet is detected, space telescopes are used to study their characteristics. By analyzing the light that passes through the exoplanet's atmosphere during a transit, astronomers can determine its composition and even search for signs of life. Additionally, telescopes can measure the planet's size, temperature, and orbital characteristics.

Advancements in Astronomy

Through telescopic observations from space, astronomers continue to make groundbreaking discoveries about exoplanets and their potential to harbor life. Space telescopes have revolutionized our understanding of the universe and expanded the frontiers of space exploration.
