Astronomers Confirm Over 6,000 Exoplanets Beyond Our Solar System
Scientists have found over 6,000 planets orbiting stars other than our sun, called exoplanets.
This discovery, which started about 30 years ago, is a huge step in finding out if we're alone in the universe.
Telescopes like Kepler and TESS help us find these planets by watching how stars' light changes.
Some exoplanets are similar to Earth, while others are very strange, like planets with oceans of lava or skies with gemstone clouds.
Scientists hope to use powerful telescopes to study the atmospheres of these planets to look for signs of life.
The discovery pace is accelerating with more missions planned to search for Earth-like planets.
Astronomers have confirmed the existence of over 6,000 exoplanets.
Thousands more exoplanets are waiting to be verified.
The first exoplanet was discovered in 1992.
Modern space telescopes are key to discovering new exoplanets.
Scientists are searching for potentially habitable worlds.
