More than 5,000 exoplanets orbiting other stars in outer space have been identified.
According to CNN broadcasts, etc., on the 21st (local time), the National Aeronautics and Space Administration (NASA) announced that 65 new exoplanets were added to the exoplanet archive, and the number of exoplanets confirmed through space telescopes and artificial satellites was counted as 5005. It has been 30 years since NASA first discovered exoplanets in 1992.
Each exoplanet has different characteristics. Earth-like planets and rocky planets such as Mars make up only 4% of the total. Some exoplanets orbit more than one star, and some exoplanets orbit white dwarfs called dead stars.
The study of exoplanets is meaningful in finding the answer to the oldest question in astronomy regarding the origin of the universe and how we got here from the Big Bang (big explosion) 13.8 billion years ago. In particular, the James Webb Space Telescope (JWST), the next-generation space telescope launched in December last year, is expected to discover more exoplanets.
