Summary

Story summary

Thirty years ago, Swiss astronomers identified the first exoplanet around a Sun-like star, yielding over 6,000 exoplanets to date.
Systems include Proxima Centauri with potentially habitable Earth-sized planets and TRAPPIST-1 with seven Earth-sized worlds.
The Vera C. Rubin Observatory will enhance Kuiper Belt observations and could confirm Planet Y, a body inferred from Kuiper Belt orbits.

History

Historical Context

In 1992, astronomers Aleksander Wolszczan and Dale Frail confirmed the first exoplanet orbiting a pulsar, PSR B1257+12, marking a significant milestone in astronomy. This discovery paved the way for over 6,000 exoplanets identified to date, including potentially habitable systems like Proxima Centauri and TRAPPIST-1, enhancing our understanding of the universe and the possibility of life beyond Earth.
