What we found when we went looking for another Earth
Vox・2 minutes read
Scientists aim to find Earth-sized planets in Earth-like orbits around sun-like stars with thin atmospheres and water oceans, exploring the concept of alien life that has gained popularity through media. Research has confirmed exoplanets around sun-like stars, near stars like Proxima Centauri and in systems like TRAPPIST-1, with the James Webb Space Telescope set to further study these planets for potential habitability and signs of life.
Insights
- Discovering an Earth-sized planet in an Earth-like orbit around a sun-like star with a thin atmosphere and water oceans is the primary goal of exoplanet research.
- The James Webb Space Telescope, launched in 2021, will provide detailed insights into exoplanet atmospheres, with a focus on investigating nearby stars and known exoplanets for potential habitability and life support.

"Exploring Earth-like Exoplanets for Alien Life"
- The goal is to discover an Earth-sized planet in an Earth-like orbit around a sun-like star with a thin atmosphere and water oceans.
- The concept of planets with potential alien life has been around for centuries, becoming mainstream in the 20th century through books, movies, and TV.
- Scientists confirmed the existence of the first exoplanet around a sun-like star in 1995, named 51 Pegasi b, which orbits its star in just four days.
- Proxima Centauri, the nearest star to the sun, has an Earth-mass planet in its habitable zone, where liquid water could exist.
- The TRAPPIST-1 system is a favorite, with seven Earth-sized planets, some potentially in the habitable zone.
- The James Webb Space Telescope, launched in 2021, will study the TRAPPIST-1 system, offering more detailed insights into exoplanet atmospheres.
- The focus of current exoplanet research is on targeted investigations of nearby stars and known exoplanets to determine potential habitability and support life.
