What we found when we went looking for another Earth
Vox・1 minute 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.
