Instrumental Space Observations
The ability of TESS to detect exoplanet transits provides invaluable insights into the characteristics of distant worlds, significantly advancing our understanding of planetary systems beyond our own.
Investigative Endeavours
Efforts are underway to probe Gliese 12 b's atmosphere, aiming to shed light on its habitability. Current observations suggest the possibility of a relatively thin atmosphere, yet further study is required to ascertain its composition.

Red Dwarf Environment Insights
The study of planets orbiting red dwarf stars like Gliese 12 offers a unique glimpse into the dynamics of planetary systems surrounding the most common stellar type in our galaxy.
Balancing Prospects and Challenges
While red dwarfs present extended lifetimes conducive to life's emergence, they also pose potential hazards, including intense flares that could strip away planetary atmospheres, impacting habitability.
A Promising Beginning
Gliese 12 b represents a significant milestone in humanity's quest to explore the potential for life beyond Earth. Continued research and exploration in exoplanetary science hold the key to unlocking the mysteries of distant worlds and the prospects they may harbour.
