A recent study led by researchers from the University of Toronto reveals intriguing findings about planet K2-18b, located approximately 110 light years away. Data from the European Southern Observatory (ESO) has been instrumental in this discovery.
Two independent research teams, including one led by Angelos Tsiaras from University College London, have detected water vapour in K2-18b's atmosphere. This discovery opens possibilities about the planet's composition and potential habitability.
K2-18b is significantly larger than Earth, with dimensions approximately 2.37 times greater and a mass approximately 8.92 times higher.
This "Super Earth" orbits a red dwarf star, completing one orbit in approximately 32.9 days. Its distance from the star suggests the potential existence of liquid water on its surface.
Despite its potential habitability, reaching K2-18b poses significant challenges. Conventional rocket propulsion methods would require a journey spanning over a million years, presenting a major obstacle for future exploration.
While scientists have gathered some data about K2-18b, there is still much to learn. Limited information about its characteristics leaves room for speculation and further investigation.
Scientists are uncertain whether K2-18b is tidally locked, meaning one side permanently faces its star. This phenomenon could create distinct day and night sides on the planet.
The study of K2-18b offers valuable insights into the search for alien life beyond our solar system. Its unique characteristics and potential habitability make it an intriguing subject for further exploration and research.
