Environmental research and Genetic Expression in New Earth Similarity study

摘要

With the recent launch of space mission like CoRoT, Kepler Mission, K2 Kepler mission, Terrestrial Path Finder and upcoming James Web Telescope there is a high increase in enthusiasm to search exoplanets and astrobiology field has boomed and fascinated researchers in search of life on other exoplanets. Till date, more than 3800 exoplanets have been discovered. With the generation of heavy data of exoplanets, it's a peak time to channelize the database. Here team has provided with similarity indexing not only based on planetary readings but also compared it with the extremophile," tardigrade" a multicellular organism which is capable of going in desiccation i.e. tun formation on extremities and returns back to the normal state on favourable conditions and also been tested against vacuum pressure and radiation in space. Not only this, as per discovery by Hashimoto et al 2016 tardigrade proteins could be used with the human genome to obtain protection from radiation. The team has provided Habitability Index (HI) as the geometric mean of Terrestrial Similarity Index (TSI) and Extremophile Sustainability Index (ESI), where the physical parameters mean radii, bulk density, Escape velocity, orbital period, Surface pressure, Surface temperature and newly added component Impact parameter were used to analyse.
