NASA DISCOVERS NEW PLANET
scientists have developed a metric known as the Earth similarity index which measures the similarity of a planet or moon to earth based on various parameters such as temperature atmospheric pressure and habitability it ranges from 0.0 to 1 with 0.8 and 1 indicating that a planet is similar to Earth in every aspect in recent years advances in technology allowed us to uncover a multitude of exoplanets and moons with striking similarities to Earth one of them was found in 2019 and called Tea Garden B this is a super Earth orbiting an m-type star every 4.9 days at a distance of 0.0252 AU the Tea Garden star is one of the closest stars to our solar system located about 12.4 light years away from us and although the Red Dwarf is 10 times less massive than our sun and has a temperature of just about 2700 degrees Celsius it can still provide enough heat for its two planets the two exoplanets are similar to the inner planets in our solar system and are only slightly more massive than Earth both of them are situated in the habitable zone where liquid water can exist but tea garden B seems much more promising and here`s why Tea Garden B has been given a score of 0.95 ESI meaning it`s the most Earth-like planet discovered so far there`s a 60 probability that the exoplanet has a temperature surface environment with temperatures ranging from zero degrees to 50 degrees Celsius and if its atmosphere is comparable to Earth`s the surface temperature would likely be around 28 degrees Celsius Tea Garden sea however is farther from its star it has a 0.68 ESI score and only a three percent chance of having a warm surface temperature if this world`s atmosphere is more similar to that of Mars its estimated temperatures would be around -47 degrees Celsius researchers are not sure what the atmospheres of the two planets are but tea garden B and C are tidally locked to their star and a thin atmosphere could distribute heat and cold across the dark and light dividing line scientists estimate that atmospheres with densities between 1 3 to 17 times out of Earth`s could allow for liquid water to be present on the surface but that's not all there's a planetary system that offers some of the best candidates for extraterrestrial life and the discovery of its most promising candidate has just been announced the tli 700 planetary system is known to have at least four planets two of which are in the star's habitable zone the most promising are toi 700e and toi 700d both being Rocky and having similar masses to Earth toi 700e has an orbital period of 28 days and is 95 percent the size of Earth while toi 700d has an orbital period of 37 days and is 105 the size of Earth the toi 700 system has been around for more than 1.5 billion years giving more than enough time for biological activity to take hold and transform the thin region where the planet's surface meets its atmosphere into a rich biosphere if toi 700e and toi 700d have an atmosphere they would be much warmer than Earth's average temperature a potential Game Changer in terms of habitability scientists suspect that there could be more planets located Beyond toi 700d and if one day we were to discover life forms on any of these worlds we likely hope that they resemble those found here on Earth but is it theoretically possible that similar life forms could exist on other planets evolution is considered a universal law of nature just like gravity because of this the principles of evolution found on Earth can be applied to other planets due to the process called evolutionary convergence where unrelated species can evolve similar adaptations to similar environmental challenges the starting point of life on any Alien Planet must be simple and on many of them it could have remained like that but if some of these worlds develop complex forms of life it could have only
