Two 'super-Earth' planets in Goldilocks zone have been discovered, one of which could potentially support life

TWO Earth-like planets have been discovered in outer space, one of which may have the required circumstances for life to evolve. The planets are known as LP 890-9b and LP 890-9c, and they exhibit many of the important characteristics that astronomers look for when searching for life in the universe. Both are stony, terrestrial planets with a hard surface that are devoid of gases. Their host system is the second coldest star with planets in orbit, and NASA refers to it as a "Goldilocks star" because its constant, relatively temperate emissions are suitable for lifeforms. Finding a planet that has many of the similar circumstances as Earth is a momentous cosmic finding; one of the worlds meets even more exact specifications for producing and sustaining life. LP 890-9c is located in its host star's "habitable zone." “The habitable zone is a concept under which a planet with similar geological and atmospheric conditions as Earth, would have a surface temperature allowing water to remain liquid for billions of years,” said Amaury Triaud, professor of Exoplanetology at University Birmingham and leader of the research. “This gives us a license to observe more and find out whether the planet has an atmosphere, and if so, to study its content and assess its habitability.” LP 890-9c is 40% larger than Earth and completes an eight-and-a-half-day orbit around its host star. According to a press release from the University of Birmingham, the James Webb Space Telescope could be useful in observing the atmosphere of LP 890-9c. “It is important to detect as many temperate terrestrial worlds as possible to study the diversity of exoplanet climates, and eventually to be in a position to measure how frequently biology has emerged in the Cosmos,” Professor Triaud said. Because of the great distance between the LP 890-9 system and Earth's telescopes, our observations took place 100 million years ago. Light from a star that no longer exists may have travelled millions of kilometres to reach our space observatories.
