A study led by Dirk Schulze makuch, a geobiologist at Washington State University (WSU), was published in Astrobiology last month, foreign media CNET reported. The paper identified more than 20 exoplanets that may be “super livable” worlds more suitable for life than our own. < / P > < p > researchers have created a set of criteria for planets to meet the potential for super habitability. This list includes the liquid ages of the stars (between 5 billion and 4.5 billion years old), and the likely existence of water in the earth’s region of about 4.5 billion years. They also looked for long-lived stars that are cooler than our sun. < / P > < p > instead of focusing on “clones” of the earth, the team is looking for planets larger than our own. “A planet with a mass of about 1.5 times the mass of earth is expected to retain its internal heating for a longer time by radioactive decay, and will also have stronger gravity to retain its atmosphere for a longer time,” the team said in a statement on Monday. < / P > < p > the team applied the criteria to 4500 known exoplanets and identified 24 closest to meet the requirements. Although none of them meets all the requirements, they imply the possibility of a life friendly world outside our own. < / P > < p > when it comes to these potential paradise, there are many unknowns. “Habitability doesn’t mean that there must be life on these planets, it’s just conditions that are conducive to life.” Washington State University researchers said. A bigger problem is that these candidate planets are more than 100 light-years away, which means they are too far away. < / P > < p > “we have to focus on some of the planets that have the most promising conditions for complex life,” Schulze makuch said. “However, we must be careful not to get caught up in the search for a second earth, as there may be planets that are more suitable for life than our own.” Global Tech
