In a breakthrough, researchers have found a new revolutionary method that will help in identifying the existence of alien life on the distant planets and stars. The new method measures surface gravity of the distant planets. Astronomers believe that by measuring gravity at the surface, they could determine body weight at the surface of distant star which will give them a better idea whether the planet can support life or not.
Astronomers say, they might not find aliens in future but still they have invented a new method and using it researchers can determine gravity at the surface with an accuracy of four percent. The technique depends on mass and radius of the planet and then researchers can calculate surface gravity using the derived formula. Later, by comparing the data with the values on Earth, astronomers can tell if the planet can support life or not.
It is far better than the previous techniques that give data with less than 1 percent accuracy. “If you don’t know the star, you don’t know the planet. The size of an exoplanet is measured relative to the size of its parent star,” said study co-author and professor Jaymie Matthews from the University of British Columbia.
The team of astronomers gave a new name to their method — “autocorrelation function timescale technique”, or ‘timescale technique’ in short. Their next aim is to identify planets in the goldilocks zone and then check if the planet has necessary ingredients to harbour life.
Goldilocks zone is a range of distance between the Sun and the planet which is neither too far nor too close where water can exist liquid state. The new study has given a kickstart to the search of alien life. Hope we will succeed finding one someday.
