Alien life can spy on us from these nine exoplanets: All you need to know

No such Planet Nine exists, reveals scienitists

In the quest of finding out how alien planets or celestial bodies might be able to spot our planet, a group of scientists from Queens University Belfast in the UK and the Max Planck Institute for Solar System Research in Germany have successfully detected that at least nine exoplanets are suitably placed to view the transits of Earth.

The latest discoveries about alien planets being able to detect our Earth has made the scientists and researchers excited, and this will also boost the confidence of the scientists who are continuously and dedicatedly trying to locate those exoplanets that can ideally spot our planet.

Also along with that, some particular areas of the outside world have been located by the research team from where some planets of Solar system can be easily observed passing in front the sun. They said that planets that are more close to the Sun as Mercury, Venus, Earth and Mars, are more likely to be seen than those planets that are away from the Sun.
Robert Wells, a PhD student at Queens University Belfast told that although bigger planets can block more light as they pass in front of their star but the most important thing is how close that planet to its star is. The closer the planet to its parent star, greater is the chance of its visibility in transit. After years of research, scientists have found out that at most three planets could be seen from anywhere outside the solar system.

Katja Poppenhaeger, from the Queens University Belfast, informed that according to their estimation, a randomly positioned observer have a chance of observing at least one planet is 1 out of 40. Then the probability of spotting at least two planets would come down to about ten times lower and finally to detect three planets; the probability becomes ten times smaller.

“The discovery of seven new exoplanets orbiting the relatively close star TRAPPIST-1 forces us to rethink life on Earth,” she said. “It opens the possibility to broaden our understanding of coupled system dynamics and lay the foundations to explore a path to long-term sustainability by entering into a cooperative ecological-evolutionary dynamic with the coupled planetary systems.”

Out of more than 1000 exoplanets, scientists discovered that there are nine such planets which can spot our planet Earth’s transits from outside the Solar system. Scientists also revealed that there might be another ten undiscovered world which could detect our Earth and also might posses life in them. But as of now, there is no evidence of life in those new worlds and planets.

“Any world hosting a long-lived energy-intensive civilization must share at least some similarities in terms of the thermodynamic properties of the planetary system,” they write. “Understanding these properties, even in the broadest outlines, can help us understand which direction we must aim our efforts in developing a sustainable human civilization.”
