We have only imagined “aliens” in books and movies without actually knowing whether there is life beyond earth also. It is more of our fascination than reality. But if the recent report from NASA is to be believed then the time is not far when we will be able to actually communicate with aliens. The Kepler spacecraft has given us hope about the same.
300 million habitable worlds!
The Kepler spacecraft that was part of the mission of planet-hunting stayed in space for nine years. In 2018, it ran out of fuel but the evidence it had collected gives us high hopes about the presence of life on other earth-like planets. The data revealed by NASA suggests that there can be at least 300 million earth-like planets in our galaxy that can have a life expectancy. It means that these planets must have liquid water support on their rocky surface.
NASA researchers predictions
The Ames research center of NASA reported that “Some of these exoplanets could even be our interstellar neighbors, with at least four potentially within 30 light-years of our Sun and the closest likely to be at most about 20 light-years from us. These are the minimum numbers of such planets based on the most conservative estimate that 7% of Sun-like stars host such worlds. However, at the average expected rate of 50%, there could be many more.”
As the data collected by Kepler was used by some unknown sources, Nobel laureate physicist Murray Gell Mann predicted that “Somewhere, on some other planet orbiting some very distant star, maybe in another galaxy, there could well be entities that are at least as intelligent as we are, and are interested in science. It is not impossible.” If these predictions from the scientists are true then it is possible that there is life beyond earth.
The hope continues
With these essential resources and information, the hope to see the presence of life other than earth sparks high. With so many researchers going berserk over the discovery of life beyond earth, this simple survey has once again added fuel to the fire. We are hopeful that more such research will be carried out in the future to find out about life expectancy in other planets.
The PolicyTimes suggestion
- It is good news that NASA scientists have found the existence of life beyond earth. If there is any chance of having life on other planets then it can instigate better research opportunities in the future.
- The Indian space researchers from ISRO must also make attempts to reach out to such habitable planets where the chances of life still remain high. If they can achieve the height to send a spacecraft to mars successfully then it is evident that they have the potnstial as good as NASA researchers.
