Nasa finds 17 exoplanets could have oceans of liquid water new study

Scientists are exploring 'exoplanets' in search of life outside the Earth. Such planets which do not revolve around our Sun but around some other star are called exoplanets. In a recent study by the American space agency NASA, 17 exoplanets have been detected. It is estimated that there may be an ocean hidden beneath the ice blocks present in these planets. Scientists around the world have discovered hundreds of exoplanets so far, but none of them have been found at a distance from their star where life is possible.

Space.com's report states that life may be possible in liquid oceans present on other planets. Liquid oceans have been confirmed in the moons of Jupiter in our solar system, but if they are present in exoplanets, then missions can be sent in the future to explore the possibilities of life there.

According to NASA, as part of a recent study, its science team calculated the amount of geyser activity on the exoplanet. NASA said scientists identified two exoplanets where signs of liquid eruptions could be detected beneath the ice blocks. NASA discovered a total of 17 exoplanets where worlds may exist under ice.

The study also revealed that these exoplanets are approximately the size of Earth, but less dense and colder. This shows that their surface is covered with ice. Scientists have made special mention of two exoplanets – 'Proxima Centauri b' and 'LHS1140 b'. He says that the geyser activity there can be several thousand times more than that of Jupiter's moon Europa.

But more study is needed to find out whether life can actually be possible in these places.
