Discovery Of Water-Worlds Increases Chances Of Finding Alien Life

A bunch of Harvard Scientists discovered that there are exoplanets that contained extra water than Earth. The scientists stated these water-worlds are larger than our planet, suggesting that they may additionally help life identical to Earth.   ( NASA )

Scientists from Harvard University say one in three of the exoplanets discovered contained extra water than Earth. This suggests they’ll help life identical to planet Earth.

Specifically, 35 p.c of the exoplanets with sizes larger than Earth is discovered to be ample with water, as 50 p.c of their weight is comprised of the colorless liquid. In comparability, Earth’s weight is barely composed of zero.02 p.c of water.

The group believed that these exoplanets, now known as water-worlds, shaped equally with how Jupiter, Saturn, Uranus, and Neptune had been shaped. Since they’re two to 4 instances bigger than Earth, these water-worlds might present the perfect probability of supporting new life, the scientists stated.

The Water-Worlds

For their examine, which was introduced on the Goldschmidt convention in Boston on Aug. 17, the scientists used the information from NASA’s Kepler Space Telescope and the Gaia mission. The group of worldwide consultants analyzed the exoplanets with regard to their mass measurements and radius measurements. The group then created a normal mannequin of the exoplanet’s inside construction.

The mannequin confirmed that these exoplanets with a radius of about 1.5 instances the Earth radius encompass rocks that are about five times the mass of Earth. On the opposite hand, the exoplanets with a radius of about 2.5 instances the Earth’s radius and a mass of round 10 instances that of Earth belonged to the group now known as water-worlds.

Dr. Li Zeng, the lead researcher from Harvard University, said the water in these exoplanets will not be generally discovered on Earth. For one, the water’s floor temperature is predicted to be about 300 to 900 diploma Fahrenheit.

“Moving deeper, one would expect to find this water transforms into high-pressure ices before reaching the solid rocky core,” Zeng defined.

“Life could develop in certain near-surface layers on these water worlds when the pressure, temperature and chemical conditions are appropriate,” she added.


Exoplanets had been found as early as 1992 orbiting round different stars. To date, scientists have discovered 4,000 of confirmed and candidate exoplanets and the curiosity in figuring out whether or not they’re appropriate to develop or help life are rising as ever.

NASA has particularly positioned the variety of confirmed exoplanets at three,700. The company stated there may extra of them, even tens of 1000’s of them. They can also be found as extremely superior and robotic telescopes are deployed into house.

For one, NASA’s newly launched TESS mission goals to search out extra of the exoplanets. NASA’s James Webb Space Telescope, however, goals to characterize the ambiance of those Super-Earths.
