On Earth, water is so intertwined with life that our search for life on other worlds is essentially a search for water. When ...

NASA's James Webb Space Telescope has uncovered evidence of a possible ocean world larger than Earth with conditions that have the potential to support life.. The exoplanet known as K2-18 b was ...

For years, scientists have speculated about the nature of water on exoplanets, especially on super-Earths and sub-Neptunes — planets larger than Earth but smaller than Neptune. The prevailing ...

In addition to 21 rocky planets and seven gassy planets, they found six examples of a new type of exoplanet, watery, which is made of about half-rock and half-water, either in liquid or ice form.

"Water is the first thing we look for when we’re trying to see if a planet is habitable, and there are already exciting observations of water in exoplanet atmospheres.

Astronomers using the Hubble Space Telescope have detected water molecules in the atmosphere of a small, blazing-hot exoplanet 97 light-years from Earth. The planet, named GJ 9827d, is about twice ...

This article was originally published with the title “ Astronomers Find Water on an Exoplanet Twice the Size of Earth ” in SA Space & Physics Vol. 2 No. 6 (December 2019) doi:10.1038 ...

If this "one-of-a-kind" exoplanet were confirmed to be a water world, its ocean would be significantly deeper than Earth's. While our planet is 70% water, oceans account for less than 1% of the ...

Water, which is essential for life as we know it, is said to be common, but unexpectedly scarce on exoplanets. What scientists have found is that many exoplanets have water, but there is less ...

One such source, according to many scientists, would be exoplanets. Many have been thought to contain water, but a new study has confirmed that there may actually be less water on exoplanets than ...

Scientists have detected water vapor in the atmosphere of a “super-Earth” exoplanet with potentially habitable temperatures. The discovery, which is being touted as a milestone, could have ...

It’s unlikely that these exoplanets have a water ice shell, Luque says, because they are much closer to their star–any water on the surface would evaporate. That is, at least, on the sun ...
