Not only did we not find water on Earth-like exoplanets, but we couldn't with the current technology

One of the holy grails and modern science is about finding a world, beyond Earth, with life on it.

NASA / Ames / JPL-Caltech

Perhap s most exciting opportunity is to finds a rocky exoplanet with liquid water on its surface and biosignatures in its atmosphere.

NASA Ames / JPL-Caltech / T requires a lot of progress. Pyle

Over the last few decades, astronomers have discovered thousands of new exoplanets.

Some of them are rocky; some are moderate; some have water.

However, the idea that the exoplanet K2-18b is rocky, similar to Earth and has liquid water & nbsp; is absurd, despite the last headlines

NASA / Godard

Light filters through the atmosphere of K2-18b as it passes in front of its star, which allows us to measure what is absorbed.

ESA / David Sing

Based on these absorption lines, the presence of many chemicals can be concluded including water .

K2-18b is indeed the first known habitable zone of the exoplanet zone containing water.

However, it is not rocky; its mass and radius are too large, necessitating a large gas shell around it

Chen and Kipping, 2016 ., via https://arxiv.org/pdf/1603.08614v2.pdf records19659007: 11If his atmosphere was like earthly, it would & nbsp; would be undetectable & nbsp; via & nbsp; current & nbsp; tools.

It's a mini -Neptune: interesting, but not the habitable exoplanet we're looking for.

NASA Ames / N. Batalha and W. Stenzel

That's why we need new, bigger, more sophisticated

Unless we build them, & nbsp; we will never find worlds similar to Earth
