Astronomers have discovered that the exoplanet K2-18b, located 124 light years away in the constellation of Leo, may be one of the most promising candidates for life beyond Earth. With a size more ...

New research suggests that planets outside our solar system contain far less surface water than scientists once believed. Contrary to earlier theories that these exoplanets might be covered by deep ...

Are Hycean exoplanets, which are a combination of hydrogen and a potential liquid water ocean, less common than previously hypothesized? This is what a recent study published in The Astrophysical ...

But those claims were quickly met with pushback. Independent analyses of the same JWST data suggested the team's evidence for DMS was weak at best, while other experts cautioned that sub-Neptunes may ...

Sub-Neptune planets, often billed as possible "water worlds," may be more desert than deep sea, according to a new study. For years, scientists thought these planets, which are larger than Earth but ...

Humans are finally building the technology that could tell us where to look, when to look, and what signs to watch for. What might we find? Why does it matter?

In our solar system, Earth is one of but eight planets – nine, if you really want to count Pluto – and the only one remotely hospitable to life. And as technology advances, astronomers only expect to ...
