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?

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 ...

For years, some exoplanets looked like good bets to have water, some with deep global oceans. They sit between Earth and Neptune in size, and several early spectra hinted at water friendly chemistry ...

NASA’s James Webb Space Telescope made a groundbreaking discovery on exoplanet K2-18b. Scientists say they may have detected signs of life in its atmosphere. This could change how we see the universe ...

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 ...

Since astronomers found the first planets outside our solar system in 1992 and the first planet around a sunlike star in 1995, scientists have sought the telltale glimmers, flickers and wobbles that ...

Astronomers might be close to confirming the presence of an Earth-like atmosphere on an exoplanet for the first time, if more detailed analyses verify preliminary observations from the James Webb ...

Science fiction writer and futurist Arthur C. Clarke once said, “Two possibilities exist: either we are alone in the universe or we are not. Both are equally terrifying.” And perhaps that fear is what ...
