Hycean worlds, which are a possible kind of exoplanet with deep oceans surrounded by a thick envelope of hydrogen, could ...

Finding alien life won’t be as dramatic as a flying saucer landing on the White House lawn – it’ll be NASA scientists holding ...

A recent study published in Astrophysical Journal Letters proposes an unprecedented method for detecting life beyond our ...

Researchers suggest that certain gases detected in the atmospheres of exoplanets could be key indicators in the search for ...

加州大学河滨分校 (UCR) 的天文学家在系外行星的大气中发现了一种新的潜在特征，这可能表明存在生命。这是一组称为甲基卤化物的气体，由一个碳原子和三个与卤素原子结合的氢原子组成。 这是艺术家对一颗 Hycean ...

What can methyl halides, which are gases that consist of one carbon and three hydrogen atoms while being attached to a ...

Hycean worlds, which are a possible kind of exoplanet with deep oceans surrounded by a thick envelope of hydrogen, could provide the best chance for the James Webb Space Telescope (JWST ...

The James Webb Space Telescope could potentially detect signs of life on alien 'hycean' ocean worlds, possibly the most ...

Scientists identify methyl halides as a strong biosignature for alien life, with Hycean planets offering the best chance for ...

HUNTING for aliens is now a little easier as scientists discover a new sign that gives away life on far-off planets. Importantly, this new signal teases the presence of alien life on distant ...

A Hycean exoplanet could have detectable methyl halide gases in its atmosphere that could indicate the presence of life. Credit: Amanda Smith illustration These gases — composed of carbon ...

Instead, JWST would have to aim for larger exoplanets orbiting small red stars, with deep global oceans and thick hydrogen atmospheres called Hycean planets. Humans could not breathe or survive on ...
