Exoplanet climate 'decoder' aids search for life

After examining a dozen types of suns and a roster of planet surfaces, Cornell University astronomers have developed a practical model—an environmental color "decoder"—to tease out climate clues for potentially habitable ...

Earth's moon may not be critical to life

The Moon has long been viewed as a crucial component in creating an environment suitable for the evolution of complex life on Earth, but a number of scientific results in recent years have shown that perhaps our planet doesn't ...

Webb reveals steamy atmosphere of distant planet in detail

NASA's James Webb Space Telescope has captured the distinct signature of water, along with evidence for clouds and haze, in the atmosphere surrounding a hot, puffy gas giant planet orbiting a distant Sun-like star.

Seeing the Closest Aliens Will Take Centuries

As telescopes become more advanced, we’ll be able to see more details about planets orbiting other stars - including indications that those planets have life. However, it would probably take many centuries before we could ...

A new way to characterize habitable planets

For decades, science fiction authors have imagined scenarios in which life thrives on the harsh surfaces of Mars or our moon, or in the oceans below the icy surfaces of Saturn's moon Enceladus and Jupiter's moon Europa. But ...

The space weather forecast for Proxima Centauri B

Proxima Centauri, the closest star to the Earth (only 4.28 light-years away) is getting a lot of attention these days. It hosts a planet, Proxima Cen b, whose mass is about 1.3 Earth-mass (though it could be larger, depending ...
