A team of astronomers claims to have sniffed out a “biosignature” in the atmosphere of a distant planet called K2-18b. But ...

The exoplanet K2-18b could harbor a massive ocean, but scientists will need to study the planet more to see if it’s really likely to host life.

A bold geochemical model reveals that TOI‑270 d, a sub‑Neptune 73 light‑years away, is likely a giant rocky world cloaked in a blistering, dense atmosphere rather than a watery Hycean planet. Webb ...

K2-18b, an exoplanet 120 light-years away, may be the best hope to confirm that life exists beyond Earth. Here's what to know.

NASA has discovered a new world, named Gliese 12 b. It is roughly the size of Earth, lies in the habitable zone, and orbits every 12.8 days.

NASA recently tracked asteroid 2024 YR4, which initially showed a 3 per cent chance of hitting Earth in 2032. New data shows it's no longer a threat, but the incident highlights the need for strong ...

NASA is closely monitoring a building-sized asteroid as it makes its closest approach to Earth today, among a group of five other space rocks passing by our planet over the next two days. The asteroid ...

All that said, the findings can’t confirm the terrestrial life theory beyond a doubt. There’s still a chance hydrogen-heavy ...

To study Mars’s chemical and mineral makeup, the Curiosity rover drills one to 1.5 inches down into the subsurface, then ...

The Trappist-1 system, just 40 light years from Earth, contains 7 rocky planets—all roughly the size of Earth. Packed tightly within the space between Mercury and the Sun, three of these planets lie ...

A new study ... alien planet. With molecules like carbon dioxide, methane and water detected, we could start doing some geochemistry to learn how this unusual world formed." NASA's JWST detected ...

Further studies are needed to determine whether K2-18b, which orbits a star 120 light-years away, is inhabited, or even ...
