Gliese 12 b, which orbits a cool, red dwarf star located just 40 light-years away, promises to tell astronomers more about how planets close to their stars retain or lose their atmospheres. In this ...

A 2020 microlensing event was caused by a planetary system with an Earth-like planet and brown dwarf. The star type was uncertain. The team has determined that the star is a white dwarf, a system ...

When it comes to directly imaging Earth-like exoplanets orbiting faraway stars, seeing isn’t always believing. A new Cornell University study finds that next-generation telescopes used to see ...

The hunt is on for a second Earth, somewhere out there in the Milky Way galaxy, but a newly discovered world is not quite the thing. It comes in at around 1.9 times the mass of Earth, orbiting its ...

Images of the area of the microlensing event, indicated by perpendicular white lines, years before the event (a), shortly after peak magnification of the background star in 2020 (b) and in 2023 after ...

The future of the planet may not be the most comfortable of subjects to think about — from the threat of climate change to worry about world wars — but for astronomers, it's something to consider when ...

Scientists have found a new Earth-like planet that could support alien life – just 40 light-years away. The planet is a remarkable discovery in the search for habitable worlds: it is slightly smaller ...

A rocky planet in the Milky Way galaxy may have an atmosphere, raising the possibility that life could exist on its surface, according to experts. TRAPPIST-1e, a planet belonging to a collection of ...

— -- Astronomers on Monday reported the discovery of an Earth-like planet outside the solar system whose size and distance from its own star put it in the "habitable" zone and make for a surface ...

JWST observations of exoplanet TRAPPIST-1d reveal a lack of a substantial, Earth-like atmosphere, as indicated by a "flat" spectral signature lacking typical atmospheric molecule fingerprints (e.g., ...

An international team of astrophysicists has discovered a new planet five times the size of Earth, the smallest extrasolar planet revealed to date outside of our solar system. Using a network of ...
