Researchers have developed a new technology that can shape the spectrum of light emitted from a laser frequency comb across the visible and near-infrared wavelengths with more precision than ...

One of the boldest dreams in modern astronomy is the search for Earth-like worlds beyond our solar system. These exoplanets may hold oceans, rocky ground, and even atmospheres rich in oxygen or ...

One of the worlds in the TRAPPIST-1 system, a mere 40 light-years away, just might be clad in a life-supporting atmosphere. In exciting new JWST observations, the Earth-sized exoplanet TRAPPIST-1e ...

A newly identified planet candidate, HD 137010 b, looks strikingly Earth-like in size and orbit — but it may be colder than Mars due to its dimmer star. If it has a thick enough atmosphere, though, ...

In a blow to anyone dreaming that complex life may exist elsewhere in the universe, a new study suggests we're unlikely to find it around many of the most common stars in the galaxy. A new study led ...

WASHINGTON - European astronomers say that just outside our solar system they've found a planet that's the closest you can get to Earth in location and size. It is the type of planet they've been ...

Astronomers have identified the most Earth like exoplanet yet, orbiting a sunlike star in the habitable zone 1,400 light years away. It is a snapshot of how far the search for life has come, and how ...

Astronomers are actively searching for Earth-like planets, with thousands of exoplanets now confirmed. While Proxima Centauri b is the closest rocky planet in a habitable zone, its true Earth-likeness ...

The planetary system, located 120 light-years away, features four worlds orbiting a red dwarf star and challenges classical formation schemes.

It was almost 100 years ago that Clyde W. Tombaugh discovered Pluto. That was the last planet found until 1992, when humans found another one. But this new planet wasn't in our solar system—it was ...
