The discovery boosts the chances of finding extraterrestrial life.

Our rocky planet sister?

While a planet can orbit around a Sun-like star and sit comfortably within its habitable zone, it could also potentially not meet any of the fundamental requirements for sustaining life. Specifically, ...

The search for life beyond Earth has marked a new discovery — evidence of an atmosphere on an Earth-like planet beyond our Solar System with modelling suggesting it may be a water world.

Scientists made a first-of-its-kind discovery: key ingredients for life detected on a habitable-zone planet, upending ...

In a major milestone in the search for life on other planets, astronomers have detected, for the first time, an atmosphere ...

Rocky planets like our Earth may be far more common than previously thought, according to new research published in the journal Science Advances. It suggests that when our solar system formed, a ...

Researchers have found an Earth-like, rocky planet orbiting within the habitable zone of a distant star with an atmosphere.

A newly detected super-Earth just 20 light-years away is giving scientists one of the most promising chances yet to search for life beyond our solar system. The discovery of the exoplanet orbiting in ...

Spotting Earth-like planets is nearly impossible with conventional telescopes, but researchers propose a bold fix: a rectangular design that can separate a planet’s faint glow from its blinding star.

Finding Earth-like planets orbiting sun-like stars and identifying signs of life such as oxygen or water is a major goal in astronomy and a key interest for the public. Addressing this challenge ...

Three decades ago, in 1995, humankind discovered the first planet beyond the borders of our solar system. It's called 51 Pegasi b, and it spins around its main-sequence star (meaning not unlike our ...
