Astronomers have detected helium escaping from the super-Earth LHS 1140 b, providing the strongest evidence yet that a rocky planet in another star's habitable zone has retained an atmosphere for ...

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

A rocky exoplanet 48 light-years from Earth has offered the 'strongest evidence yet' that other planets besides Earth could be hospitable to life.

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.

A group of three potentially habitable planets orbiting a star known as Trappist 1 have been discovered by scientists. Their similarity in size and temperate to that of the Earth and Venus suggest ...

When astronomers discovered the first planet outside our solar system, it was orbiting a pulsar, one of the most extreme, radiation-blasted environments imaginable. Not exactly the kind of place you'd ...
