New research expands the pool of habitable worlds to include super-Earths with hydrogen-rich atmospheres.
Has the Sun entered a stage of old age?
Why isn't there an endless variety of planets in the universe? An astrophysicist explains why planets only come in two flavors.
We may be able to send microchips to investigate Alpha Centauri c up close.
NASA scientists have discovered a new planet orbiting around a nearby star that is in a habitable zone. But does this planet have liquid oceans that can support life?
Scientists can't expect the unexpected if they're not open-minded about how their theories might be wrong.
Sometimes it is difficult to take a photograph of an exoplanet because the star illuminating it is too bright. Now there is a new 'deluminator' telescope that can block out the extra light.
New research suggests that Earth's oxygenation didn't require difficult and complex evolutionary leaps forward.
From the subatomic to the cosmic, don't think for a second that we're at the end of scientific history.
Somewhere out there, just maybe, an alien – probably stranger looking than in our wildest imagination – might be pondering this very question.
Beyond the outer edge of the Solar System, mysterious, unknown worlds await by the thousands. Astronomers can now finally find them and explore them - but will we find another Earth?
Michel Mayor and Didier Queloz thought it would take years to find a planet outside the solar system – they did it in months.
The 2019 Nobel Prize in Physics went to a cosmologist who helped unlock the secrets of the Big Bang's aftermath, and two astronomers who found a "hot Jupiter" orbiting a nearby star.
Scientists who discovered planets in far off stellar systems and the fundamentals of the Big Bang Theory have earned the 2019 Nobel Prize in Physics.
The discovery of a huge planet orbiting a small star challenges our understanding of planet formation.
K2-18 b is now the exoplanet most likely to be habitable.
The geological and biological archives of the Earth shed light on both the distant past of our planet and allow us to imagine its future.
It is always exciting to discover new planets beyond our Solar System. Now a planetary astrophysicist is using a star's chemistry to predict which ones are likely to host giant planets.
Astronomers have found the first observational evidence for a disc of material around a giant young planet at a distant star. It's a place they think moons can form.
Science is full of surprises. While searching for planets orbiting nearby stars, researchers stumbled across the remains of a star that once outshone the Sun.
