Evidence is mounting that the same basic chemistry that made Earth habitable is unfolding, or once unfolded, on Mars. From ...

Astronomers have finally weighed a wandering “rogue” planet, uncovering a Saturn-mass world flung into the galaxy after a ...

Across the Milky Way and beyond, planetary systems appear to fall into a few recurring blueprints, and recent exoplanet ...

— -- 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 ...

A thick atmosphere has been detected around a planet that's twice as big as Earth in a nearby solar system, researchers reported Wednesday. The so-called super Earth — known as 55 Cancri e — is among ...

New research shows how RNA, a key molecule for life, may have formed on early Earth using simple chemistry and materials delivered by asteroid impacts, linking space science with the origins of life ...

Scientists found an intriguing world in our galaxy. They confirmed the existence of a rocky planet, called a "super-Earth," that's some six times as massive as Earth. While the world HD 20794 d is ...

Rockström is a research professor in earth system science at University Potsdam, the director of the Potsdam Institute for Climate Impact Research, and co-founder of the Planetary Guardians. The ...

A new machine learning model has predicted that there are 44 Earth-like planets in other star systems in the Milky Way galaxy, with researchers from Switzerland claiming that the algorithm at the core ...

Astronomers have discovered that "super-Earth" planets may exist on wider orbits than previously thought — and this implies these rocky, or "terrestrial," worlds are far more common than was suspected ...

Plate tectonics give rise to Earth's mountain ranges, earthquakes and the long-term movement of continents, and may even have provided the right conditions for life on Earth. But as far as we know, no ...
