Our galaxy's most abundant type of planet could be rich in liquid water due to formative interactions between magma oceans ...

In the beginning, when planets were newborn, they glowed like furnaces, vast oceans of molten rock wrapped in heavy blankets ...

Scientists found two Earth-sized planets and a third candidate orbiting a nearby double star system, TOI-2267.

New experiments show young rocky planets can generate water naturally when molten surfaces react with hydrogen in their early atmospheres.

Tests on olivine hint that water-rich exoplanets could generate H2O internally, possibly explaining ocean worlds and even some of Earth’s early water.

White dwarfs are the dense, slowly cooling remnants left behind when stars like the Sun exhaust their nuclear fuel. They no ...

Astronomers have discovered the earliest seeds of rocky planets forming in the gas around a baby sun-like star, providing a precious peek into the dawn of our own solar system. It’s an unprecedented ...

When evaluating possible planets out of the thousands out there, explained Prof. Bean, scientists look for liquid water as a main guiding principle. “All life on Earth needs liquid water, no matter ...

(CNN) — Astronomers have confirmed the discovery of the nearest rocky planet outside of our solar system. The planet orbits a star in another solar system about 21-light years away. It cannot be seen ...

In approximately 5 billion years, the sun will deplete its hydrogen fuel and collapse under its own gravity, becoming a white ...
