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

The gas giant WASP-18b belongs to a class known as ultra-hot Jupiters — giant, searing, gaseous planets that orbit perilously close to their stars. Researchers used a new technique called ...

In a significant breakthrough, scientists have identified three Earth-sized exoplanets in a binary star system, potentially ...

Washington, DC— Our galaxy’s most abundant type of planet could be rich in liquid water due to formative interactions between ...

When evaluating possible planets out of the thousands out there, explained Prof. Bean, scientists look for liquid water as a ...

A distant gas giant the size of 10 Jupiters is now the first planet outside Earth's solar system to be mapped in three ...

Researchers have developed a new technology that can shape the spectrum of light emitted from a laser frequency comb across ...

The Habitable Worlds Observatory (HWO) is slated to be the next Great Observatory for the world. Its main focus has been ...

What can a 3D map of an exoplanet’s atmosphere teach astronomers about the planet’s formation, evolution, and composition?

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

Astronomers have created the first three-dimensional (3D) map of a planet orbiting another star, revealing an atmosphere with distinct temperature zones – one so scorching that it breaks down water ...

Newly discovered multi-wavelength view of a stellar eruption on a young Sun-like star is changing how we think about life's ...
