“All planets in the Milky Way may be formed by the same building blocks, meaning that planets with the same amount of water and carbon as Earth,” says Professor Anders Johansen.

Artist’s impression of the protoplanetary disk with magnetic field lines. Credit: Jean Favre CSCS In the last 25 years, scientists have discovered over 4000 planets beyond the borders of our solar system. From relatively small rock and water worlds to blisteringly hot gas giants, the planets display a remarkable variety. […]

An SwRI scientist used a new model to estimate Mars’ bombardment history. This new model indicated that some of the most prominent terrains associated with ancient water activity may be hundreds of millions of years older than previously thought, important data as NASA’s Perseverance rover prepares to land in one […]

Remnants of planetary crust disintegrating under the tidal forces around a cool white dwarf. Material in the disc becomes vapourised close to the central star and flows onto the white dwarf atmosphere.

Weathering of sedimentary rock at Gale Crater likely happened under Iceland-like temperatures more than 3 billion years ago, when water still flowed on Mars. Rice University researchers compared data collected by the Curiosity rover, correlated with conditions at various places on Earth, to make their determination. Credit: NASA Once upon […]

An artist’s conception shows a protoplanetary disk of dust and gas around a young star. New research by Rice University shows that Earth’s nitrogen came from both inner and outer regions of the disk that formed our solar system, contrary to earlier theory.

The TRAPPIST-1 system has long be studied by exoplanet hunters due to its unique quantity of planets that happen to also be Earth sized. In a recent paper, a team of scientists led by Erik Agol at the University of Washington, dove into more detail on the density of the seven known planets in […]

NASA has authorized a mission extension for its Juno spacecraft […]
