The potential habitability of known exoplanets is often categorized by a nominal equilibrium temperature assuming a Bond albedo of either 0.3, similar to Earth, or 0.

We present significant differences in the simulated atmospheric flow for warm, tidally-locked small Neptunes and super Earths (based on a nominal GJ 1214b) when solving the simplified, and commonly used, primitive dynamical equations or the full Navier-Stokes equations.

Astronomers have gleaned some of the best data yet on the composition of a planet known as HR 8799c -- a young giant gas planet about 7 times the mass of Jupiter that orbits its star every 200 years.

Earth's water may have originated from both asteroidal material and gas left over from the formation of the Sun, according to new research. The new finding could give scientists important insights about the development of other planets and their potential to support life.

Resonating oscillations of a planet's atmosphere caused by gravitational tides and heating from its star could prevent a planet's rotation from steadily slowing over time, according to new research by Caleb Scharf, who is the Director of Astrobiology at Columbia University.

We have investigated the thorium (Th) abundance in a sample of 53 thin disc solar twins covering a wide range of ages.

The Earth is more than a one Earth-mass, one Earth-radius, one Earth-density planet. It is the only known terrestrial planet to undergo plate tectonics, have continental crust and a strong geodynamo.

The word "HAZMAT" describes substances that pose a risk to the environment, or even to life itself. Imagine the term being applied to entire planets, where violent flares from the host star may make entire worlds uninhabitable by affecting their atmospheres.

An international team of scientists, including high performance computing (HPC) experts from the King Abdullah University for Science and Technology (KAUST), astronomers from the Paris Observatory and the National Astronomical Observatory of Japan (NAOJ), in collaboration with NVIDIA, is taking the search for habitable planets and observation of first epoch galaxies to the next level.

Planetary rotation rate has a significant effect on atmospheric circulation, where the strength of the Coriolis effect in part determines the efficiency of latitudinal heat transport, altering cloud distributions, surface temperatures, and precipitation patterns.
