Pluto pulled Adeene Denton into its orbit during her undergraduate internship at the Lunar and Planetary Institute in Houston. It was summer 2015, when the New Horizons spacecraft zoomed past the ...

Many of the most interesting bodies in our Solar System aren’t planets, but the moons that orbit them. They have active volcanoes, hydrocarbon oceans, geysers, and moon-wide oceans buried under icy ...

The NASA/ESA/CSA James Webb Space Telescope has provided the first direct measurements of the chemical and physical properties of a potential moon-forming disk encircling a large exoplanet. The carbon ...

The moon is our constant companion and the only natural object that always orbits Earth. It's about four times smaller than Earth and its gravity is much weaker, which is why astronauts bounce around ...

"In our solar system, the most massive moon is Ganymede, which is still extremely small compared to what we are inferring here." When you purchase through links on our site, we may earn an affiliate ...

A model based on numerical simulations reveals why Jupiter has a larger number of larger moons than Saturn. The model, developed by a team of astronomers from Japan and China, has also uncovered how ...

Artist’s impression of the simulations conducted in this research. Jupiter (lower left) has a strong magnetic field which creates a cavity in its circumplanetary disk. Saturn (upper right) lacks a ...
