Gravity Controls Enigmatic Moon's Geysers

These images from NASA’s Cassini spacecraft show how the pull of the planet affects the amount of material ejected by geysers on Saturn’s moon Enceladus. It turns out that the moon launches more spray when it is farther away from Saturn. Image Credit: NASA/JPL-Caltech/University of Arizona/Cornell/SSI

Saturn’s 314-mile-wide icy moon Enceladus has been […]

Meteors flashing across the sky are a common sight here on Earth, but of course they are not limited to only our planet; these bits of rocky debris, smaller pieces of asteroids and comets known as meteoroids, can be found […]

NASA's Hubble Reveals Rogue Planetary Orbit for Fomalhaut B

This false-color composite image, taken with the Hubble Space Telescope, reveals the orbital motion of the planet Fomalhaut b. Based on these observations, astronomers calculated that the planet is in a 2,000-year-long, highly elliptical orbit. The planet will appear to cross a vast belt of debris around the star roughly 20 years from […]
