Astronomers on Monday made a “big” announcement about exoplanets, and it is big—literally. Another new world has been discovered, which is quite routine now these days, but this one is different, and unexpected: a planet which is more than […]

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 […]

Hubble Space Telescope Discovers New Moon Orbiting Neptune

This composite image from the Hubble Space Telescope shows the location of Neptune’s newest known moon, S/2004 N 1, which was discovered by Mark Showalter of the SETI Institute. The black and white portion and the color inset were both taken in 2009. Image Credit: NASA, ESA, and M. Showalter (SETI Institute).

The Cassini spacecraft peers through Titan’s thick clouds to spy on the region dubbed “Senkyo” by scientists. The dark features include vast fields of dunes, composed of solid hydrocarbon particles precipitated out of Titan’s atmosphere. And Titan’s southern pole is shrouded in the recently formed polar vortex.
