New comprehensive mapping of the radiation pummeling Jupiter’s icy moon Europa reveals where scientists should look — and how deep they’ll have to go —…
Auroras appear on Earth as ghostly displays of colorful light in the night sky, usually near the poles. Our rocky neighbor Mars has auroras too,…
Life as we know it needs water to thrive. Even so, we see life persist in the driest environments on Earth. But how dry is…
The discovery of a dark ribbon of weak hydrogen ion emissions that encircles Jupiter has overturned previous thinking about the giant planet’s magnetic equator. An…
This image captures a high-altitude cloud formation surrounded by swirling patterns in the atmosphere of Jupiter’s North North Temperate Belt region. The North North Temperate…
Side-by-side movies shows how dust has enveloped the Red Planet, courtesy of the Mars Color Imager (MARCI) camera onboard NASA’s Mars Reconnaissance Orbiter (MRO). The…
Chandra data indicates that a young star, known as RW Aur A, has likely destroyed and consumed an infant planet. If confirmed, this would be…
These six infrared images of Saturn’s moon Titan represent some of the clearest, most seamless-looking global views of the icy moon’s surface produced so far….
Twelve new moons orbiting Jupiter have been found—11 “normal” outer moons, and one that they’re calling an “oddball.” This brings Jupiter’s total number of known…
ESO’s Very Large Telescope (VLT) has achieved first light with a new adaptive optics mode called laser tomography — and has captured remarkably sharp test…
Pasadena Conference to Include New Insight into Dwarf Planet Ceres As NASA’s Dawn spacecraft prepares to wrap up its groundbreaking 11-year mission, which has included…
Data collected by NASA’s Juno spacecraft using its Jovian InfraRed Auroral Mapper (JIRAM) instrument point to a new heat source close to the south pole…
This image from NASA’s Mars Reconnaissance Orbiter, acquired May 13, 2018, during winter at the South Pole of Mars, shows a carbon dioxide ice cap…
In April 2018, NASA launched the Transiting Exoplanet Survey Satellite (TESS). Its main goal is to locate Earth-sized planets and larger “super-Earths” orbiting nearby stars…
Last autumn, the world was excited by the discovery of an exoplanet called Ross 128 b, which is just 11 light years away from Earth….
New research from NASA’s Cassini spacecraft’s up-close Grand Finale orbits shows a surprisingly powerful and dynamic interaction of plasma waves moving from Saturn to its…
One of the most actively changing areas on Mars are the steep edges of the North Polar layered deposits. This image from NASA’s Mars Reconnaissance…
