Stories, updates, insights, and original analysis from The Planetary Society.
Looking at planets and moons from near and far, and figuring out how to get all the way out there.
When we look at our planet, look for life, or direct a rover to look at itself, we see ourselves in new ways.
Here are some of our favorite pictures of Saturn's iconic rings, featuring images from Cassini, Voyager 1 and 2 and more.
Six scientists share the major planetary science discoveries of the past decade, and the questions that will drive the next 10 years of solar system exploration.
The leader of the Cassini spacecraft imaging team discusses pale blue dots, life on Enceladus, terraforming Mars, Pluto, Carl Sagan, and more.
Long before the Cassini-Hugygens spacecraft launched in 1997 to explore Saturn and Titan, The Planetary Society urged NASA to make the mission a reality.
Ian Regan, producer of the Titan segment of In Saturn's Rings, describes the meticulous process of creating the stunning visuals of this shrouded moon.
One of the Cassini mission's goals was to figure out how long a day on Saturn is. We still don't know. A new paper reports a measurement of the rotation period of Saturn that is different from past measurements.
The Juno spacecraft that is currently orbiting Jupiter has obtained the first good images of Jupiter's polar regions. I am presenting here a combined global map of Jupiter, made from a Cassini map I made for the equatorial and temperate regions and polar maps made from the Juno JunoCam and JIRAM polar images.
Happy Monday! Here's a picture of Prometheus. You may think it's a picture of Saturn. Look hard, toward the bottom, and you'll see Prometheus, doing its part to keep the F ring in line.
On this Moon Monday, I'm featuring an animation processed by Gordan Ugarkovic, showing Jupiter's volcanic moon Io with its prominent plumes.
Emily's first report from the Lunar and Planetary Science Conference is on the solar system's most atmospheriffic satellite, Saturn's moon Titan.
Amateur image processor Ian Regan shares the story of processing Cassini's final images of the ringed planet.
The Fall 2017 issue of The Planetary Report is in the mail and available online now to our members!
Cassini is no more. At 10:31 according to its own clock, its thrusters could no longer hold its radio antenna pointed at Earth, and it turned away. A minute later, it vaporized in Saturn’s atmosphere. Its atoms are part of Saturn now.
A timeline of what to expect from the great mission during its final hours.
The end of the Cassini mission is a harbinger for a looming gap in outer planets exploration missions.
Sadly, the Cassini mission ends soon. We're halfway through the
Emily shares another of her popular size comparisons of solar system bodies, taking advantage of Cassini's recent views of Saturn's tiniest moons.
