Stories, updates, insights, and original analysis from The Planetary Society.
How did our solar system come to be? Why are the planets, asteroids, comets, and other small worlds where they are now?
Take a look at space image processing, and try it yourself. Plus, catch up on the week’s space news.
There's still time to get outside and see Jupiter and Saturn together in the evening sky.
With 3 spacecraft en route to Mars, we’re sharing mission news, Martian maps, and a chance to meet Bill Nye.
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.
Last month marked the 40th anniversary of the historic Voyager 1 encounter with Jupiter in 1979.
A collection of before and after slider images showing how views of planets in our solar system have changed over the years since NASA was created.
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.
On March 29, vigilant astronomer Maciel Bassani Sparrenberger discovered that a new bright spot had broken out in Saturn's high northern latitudes.
SpaceX's Falcon Heavy is not just for big payloads, it can also throw light things into space very fast. And that has significant implications for the exploration of distant destinations in our outer solar system—particularly the ocean moons of the giant planets.
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.
Björn Jónsson argues that even now, 40 years after Voyager 1 and 2 were launched, a lot of the data they returned is still of high interest.
Amateur image processor Ian Regan shares a stunning mosaic of Saturn in all its ringed glory.
An unusual photo of Saturn by astrophotographer Damian Peach shows the planet and its largest moon nestled among the star-filled lane of the Milky Way.
Cheers erupted in the Von Karman auditorium at the Jet Propulsion Laboratory early Thursday morning as a squiggly green line on a graph developed a crisp, tall peak, signifying that the Cassini spacecraft was calling home after surviving its first plunge between Saturn and its ring system.
NASA's long-lived Cassini spacecraft is about to buzz Titan for the final time, putting it on course for a spectacular mission finale that concludes in September.
NASA's Cassini spacecraft sniffed out molecular hydrogen spewing from Enceladus' subsurface ocean. The discovery means Saturn's moon has all the basic ingredients needed to support life.
