By Jove! (Literally)
Jupiter’s moons have always been exciting to explore, and a new era of Jovian moon research is about to begin.
Your guide to rings of the Solar System
Tour the rings of Jupiter, Saturn, Uranus, and Neptune, plus asteroids, a dwarf planet, and an exoplanet.
Mind-blowing space volcanoes
Taking a look at volcanic worlds in our solar system and exoplanets that might crack under pressure.
The Next 10 Years
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.
A new look at Europa, with old data
Ted Stryk shows us a new color, near-global view of Europa made from Galileo spacecraft data captured in 1996.
Space grade electronics: How NASA’s Juno survives near Jupiter
Take a look at how electronics of spacecraft are built to survive the harshness of space environments.
Jupiter's Great Red Spot
On the 20th anniversary of Galileo's orbit insertion around Jupiter, amateur image processor Björn Jónsson shares some of the mission's first images of Jupiter's iconic massive storm.
Galileo's best pictures of Jupiter's ringmoons
People often ask me to produce one of my scale-comparison montages featuring the small moons of the outer solar system. I'd love to do that, but Galileo's best images of Jupiter's ringmoons lack detail compared to Cassini's images from Saturn.
New Robotic Spacecraft Posters
Another round of posters to celebrate historic planetary missions.
Now that I have a reasonable-resolution global color view of Pluto, I can drop it into one of my trademark scale image montages, to show you how it fits in with the rest of the similar-sized worlds in the solar system: the major moons and the biggest asteroids.
Several global maps have been made of Europa, but amateur image processor Björn Jónsson felt they could be improved—so he decided to make a new one.
More examples of imperfect--but tantalizing--images from deep space.
LPSC 2014: Plate tectonics on another world: Europa
Simon Kattenhorn and Louise Prockter may finally have found subduction zones on Europa, which would it the only other place in the solar system besides Earth that is known to have active plate tectonics.
Through a Glass, Darkly
When sent from deep space, even imperfect images can inform and amaze.
It's time to reassess Europa exploration, past, present and future. The Destination Europa! session at AGU, inspired by the eponymous website and movement, didn't take exactly that message as its theme, but it's what I got from the presentations. What an ELECTRIFYING meeting this has been for Europa exploration!
A serendipitous observation of tiny rocks in Jupiter's orbit by Galileo
A look at an older paper describing Galileo's possible sighting of individual ring particles orbiting Jupiter as companions to its inner moon Amalthea.
Galileo's images of Gaspra
Last week I trawled the archives to find all of Galileo's images of asteroid Ida; this week, I turned to Gaspra.
Galileo got so many more images of Ida than I realized
While writing up the cruise-phase issues of the Galileo Messenger a couple of weeks ago, I came across a fuzzy montage of images of Ida that I had not seen before. So I decided to spend some time digging into the Planetary Data System to see if there were more images to be found. I found lots and lots pictures that I'd never seen before!
Galileo Messengers: Cruise to Venus, Earth, Gaspra, Earth, Ida, and almost to Jupiter
It's taken me a year to face the emotionally draining task of reading and writing about Galileo's cruise phase as chronicled in the mission's newsletters.
My ever-popular asteroids-and-comets montage, now in color, with bonus Toutatis
My collage of all the asteroids and comets visited by spacecraft is probably the single most popular image I have ever posted on this blog. I've now updated it to be in color and to include Toutatis.
