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?
Look back on the year’s accomplishments and enjoy the beauty of the cosmos.
Feast your eyes on these images from space, catch up on the latest in exploration news, and get the lowdown on what’s up in the night sky.
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 mission includes a flyby of Neptune and measurements of the heliosphere, the electrically charged gas bubble surrounding our solar system
Mark Marley explains what planetary scientists mean when they say the word
Imagine 2 icy worlds far from the Sun. Their serene, blue atmospheres. Huge, ominous-looking storms. Tantalizing glimpses of moons with exotic, icy terrains. Delicate sets of encircling rings.
The color of Uranus and Neptune is similar, but not identical. Uranus appears greener and Neptune bluer.
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.
One fact dominates the planning for any mission to Uranus or Neptune: They lie far from the sun. A newly released NASA report looks at how we can explore these icy giants.
Only one spacecraft has ever visited Uranus and Neptune: Voyager 2, in the late 1980s. A new NASA report explores the reasons to go back, and what type of mission might take us there.
Beautiful new amateur work with 27-year-old Voyager data.
When are the solstices and equinoxes on the giant planets, and when are they best positioned for view from Earth? I ask these questions a lot as I write about Earth photos of giant planets, and I finally decided to gather the answers to those questions in a single post.
Image processing enthusiast Ian Regan is working on a cool new version of the Voyager 2 Neptune approach movie.
There are no spacecraft at Uranus or Neptune, and there haven't been for 30 and 25 years, respectively. So we depend on Earth-based astronomers to monitor them, including Damian Peach.
More examples of imperfect--but tantalizing--images from deep space.
In honor of the 25th anniversary of the Voyager 2 flyby of Neptune, image magician Björn Jónsson has produced two new global mosaics of the distant ice giant, the highest-resolution ever made.
The Voyager mission may be the ultimate expression of our desire to explore, but why does that will exist in the first place? Why is it unique to humans?
Can features on Neptune be observed by amateur astronomers? For years, the Hubble Space Telescope and some professional terrestrial observatories have been revealing incomplete belts and spots on the surface of Neptune. Now, spots have been imaged by amateurs.
With the recent announcement by NASA that the 36 year-old spacecraft Voyager 1 has officially entered interstellar space at a distance from the sun about four times further than Neptune's orbit, and with Voyager 2 not far behind, it seems worthwhile to explore how humans managed to fling objects so far into space.
