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.
The Voyager missions transformed most of the large worlds of the solar system from points of light into places to be explored.
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.
Today's press briefing at the Applied Physics Laboratory in California was preceded by hours of New Horizons team members cryptically dropping hints on Twitter at astonishing details in the seven images downlinked since the flyby. The images are, in fact, astonishing, as well as beautiful, surprising, and puzzling.
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.
Two months. Eight and half weeks. 58 days. It's a concept almost too difficult to grasp: we are on Pluto's doorstep.
In pictures of the planets, the stars aren't usually visible. But when they do appear, they're spectacular.
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.
New Horizons team member Simon Porter reports on the state of the mission and Pluto system science from the recent science team meeting at the Applied Physics Laboratory.
