Here are the distinct ways in which the moons of our Solar System formed.
The mission proposal calls for nuclear fission power. Breakthroughs would boost China’s overall exploration capabilities.
Intriguing moons that may hide water beneath their surfaces, and what it takes to visit them.
Ocean worlds are among the best candidates to search for life.
Neptune and Triton come into focus as destinations worth exploring.
Is it time NASA sent an orbiter to study the other blue planet in our solar system? Proposals for missions to study the ice giant planet Neptune and its mysterious moon Triton have been on NASA’s to-do list for over a decade, but until now nothing has happened.
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.
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.
Two months. Eight and half weeks. 58 days. It's a concept almost too difficult to grasp: we are on Pluto's doorstep.
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.
The European Space Agency will announce two major science missions this November, one of which is likely to be devoted to solar system exploration.
A few presentation slides with pretty pictures, sized to scale, of the large moons of the solar system.
On a lonely evening, what is one to do but to dip into archival space image data and surface with a gorgeous photo of a crescent Neptune and Triton?
Ted Stryk reminisces on how he was turned on to astronomy.
I'm preparing a talk for the Pacific Astronomy and Telescope Show here in Pasadena on Sunday afternoon at 1:45. I have spent the morning putting together a slide that I have long wanted to have for presentations.
The second day of the New Horizons Workshop on Icy Surface Processes was about geology and geophysics. This long post just covers the first talk of that day.
