Jupiter dazzles and Neptune beckons

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.

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.

China Considers Voyager-like Mission to Interstellar Space

The mission includes a flyby of Neptune and measurements of the heliosphere, the electrically charged gas bubble surrounding our solar system

Not a Heart of Ice

Mark Marley explains what planetary scientists mean when they say the word

The Realm of the Ice Giants

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 subtle color difference between Uranus and Neptune

The color of Uranus and Neptune is similar, but not identical. Uranus appears greener and Neptune bluer.

Voyager 40th anniversary: Revisiting the Voyagers' planetary views

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.

How we would explore Uranus or Neptune

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.

Revisiting the ice giants: NASA study considers Uranus and Neptune missions

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.

Some beautiful new (old) views of Neptune and Triton

Beautiful new amateur work with 27-year-old Voyager data.

Oppositions, conjunctions, seasons, and ring plane crossings of the giant planets

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.

Approaching Neptune

Image processing enthusiast Ian Regan is working on a cool new version of the Voyager 2 Neptune approach movie.

Checking in on Uranus and Neptune, September 2015 edition

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.

Flawed Beauties

More examples of imperfect--but tantalizing--images from deep space.

Best-ever Neptune mosaics for the 25th anniversary of Voyager 2's flyby

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.

Cosmos with Cosmos Episode 6: Travellers' Tales

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?

Neptune: The new amateur boundary?

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.

Gravity assist

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.

Europe Will Select Its Next Major Science Mission in November

The European Space Agency will announce two major science missions this November, one of which is likely to be devoted to solar system exploration.

Lesser-known views of Uranus and Neptune

Despite the fact that Voyager 2 returned relatively few high-resolution images from either Uranus or Neptune, there are many more photos in the archives than regularly make it to public view.
