Frost happens throughout the Solar System, creating beautiful views. Learn why and check out the latest in space news.
NASA’s James Webb Space Telescope (JWST) will soon give us valuable data on the dozens of distant objects found beyond the orbit of Neptune in a region known as the Kuiper belt.
Pluto, everyone’s favorite former planet, takes center stage in this week’s Downlink.
With space missions like JWST and Voyager, decades of development yield decades of discovery.

A collection of before and after slider images showing how views of planets in our solar system have changed over the years since NASA was created.
The Planetary Society has always enjoyed the connections between science and art, so when I saw Leila Qışın's sketches pop up on her Twitter feed during the recent New Horizons team meeting, I knew I had to share them with you.
In a new preprint, Mike Brown and Bryan Butler show evidence that two Kuiper belt moons are even bigger than we used to think. They are Eris' moon Dysnomia, and Orcus' moon Vanth.
Google Maps released several new map products that allow you to see the locations of named features on many solar system planets and non-planets, spinning them around in space with your mouse.
Last week's Division for Planetary Sciences/European Planetary Science Congress meeting was chock-full of science from New Horizons at Pluto.
One year after the New Horizons Pluto flyby, Emily reflects on its significance.
On July 6 at Lowell Observatory in Flagstaff, Arizona, the science team convened at the place where Pluto was discovered. Ted Stryk reports from the meeting.

What types of aerosols do we find in the atmospheres around the Solar System, and why does what we call them—clouds vs. haze vs. dust—matter? Sarah Hörst explains.
Pluto is reluctant to give up its secrets. Last week at the American Geophysical Union meeting I attended sessions featuring results from the New Horizons mission, and most of the presentations could be summed up thusly: the data sets are terrific, but there are still a lot of Pluto features that have scientists scratching their heads.
I have a newly updated scale comparison graphic to share: all the round worlds in the solar system smaller than 10,000 kilometers in diameter, now with added Pluto, Charon, and Ceres.
Last week, the pile of New Horizons LORRI camera raw image releases included nine frames from a high-resolution mosaic on Charon. Together with the color MVIC view, they make a 3D global photo of Pluto's moon. Other recently released goodies include a global backlit color image of Pluto and the first image that resolves the tiny moon Styx.
Now that New Horizons is regularly sending back data, the mission is settling into a routine of releasing a set of captioned images on Thursdays, followed by raw LORRI images on Friday. The Thursday releases give us the opportunity to see lovely color data from the spacecraft's Ralph MVIC instrument. This week, the newly available color data set covered Charon.

Today, New Horizons released a stunning new image of Pluto's backlit mountains and hazes. I explain how the image was taken with its Ralph Multispectral Visible Imaging Camera.
