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

The People Have Voted on 2007 OR10's Future Name!

Gonggong is the fan favorite name for this icy distant world, but the International Astronomical Union's (IAU) Committee for Small-Body Nomenclature has the final say.

2007 OR10 Needs a Name!

It’s time to give 2007 OR10 a name. We’re asking for your help to pick a suitable name for the largest as-yet-unnamed solar system world to submit to the International Astronomical Union (IAU).

Some big moons in the Kuiper belt

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.

Planetary Society-funded telescopes help find ring around Haumea, a distant dwarf planet

Haumea has a ring! Two telescopes used in the discovery—one in Slovenia, and one in Italy—received funding from The Planetary Society's Shoemaker Near Earth Object (NEO) Grant program, which helps amateur astronomers find, track and characterize near-Earth asteroids.

DPS/EPSC update on New Horizons at the Pluto system and beyond

Last week's Division for Planetary Sciences/European Planetary Science Congress meeting was chock-full of science from New Horizons at Pluto.

DPS/EPSC update: 2007 OR10 has a moon!

The third-largest object known beyond Neptune, 2007 OR10, has a moon. The discovery was reported in a poster by Gábor Marton, Csaba Kiss, and Thomas Mueller at the joint meeting of the European Planetary Science Congress and the Division for Planetary Sciences of the American Astronomical Society (DPS/EPSC) on Monday.

Rapidly Rotating Regular Satellites and Tides

Pluto’s small moons have unusual rotation rates and states. Now we know a moon of another dwarf planet does as well. Is there a connection?

A Moon for Makemake

The solar system beyond Neptune is full of worlds hosting moons. Now we know that the dwarf planet Makemake has one of its very own.

"Planet Nine" update: Possible resonances beyond the Kuiper belt?

A new paper by Renu Malhotra proposes that an undiscovered distant planet could have organized extremely distant Kuiper belt objects into orbital resonances.

Pluto updates from AGU and DPS: Pretty pictures from a confusing world

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.

The round worlds in the solar system: An updated graphic

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.

Charon in 3D

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.

New Horizons releases new color pictures of Charon, high-resolution lookback photo of Pluto

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.

Lose yourself in this high-resolution portrait of Pluto

Enlarge this image to its full 8000-pixel-square glory and lose yourself in it.

Spectacular New Horizons photo of Pluto's hazes and mountains: How it was made

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.

Pretty Pictures: Downlink of the Full New Horizons Data Set Has Begun

New Horizons has begun the long process of downlinking all the images it acquired during its July Pluto flyby.

Three space fan visualizations of New Horizons' Pluto-Charon flyby

It has been a difficult wait for new New Horizons images, but the wait is almost over; Alan Stern announced at today's Outer Planets Advisory Group meeting that image downlink will resume September 5. In the meantime, a few space fans are making the most of the small amount of data that has been returned to date.

Looking back at Pluto

I don't think anyone was prepared for the beauty -- or the instant scientific discoveries -- in this
