(News from JHUAPL) For the first time, a spacecraft has sent back pictures of the sky from so far away that some stars appear to be in different positions than we see from Earth. More than four billion miles from home and speeding toward interstellar space, NASA’s New Horizons has traveled so far that it…

Why Are Pluto’s Moons So Weird?
(Updated post from 2016) Whether you call it a planet, a dwarf planet, or a Kuiper Belt or Trans-Neptunian Object—or all of the above—there’s no denying that Pluto and its family of moons are true curiosities in the Solar System. Not only does little Pluto have one moon, Charon, that’s so massive in comparison that they…
Three Years Ago Today New Horizons Passed Pluto
Holy Hadean history Batman, where does the time go? Today marks the third anniversary of New Horizons‘ flyby of Pluto and Charon, the first, last, and as yet only mission ever to the distant dwarf planet (aka the reigning King of the Kuiper Belt.) All of the close-up detailed images of Pluto and Charon we…
New Horizons Fine-Tunes Its Course for MU69
A little goes a long way—especially when you’re traveling 51,000 mph! On Feb. 1, 2017 NASA’s New Horizons spacecraft performed a 44-second thruster burn that adjusted its course by just under 1 mph toward its next target, the Kuiper Belt object 2014 MU69. “One mile per hour may not sound like much,” said mission Principal…
Here’s What It Would Look Like to Land on Pluto’s Heart
What would it look like to approach Pluto for a landing? Perhaps some day in the future a robotic mission will do exactly that and we’ll know for sure, but for now we have to use our imaginations…luckily we do have some incredible images of Pluto to help with the details, thanks to NASA’s New…
Behold the Most Distant Crescent Moon
At first glance this pixelated picture may not look all that spectacular, but it gains a whole new meaning when you realize what it’s actually showing: a look at the most distant crescent moon ever seen! But this isn’t Earth’s moon; it’s Charon, Pluto’s largest companion, lit by the light from a Sun 3.2 billion miles away—some…
Pluto Has Giant Versions of Ice Formations Found on Earth
Using a model similar to what meteorologists use to forecast weather and a computer simulation of the physics of evaporating ices, scientists have found evidence of snow and ice features on Pluto that, until now, had only been seen on Earth.

Icy Nix Indicates Pluto’s Moons Are Leftovers From a KBO Collision
Recent findings from the New Horizons team reveal that Pluto’s third-largest satellite Nix is covered in the purest water ice yet observed in the dwarf planet system, even purer in spectra than what was seen on its slightly larger sibling Hydra. This analysis further supports the hypothesis that Pluto’s moons were created in an impact event…
Hail Hydra: Pluto’s Moon is Covered in Almost Pure Water Ice
Discovered in June 2005, distant Pluto’s outermost moon Hydra it thought to have formed during the same collision four billion years ago that created the Pluto-Charon system that we see today. Yet despite its age this 31-mile (50-km) -long moon appears remarkably clean and bright, as witnessed by New Horizons during its close pass through the Pluto system in July 2015.
Pluto’s Frozen Lake Hints at a Warmer Past
Hockey fans take note: future visitors to Pluto may want to bring along their sticks and skates—the distant planet may harbor some pristine ice in the form of frozen ponds and lakes! (NASA might have to work on a lightweight, collapsible Zamboni first though.)
Surprise! Pluto May have Clouds
We could be calling it Cloudgate—”leaked” information from internal emails identifying structures in Pluto’s already hazy atmosphere that could very well be clouds, based on a March 4 article in New Scientist. The image above shows sections of a New Horizons image attached to an email sent by SwRI scientist John Spencer, in which he noted particularly…
