NASA Captures Impossible Glimpse of Kuiper Belt Object Billions of Miles Away

In about a year and a half from now, the New Horizons Spacecraft will whizz past a distant Kuiper Belt object named 2014 MU69. This rocky relic of the ancient Solar System—which is located about four billion miles away—just passed in front of a distant star, resulting in one of the more extraordinary eclipses ever captured by scientists.

There’s Growing Evidence That Pluto’s Largest Moon Had a Massive Ocean

Pluto’s moon Charon is the best sidekick a dwarf planet could hope for: unwavering in its loyalty, content to be a minor character in somebody else’s narrative. But two years after the New Horizons flyby, the largest of Pluto’s five moons is finally getting some well-deserved time in the spotlight. New research suggests that Charon’s storied history includes tectonic activity, cryovolcanism, and perhaps, a globe-spanning ocean. Read More >>

Fly Over Pluto in this Incredibly Detailed New NASA Video

Pluto is the unquestionably the most goth (dwarf) planet in the solar system. Its cold, icy heart and underworld-themed moons are absolutely spooktacular, and yet none of us will ever get to see them in person. Thankfully, new video from NASA gives us an up close and personal tour of our favourite (former) planet. It’s almost as metal as the real deal. Read More >>

Scientists Are Already Planning the Next Mission to Pluto

The Pluto-shaped void in our hearts has yet to be filled by Planet 9, copious amounts of Ben & Jerry’s, or anything. Ever since the summer of 2015, when NASA’s New Horizons performed a six-month-long reconnaissance flyby study of Pluto and its moons, fans of the dwarf planet have wondered if or when we’d ever go back. According to New Horizons principal investigator Alan Stern, he and some other planetary scientists are already drawing up the blueprint for a return trip—and this time, it’d be much more than just a flyby.

NASA Scientists Have a Plan to Make Pluto a Planet Again

“It’s bullshit,” Alan Stern, principle investigator of NASA’s New Horizons mission to Pluto, has said about the demotion of Pluto from the ranks of official planet status. Now Stern is heading up a team of NASA scientists who have proposed a new definition of planets that would do more than just reinstate the icy dwarf planet with the big heart to its former glory.

New Horizons Spacecraft is Approaching a Mysterious Red Object

NASA’s New Horizons space probe is currently speeding towards a mysterious Kuiper Belt Object known as MU69. Recent observations of the distant object indicate a very reddish surface—possibly even redder than the splotches found on Pluto. Read More >>

Pluto’s Liquid Water Ocean Might Be Insanely Deep

In recent months, there’s been growing evidence that Pluto is hiding a liquid water ocean beneath its frozen surface. New models by researchers at Brown University support this hypothesis, and take it one mind-boggling step further: Pluto’s ocean may be more than 100 kilometres (62 miles) deep. Read More >>

We Finally Know What Made the Huge Heart on Pluto

Almost as soon as Pluto came into view, we saw it: a big heart splashed across half the dwarf planet’s surface, like something left it there on purpose for us to see. A year after we spotted it, we have an answer as to what put it there. Read More >>

Pluto Is Emitting X-Rays, and That’s Really Weird

Something very strange is going on around Pluto. The icy world that sits some 3.6 billion miles from the sun appears to be emitting x-rays—high energy radiation associated with gases with temperatures of a million degrees. That makes Pluto the furthest known x-ray source in our solar system. If confirmed, the finding could reshape our understanding of the dwarf planet’s atmosphere. Read More >>
