Much of the data returned by New Horizons has revealed Pluto to have an incredibly complex geology, with ice mountains and massive canyons. New information, via New Scientist, suggests the planet’s strange atmosphere is just as weird and mysterious. Also, it could have clouds.
The report, which includes a few new images, apparently reveals a discussion between researchers contemplating the possibility of clouds above Pluto. We already knew the planet had a surprisingly complex atmosphere, with layers of haze and the whole nine yards. Never did we expect there to be individual clouds.
“There’s a few fairly localized low-altitude features just above the limb that I’ve drawn lame arrows pointing to, but also a few bright cloud-like things that seem to be above and cutting across the topography in the circled area,” wrote Will Grundy, of the Lowell Observatory, in an email to a colleague.
You can see the image Grundy is referring to above. The clouds are faint but they do appear to be there. Obviously, it’s difficult to get the weather report from across the solar system, but it does look like clouds formed when the images were taken last year.
Researchers haven’t publicly confirmed the existence of clouds on Pluto, which could mean they aren’t entirely sure if what they’re seeing is legit. For that matter, scientists aren’t even sure what these clouds are made of if they are indeed clouds.
New Horizons still has a ton of information to beam back to Earth, so there’s a possibility we can get a definitive answer later this year. For now, just admire the images above and catch up on some of the other Pluto breakthroughs in the posts below.
NASA on Wednesday released the first high resolution close-up image of Pluto, revealing a small region of massive icy mountains. It is, in a word, stunning. And it’s getting a lot of interesting reactions from the scientific community, not only about Pluto itself, but how we think about icy worlds in our solar system. Now that NASA’s […]
NASA’s New Horizons spacecraft continues to amaze with a handful of new photos that provide us with an incredibly detailed look at Pluto’s “snakeskin” surface. The spacecraft made its closest approach to the dwarf planet all the way back on July 14, but it’s still slowly sending back heaps of information, and will continue to do so […]
NASA on Thursday revealed another amazing Pluto factoid: the planet appears to have floating hills, or icebergs. The agency said the icebergs are floating in a vast sea of frozen nitrogen at Sputnik Planum, which rests within the planet’s “heart.” “The hills are likely fragments of the rugged uplands that have broken away and are […]
NASA has released a stunning new image of Pluto’s crescent, further revealing the beauty of the beast we saw in the panorama in September. What the image lacks in finer details more than makes up for in splendor, presenting a terrific look at the lonely planet as the sun gently kisses its icy surface. Go home, New […]
Just 15 minutes after its closest approach to Pluto in July, NASA’s New Horizons captured what is now the most beautiful image of the dwarf planet. And that’s saying a lot, because the courageous spacecraft has also sent back some truly spectacular pictures—my favorite is this silhouette after New Horizons successfully made its historic flyby. […]
The image above isn’t a teaser for a Ring reboot (though one is reportedly on the way). Instead, it’s an image that was shared by NASA’s New Horizons team on Friday, showing off a backlit Pluto bathing in the sun. It’s the first time we’ve ever seen the dwarf planet like this, and although it […]
