#OTD - July 14, 2015 After nearly 10yrs & over 3 billion miles, New Horizons made its closest approach to #Pluto - about 7,750 miles above the surface, making it the first-ever space mission to explore a world so far from Earth. @NASASolarSystem @JHUAPL
New Horizons mission scientists have found evidence that cryovolcanic activity – ice volcanoes – most likely created some of the unique structures on Pluto not yet seen anywhere else in the solar system. Details:…

No matter how far we are apart, #Pluto will always have our heart. ❤️ #SpaceValentines @NASASolarSystem @JHUAPL @SwRI #ValentinesDay
Seeing the "dark side" of Pluto 🌑 The@NASAA New Horizons team has captured photos of the portion of#Plutoo's landscape that wasn't directly illuminated by sunlight — what the team calls Pluto's "dark side." @NSFf@SwRII@JHUAPLL@NASASolarSystemmV
🔴LIVE: New Horizons Project Scientist Hal Weaver of@JHUAPLL covers the latest discoveries in the Kuiper Belt in a press briefing at the AAS Division for Planetary Sciences meeting.#DPS20211 📺
Nearly 5 billion miles from home, @NASA's New Horizons sees things we can't spot from Earth.👀What's the newest mission discovery? Find out during the DPS press briefing today at 11 AM EDT. #KuiperBeltt@JHUAPLL@SwRIIk
✨ Across the Expanse✨ In April 2021, @NASANewHorizons became the fifth spacecraft to reach 50AU, 50 times farther from the Sun than Earth. More discoveries in the outer reaches of the Kuiper Belt await. The adventure continues. @NASASolarSystem

Six years ago today, @NASA’s New Horizons made history with the first up-close exploration of the #Pluto system, resulting in the sharpest images & data gathered of Pluto & moon Charon as it zipped by at +30,000mph. @NASASolarSystem @JHUAPL @SwRI
New Horizons has reached a rare deep-space milepost - 50AU from the Sun. It is now 50 times farther from the Sun than Earth! New Horizons is just 1 of 5 spacecraft to reach this distance on its way out of the solar system. @JHUAPL @SwRI @NASASolarSystem
It's the 15th anniversary of the @NASA New Horizons launch!🚀 PI@AlanSternn looks back at the 5,840 days since the spacecraft left Earth, traveling ~4.5 billion miles to the Kuiper Belt, the most distant region of our planetary @JHUAPLL@SwRIIA
Traveling billions of miles beyond the inner solar system and its accompanying light pollution, New Horizons answered the question: How dark is space? � (📸: STScI/Joe Olmstead) @NOIRLabAstror@SpaceTelescopep@JHUAPLP@NASASolarSystemeSn
Here are 10 of the coolest, weirdest and most unexpected findings about the #Pluto system that scientists have learned since 2015, thanks to data from New Horizons. via @JHUAPL
Five years after New Horizons’ historic flyby, here are 10 cool things we learned About Pluto. #plutoflyby @NASA @JHUAPL @NASASolarSystem @SwRI
#Plutoflyby countdown (#1) - New Horizons Team Sees Pluto in Detail #OTD in 2015, members of the New Horizons science team at @JHUAPL react to seeing the spacecraft's last and sharpest image of #Pluto before closest approach later in the day. (📸: NASA/Bill Ingalls)#5yearssT
#Plutoflyby countdown (#2) - Pluto's Heart Pluto’s bright, mysterious “heart” rotates into view, getting ready for its close-up, in this image taken July 12. Eventually it is the target of the highest-resolution images that will be taken during the closest approach to Pluto.
#Plutoflyby countdown (#3) - Charon's Chasms & Craters Chasms, craters, & a dark north polar region are revealed in this image of Pluto's largest moon, Charon. The diagram at center shows Charon's north pole, equator & central meridian, with "possible" features labeled (r).
#Plutoflyby countdown (#4) - The Last Portrait of Pluto’s Puzzling Spots Taken early the morning of July 11, 2015, this is New Horizons' last look at Pluto's Charon-facing hemisphere revealed intriguing geologic details that were of keen interest to mission scientists.
#Plutoflyby countdown (#5) - Signs of Geology #OTD 5 years ago, New Horizons snapped this photo of Pluto from 3.3 million miles away! This image revealed tantalizing signs of geology on the side facing away from Pluto’s large companion moon, Charon.
#Plutoflyby countdown (#6) - The Dynamic Duo New Horizons was about 3.7 million miles from #Pluto and its moon Charon when it snapped this portrait late on July 8, 2015. In addition to Charon, Pluto has four other moons: Nix, Hydra, Styx, and Kerberos.
#Plutoflyby countdown (#7) - A Heart on Pluto ❤️ #OTD in 2015, mission scientists received this view of Pluto. This image was the first to be received since an anomaly on July 4 sent the spacecraft into safe mode. This pic gave us the first real good look at Pluto's heart.
Countdown to the anniversary of the #plutoflyby! Here's a look at some of the discoveries unveiled 5 years ago. #8: The Whale and the Donut🐋🍩 Scientists used this color map to decipher the markings on Pluto's surface. The long dark area (L) is “the whale.Co

More than 4 billion miles from Earth & speeding toward interstellar space, @NASANewHorizons is humankind’s farthest photographer, imaging an alien sky. Why does the spacecraft now “see” stars in a different place in the sky than on Earth? Find out: @JHUAPL

Seeing double 👀 On April 22 & 23, New Horizons will take images of two of the nearest stars, Proxima Centauri & Wolf 359. When combined w/Earth-based images, the result will be a record-setting parallax measurement. Here's how you can
#OTD in 1930, a young astronomer named Clyde Tombaugh discovered #Pluto. In so doing, he unknowingly opened the door to the vast "third zone" of the solar system we now know as the Kuiper Belt, home to countless planetesimals and dwarf planets.
Using detailed data gathered during the record-setting flyby of #Arrokoth, the New Horizons team has made a significant advance in understanding planetesimals, reshaping our understanding of how planetary bodies form in solar systems across the universe.

#OTD in 2006, New Horizons left Earth and began its unprecedented journey through the solar system! 🚀 In the last 14 years, we’ve learned so much about our own cosmic neighborhood,#Plutoo, and the#KuiperBeltt.
Unknown no longer! In a fitting tribute to the farthest flyby ever conducted by spacecraft, Kuiper Belt object #MU69 has officially been named #Arrokoth, a Native American term meaning “sky” in the Powhatan/Algonquian language. @JHUAPL @SwRI…
What's in a name? A lot, if you're a feature on #Pluto! Several people and missions who paved the way for the exploration of Pluto & the #KuiperBelt are honored in the second set of official Pluto feature names approved by @IAU_org!

The New Horizons team has published the first results from the New Year's 2019 flyby of #MU69, the most distant object ever explored by spacecraft, in @ScienceMagazine!
What makes a cool #KuiperBelt flyby movie even cooler? When the soundtrack comes from @QueenWillRock's own @DrBrianMay! 🤘
Our New Year's #KuiperBelt flyby target, #UltimaThule, is slowly revealing its secrets! Watch live TODAY at 1 pm ET as #NASANewHorizons scientists give an update at #LPSC2019.…

Close-ups from the Kuiper Belt! #NewHorizons has sent home its sharpest images from the #UltimaThule flyby, revealing new details about the farthest object ever explored by spacecraft.
#OnThisDay in 1930, Clyde Tombaugh discovered Pluto, a small planet on the outer frontier of the #solarsystem. Almost 90 years later we continue Clyde’s legacy of exploration with New Horizons which, in 2015, revealed this small world’s icy wonders.
New pics, new info! New Horizons scientists at @JHUAPL confirm the two sections (or “lobes”) of #UltimaThule are not spherical. The larger lobe more closely resembles a giant pancake and the smaller lobe is shaped like a dented walnut!……
NEW: #UltimaThule, now in higher-res! 📸 Both lobes now show many intriguing light & dark patterns of unknown origin, which may reveal clues about how it was assembled during the formation of the#solarsystemm!
