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: pluto.jhuapl.edu/News-Center/Ne…

#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. pluto.jhuapl.edu NASA Solar System Johns Hopkins APL

Searching for distant discoveries ✨🛰️ On Oct. 1, New Horizons begins its second extended mission, which includes collecting, studying and archiving unique astrophysical & scientific data - even looking for new objects to study/fly by. jhuapl.link/nh-ts3 Johns Hopkins APL Southwest Research Institute

NASA's New Horizons begins its second extended mission! 🎉 The spacecraft will continue exploring the outer reaches of the solar system, collecting particle measurements and data to better understand the Kuiper Belt and the Sun's outer heliosphere. jhuapl.link/nh-i5g

#OTD in 2019, NASA's #NewHorizons flew by Arrokoth, the farthest object ever explored by spacecraft. Arrokoth is about about 50 AU, or 4 billion miles from the Sun. New Horizons is ~56 AU from Earth and will join Voyagers 1 & 2 in interstellar space in the 2040s. Johns Hopkins APL Southwest Research Institute

#OTD in 2006, NASA's New Horizons left Earth, ultimately changing our understanding of Pluto, the Kuiper Belt, and beyond. Now, 5.2 billion miles away (and counting), New Horizons and NASA Voyager are the farthest operational human-made objects in space.

More than 17 years into its mission, NASA's #NewHorizons continues to shed light on the outer solar system. Team members shared some discoveries at the recent Lunar and Planetary Science Conference. ✨🛰️ jhuapl.link/s3s Johns Hopkins APL NASA Solar System #LPSC2023 Southwest Research Institute

It's so dark where New Horizons is – billions of miles beyond the inner solar system – that the spacecraft has the opportunity to do something that nothing else can: precisely measure the darkness of space itself. NOIRLab's Tod Lauer explains: jhuapl.link/nh-ayf

The New Horizons spacecraft is healthy, active, and speeding across the Kuiper Belt. Principal Investigator Alan Stern covers the range of observations New Horizons is making – with the spacecraft serving as an observatory in the outer solar system. jhuapl.link/nh-358

Following a senior review and feedback from a diverse set of stakeholders, NASA will continue the NASA New Horizons mission focus on multidisciplinary science. Its extended operations will continue until the spacecraft exits the Kuiper Belt, expected in 2028-2029. More:

New Year, New Horizons. As we count down to the New Year, set a resolution to be part of space exploration. Send your name to Jupiter’s moon Europa on NASA’s NASA Europa Clipper spacecraft. But hurry! The deadline to sign up is Dec. 31: go.nasa.gov/47ySnad

#OTD in 2019, NASA's New Horizons flew by Arrokoth, the farthest object ever visited by spacecraft. Arrokoth was about 43 AU, or 4 billion miles from Earth. New Horizons is currently ~58 AU from home. pluto.jhuapl.edu

New observations from NASA’s New Horizons spacecraft hint that the Kuiper Belt – the vast, distant outer zone of our solar system populated by hundreds of thousands of icy, rocky planetary building blocks – might stretch much farther out than we thought. jhuapl.link/y8v

New Horizons is healthy and speeding across the Kuiper Belt, nearing a distance of 60 times as far from the Sun as Earth is! The spacecraft continues to collect data on our Sun’s cocoon in the galaxy (the heliosphere) and transmit that data back to Earth. jhuapl.link/nh-gso

Just how dark is deep space? 🌌 Astronomers may have finally answered this long-standing question by tapping into the capabilities and distant position of NASA’s New Horizons spacecraft, by making the most precise, direct measurements ever of the total amount of light the

A new, peer-reviewed study authored by NASA’s New Horizons Kuiper Belt search team reports the detection of an unexpected population of very distant bodies in the Kuiper Belt. The discovery suggests the solar system may have formed from a much larger protostellar disk, and
