LAUREL, Md. (NASA PR) — Cross your eyes and break out the 3D glasses! NASA’s New Horizons team has created new stereo views of the Kuiper Belt object nicknamed Ultima Thule – the target of the New Horizons spacecraft’s historic New Year’s 2019 flyby, four billion miles from Earth – and the images are as cool and captivating as they are scientifically valuable.
LAUREL, Md. (NASA PR) — The mission team called it a “stretch goal” – just before closest approach, precisely pointing the cameras on NASA’s New Horizons spacecraft to snap the sharpest possible pictures of the Kuiper Belt object nicknamed Ultima Thule, its New Year’s flyby targetand the farthest object ever explored.
Now that New Horizons has sent those stored flyby images back to Earth, the team can enthusiastically confirm that its ambitious goal was met.
MARSEILLE, France (ESA PR) — Feeling stressed? You’re not alone. ESA’s Rosetta mission has revealed that geological stress arising from the shape of Comet 67P/Churyumov–Gerasimenko has been a key process in sculpting the comet’s surface and interior following its formation.
Small, icy comets with two distinct lobes seem to be commonplace in the Solar System, with one possible mode of formation a slow collision of two primordial objects in the early stages of formation some 4.5 billion years ago. A new study using data collected by Rosetta during its two years at Comet 67P/C-G has illuminated the mechanisms that contributed to shaping the comet over the following billions of years.
LAUREL, Md. (JHUAPL PR) — An evocative new image sequence from NASA’s New Horizons spacecraft offers a departing view of the Kuiper Belt object (KBO) nicknamed Ultima Thule – the target of its New Year’s 2019 flyby and the most distant world ever explored.
These aren’t the last Ultima Thule images New Horizons will send back to Earth – in fact, many more are to come — but they are the final views New Horizons captured of the KBO (officially named 2014 MU69) as it raced away at over 31,000 miles per hour (50,000 kilometers per hour) on Jan. 1. The images were taken nearly 10 minutes after New Horizons crossed its closest approach point.
LAUREL, Md. (JHUAPL) — The wonders – and mysteries – of Kuiper Belt object 2014 MU69 continue to multiply as NASA’s New Horizons spacecraft beams home new images of its New Year’s Day 2019 flyby target.
This image, taken during the historic Jan. 1 flyby of what’s informally known as Ultima Thule, is the clearest view yet of this remarkable, ancient object in the far reaches of the solar system – and the first small “KBO” ever explored by a spacecraft.
LAUREL, Md. (JHUAPL PR) — This movie shows the propeller-like rotation of Ultima Thule in the seven hours between 20:00 UT (3 p.m. ET) on Dec. 31, 2018, and 05:01 UT (12:01 a.m.) on Jan. 1, 2019, as seen by the Long Range Reconnaissance Imager (LORRI) aboard NASA’s New Horizons as the spacecraft sped toward its close encounter with the Kuiper Belt object at 05:33 UT (12:33 a.m. ET) on Jan. 1.
During this deep-space photo shoot – part of the farthest planetary flyby in history – New Horizons’ range to Ultima Thule decreased from 310,000 miles (500,000 kilometers, farther than the distance from the Earth to the Moon) to just 17,100 miles (28,000 kilometers), during which the images became steadily larger and more detailed. The team processed two different image sequences; the bottom sequence shows the images at their original relative sizes, while the top corrects for the changing distance, so that Ultima Thule (officially named 2014 MU69) appears at constant size but becomes more detailed as the approach progresses.
All the images have been sharpened using scientific techniques that enhance detail. The original image scale is 1.5 miles (2.5 kilometers) per pixel in the first frame, and 0.08 miles (0.14 kilometers) per pixel in the last frame. The rotation period of Ultima Thule is about 16 hours, so the movie covers a little under half a rotation. Among other things, the New Horizons science team will use these images to help determine the three-dimensional shape of Ultima Thule, in order to better understand its nature and origin.
The raw images included in the movie are available on the New Horizons LORRI website. New Horizons downlinked the two highest-resolution images in this movie immediately after the Jan. 1 flyby, but the more distant images were sent home on Jan. 12-14, after a week when New Horizons was too close to the Sun (from Earth’s point of view) for reliable communications. New Horizons will continue to transmit images – including its closest views of Ultima Thule – and data for the next many months.
LAUREL, Md. (NASA PR) — NASA’s New Horizons spacecraft flew by a small, distant world in the Kuiper Belt on New Year’s Day – the place, officially designated 2014 MU69 and nicknamed Ultima Thule, is 4 billion miles from Earth. No spacecraft has ever explored a world so far away.
Several weeks before that flyby the New Horizons team gave people around the world the opportunity to “beam” their name and a choice of messages, at the speed of light, toward New Horizons and Ultima Thule on flyby day – ¬and 30,547 people ultimately signed on. “Happy 2019!” was the top choice, selected by 8,100 participants, followed by “Keep on Exploring!” sent by 6,800 participants.

LAUREL, Md. (JHUAPL PR) — Data from NASA’s New Horizons spacecraft, which explored Kuiper Belt object Ultima Thule earlier this week, is yielding scientific discoveries daily. Among the findings made by the mission science team in the past day are:
Initial data analysis has found no evidence of rings or satellites larger than one mile in diameter orbiting Ultima Thule.
Data analysis has also not yet found any evidence of an atmosphere.
The color of Ultima Thule matches the color of similar worlds in the Kuiper Belt, as determined by telescopic measurements.
The two lobes of Ultima Thule — the first Kuiper Belt contact binary visited — are nearly identical in color. This matches what we know about binary systems which haven’t come into contact with each other, but rather orbit around a shared point of gravity.
“The first exploration of a small Kuiper Belt object and the most distant exploration of any world in history is now history, but almost all of the data analysis lies in the future,” said Alan Stern of the Southwest Research Institute in Boulder, Colorado.
LAUREL, Md. (JHUAPL PR) — NASA’s New Horizons spacecraft flew past Ultima Thule in the early hours of New Year’s Day, ushering in the era of exploration from the enigmatic Kuiper Belt, a region of primordial objects that holds keys to understanding the origins of the solar system.
LAUREL, Md. (JHUAPL PR) — Years before a team of researchers proposed a mission called New Horizons to explore the dwarf planet Pluto, NASA’s Hubble Space Telescope had already made initial observations of the world at the dim outer fringes of our celestial neighborhood. Over many years, Hubble’s pioneering observations repeatedly accomplished what ground-based telescopes could not — imaging features on Pluto’s surface, finding new Plutonian moons, and tracking down a destination to visit after Pluto — an even tinier, icy object in a vast region of small worlds beyond the orbit of Neptune called the Kuiper Belt.
Video Caption: NASA’s New Horizons team trained mobile telescopes on an unnamed star (circled) from a remote area of Argentina on July 17, 2017. A Kuiper Belt object 4.1 billion miles from Earth — known as 2014 MU69 — briefly blocked the light from the background star, in what’s known as an occultation. The time difference between frames is 200 milliseconds, or 0.2 seconds. This data will help scientists better measure the shape, size and environment around the object. The New Horizons spacecraft will fly by this ancient relic of solar system formation on Jan. 1, 2019. It will be the most distant object ever explored by a spacecraft.
LAUREL, Md. (JHUAPL PR) — NASA’s New Horizons spacecraft is bearing down on Ultima Thule, its New Year’s flyby target in the far away Kuiper Belt. Among its approach observations over the past three months, the spacecraft has been taking hundreds of images to measure Ultima’s brightness and how it varies as the object rotates.
LAUREL, Md. (JHUAPL PR) — NASA’s New Horizons spacecraft is set to fly by a distant “worldlet” 4 billion miles from the Sun in just six days, on New Year’s Day 2019. The target, officially designated 2014 MU69, was nicknamed “Ultima Thule,” a Latin phrase meaning “a place beyond the known world,” after a public call for name recommendations. No spacecraft has ever explored such a distant world.
