Names proposed by the public are now officially acknowledged by astronomers.

NASA has a whole lot of fancy image-gathering hardware on Earth and in space, and we’ve seen countless of stunning snapshots taken from here on Earth as well as nearby planets like Mars, Jupiter and Saturn. The pictures are often gorgeously detailed eye candy, but the latest batch of images from the space agency is remarkable for an entirely different reason. Captured by NASA’s New Horizons spacecraft, the images were gathered at a greatest distance from Earth than any in the history of mankind.
So, just how far is “the farthest ever”? Right around 3.79 billion miles. Yeah, it’s kind of crazy. There are three images in total, each focusing on a different distant object. The subjects include the ‘Wishing Well’ star cluster as well as two large objects in the Kuiper Belt which have never been observed from such a distance before.
“New Horizons has long been a mission of firsts — first to explore Pluto, first to explore the Kuiper Belt, fastest spacecraft ever launched,” New Horizons Principal Investigator Alan Stern, of the Southwest Research Institute in Boulder, Colorado, notes in a statement. “And now, we’ve been able to make images farther from Earth than any spacecraft in history.”
The images, as seen above (Kuiper Belt objects) and below (Wishing Well cluster), are somewhat grainy and not the most detailed we’ve seen from NASA, but that doesn’t make the feat any less remarkable.
New Horizons originally launched way back in early 2006, and it the spacecraft has made close passes of a number of planets during its more than a decade of cruising through our Solar System. Its primary mission was set to last roughly 10 years, but was extended once it became clear that the spacecraft was healthy enough to continue sending back observations for a while longer.
Its new extended mission will wrap up in early 2021 after it performs a number of flybys of large objects in the Kuiper Belt that scientists want to learn more about. However, that might not be the last we hear from New Horizons, as its power source could continue to provide life into 2026 and beyond. If it makes it that long, NASA plans to use the spacecraft to study the outer heliosphere.
The New Horizons spacecraft has Pluto well and truly in the rear-view mirror by now, as it’s on the way to check out the Kuiper Belt. But the magic of space exploration is that long after the probe has departed, scientists still have mountains of data to sift over.
To celebrate the one-year anniversary of New Horizons’ flyby of Pluto, NASA’s team of scientists has put together a two-minute video of a Pluto flyby, based on elevation data and observations made by New Horizons during its short but glorious mission.
NASA provides a handy guide to what you’re actually seeing in the Pluto flyby:
This dramatic Pluto flyover begins over the highlands to the southwest of the great expanse of nitrogen ice plain informally named Sputnik Planitia. The viewer first passes over the western margin of Sputnik, where it borders the dark, cratered terrain of Cthulhu Macula, with the blocky mountain ranges located within the plains seen on the right. The tour moves north past the rugged and fractured highlands of Voyager Terra and then turns southward over Pioneer Terra — which exhibits deep and wide pits — before concluding over the bladed terrain of Tartarus Dorsa in the far east of the encounter hemisphere.
There’s also a second video for Charon, Pluto’s largest Moon. Both videos have had the topology of the surface exaggerated to make for more interesting viewing, and the colors are also not accurate to what the naked human eye would see.
New Horizons followed five failed proposals to send hardware to Pluto.
Convection within the ice renews the surface, keeps it crater-free.
