The false-colour images were taken at the furthest ever point from Earth captured by a spacecraft - they're also the closest ever images of objects in the Kupier Belt.
The image captured by New Horizons is from a distance father than that of the "Pale Blue Dot" image of Earth taken by NASA's Voyager 1. The Voyager was 3.75 billion miles from Earth when that composite of 60 images looking back at the solar system was taken, and it's cameras were shut off shortly after.
Soon after the Pale Blue Dot picture was taken, the cameras were turned off on Voyager 1, leaving its record unchallenged for the next 27 years.
"LORRI broke its own record just two hours later with images of Kuiper Belt objects 2012 HZ84 and 2012 HE85 - further demonstrating how nothing stands still when you are covering more than 1.1 million kilometres of space each day", researchers said. Both are floating in the Kuiper Belt, an area on the edge of our solar system that NASA's spacecraft is now exploring.
That New Year's flight past MU69 will be the farthest planetary encounter in history, happening 1.6bn km beyond the Pluto system - which New Horizons famously explored in July 2015. Specifically, New Horizons is targeting 2014 MU69, a mysterious object (or pair of two objects) which Alan Stern, mission principal investigator from the Southwest Research Institute (SwRI), has called "provocative" and a "scientific bonanza".
New Horizons was launched on January 19, 2006.
The New Horizons spacecraft is healthy and is now in hibernation. (Pluto is one of these dwarf planets.) 2014 MU69 is almost a billion miles beyond Pluto, which itself is 4.67 billion miles (7.5 billion km) beyond Earth.
"And now, we've been able to make images farther from Earth than any spacecraft in history", Stern added.
New Horizons is the fastest spacecraft ever launched, traveling at a speed of 700,000 miles (1.1 million kilometers) per day. In fact, the all we know about it has come from the Hubble Space Telescope (used to discover the object in 2014) and a comprehensive observation campaign last summer, in which the New Horizons team gathered data on MU69 as it passed in front of three stars. They're also the closest-ever images of Kuiper Belt objects. New Horizons is one of only five shuttles which has managed to reach the escape velocity required to exit the solar system.
