The NASA probe passed the first New Year's Day the furthest object ever attempted, an unknown object named Ultima Thule.
In the next few months it will send images and other observations back to earth from an area outside of Pluto.
It took about ten hours for the signal to come home from the New Horizons spacecraft, which is now 6.5 billion miles from Earth.
The radio signal was picked up by one of NASA's most important antennas in Madrid, Spain.
"We have a healthy spacecraft and have just passed the furthest passing of a celestial body ever," said Operations Manager Alice Bowman for applause and joy from the Johns Hopkins University Physics Laboratory's control team in Maryland, USA.
Reaching celestial body ever
Ultima Thule is part of a belt with hundreds of thousands of ice and rocks outside the planets of our solar system, which we have only been able to discover in the last 20 years. This is called the Kuiper Belt.
Ultima Thule is named after a term in Greek mythology, which means something like "outside the borders of the world". It was also these Romans who were called Norway, the extreme, the furthest from 2000 years ago.
So far we only have a graphic representation of Ultima Thule, made by an artist. But after a trip of 13 years New Horizons has arrived. Even a little later on Tuesday we get the first decent photo 's from Ultima Thule.
The most exciting thing now is whether they hit the telescope, so that they get the images with the highest resolution of the surface. They first get to know it in February.
There is also excitement about whether Ultima Thule, as you think, is an object that has the shape of a peanut, or that it is actually two small spheres that revolve around each other. We will know that tomorrow.
The expectation is that it will take until September 2020 to receive all the information that New Horizon has recorded, writes the BBC.
Origin of planets
The researchers believe that the celestial bodies in the Kuiper Belt can reveal how the planets were formed. The reason is that it is called in such a way that there are virtually no chemical reactions. That is why the objects have not changed and are perfectly preserved in their original form.
The team working with New Horizons hopes to get funding to investigate at least one item in the Kuiper belt.
The space probe gets its energy from plutonium and it is sufficient that it can be used until the end of the 2030.
But New Horizons is not the space probe that has traveled the farthest from the earth. At the time of writing Voyager 1 is 21.56 billion kilometers away from the earth.
