Hey Pluto, Sedna, Haumea, Makemake Et al.: You’ve got company!
While searching for distant galaxies and supernovae, the Dark Energy Survey’s powerful 570-megapixel digital camera spotted a few other moving “dots” in its field of view. Turns out, the DES has found more than 100 previously unknown trans-Neptunian objects (TNOs), minor planets located in Kuiper Belt of our Solar System.
A new paper describes how the researchers connected the moving dots to find the new TNOs, and also says this new approach could help look for the hypothetical Planet Nine and other undiscovered worlds.
Guess you never know what you’ll find once you start looking!

On July 14th, 2015, the New Horizons made the first-ever flyby of Pluto. As if that wasn’t enough, the mission made history again with the flyby of the Kuiper Belt Object (KBO) 2014 MU69 on December 31st, 2018. This constituted the farthest encounter from Earth with a celestial object, which the team had nicknamed Ultima Thule – a mythical northern island beyond the borders of the known world in Medieval literature.
Unfortunately, this name has generated some controversy due to the fact that it is also the name white supremacists use to refer to a mythical homeland. So with the consent of the tribal elders and representatives of the Powhatan nations, the New Horizons’ team recommended a new name for the KBO. Henceforth, it will be known as “Arrokoth“, the word for “sky” in the Powhatan/Algonquian language.

Got your 3D glasses handy? Then prepare for the most realistic views of Ultima Thule yet! Yes, it seems that every few weeks, there’s a new image of the Kuiper Belt Object (KBO) that promises the same thing. But whereas all the previous contenders were higher-resolution images that allowed for a more discernible level of detail, these images are the closest we will get to seeing the real thing up close!

In 2015, the New Horizons mission became the first robotic spacecraft to conduct a flyby of Pluto. In so doing, the probe managed to capture stunning photos and valuable data on what was once considered to be the ninth planet of the Solar System (and to some, still is) and its moons. Years later, scientists are still poring over the data to see what else they can learn about the Pluto-Charon system.
For instance, the mission science team at the Southwest Research Institute (SwRI) recently made an interesting discovery about Pluto and Charon. Based on images acquired by the New Horizons spacecraft of some small craters on their surfaces, the team indirectly confirmed something about the Kuiper Belt could have serious implications for our models of Solar System formation.

What’s going on in the distant reaches of our Solar System? Is there a Planet 9 out there?
Out in the frigid expanse of our System, there are bodies on orbital paths that don’t make sense in terms of our eight-planet Solar System. There seems to be an undiscovered body out there, several times more massive than Earth, shaping the orbits of some Kuiper Belt Objects (KBOs), and driving astronomers to look deeper and more thoroughly into the extreme reaches of our System.
What they’re looking for is the mysterious, and so far unproven, ninth planet.

On December 31st, 2018, the New Horizons probe conducted the first flyby in history of a Kuiper Belt Object (KBO). Roughly half an hour later, the mission controllers were treated to the first clear images of Ultima Thule (aka. 2014 MU69). Over the course of the next two months, the first high-resolution images of the object were released, as well as some rather interesting findings regarding the KBOs shape.
Just recently, NASA released more new images of Ultima Thule, and they are the clearest and most detailed to date! The images were taken as part of what the mission team described as a “stretch goal”, an ambitious objective to take pictures of Ultima Thule mere minutes before the spacecraft made its closest approach. And as you can no doubt tell from the pictures NASA provided, mission accomplished!

On December 31st, 2018, NASA’s New Horizons mission made history by being the first spacecraft to rendezvous with the Kuiper Belt Object (KBO) named Ultima Thule (2014 MU69). This came roughly two and a half years after New Horizons became the first mission in history to conduct a flyby of Pluto. This latest encounter led to some stunning images of the KBO as the spacecraft made it’s approach.
But of course, these were not the last images New Horizons was going to capture of this object. While making its flyby of Ultima Thule on New Year’s Day, the spacecraft took a number of images that revealed something very interesting about Ultima Thule’s shape. Rather than consisting of two spheres that are joined together, Ultima Thule is actually made up of two segments – one that looks like a pancake, the other a walnut.

The Kuiper Belt, or the Edgeworth-Kuiper Belt, is home to ancient rocks. Kuiper Belt Objects, or KBOs, are remnants of the early planet-formation days of our Solar System. Small KBOs, in the 1 km. diameter range, have been theorized about for decades, but nobody’s every found one.

On December 31st, 2018, NASA and the New Horizon‘s team (plus millions of people watching the live stream at home) rang in the New Year by watching the New Horizons mission make the first rendezvous in history with a Kuiper Belt Object (KBO). About thirty minutes after the probe conducted its flyby of Ultima Thule (2014 MU69), the mission controllers were treated to the first clear images ever taken of a KBO.
Since the first approach photographs were released (which were pixilated and blurry), the New Horizons team has released new images from the spacecraft that show Ultimate Thule in color and greater detail. It’s appearance, which resembles that of a snowman, beautifully illustrates the kinds of processes that created our Solar System roughly four and a half billion years ago.

In July of 2015, NASA’s New Horizons mission made history when it became the first spacecraft to conduct a flyby of Pluto. Since that time, the spacecraft’s mission was extended so it could make its way farther into the outer Solar System and become the first spacecraft to explore some Kuiper Belt Objects (KBOs). It’s first objective will be the KBO known as 2014 MU69, which was recently given the nickname “Ultima Thule” (“ultima thoo-lee”).
