A Bunch of New Names for Pluto’s Surface Features Were Just Approved

Pluto is getting some new names. In the past, prior to the New Horizons mission, there wasn’t much to name. But now that that spacecraft has flew past Pluto and observed it up close, there’s some features that need naming.

Now the IAU (International Astronomical Union) has approved a new set of names for 14 of the dwarf planet’s surface features.

An Insulating Layer of Gas Could Keep a Liquid Ocean Inside Pluto

In July of 2015, NASA’s New Horizons mission made history by becoming the first spacecraft to ever conduct a flyby with Pluto. In addition to providing the world with the first up-close images of this distant world, New Horizons‘ suite of scientific instruments also provided scientists with a wealth of information about Pluto – including its surface features, composition, and atmosphere.

The images the spacecraft took of the surface also revealed unexpected features like the basin named Sputnik Planitia – which scientists saw as an indication of a subsurface ocean. In a new study led by researchers from the University of Hokkaido, the presence of a thin layer of clathrate hydrates at the base of Pluto’s ice shell would ensure that this world could support an ocean.

Now You Can See MU69 in Thrilling 3D

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!

The Latest Images of Ultima Thule are in, and they are the Sharpest Yet!

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!

New Horizons took this shot of MU69 as it sped away from its encounter

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.

Here it is, the high resolution photo of MU69 we’ve all been waiting for.

On December 31st, 2018, NASA’s New Horizons mission made history by being the first spacecraft to rendezvous with a 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. Much like the encounter with Pluto, the probe’s rendezvous with Ultima Thule led to a truly stunning encounter image.

And now, thanks to a team of researchers from the John Hopkins University Applied Physics Lab (JHUAPL), this image has been enhanced to provide a more detailed and high-resolution look at Ultima Thule and its surface features. Thanks to these efforts, scientists may be able to learn more about the history of this object and how it was formed, which could tell us a great deal about the early days of the Solar System.

The Pictures are Here! New Horizons Close Up View of 2014 MU69

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.

New Horizons Sees its Next Target for the First Time: Ultima Thule. Flyby Happens January 1, 2019

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”).
