Arrokoth, an asteroid in the Kuiper Belt, is the most distant object ever explored by the New Horizons spacecraft. And it's covered in sugar. Here's why that might be important for understanding the nature of life...

Some funky orbits near the Kuiper Belt are hinting towards a brand new planet, the elusive ‘Planet X.’ Our friends Mike Brown and Konstantin Batygin of Caltech are working hard to finally spot the potential gas giant through powerful...

You know what a planet is, right? A big round thing that orbits a star. Uh, not so fast. The surprisingly vicious debate over the planetary status of Pluto has given us a fascinating glimpse into what a scientific definition really is....

After Pluto's demotion to dwarf planet in 2006, our solar system went from having nine planets to eight. But about a decade later, some astronomers proposed there was another planet, larger than Earth, hiding in the Kuiper Belt. And in...

Now that we’re done with the planets, asteroid belt, and comets, we’re heading to the outskirts of the solar system. Out past Neptune are vast reservoirs of icy bodies that can become comets if they get poked into the inner solar system....

Earlier this spring NASA announced a new research model that predicts that ocean worlds are far from rare, and our galaxy might be full of them. And a new study examines evidence that Pluto may have had an underground ocean all along!

There’s no question that comets have been regarded as some of the most beautiful things in the night sky for thousands of years. But why are their heads often green but never their tails?

Hank fills us in on the four exploratory missions to space that he is most excited about - New Horizons is going to Pluto and the Kuiper belt; Juno is on it's way to Jupiter; Dawn is exploring two large asteroids; Rosetta will land on a...

SciShow Space brings you NEWS FROM THE FUTURE, with details about the space missions to look forward to in 2015.

The solar system is enormous, and includes the Kuiper Belt and the Scattered Disc, both of which turn out to be really weird in some pretty awesome ways.

Physicist Freeman Dyson suggests that we start looking for life on the moons of Jupiter and out past Neptune, in the Kuiper belt and the Oort cloud. He talks about what such life would be like -- and how we might find it.

The new year is off to a great start for space exploration! New Horizons has passed the farthest object ever visited by a spacecraft, and China put a lander on the dark side of the Moon!

The event that gave us our moon may have also given us the elements necessary for life and scientists might have found a very tiny piece of our solar system's past way out in space.

New Horizons is on its way to Ultima Thule, the most distant object a spacecraft has ever visited. And scientists have created the sugar component of DNA under extraterrestrial conditions.

Hank interviews Dr. Alex Harrison Parker about New Horizons' Pluto flyby, what's next for the probe, and what we can anticipate learning about the solar system's history!

The New Horizons spacecraft has given us lots of clues about the early days of our solar system, but we don't always have to travel billions of kilometers to peer into our past.

An asteroid streaked across Arizona's night sky, and we have a new theory on where the hypothetical Planet Nine came from.

The constellation of Orion has one shoulder marked by a bright red star called Betelgeuse, but over the last year it's dimmed enough to notice with the naked eye! and mission scientists are shedding some light on how Arrokoth and other...

We've already learned a lot about the solar system, but sometimes the most fascinating things are what we DON'T know.

Several companies are developing 3D printers that might eventually be able to print organs...in space! What!?

Scientists have spotted a galaxy from the early origins of the universe, and found evidence to support the existence of a 9th planet in our solar system.

As of 1989, mankind had successfully sent craft to every known planet in the solar system except one: Pluto. Located in an mysterious region called the Kuiper Belt, Pluto is a scientific goldmine, and could hold clues to the formation of...

This week in SciShow Space News we bring you the latest on what to expect from NASA's New Horizons deep space mission and what asteroids to watch for in the coming years!

Since New Horizons flew by Pluto on July 14, 2015, it's completely redefined what we know about the dwarf planet and its largest moon Charon. New Horizons' mission will continue to be full of surprises, but here's what we've learned so far
