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...

Astronomer Jean-Luc Margot has come up with a new definition for planets that may help us categorize worlds outside of the solar system, and we may have also discovered a new dwarf planet within the solar system!

What's happening over and under Pluto's fascinating surface.

Here's a Dwarf Planet Song about our solar systems new Dwarf Planet Candidate 2014 UZ224! Brought to you by KLT!

I'm sure most of us grew up with the knowledge that Pluto was our solar system's ninth planet. So what changed about the definition?

Apart from all the planets in the solar system, we've discussed smaller objects as well, like asteroids and comets, and also dwarf planets. While Pluto is the most famous dwarf planet, Eris is actually slightly more massive, making it...

Is Pluto a Planet? examines the history of Pluto and describes why it is no longer considered a planet.

Many of us grew up with the knowledge that Pluto was our solar system's ninth planet. So what changed about the definition?

What new findings have we discovered about our favourite little world, Pluto?

In this video, the topic of discussion is the Kuiper Belt, a region in our solar system that extends from the orbit of Neptune. It is similar to the asteroid belt but much larger, and is home to three recognized dwarf planets, including...

Researchers have discovered the most similar planet yet to Earth, 1,400 light-years away. Kepler-452b orbits its star in 385 days, just 20 days longer than our own year. Its star is just 4% larger, a billion and a half years older, and...

The video discusses the existence of planets within and beyond our solar system, exploring the potential for supporting other forms of life. It highlights the discovery of numerous exoplanets and the ongoing search for Earth-like planets...

On July 14, 2015, New Horizons flew by Pluto. Scientists have used the data from the mission so far to uncover active geology, an enormous canyon, a unique case of chemical coloration, and more. What else might we discover as we venture...

Astronomers using the Hubble Space Telescope discovered a moon orbiting dwarf planet Makemake -- the third largest known object past the orbit of Neptune, about two thirds the size of Pluto. Further observations of this moon may...

Physics Girl astrophysics series - Brown Dwarfs are among the most recently observed objects in the universe. They have at MOST 8% the mass of the Sun. The lower mass boundary is not known! So they are halfway between stars and gas giant...

Astronomers have discovered the first known dwarf planet to host a ring system. This animation shows the 43-mile-wide ring of particles and debris that encircles the planet. The egg-shaped world, called Haumea, is located in the Kuiper...

How to Find an Exoplanet

I took a trip to one of Austin's famous moontowers so I could put the enormity of our solar system into perspective. With the help of a grapefruit, and a lot of walking, you'll get an idea of just how tiny everything is out there!!

Not all of the objects in the solar system are named after Greek and Roman gods -- some are named after literary figures, movie stars, and don't get us started on what people think Earth is really called.
