As we continue our search for earth-like, potentially habitable worlds, we come across an interesting triple-star system called Gliese 667. The smallest of these three stars, Gliese 667 C, is a red dwarf with several planets, one of...

Our solar system has just one star in it, the sun. But this is actually not the most common situation for systems. Most systems are multi-star systems, with binary systems being extremely common. These are systems where two stars orbit...

Humans have been to the moon, and we will almost certainly set foot on Mars very soon. But then what? Can we colonize other places in the solar system? What about beyond our solar system? How will we get there? What kinds of energy will...

This video explains how mathematicians use coordinate planes to show the location of objects in space. It introduces the concept of horizontal and vertical number lines, which intersect at the origin to create a coordinate plane. The...

NASA is about to launch a new spacecraft to look at the universe in X-ray light. The Imaging X-Ray Polarimetry Explorer, IXPE, will look at extreme objects such as black holes, neutron stars, and supernovae, asking fundamental questions...

Okay, so we are about 150 million years into the lifetime of the universe. We've got a bunch of hydrogen and helium and not much else. But then gravity takes over, and boom! We've got stars! How, you ask? Well you'd better watch this!

The video discusses how stars are classified based on their color and surface temperature. The narrator explains the concept of luminosity, which is the total energy emitted per second by a star, and how it differs between different...

This video provides a detailed overview of the structure and location of our solar system, including the orbits of different celestial bodies and the gravitational forces that keep them in place. It also explores the location of our...

We've learned a lot about stars! We know how they form, and we know that most of them exist in galaxies. But how are they arranged within galaxies? And are there different types of galaxies or are they all the same? There is a lot to...

China is creating an artificial star that burns at temperatures eight times hotter than our sun by replicating its energy-generating, hydrogen fusion process on Earth.

We learned a bit about general relativity and the curvature of spacetime, both earlier in this series, as well as in the modern physics course. But let's talk a bit more about the astronomical observations that corroborate this theory....
