The Sun. It's a big ball of fire, right? Apparently not. In fact, what's going on inside of the Sun took us some time and knowledge of physics to finally figure out: stellar fusion. Let's talk about the different kinds of fusion, and how we're trying to adapt it to generate power here on Earth.

Finding planets is old news, we now know of thousands and thousands of the places. But the terrible irony is that we can only see a fraction of the planets out there using the traditional methods of radial velocity and transits. But the new telescopes will take things to the next level and image planets directly.
