 Hello, and welcome to our 2015 update. This past year marked the 25th anniversary of the Hubble Space Telescope. We're going to see caverns carved out of dust by new stars. We're going to get a look at the Vale Nebula moving. We'll see it expand. We'll see through the Eagle Nebula. We'll take a very close look at the Andromeda Galaxy. We'll see a galaxy on the edge of the local void. Also in 2015, CERN reopened the Large Hadron Collider after a two-year closure to upgrade the power to almost twice what it was when they found the Higgs boson. At these levels, it might be able to find dark matter. And Hubble discovered a supernova, predicted it, and found it due to gravitational lensing around dark matter. So with two key 2015 updates, I thought it'd be appropriate to dig deeper into just what dark matter is. So we'll conclude this update with a deep look at dark matter. But first, let's take a look at the updates from inside the Milky Way.
