Time to expand our view and encompass the entire universe. Some of the most dramatic events originate from tidal forces caused by gravity: other worlds, galaxies, black holes and even entire clusters of galaxies are under this influence.

The Milky Way has gobbled up dozens of dwarf galaxies and added them to its structure. Today we’re going to look at the ongoing hunt for the wreckage of past mergers. And what we’ve discovered about dwarf galaxies in general.
Is it globular clusters or is it globeular clusters? It doesn’t matter, they’re awesome and we’re here to update you on them.
There are several companies working on missions and techniques to harvest minerals from asteroids. What other resources are out there that we can use?
Thanks to Cassini and other spacecraft, we’ve learned a tremendous amount about the icy worlds in the Solar System, from Jupiter’s Europa to Saturn’s Enceladus, to Pluto’s Charon. Geysers, food for bacteria, potential oceans under the ice and more. What new things have we learned about these places?
If there’s one place we’ve learned more about in the last 10 years, it’s Mars. What have we learned about Elon Musk’s future home?
Time for another update, this time we’re going to look at what’s new with supernovae. And once again, we’ve got good news, lots of new stuff to report.
Another update episode, this time we look at what’s new and changed in the research of black holes. And it’s here that we find a lot of substantial new discoveries in the field, so much has been discovered since we first covered black holes a decade ago.
