TED-Ed: Could human civilization spread across the whole galaxy? - Roey Tzezana
Could human civilization eventually spread across the whole Milky Way galaxy? Could we move beyond our small, blue planet to establish colonies in the multitude of star systems out there? These questions are pretty daunting, but their...

Gamma-Ray Bursts
Gamma-ray bursts are not only incredible to study, but their discovery has an epic story all its own. Today Phil takes you through some Cold War history and then dives into what we know. Bursts come in two rough varieties: Long and...

TED: A stellar history of modern astronomy | Emily Levesque
Astronomers once gazed upon the night sky and counted every star in the galaxy by hand. The process has evolved since then, but the thirst for celestial knowledge remains the same. Join astrophysicist Emily Levesque for an anecdote-rich...

Meet the Milky Way's Last Big Meal: The Sausage Galaxy
Our Milky Way Galaxy once dined on the Sausage Galaxy, and Jupiter's auroras seem to be heavily influenced by one of its moons. It's a galaxy-eat-galaxy kind of universe out there!

How To X-Ray A Black Hole
Black holes are everywhere, including at the center of our galaxy. But because they’re invisible they’re quite difficult to study. Looking at the disks of material surrounding them, however, can give us tons of clues about how they...
