Stellar

One of the fundamental questions humanity has always asked is how big is our Universe? For much of human history, people believed that Planet Earth was the very center of the entire universe. And Earth is pretty big. But compared the rest of the universe, we are infinitesimally small.

Looking up at the stars makes you wonder: what and who is out there? And why haven’t we seen any other intelligent civilizations given the vast size and age of the universe?

While Earth might be the only current confirmed source of life in our solar system, it might not stay that way for long thanks to the upcoming Mars 2020 Rover Mission as well as the Europa Clipper Mission.

On April 10, 2019, astrophysicists from the Event Horizon Telescope collaboration electrified the world with the first ever image of a black hole. How did that happen?

Dianna Cowern (aka Physics Girl) visited LIGO, one of the largest and most sensitive scientific instruments ever created, to find out how they detected gravitational waves for the first time.

In this first episode of the PBSDS mini-series, STELLAR, Space Time host Matt O'Dowd travels to the top of Mauna Kea to visit the Gemini North telescope and see just how they found this ancient Quasar and it’s massive black hole.
