- Episode 10: Cosmic Recycling Anticipating a Glorious Death of our Sun
Our Sun has been a constant source of energy for the past 4.5 billion years but it will eventually run out of fuel (in about 5 billion years). While this will be bad for the inhabitants of the Earth (and probably for inhabitants of any other planet in our Solar system), this solar demise will be spectacularly beautiful. We know this by looking at the end stages of other stars in our Galaxy. Let’s talk about the future of our own Sun.

- Episode 12: Look at the Farthest Galaxy in the Universe (yet) Discovered
Our universe had a beginning 13.8 billion years ago. We now live in the Milky Way galaxy. But what were the earliest galaxies like? Astronomers can directly look at these young galaxies by looking farther out in space.
- Episode 13: Ibn Sina and the Supernova of Year 1006
In the year 1006 C.E. Ibn-Sina observed a bright new star appear in the night sky. He diligently took notes as the star faded over the next 3 months. This was a supernova. Ibn-Sina did not know its nature, but his notes are shedding new light into the nature of these exploding stars!
- Episode 14: A Planet Around Our Neighboring Star Proxima Centauri
Humans have always dreamt of traveling to other stars. Now we have a destination. Astronomers have found a planet, slightly bigger than the Earth, around a star only 4 light years away. Furthermore, the planet is in the “Habitable Zone” of its star, meaning that it is orbiting its star at a distance where water can exist in liquid form!
- Episode 15: The Mysterious Star
Alien technology? No, well probably not! Nevertheless, “Tabby’s Star” is currently one of the most mysterious stars in the universe. Astronomers are having a hard time explaining its behavior, at least with what we know from astronomy. But this is also a great example of how scientists approach an unusual phenomenon with imagination, creativity, and a healthy dose of skepticism.
