Chris and I decided to find out when humans realized that meteorites came from beyond Earth: it could be a lot older than it was once thought! Egyptologist Dr Victoria Almansa-Villatoro joins us to discuss meteorite artifacts and intriguing hieroglyphs from Ancient Egypt.
We are talking about ancient aliens. (No, not the racist conspiracy theory!) We look into the concept of extraterrestrials over history and how it originated. Who were the first recorded people who pondered about life outside Earth?
In this episode, we tackle the classic concept of sound in space, what can we measure, and why it is important that some sound waves move through the cosmos.
Our position inside the Milky Way doesn't give us an advantageous view of our galaxy. But that doesn't mean we haven't found a way around it. Joined by Dr GyuChul Myeong, we explore how we make sense of the Milky Way and its past collision with the Gaia-Sausage galaxy.

The Astroholic Explains Xmas Special is inspired by Italo Calvino's Cosmicomics on the 100th anniversary of the author's birth. Join us for an imaginative tale, not fantasy nor sci-fi, but one based on science facts: the formation of elements in stars and how they spread across the universe. ✨

We don't know and will likely never know what happened before the Big Bang, but Chris is curious about it, so we take a journey in the land before time and space!
Conspiracy theories and misconceptions about the Moon extend far beyond the Moon-landing! In this episode, we take a trip 4.5 billion years into the past to witness how Luna came to be.
