Black Holes

Season 1 · Episode 1

Thursday, May 15, 2025 • Duration 03:02

We delve into these mysterious giants: What exactly are black holes? Are they really black? And if they are… how can we see them?

Another Dwarf Planet in the Solar System!

Season 1 · Episode 3

Thursday, June 19, 2025 • Duration 03:24

In this episode of Cosmic Brew, we dive into the discovery of a possible new dwarf planet at the edge of our solar system, nicknamed 2017 OF201. We explore what makes a dwarf planet different from a regular planet, revisit the story of Pluto’s controversial reclassification, and learn how astronomers used clever algorithms and massive datasets to spot this tiny, faraway world. With an orbit that takes 25,000 years to complete, this icy object—and others like it—may hold key clues about how the solar system formed and evolved.

Rain on Titan: Saturn’s Largest Moon

Season 1 · Episode 2

Sunday, June 1, 2025 • Duration 02:58

In this episode, we explore Titan — Saturn’s largest moon and one of the most Earth-like worlds in the solar system. With its thick atmosphere, lakes of liquid methane, and potential for hosting life, Titan could even serve as a future energy reserve.

The Vera Rubin Observatory

Season 1 · Episode 4

Saturday, June 28, 2025 • Duration 03:08

The Vera Rubin Observatory has begun operations in Chile, aiming to photograph the entire southern sky every four days with an ultra-powerful telescope and a 3,200-megapixel camera. Named after pioneering astronomer Vera Rubin, the observatory will help track asteroids, monitor changing celestial objects, and discover billions of galaxies — offering new clues about the universe’s structure, dark matter, and our cosmic origins.

Interstellar Visitor

Season 1 · Episode 6

Saturday, July 12, 2025 • Duration 03:26

In this episode, we explore the recent discovery of 3I/ATLAS, a comet traveling through our solar system from another star. As the third known interstellar object, it offers a rare chance to study materials from beyond our stellar neighborhood. Detected by NASA’s ATLAS program in Chile, this cosmic traveler reminds us how much we still have to learn about other planetary systems — and the importance of watching the skies, just in case something unexpected comes to visit.

Relativity in your pocket

Season 1 · Episode 5

Monday, July 7, 2025 • Duration 03:38

In this episode, we break down Einstein’s mind-bending theory of relativity and explore how it affects something as everyday as your phone. You’ll learn why time doesn’t tick the same for everyone, how speed and gravity can mess with your clock, and why your GPS wouldn’t work without Einstein’s equations.

Light Pollution

Season 2 · Episode 2

Thursday, January 15, 2026 • Duration 04:16

In this episode of Cosmic Brew, we explore light pollution—what it is, how it impacts astronomy, wildlife, and human health, and what we can do about it. From confused moths and off-course birds to sea turtle hatchlings lured away from the ocean and disrupted human sleep cycles, the effects of artificial lightingstretch far beyond the night sky. But the good news? With smarter lighting choices, we can protect ecosystems, our health, and the stars above.

Euclid Mission - Astronomers need your help!

Season 2 · Episode 1

Friday, January 2, 2026 • Duration 02:18

The Euclid mission is opening an extraordinary new window on the Universe by delivering images of more than 10 million galaxies, allowing scientists to study how cosmic structure has evolved over the last 10 billion years. By mapping galaxies across time, Euclid helps us probe the mysterious 95% of the Universe made up of dark matter and dark energy, the unseen forces shaping how galaxies form and how the Universe expands. What makes this effort especially exciting is that anyone can take part: through the Galaxy Zoo project, people around theworld can help classify galaxies and directly contribute to cutting-edge cosmology, turning curiosity into real scientific discovery.

The European Space Agency’s official Euclid page explains the mission’s goals, instruments, timeline, and how it will map the dark Universe.

This site dives deeper into the scientific questions behind Euclid, including dark matter, dark energy, and the large-scale structure of the cosmos.

Galaxy Zoo lets anyone help scientists classify real galaxies from missions like Euclid, turning clicks and curiosity into genuine astronomical research.
