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.

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.

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.

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.

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.
