Episode Details

On this episode of Kalam Astro, host Alya Al-Nuaimi brings you stories of human courage, cosmic fireworks, and one of the greatest planetary mysteries in our solar system.

We open with a triumphant homecoming: four astronauts — Commander Jessica Meir, pilot Jack Hathaway, French ESA astronaut Sophie Adenot, and Russian cosmonaut Andrey Fedyaev — splashed down safely in the Pacific Ocean off California on October 8th, after spending 10 incredible months aboard the International Space Station. Traveling aboard a SpaceX Dragon capsule at 28,000 km/h, orbiting Earth roughly 16 times a day, their return is a testament to international cooperation in space and the resilience of the human spirit.

Then we turn our eyes to the far reaches of the universe to discover blazars — cosmic lighthouses more powerful than anything in the known universe. These supermassive black holes are aimed directly at Earth, beaming jets of energy across billions of light-years, and scientists have just discovered a spectacular new one.

And finally, we explore one of astronomy's most fascinating questions: why are Earth and Mars so different? Born in the same solar neighborhood, at roughly the same time, from the same cosmic materials — yet one is a vibrant, living world, and the other is a cold, barren desert. The answer may lie in their ancient histories and the role of water, magnetism, and cosmic collisions.

We also look ahead to the 2026 Chandra eclipse and what promises to be a landmark year for astronomy in 2026–2027!

Tune in, look up, and keep exploring with Kalam Astro! 🌌
