For decades, Venus was imagined as Earth’s twin. A warm ocean world hidden beneath thick clouds. Some scientists even believed it might support life. Then the data came back, and the illusion collapsed.

In this episode of Still Unexplained, we explore how Venus became one of the most hostile planets in the solar system and why its transformation still raises unsettling questions. What exactly went wrong on a planet so similar to our own? Was Venus always doomed, or did something trigger a catastrophic runaway greenhouse effect? And could Venus be showing us a possible future for Earth?

Percy Fawcett vanished into the Amazon jungle in 1925 while searching for a legendary ancient civilization he called the Lost City of Z. He never returned.

In this episode of Still Unexplained, we follow Fawcett’s final expedition into one of the most unforgiving environments on Earth and examine the clues he left behind. Was Z a real advanced civilization hidden deep in the rainforest, inspired by Indigenous knowledge and early accounts of lost cities? Or did obsession, illness, or hostile encounters seal his fate?

From cryptic letters and conflicting rescue reports to modern discoveries that suggest complex ancient societies once existed in the Amazon, this episode explores how myth, archaeology, and human determination collide in one of exploration’s greatest unsolved mysteries.

The Hanging Gardens of Babylon are remembered as one of the Seven Wonders of the Ancient World, yet no physical evidence of them has ever been found.

In this episode of Still Unexplained, we explore the mystery through a different lens, tracing the legend beyond Babylon and into the powerful Assyrian Empire, where some historians believe the gardens may have actually existed. Were they built by an Assyrian king in Nineveh and later misattributed by Greek writers? Or were the gardens a myth shaped by centuries of retelling?

A story of ancient engineering, Assyrian ambition, and a wonder that may have been misplaced by history itself.
