On March 26, 2024, the world collectively gasped as a massive container ship, the Dali, lost control and plowed into the landmark Francis Scott Key Bridge in Baltimore. The busy four-lane bridge suffered a catastrophic collapse and crashed into the Patapsco River. Six highway workers were killed, and the Port of Baltimore – a crucial link in the global shipping chain on the Eastern Seaboard of the United States – was blocked by thousands of tons of twisted steel and concrete. How did a modern ship lose all power and propulsion? And why did the bridge fail so catastrophically? Follow the high-stakes rescue and recovery, the efforts to reopen the port, and the investigations into what went wrong and how many other crucial bridges are at risk. (Premiered February 26, 2025 at 9 pm on PBS)

For over two centuries, archaeologists have hailed Pompeii as a sophisticated city at the heart of an advanced ancient civilization. But a series of new excavations is painting a much more complex picture of the city tragically buried by the eruption of Mount Vesuvius in 79 CE. New archaeological finds – including 2,000-year-old lines of graffiti, human remains, and artifacts from ancient homes and businesses – are revealing a city of both staggering wealth and extreme poverty, dependent on slavery, and riven by political conflicts, violence, and riots. Before Vesuvius rumbled, the jewel of the ancient Roman Empire hid a very dark side. (Premiered February 19, 2025 at 9 pm on PBS)

Archaeologists uncover new truths about Pompeii, a wealthy Roman playground with dark secrets.

Pompeii's Secret Underworld

On a remote hillside in modern-day Turkey sits Göbekli Tepe, the oldest temple on Earth. For centuries, archaeologists believed it was a religious center built by nomadic hunter-gatherers before the rise of civilization. But groundbreaking new evidence reveals that a sophisticated community of settled hunter-gatherers, not nomads, lived here year-round for centuries. This startling discovery could be the missing link in humanity's momentous transition from hunting to farming. Follow experts as they use new digs and shattered skulls to piece together a captivating story that could forever change our understanding of the roots of civilization. (Premieres February 25 at 9 pm on PBS)

Small mammal ancestor emerging from burrow

Uncover the surprising ancient origins of mammals, a story that began long before the dinosaurs' reign. Surveying Earth's tumultuous past reveals how some of our earliest ancestors, the therapsids – creatures that looked like reptiles but were starting to develop mammalian traits – survived multiple global catastrophes. Through remarkable adaptations like burrowing and the emergence of warm-bloodedness, they forged a lineage that persevered against all odds. Fascinating fossil clues and cutting-edge science reveal how a small, resilient group of animals faced extinction events, outlived giants, and ultimately gave rise to the diverse world of mammals we know today, including us. (Premiering February 11, 2026 at 9 pm on PBS)

Decoding the Universe: Cosmos

When we look at the world at the tiniest scales in the subatomic realm, things get weird – very weird. Welcome to the quantum universe, where particles can spin in two directions at once, observing something changes it, and something on one side of the galaxy can instantly affect something on the other, as if the space between them didn’t exist. Buckle up for a wild ride through the discoveries that proved all of this to be true and paved the way for the digital technologies we enjoy today – and the powerful quantum sensors and computers of tomorrow. Premiered November 6, 2024 at 9 pm on PBSCorrection: The original version of this film had misplaced punctuation, which falsely implied that in 1974, Stephen Hawking was the first to predict black holes. The film, captions, and transcript have been amended to clarify that in 1974, Stephen Hawking first predicted the phenomenon now known as Hawking radiation, referred to in the film as the “Achilles’ heel” of black holes.

Dive into the universe at the tiniest – and weirdest – of scales.

A skeleton of a whale in a desert-like area.

In Egypt’s Sahara Desert, massive skeletons with strange skulls and gigantic teeth jut out from the sandy ground. This fossil graveyard, millions of years old, is known as the “Valley of the Whales.” Now, paleontologists have unearthed a whole new species of ancient whale dating to 43 million years ago, and this predator wasn’t just able to swim – it also had four legs and could walk. Follow scientists as they search for new clues to the winding evolutionary path of mammals that moved from the land into the sea to become the largest animals on Earth. (Premiered January 31, 2024 at 9 pm on PBS.)

Sir David Attenborough investigates a unique site in southern England where amateur fossil hunters uncovered giant mammoth bones and evidence of Neanderthals. A team of paleontologists and archaeologists soon discover that the site preserves rare evidence of the extinct beasts and early human inhabitants of Britain dating to over 200,000 years ago. What skills did the early humans have to help them survive during the Ice Age? How did they hunt and protect themselves against formidable creatures such as mammoths? With hands-on experiments with replicas of Neanderthal-era spears and stone tools, the world of prehistoric Britain comes to life. (Premiered February 16, 2022)
