The Sky at Night – Ancestral Skies

The Sky at Night – Ancestral Skies: This month, “The Sky at Night” joins forces with BBC Ideas to explore an exciting crossroads of archaeology and astronomy, revealing the fascinating secrets of our ancestral skies. Humanity has always been drawn to the stars, from the sun guiding early explorers across the earth to today’s astronomers decoding the mysteries of the cosmos. But as our modern world expands, are we losing the essential link to these deep, ancient skies?

Imagine standing beneath a vast, starlit sky—the kind that our ancestors once gazed at in wonder, using the stars to navigate both the earth and their place in the universe. These stars were more than points of light; they were storytellers, guiding them through both time and space. From ancient stone circles marking celestial events to the satellites now orbiting above us, our story with the night sky is a rich one.

However, modern civilization, with its sprawling cities and bright lights, threatens to sever this timeless bond. As we uncover the wonders of our shared heritage in the stars, we must ask: what happens if we lose our ancestral night skies forever? What will we miss when the light from the past fades under the artificial glow of progress?

On the scenic Bodmin Moor in Cornwall, George Dransfield joins archaeoastronomer Carolyn Kennett at the mysterious Goodaver stone circle—a site hidden away from public view for decades. Rich in history and tradition, these ancient stones were placed to mark celestial events, aligning with the sun, moon, and stars in ways that held deep significance for those who lived long ago. The Goodaver stone circle tells a story of humanity’s relationship with the universe, reflecting an understanding of the skies that we are only beginning to rediscover.

Carolyn, along with other archaeoastronomers, finally has the chance to study these alignments firsthand as the site prepares to open to the public in November. This is a profound moment for researchers, allowing them to assess the connections between the stones and the horizon, unlocking secrets about our ancestors’ relationship to the cosmos. What forgotten stories will be revealed as the sun rises and sets over Goodaver once again? What new insights will we gain about the beliefs, rituals, and lives of the people who built these incredible monuments?

To think of it, this is not just about stones and stars. It is about time travel—looking back thousands of years into a world where the night sky was a constant, a shared experience that linked every person, every family, every community. We often think of the past as distant, but places like Goodaver bring it within reach, urging us to listen to the whispers of those who came before. As the alignment of these stones comes to light, it provides a physical, tangible link to an ancient worldview that respected the harmony between Earth and sky, reminding us that humanity has always looked upwards in awe and curiosity.

Meanwhile, in Cambridge, Chris Lintott and Maggie Aderin-Pocock delve into archaeology—but perhaps not the kind you might expect. At the Whipple Museum of the History of Science, Maggie connects with Dr. Alice Gorman, an Australian space archaeologist, to explore what we should preserve from humanity’s journey into space. Imagine future generations visiting museums to witness relics of humanity’s early adventures beyond Earth—the first satellites, the landing sites on the Moon, even the tools used by early astronauts.

These artifacts are more than just technological achievements; they are emblems of our pioneering spirit, our desire to reach beyond what we know, and our hunger to explore the unknown. What fragments of our spacefaring past will help future people understand how we first ventured into the cosmos? From the Moon to Mars, we are not just explorers; we are creators of history in space, leaving marks that may one day be precious clues to our beginnings in the galaxy.

This concept of space archaeology shifts our perspective from Earth to the cosmos—encouraging us to think about how we want to be remembered as a species. Will we leave a positive legacy, something that tells the story of our creativity, our ingenuity, and our quest to connect with the universe? Space is not just the final frontier; it is a vast archive of human endeavor, and the decisions we make now about what to preserve will impact how future generations understand this critical era in human history.

Chris also heads over to Cambridge’s Department of Archaeology to unearth the surprising and intriguing concept of Galactic Archaeology. It might sound like science fiction, but it’s a real scientific effort to reconstruct our galaxy’s past by studying what’s visible today. Picture our galaxy as an ancient city, where stars are the crumbling ruins that hold secrets to the past.

Astrophysicist Dr. Payel Das and anthropologist Professor Robert Foley are breaking new ground with an extraordinary approach—using phylogenetic trees, models traditionally employed in evolutionary biology, to piece together the history of galaxies. Just as ancient cities were built layer by layer, each generation of stars is created from materials left by those that came before. These cosmic relics contain clues to their ancestry, giving us the opportunity to reconstruct a grand story of the Milky Way’s history. It’s like finding fossils of stars, remnants of their chemical footprints, and using them to map out how the galaxy evolved over billions of years.

The idea of Galactic Archaeology asks us to consider the universe as a living, evolving entity—one whose history is still being written, one star at a time. The light from ancient stars that reaches us today is a message from the distant past, and by decoding it, we gain insights into not only how our galaxy came to be but also our own origins within it.

What were the conditions like in those early generations of stars? How did they contribute to the development of planets, of solar systems, of life itself? The universe’s history is interwoven with our own, and by examining these ancient cosmic relics, we can better understand how we fit into the larger story of the cosmos.

While Cambridge brings new perspectives to understanding the past, Pete Lawrence is on Bodmin Moor, waiting for night to descend at the Exmoor Dark Skies Festival. There, he meets Jo Richardson to explore why our night skies—the same skies our ancestors would have seen—are so critical to preserve. As day fades into twilight, they reflect on how artificial lighting is erasing our connection to the stars.

It’s not just about losing beautiful views; it’s about losing a part of who we are. The bright lights of cities, though mesmerizing, have been affecting the health of humans and animals alike—disrupting sleep, migration, and behaviors long shaped by the natural cycle of day and night. Imagine how different our lives would be if we could still see the Milky Way arching across the sky every night, reminding us of our place in a vast and mysterious universe.

Jo explains that dark skies are a form of cultural heritage—one that is rapidly disappearing. The natural night sky was an essential part of human life, serving as a canvas on which stories, myths, and scientific discoveries were painted. Today, artificial lighting washes out the stars, and with them, the inspiration and sense of wonder they bring. It’s not just an environmental issue; it’s a cultural one, a human one. As Pete and Jo wait for the clouds to clear, they are reminded of the importance of keeping places like Exmoor protected, where people can connect to the night sky and feel the same wonder that has captivated humanity for millennia.

Throughout this captivating journey, “The Sky at Night” invites us to rediscover and protect our shared heritage. From ancient stone circles aligned to the heavens, to relics left on the Moon, and stars holding stories from billions of years past, we uncover profound connections between archaeology and astronomy. These two disciplines, though seemingly worlds apart, come together to tell a unified story: that our fascination with the stars has always shaped who we are and how we see ourselves in the universe. By understanding the past—whether it’s the legacy of ancient stargazers or the remnants of the first stars—we can better navigate our future.

Are we truly so different from our ancient ancestors, standing beneath the same dark sky, hearts filled with wonder? Perhaps by understanding the past—both on the ground and in the sky—we can illuminate the way forward, preserving not just the physical artifacts of human civilization but also the deep, instinctual need to look up, to dream, and to understand our place in the vastness above.

Our story with the stars is ongoing, and it is up to us to protect that link for future generations. Join us this month, as we explore how the past meets the present, and archaeology meets astronomy, to illuminate the enduring relationship between humanity and the night sky. Together, we can ensure that the legacy of our ancestors, written in the stars, continues to shine brightly for all who follow.

Conclusion The Sky at Night – Ancestral Skies

As we draw our journey to a close, we realize that the night sky, which once connected our ancestors across centuries and continents, remains a timeless bond linking us to the cosmos. Whether marked by the careful alignment of ancient stones, the launch of satellites, or the distant light of long-dead stars, our relationship with the skies is an enduring testament to our desire to seek, explore, and understand.

The wonder our ancestors felt as they looked up at the heavens is the same awe that fuels today’s scientists and dreamers. The Goodaver stone circle reminds us that the night sky was once a tool for survival, a cultural compass guiding rituals, harvests, and spiritual practices. It was our ancient way of navigating life’s uncertainties, and though we’ve advanced in technology, our need for the stars—as symbols, as inspiration—remains constant.
