Could Aliens See Us?

What Earth’s Technosphere Reveals

What Will Earth Look Like in 1000 Years? Will humanity collapse, thrive, or colonize the stars—and could alien civilizations detect us?

Join senior planetary astronomer Dr. Franck Marchis for a fascinating conversation with Dr. Jacob Haqq-Misra, astrobiologist and lead author of a groundbreaking study exploring 10 possible futures for Earth’s technosphere—the global network of our technologies—and what these futures mean for the search for extraterrestrial intelligence (SETI).

From stable zero-growth societies to interstellar expansion, Dr. Haqq-Misra’s team models how Earth’s trajectory might look over the next millennium and what clues we might be sending into space. Could future Earth resemble a sci-fi utopia—or become invisible to alien observers?

Learn how technosignatures like atmospheric pollution (yes, even nitrogen dioxide!) could help us find—or hide from—civilizations across the galaxy.

Whether you’re into space exploration, science fiction, or the future of humanity, this interview pes deep into the cosmic implications of our technological choices.
