🔭 If we discovered evidence of life beyond Earth, how would we know it was real?
From searching for microscopic traces of technology in lunar soil to uncovering clues about ancient water on Mars, SETI Institute scientists are exploring new ways to investigate the universe.
In "The Search: September 2026", we look at the science behind extraordinary discoveries, the lessons learned from false alarms, and why understanding the evidence is just as important as finding it.
🌌 Catch up on the latest research and stories from across the SETI Institute!

www.seti.org The Search September 2026 #PPOD: City Lights Across America's Heartland 🌃
The lights of cities across the United States sparkle against the darkness in this photograph taken from the International Space Station on October 18, 2026. Captured by Canadian Space Agency astronaut Joshua Kutryk approximately 417 kilometers above Earth, the view stretches from the Midwest toward the East Coast. Among the illuminated metropolitan areas are Chicago, Detroit, and New York, their sprawling networks of lights tracing the landscape a few hours before sunrise.
From orbit, artificial lighting reveals the remarkable extent of human activity across the planet. Bright concentrations mark major cities, while smaller communities and transportation corridors create intricate patterns between them. Photographs like this offer a striking perspective on the geography of human settlement and the contrast between Earth's natural darkness and the places we illuminate. They also remind us that, even from hundreds of kilometers above, humanity's presence is unmistakable.

🌍 Did astronomers detect an atmosphere around a distant rocky planet? And if so, where did the evidence go?
Located about 48 light-years from Earth, LHS 1140 b is a rocky exoplanet orbiting in its star's habitable zone. In 2024, astronomers detected a helium signature consistent with gas escaping from its atmosphere. But when they looked again in 2025, the signal was missing.
Does that mean the atmosphere disappeared? Not necessarily!
In our latest SETI Live blog, Dr. Collin Cherubim and SETI Institute astronomer Dr. Franck Marchis explore what these observations reveal about the changing atmospheres of distant worlds and their potential habitability.

www.seti.org Evidence of an Atmosphere Around a Rocky World 🌙 Have astronomers finally found an exomoon?
Researchers have found strong evidence for a planetary-mass object orbiting a brown dwarf. But there's a fascinating catch: scientists aren't sure whether it should actually be called a moon!
In this episode of the SETI Live podcast, astronomer Franck Marchis talks with researcher Kevin Hoy about the discovery, the proposed term “exosatellite,” and why the boundaries between planets and moons aren't always clear.
