Harvard astrophysicist Avi Loeb joins Brian Keating to discuss a groundbreaking observation: the HiRISE camera on NASA’s Mars Reconnaissance Orbiter has imaged 3I/ATLAS, a rare interstellar visitor, from the vantage point of Mars.

In this episode, we explore:

• What HiRISE detected and why it matters for planetary science.

• How interstellar objects like ʻOumuamua and 3I/ATLAS challenge our theories.

• Why Mars may become an ideal outpost for detecting future interstellar visitors.

• The implications for astrobiology, planetary defense, and our search for extraterrestrial technology.

✨ Just as the 1977 “Wow! Signal” jolted radio astronomers with a one-time unexplained burst, 3I/ATLAS may be its optical cousin—an anomalous, fleeting, but potentially transformative messenger. Loeb even calculated that 3I/ATLAS’s trajectory passed within about one degree of the Wow! Signal’s sky position, making the connection more than metaphorical. Ignoring such rare alignments risks repeating history: anomalies slip through our fingers while orthodoxy insists nothing unusual happened. The Wow! Signal warned us of the danger of complacency; 3I/ATLAS reminds us that cosmic surprises often lurk at the margins of expectation, carrying lessons we may miss if we force every mystery into old categories.

🚀 EXCLUSIVE: Avi Loeb Reveals What HiRISE Just Saw on Mars! 🌌

Harvard astrophysicist Avi Loeb joins me to discuss the latest revelations about interstellar object 3I/ATLAS as it makes its closest approach to Mars. From HiRISE images to unusual chemistry, polarization anomalies, and even a potential link to the Wow! Signal, this conversation explores whether 3I/ATLAS is a natural comet—or a possible technological artifact. Along the way, we cover censorship from Galileo to today’s UAP debates, the “Sputnik moment” of interstellar objects, and what a global response might look like.
