A cubic meter of lunar soil might be one of our best bets for finding physical proof that another advanced civilization once existed somewhere in the Milky Way, according to a new paper to be published in the International Journal of Astrobiology.

Astronomers searching for extraterrestrial intelligence have traditionally focused on a specific, narrow band of the radio spectrum. However, a new survey presented at the Royal Astronomical Society‘s National Astronomy Meeting (NAM2026) in Birmingham suggests that this approach may overlook a significant portion of the available frequencies.

The frequencies most often investigated by SETI (Search for Extraterrestrial Intelligence) programs are those between 1.42 and 1.66 GHz. This range, known as the ‘water hole’, is situated between the natural radio emissions of hydrogen and hydroxyl, the two molecules that make up water. Astronomers have regarded this quiet section of the spectrum as a reasonable place for interstellar communication, because any civilization acquainted with these molecules would probably also decide to send and receive signals in search of in that specific region.

Louisa Mason, who is carrying out research as a PhD student at the University of Manchester, focused on investigating frequencies outside the water hole range. To carry out the first SETI survey with that telescope, she used archived data from the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile. She analyzed data originally collected for other astronomical studies instead of requesting new observation time.

Hunting for Signals in Unclaimed Territory

Mason focused on two narrow frequency bands in the ALMA Band 3 data, looking for narrowband signals that might be the result of technology rather than natural astrophysical origins. In the four observations that she examined, she did not discover any candidates for technosignatures above her detection threshold.

“For decades, SETI searches have concentrated on a relatively small part of the radio spectrum. We wanted to ask what might happen if we looked somewhere very different,” Mason said. “The millimetre and submillimetre radio bands remain almost completely unexplored for SETI, so this is really about opening up a new area of parameter space to search.”

A lack of results does not rule out the possibility of alien transmitters. It only means that none appeared in this specific region of the sky and frequency range. Mason describes the survey as a proof of concept, showing that high-frequency telescopes like ALMA could play a much larger role in future SETI efforts.

A Much Bigger Haystack Than Anyone Realized

The research also revealed a gap in how astronomers count the stars they have actually examined. Each time a telescope observes a single target, it also collects light from many other stars in the same field of view. Researchers refer to this as “stellar bycatch.”

Previous SETI surveys have made this bycatch estimate based on the Gaia catalog, which is the European Space Agency‘s survey of the stars. However, Gaia has certain limitations such as its magnitude cutoffs, uncertainties when measuring distant stars, and difficulties in crowded areas. To overcome these limitations, Mason used the Besançon Galactic Model, a simulation of the Milky Way’s stellar population that includes stars that are too faint or too far away for Gaia to detect.

When Mason applied the model to a previous survey of 1,327 telescope observations, the estimated number of stars observed increased from about 288,000 with Gaia to over 6.1 million with the galactic simulation.

“One of the most exciting things about this work is realizing that we’ve surveyed many more stars than initially thought,” Mason said. “Even a very small observation can contain a huge number and diversity of stars that we might never have intended to study. By combining high-frequency observations with galactic simulations, we can better understand exactly what we’ve searched and where we should look next.”

Recommendations for SETI

Mason carried out this research in collaboration with Professor Michael Garrett, Dr. Andrew Siemion, and Dr. Kelvin Wandia. The team argues that expanding both the radio frequencies searched and the number of stars included could reduce the influence of human assumptions on SETI strategies. Whether these broader searches will detect technosignatures missed by traditional water-hole surveys remains unknown.

For decades, the possibility of discovering extraterrestrial intelligence has captured the imagination of scientists, sci-fi enthusiasts, filmmakers, and the public alike.

In line with such efforts, the IAA SETI Committee and the uNHIdden Foundation, two separate not-for-profit organizations, have recently released updated rules for evaluating and disclosing detections, and preparing for public preparedness in the event of potential disclosure of extraterrestrial intelligence.

With the release of director Steven Spielberg’s new alien film Disclosure Day, nearly coinciding with the recent release of the government records from the Department of War related to UAP, it seems a growing number of individuals, from the film industry to the science community, have extraterrestrials and “disclosure” on their minds. 

The IAA SETI Committee Rules 

In June 2026, the International Academy of Astronautics (IAA) approved a major update to the protocols governing the evaluation, verification, and communication of evidence related to extraterrestrial intelligence. The revised guidelines were designed to address a modern information environment shaped by social media, artificial intelligence, and the rapid pace of the 24-hour news cycle.

Professor Michael Garrett, Sir Bernard Lovell Chair of Astrophysics, led the international effort to revise the long-standing post-detection protocols used by researchers engaged in the search for extraterrestrial intelligence. The updated guidelines have since been formally ratified by the IAA.

“The information environment we operate in today is vastly more complex than it was in 2010,” said Garrett, Chair of the IAA SETI Committee, in a statement. “In an era of deepfakes, automated misinformation, and instant global connectivity, a single unverified claim could trigger confusion or panic. These new protocols ensure that scientists maintain the highest standards of evidence before making announcements to the world.”

The revised declaration reflects the broader scope of modern SETI and technosignature research. Since the previous guidelines were adopted in 2010, advances in technology have enabled scientists to investigate the entire electromagnetic spectrum, including excess infrared heat signatures that could indicate megastructures, optical laser emissions, and even multi-messenger signals.

The updated framework also addresses modern challenges, including protections for researchers who may face harassment, doxxing, or intense media scrutiny. It further emphasizes the importance of distinguishing verified scientific data from viral rumors, hoaxes, or terrestrial interference.

New Contact Rules at SETI

At the heart of the new guidelines is a familiar scientific principle: extraordinary claims require extraordinary evidence.

Under the revised protocols, no public announcement should be made until a signal or artifact has been rigorously verified by independent organizations using different instruments and methodologies.

“We do not shout ‘alien’ the moment we see a strange blip,” said Garret in a statement. “The scientific method demands we check, check again, and then ask others to check. Only when we have reached a consensus that a signal is credible do we bring it to the world.”

While the protocols explain how to share discovery news, they make one rule clear: no reply should be sent.

“The threshold for ‘extraordinary evidence’ is subjective,” Siemion says. “Because of the vast diversity of modalities in which a technosignature might manifest, it is impossible to state explicitly the criteria that would meet this threshold under all circumstances.”

“In the case of a coherent electromagnetic signal, like a narrowband carrier or a series of laser pulses, an example of ‘extraordinary’ would be if we repeatedly detected the signal at the same location with multiple independent observatories,” Siemion adds.

He also noted that, for a transient signal, compelling evidence might include multiple lines of data indicating that it traveled through interstellar space. Determining whether a phenomenon truly originated from extraterrestrial technology would likely be a lengthy process, with evidence presented, challenged, and reassessed over time.

The declaration reinforces that any response to extraterrestrial intelligence would be a decision for all humanity and should only occur following international consultation, particularly through the United Nations.

With the updated declaration now ratified by the IAA Board, it will be shared with stakeholders, including the United Nations. A formal presentation of the protocols is scheduled for the International Astronautical Congress (IAC) in Türkiye later this year.

“The release of these updated rules and protocols marks an important step in acknowledging both the radically different media landscape that science functions within today, and the vastly expanded efforts in terms of technology and resources being deployed in the search for intelligent life beyond Earth,” said Bill Diamond, President and CEO of the SETI Institute and IAA SETI Committee member. “We applaud Prof Garrett’s leadership in developing these new protocols and the IAA for their ratification.” 

First Contact and Humanity’s Mental Health

Another nonprofit organization has taken a different approach, focusing on the potential psychological and public-health implications of disclosure. The uNHIdden Foundation, whose mission is to support mental health related to Unidentified Anomalous Phenomena (UAP), recently released a preparedness framework addressing the societal impact of a paradigm-shifting discovery.

If governments prepare for natural disasters, pandemics, and other low-probability, high-impact events, should humanity also consider preparing for the possibility of contact with another intelligent civilization?

On June 8, uNHIdden Foundation Founder and Chairman John Priestland, alongside clinical spokesperson Dr. Martin Abbas, launched what they describe as the first public-health preparedness framework focused on disclosure-related scenarios.

Developed by healthcare practitioners, physicians, clinical psychologists, and public-health specialists, “Preparing for Disclosure: A Public Health Framework for Paradigm-Shifting Revelations” examines how society might reduce harm, build resilience, and support individuals processing a profound shift in humanity’s understanding of its place in the universe.

“This report is not a prediction. It is a preparedness exercise,” Priestland says. “Governments prepare for all kinds of low-probability, high-impact events.”

“Our view is that if a paradigm-shifting disclosure were ever to occur, we should at least have thought about the human consequences in advance,” Priestland added. 

The report suggests that certain groups could be more vulnerable to disclosure-related distress, including individuals with pre-existing mental health conditions, those facing socioeconomic hardship, UAP experiencers, highly religious individuals, and some STEM professionals. The authors emphasize that the report neither predicts disclosure nor attempts to judge future discoveries; rather, it argues that preparedness is a prudent response to the possibility of transformative new information.

David Whitehouse, former BBC Science Correspondent, wrote the report’s foreword, arguing that planning is essential should such a discovery ever occur.

The new framework proposes several practical actions to be taken, which include:

• Reducing stigma surrounding anomalous experiences and disclosure-related concerns
• Building public resilience and psychological flexibility
• Developing trusted sources of information and support
• Creating community conversation groups and peer-support networks
• Strengthening mental health preparedness and triage capability
• Encouraging collaboration between healthcare professionals, researchers, government, and civil society

The report argues that stronger community resilience, clearer communication during periods of uncertainty, and improved mental-health support would be critical not only during a disclosure event but during any large-scale societal disruption.

Ultimately, the question remains whether humanity is truly prepared—or whether a globally coordinated framework is still lacking. Voices ranging from the UAP community to figures within the U.S. government have argued that the public is ready. However, only time will tell what the result may be if confirmation of extraterrestrial intelligence were to arrive—and how humanity will collectively respond to the discovery.
