WASHINGTON (AP) — A polarizing Harvard astronomer known for splashy theories about alien visits has been tapped by the Trump administration to lead a team of outside scientists to study the national security risks posed by UFOs.
Avi Loeb, a cosmologist who studied black holes and served as head of Harvard’s astronomy department until 2020, was recently appointed to helm a new scientific advisory council tasked with investigating the origins of mysterious orbs and other objects reported by military personnel in recent years.
Loeb’s team will report to a new panel focused on UFOs, now often referred to as unidentified anomalous phenomena, or UAP. The panel was established by the Office of the Director of ɫtv Intelligence. It’s part of the push to declassify more information about the issue.
“It’s like a detective story,” Loeb said in an interview. “It’s a lot of fun, as long as you don’t pay too much attention to the critics.”
For the last decade, Loeb has been scanning the skies and seas for evidence of intelligent alien life. He began the quest in 2017 as scientists puzzled over an soaring by Earth. While others proposed it was a comet or ice chunk, Loeb said it could be a thin “light sail” detached from an alien spacecraft.
His theories have won praise in UFO circles but often put him in conflict with academic peers. Other astronomers accuse him of making exotic claims with little evidence. Some chafe at his habit of skipping the peer review process and bringing claims directly to the public.
Steve Desch, an Arizona State University astrophysicist who has challenged some of Loeb’s theories, said Loeb uses flawed methods to reach wild conclusions about alien life — all while shunning a more established branch of science searching for life beyond Earth.
Loeb’s role on the administration’s new panel casts doubt on the entire endeavor, Desch said.
“I don’t know what’s going to come of this, but we’re not going to get any closer to answering these questions with him in charge,” Desch said.
The team includes scientists, UFO activists and a billionaire
Loeb brushes his critics aside, saying they lack the imagination to consider new ideas. He’s promising a grounded approach to his work for the Trump administration. As he analyzes UAP, he’s starting with the assumption that they’re the work of humans, he said, approaching it from a national security perspective.
Nonetheless, he envisions an outcome where his work could lead to something bigger. If the government invests in better data collection on Loeb said, it could settle the alien debate once and for all.
His hand-picked team includes more than a dozen scientists and UFO activists. Among them is Timothy Gallaudet, a retired rear admiral who has controlled by “nonhuman intelligence,” claiming the United States has recovered crashed aircraft. Also on the team is Ben Lamm, a billionaire working to .
After its first meeting last month, the team sent a request to the Pentagon asking for more than 50 videos, images and other documents related to known UAP incidents. Loeb’s group meets behind closed doors, but he has vowed to brief the public and create a website to share findings.
“At a time when science is not so much celebrated, this is an opportunity to actually do good for all sides involved,” Loeb said.
New UAP board created in response to Trump’s order for transparency
Earlier this year, Trump to provide more transparency on questions of UFOs and alien life. So far, the Pentagon has released three batches of files ranging from decades-old FBI reports to more recent military videos showing orbs darting or soaring through the sky.
Trump’s directive led to the creation of a UAP Governance Board overseen by the . The board met for the first time in June, and is supported by Loeb’s team and several other advisory groups, the office said.
It comes as a bipartisan group in Congress pushes the White House to go further, with some Republicans amplifying claims the U.S. is hiding evidence of alien encounters. The White House has encouraged anyone with information to come forward. A Pentagon office that investigates UAP says it has seen no evidence of alien life.
Loeb said he doesn’t buy into cover-up theories. “My impression is the government is baffled by not being able to infer the nature of some of these objects,” he said.
Before looking for aliens, Loeb studied black holes and galaxies
Before he became known for his alien theories, Loeb was a respected cosmologist who authored hundreds of papers, specializing in black holes and the birth of galaxies. He served as chair of Harvard’s astronomy department for nearly a decade.
Loeb’s career took a turn with his “light sail” theory in 2017, which he presented in a paper and later a book. He went on to found the Galileo Project at Harvard, with a stated mission to search for artifacts from alien civilizations.
His team drew attention in 2023 when they used magnets to retrieve hundreds of small spheres from the floor of the Pacific Ocean, near the possible site of a 2014 meteor crash. After analyzing the metallic “spherules,” Loeb suggested they came from a distant planet or, alternately, from technology.
Other scholars challenged the claim, saying it was probably volcanic rock or coal ash.
Sean Kirkpatrick, a physicist who previously investigated UAP at the Pentagon’s All-domain Anomaly Resolution Office, said Loeb is “not viewed favorably” in the scientific community and lacks national security experience. He said the makeup of Loeb’s team suggests the Trump administration is more interested in fringe theories than hard science.
The White House did not respond to a request for comment about the criticism.
Loeb, meanwhile, said he aims to follow the science without distraction. “Let’s keep our eyes on the orbs,” he said, “not the social media.”
