Scientists discover underground cave on the moon that could shelter astronauts on future trips to space
Scientists have confirmed a cave on the moon, not far from where Neil Armstrong and Buzz Aldrin landed 55 years ago, and suspect there are hundreds more that could house future astronauts.
An Italian-led team reported Monday that there’s evidence for a sizable cave accessible from the deepest known pit on the moon. It’s located at the Sea of Tranquility, just 250 miles (400 kilometers) from Apollo 11’s landing site.
The pit, like the more than 200 others discovered up there, was created by the collapse of a lava tube.
Researchers analyzed radar measurements by NASA’s Lunar Reconnaissance Orbiter, and compared the results with lava tubes on Earth. Their findings appeared in the journal Nature Astronomy.
The radar data reveals only the initial part of the underground cavity, according to the scientists. They estimate it’s at least 130 feet (40 meters) wide and tens of yards (meters) long, probably more.
“Lunar caves have remained a mystery for over 50 years. So it was exciting to be able to finally prove the existence” of one, Leonardo Carrer and Lorenzo Bruzzone of the University of Trento, wrote in an email to the Associated Press.
During NASA’s Apollo program, 12 astronauts landed on the moon, beginning with Armstrong and Aldrin on July 20, 1969.
The findings suggest there could be hundreds of pits on the moon and thousands of lava tubes.
The Nature study said that the cave could be a “promising site for a lunar base, as it offers shelter from the harsh surface environment and could support long-term human exploration of the Moon.”
However, building habitats from scratch would be more time-consuming and challenging, even when factoring in the potential need of reinforcing the cave walls to prevent a collapse, the team of researchers said.
British astronaut Helen Sharman told CBS partner BBC News that humans could shelter in lunar pits like this one in 20 to 30 years, but that they may need “jet packs or a lift” to get out due to the depth of the cave.
Rocks and other material inside these caves — unaltered by the harsh surface conditions over the eons — also can help scientists better understand how the moon evolved, especially involving its volcanic activity
Scientists around the world are constantly adding to the archive of moon research. Just weeks ago, China’s Chang’e 6 lunar probe returned to Earth after collecting rock and soil samples from the moon’s surface. Chinese scientists hope that findings will shed light on differences between two sides of the moon, which have unique geographical features.

A picture is emerging of the suspect who officials say pointed a high-powered rifle at former president Donald Trump on a Florida golf course Sunday afternoon.
Ryan Wesley Routh, 58, was armed with an AK-47-style rifle and was 300-500 yards away from Trump when members of the former president’s Secret Service detail spotted him, according to Palm Beach County Sheriff Ric Bradshaw. Routh was a few holes ahead of where the president was golfing at the Trump International Golf Course in West Palm Beach, officials said.
Members of the Secret Service detail opened fire at Routh, according to law enforcement officials. It’s not clear if Routh fired any shots. Bradshaw said a witness saw a man jumping out of the bushes and fleeing in a black Nissan. The car was pulled over and the driver detained and identified as the suspect. Law enforcement found the rifle, a scope, two backpacks with ceramic tile and a GoPro camera in the bushes at the scene.
The FBI and U.S. Secret Service are investigating the incident, which the FBI said “appears to be an attempted assassination of former President Trump.”
As the investigation continues, here’s what we know about Routh:

A decades-long criminal history
Routh’s most recent address is listed in Hawaii, but he spent most of his life in North Carolina, according to property records. Routh owned Camp Box Honolulu, a shed-building company, according to his LinkedIn profile. The account also says that he studied at North Carolina Agricultural and Technical State University and graduated in 1998.
Records show his problems with the law go back to the 1990s and include less serious charges, like writing bad checks. But in 2002, he was charged with a felony — possession of a weapon of mass destruction — according to North Carolina Department of Corrections records.
Between 2002 and 2010, Routh was also charged with a number of misdemeanors, including a hit-and-run accident, resisting arrest and a concealed weapons violation, records show.
Suspect criticized Trump online
Routh voted Democratic in the 2024 primary election in North Carolina, and he voted in person, according to the North Carolina State Board of Elections. He appears to be registered as an unaffiliated voter.
His X account, which has now been suspended, included a number of posts about Trump.
“@realDonaldTrump While you were my choice in 2106, I and the world hoped that president Trump would be different and better than the candidate, but we all were greatly disappointment and it seems you are getting worse and devolving,” he wrote in a June 2020 post. “I will be glad when you gone.”
He also referenced the July 13 assassination attempt on Trump in multiple posts, suggesting that President Biden and Vice President Harris should visit the injured and attend the funeral of the Pennsylvania rally-goer who was killed.
A Facebook account under Routh’s name was no longer online on Sunday evening.
Ukraine supporter
Routh was passionate about fighting for Ukraine, even traveling overseas to fight in the country’s war against Russia in 2022.
“I am coming to Ukraine from Hawaii to fight for your kids and families and democracy.. I will come and die for you,” he wrote on X.
In one post on LinkedIn, he shared a photo of himself in Kyiv, Ukraine’s capital.
A CBS News review of Routh’s social media shows his pro-Ukraine views seeped into his public statements as well. He urged people, even those who didn’t have military skills, to take up arms for Ukraine. He was interviewed by several news organizations, including The New York Times and Semafor in 2023, and Newsweek Romania in 2022. He was quoted about his efforts to recruit volunteer fighters to aid Ukraine in its fight against Russia’s invasion, though it wasn’t clear whether he had succeeded.
“This is about good versus evil,” he told Newsweek Romania.
