The International Treaty on the Principles for the Activities of States in the Exploration and Use of Outer Space, including the Moon, was adopted by the UN in 1966 and ratified by key powers, including the USSR, the USA and later China.
Jamie Matthews, professor emeritus of astronomy at the University of British Columbia, said the claims to the Moon have no legal basis.
The professor emphasized that even past US landings on the Moon do not give the country the right to lay claim to the satellite.
WASHINGTON, September 7 - RIA Novosti. The moon is common, and anyone’s claims to it have no legal basis, Jamie Matthews, emeritus professor of astronomy at the University of British Columbia, told RIA Novosti.
"No one can lay claim to the moon. That's what the Outer Space Treaty says," Matthews said when asked to comment on Trump's post on Truth Social.
As the scientist said, even past US landings on the Moon do not give the country the authority to lay claim to the satellite. “The US sending 12 people to the Moon 50 years ago does not mean anything in the context of its ownership,” the professor emphasized.
Trump previously published a picture with a satellite and the Earth in the background, signing: “The Moon is ours” and adding an American flag to the message.
The “Treaty on Principles for the Activities of States in the Exploration and Use of Outer Space, Including the Moon and Other Celestial Bodies” was adopted by a resolution of the UN General Assembly on December 19, 1966. The Soviet Union ratified it the following May, the United States in October, and China joined in December 1983. At the moment, the document is supported by 118 countries.
“Outer space, including the Moon and other celestial bodies, is open to exploration and use by all States, without discrimination of any kind, on the basis of equality and in accordance with international law, with free access to all areas of celestial bodies,” the agreement states.
The Moon Treaty adopted by the UN General Assembly in 1979 was not so successful. In subsequent years, the US leadership expressed disagreement with the document at the level of the executive and legislative branches. Currently, 18 countries have joined it. Modern experts point out that the agreement was a failure from the very beginning, since Russia, China and the United States did not want to sign and ratify it.
“After a decade of negotiations, the agreement was ultimately not signed,” NASA’s website says in an archived publication, “On the History of Lunar Management.”

An asteroid with a diameter of about a meter, named CERNQ52, will enter the Earth's atmosphere over the Indian Ocean on Sunday evening at 19:12 Moscow time, according to data from ESA and Mount Lemmon Observatory, RIA Novosti reports citing Crimean astronomer Alexander Yakushechkin.

Researchers mapped the 124 million neural connections in a male fly's brain and compared it to a female fly, identifying differences that influence aggression, courtship and behavior.

University of Hawaii professor Kwok Fai Cheng told RIA Novosti that a collision of the Earth with a large asteroid could cause a supertsunami and catastrophic consequences for civilization, but the likelihood of such an event, including a possible collision with the Apophis asteroid in 2029, remains very low.

Russian scientists from the All-Russian Research Institute of Medicinal and Aromatic Plants have found that casuarictin, contained in sea buckthorn leaves, suppresses the growth of cancer cells. The effect was confirmed by two methods: the MTT test and direct counting of living and dead cells. The scientists plan to study the cytotoxicity, antioxidant profile and bioavailability of the compound for possible pharmaceutical use.

The summer of 2026 in Russia became the warmest in the history of meteorological observations since 1891, said Mikhail Leus, leading specialist at the Phobos weather center. Records were recorded in the Urals and Siberia, as well as in a number of other countries.

Researchers from the Institute of Zoology of the Chinese Academy of Sciences have created a technology for replacing strength training with an injection with myografts. The method can help bedridden patients and elderly people, and in the future it can become available to Russians after testing.
