First moon samples in over 40 years may alter lunar history

“Our current views need readjustment” about how long our beloved white globe remained warm and volcanically active, says a researcher.

In late 2020, a Chinese space capsule delivered fresh moon samples to Earth for the first time in about four decades, and these precious lunar rocks just revealed a new detail about our planet’s glowing companion: Its volcanoes were alive and active considerably longer than scientists thought.

“All our experience tells us that the moon should be cold and dead 2 billion years ago. But it is not, and the question is, ‘Why?'” said Alexander Nemchin, a professor of Geology at Australia’s Curtin University and author of the analysis published Thursday in the journal Science.

Alongside an expansive and international team of researchers, Nemchin discovered that some of the newly transported moon rocks contain lunar fragments from later days of the white orb’s timeline. Dated about two eons ago, these fragments are relatively young. But here’s the kicker: Those same pieces are also remnants of a volcanic eruption.

Connecting the dots, the team members realized they were looking at solid confirmation that the lunar surface was alive pretty late in the game.

“We need to dig deeper with this,” Nemchin remarked. “We are highlighting that our current views need readjustment — further research will tell how dramatic this readjustment should be.”

Welcome back, lunar research

The saga began last year in December, when China’s Chang’e 5 mission sent a spacecraft to scrape the surface of the moon and collect a variety of rock and dust samples for Earth-based analysis. It returned with about 4 pounds (2 kilograms) of extraterrestrial material.

The year 1976 marks the last time lunar samples were brought down to our home planet, an achievement of the Soviet Union’s Luna 24 mission. But before that, NASA’s Apollo missions were running the course from Earth to the moon several times — the crusades returned photographs, moon rocks and personal anecdotes of astronauts.

“There was some need and drive to do this 50 years back,” Nemchin explained. “Then, priorities changed and everybody moved to something else.” But now, he says, “we have the moon back in the focus.”

He notes lunar research is important not only from an astronomy perspective, but also because any effort to travel to the moon — or really, any space exploration — tends to expedite technologies that ultimately benefit us on Earth.

One example of such serendipitous tech comes from Australian physicists’ research in the ’90s. They developed a highly complex mathematical tool hoping to detect smeared signals of black holes that vanished in the cosmos. Unfortunately, they never found any — but their invention paved the way for modern-day Wi-Fi.

Moon rock science

“Every new sample gives us a big boost in understanding what is happening, simply because we still have so few of them,” Nemchin remarked. “Apollo samples have been worked on for the last 50 years and are still actively investigated.”

While analyzing the rocks brought back by Chang’e 5, Nemchin and fellow researchers first checked out what types were present. In particular, they were after basalt fragments, which are correlated with volcanic activity.

“We needed to get an idea about chemical composition of the fragments to be able to compare [them] to the large basaltic field visible from the orbit,” he said. “And, make sure [those] fragments represent this field of basalts and do not come from somewhere else.”

Then, the scientists confirmed specific ages of the pieces of interest. Validating that these fragments are young was one of the main goals of the mission. That’s how the team members expected to prove their hypothesis of the moon having active volcanoes more recently than textbooks suggest.

“All basalts we had before are older than 3 billion years,” Nemchin said. “We also had a few very young points determined from material ejected by very young impacts — impact melts — but nothing in between. Now we have a point right in the middle of the gap.”

Such age determinations are called crater counting, something the team hopes to continue doing in the future in order to attain the full array of rocks to map out each generation of the moon. Nemchin also notes that a few interesting chemical features were found in the basalt samples, including high iron content, which isn’t present in any other retrieved pieces of the lunar surface.

Further chemical research on the rocks, he says, will help answer new questions introduced by the team’s novel findings, such as searching for the source of heat that led to lunar volcanic activity a couple of billion years ago.

And at the end of the day, the Australian geologist emphasizes that “what is important for me in all this is that we managed to bring a large international group of people to work on the sample.”

“Somehow,” he added, “In the current situation when international travel is still rather restricted, I had more interaction with different people than in the previous years when we could move around any way we liked.”

Trump Maintains US‑Iran Negotiations Continue Amid Tehran’s Denials of Duplicity

President Trump insists that US‑Iran talks are ongoing despite Tehran’s denial of any negotiation plans, while warning that only a deal or total surrender will allow passage through the Strait of Hormuz. Conflicting statements from both sides have heightened uncertainty as the conflict enters its sixth month.

On Monday, President Donald Trump asserted that negotiations between the United States and Iran are still taking place, even after Tehran stated it has no intention of engaging in direct talks with Washington.

In a fiery Truth Social post, Trump labeled Iran’s leaders “unbelievably duplicitous,” claiming they are lying about ongoing peace talks “whether Iran wants to admit it or not.” He repeated his assertion that the United States completely controls the Strait of Hormuz, despite maritime traffic through the crucial route lingering at only a small fraction of pre‑conflict levels.

He wrote, “Nothing reaches Iran unless we allow it, and nothing will pass unless a deal—or total surrender—is achieved.”

Earlier that day, Iranian Foreign Ministry spokesperson Esmail Baghaei told reporters there is no imminent plan for U.S.–Iran negotiations, contradicting Trump’s earlier comment that talks would resume Monday afternoon. Baghaei added that Iran’s only current discussions are with Oman concerning the Strait of Hormuz.

The conflicting statements have heightened uncertainty over the peace‑talk process and the broader conflict, now in its sixth month.

Trump’s assertion about new negotiations came a day after he said on Truth Social that he had agreed to cancel a massive strike against Iran “subject to being able to rapidly make a DEAL.” He said in the same post that Iran and other Middle Eastern countries had asked him to hold off on that attack because “the perimeters of a deal has been agreed to.”

Trump has claimed dozens of times throughout the more‑than‑five‑month‑long war that a deal is at hand. No permanent deal has been signed, and a temporary ceasefire reached in June has fallen apart.

Trump has also repeatedly threatened to launch devastating strikes against Iran before backing off. After the latest example, oil prices on Monday fell and stocks surged.

BMI, a research unit of Fitch Solutions, said in a note Monday that a broader diplomatic understanding on reopening the Strait of Hormuz is still achievable this quarter, while raising the probability of its escalation scenario to 35% from 25%, citing mounting military, diplomatic and economic signs of rising U.S.-Iran tensions.

“Diplomatic progress is likely to be punctuated by periodic military flare-ups, while miscalculation by either side could trigger a renewed escalation,” BMI analysts wrote in a note. The firm said the key issue to watch is the future governance of the strait, as the Iran-Oman talks — potentially backed by Gulf states, China and the U.S. — point to efforts to build a post-conflict shipping framework.

Shipping risks persist even as diplomacy appears to be advancing. The United Kingdom Maritime Trade Operations Centre said it received a report of an incident 20 nautical miles (23 miles) northeast of Khasab, Oman — at the mouth of the strait — with a tanker’s master reporting an explosion in close proximity to the vessel at about 20:37 UTC Sunday (4:37 pm ET). The vessel and crew were safe and authorities are investigating, UKMTO said, advising ships to transit with caution.

The proposal Trump announced over the weekend calls for the U.S. and Iran to return to negotiations and continue ironing out some of the thorny issues that had derailed diplomatic efforts, according to The Associated Press, citing a regional official involved in the mediation efforts.

The official said the proposal also includes a reopening of the Hormuz Strait and halting attacks across the region, including by Iranian-backed militias in Iraq on the Arab Gulf countries and Jordan.

The U.S., for its part, will end its naval blockade on Iran and allow Tehran to export its oil, the official said, adding that no deal has been reached, although the mediation efforts remained underway.

Trump’s weekend reversal has lowered the temperature after days of escalating attacks across the Gulf. Kuwait said Saturday that Iranian forces launched a wave of drones within its airspace, with its military destroying multiple aircraft after Iran targeted critical infrastructure in the country’s north.

A parallel track with Muscat is also advancing. Iranian diplomats said Tehran was close to reaching a new arrangement with Oman to manage shipping through the Strait of Hormuz, a deal critical to preventing the war from escalating further, according to the Financial Times.

Iranian officials said negotiations over future management of the Hormuz Strait with Oman, which sits on the opposite shore of the waterway, are in their final stages. The agreed shipping route would be different from those used before, according to Iran’s Foreign Ministry spokesperson, Baghaei, adding that the new route was separate from the issue of the strait’s reopening or continued closure.

Oil Prices Slide as Trump Halts Planned Iran Strike

Oil prices dropped after Trump cancelled a planned strike on Iran, with WTI down about 5% and Brent near 5% lower. He said the move followed requests from Tehran and regional allies for a pause while a deal shaping the Strait of Hormuz and Iran’s nuclear program is negotiated.

Oil prices fell on Monday after President Donald Trump announced he had cancelled a planned strike on Iran. WTI futures dropped roughly 5% to $80.34 a barrel, while Brent slipped about 4.7% to $83.77 a barrel.

Trump said early Sunday he called off the strike after Iran and several Middle Eastern nations asked him to hold off, noting that the outlines of a deal had been agreed upon. He added that the prospective accord would entail the immediate, full opening of the Strait of Hormuz and an end to Iran’s nuclear ambitions, according to his Truth Social post.

The president had been considering another round of strikes as diplomatic hopes waned since the conflict began on February 28. He said the U.S. and Iran would meet for talks on Monday, but Iran denied any scheduled negotiations with Washington, citing PressTV. Iran’s foreign‑ministry spokesperson Esmaeil Baghaei clarified that Tehran was only discussing shipping routes through the Strait of Hormuz with Oman. In a follow‑up Truth Social message, Trump insisted that, regardless of Iran’s acknowledgment, the United States is indeed discussing a solution to a long‑standing problem created by Iran.

Oil Prices Drop as Trump Cancels Planned Attack on Iran

Oil prices fell sharply after President Trump announced the cancellation of a planned strike on Iran, citing a new deal that would open the Hormuz Strait and end Iran’s nuclear threat.

Oil prices fell sharply on Monday after President Donald Trump announced that he had called off a planned strike on Iran.

West Texas Intermediate futures, the U.S. benchmark, slipped roughly 5% to close at $80.34 per barrel, while Brent crude, the international benchmark, declined 4.7% to settle at $83.77 a barrel.

Trump made the announcement early Sunday, saying he had canceled the strike following requests from Tehran and other Middle Eastern countries.

In a Truth Social post, he wrote: “We have just been asked by Iran, and other Middle Eastern Countries, to hold off any attack in that the perimeters of a deal has been agreed to.”

The president indicated that the proposed agreement would include the immediate, complete, and total opening of the Hormuz Strait, as well as an end to Iran’s nuclear threat.

Trump had been weighing additional strikes amid diminishing prospects for a diplomatic resolution to the conflict that began on Feb. 28. He stated that the U.S. and Iran would hold negotiations on Monday.

Tehran denied that talks were planned with Washington, according to state news outlet PressTV.

Iran’s Foreign Ministry spokesman Esmaeil Baghaei said Tehran was only holding talks with Oman regarding the routes ships can use through the Strait of Hormuz.

In a subsequent Truth Social post, Trump added that whether “Iran wants to admit it or not, we are, in fact, talking of a solution to a problem that they have caused for decades.”
