Astronomers capture the birth of planets around a baby sun outside our solar system
CAPE CANAVERAL, Fla. (AP) — Astronomers have discovered the earliest seeds of rocky planets forming in the gas around a baby sun-like star, providing a precious peek into the dawn of our own solar system.
It’s an unprecedented snapshot of “time zero,” scientists reported Wednesday, when new worlds begin to gel.
“We’ve captured a direct glimpse of the hot region where rocky planets like Earth are born around young protostars,” said Leiden Observatory’s Melissa McClure from the Netherlands, who led the international research team. “For the first time, we can conclusively say that the first steps of planet formation are happening right now.”
The observations offer a unique glimpse into the inner workings of an emerging planetary system, said the University of Chicago’s Fred Ciesla, who was not involved in the study appearing in the journal Nature.
“This is one of the things we’ve been waiting for. Astronomers have been thinking about how planetary systems form for a long period of time,” Ciesla said. “There’s a rich opportunity here.”
NASA’s Webb Space Telescope and the European Southern Observatory in Chile teamed up to unveil these early nuggets of planetary formation around the young star known as HOPS-315. It’s a yellow dwarf in the making like the sun, yet much younger at 100,000 to 200,000 years old and some 1,370 light-years away. A single light-year is 6 trillion miles.
In a cosmic first, McClure and her team stared deep into the gas disk around the baby star and detected solid specks condensing — signs of early planet formation. A gap in the outer part of the disk gave allowed them to gaze inside, thanks to the way the star tilts toward Earth.
They detected silicon monoxide gas as well as crystalline silicate minerals, the ingredients for what’s believed to be the first solid materials to form in our solar system more than 4.5 billion years ago. The action is unfolding in a location comparable to the asteroid belt between Mars and Jupiter containing the leftover building blocks of our solar system’s planets.
The condensing of hot minerals was never detected before around other young stars, “so we didn’t know if it was a universal feature of planet formation or a weird feature of our solar system,” McClure said in an email. “Our study shows that it could be a common process during the earliest stage of planet formation.”
While other research has looked at younger gas disks and, more commonly, mature disks with potential planet wannabes, there’s been no specific evidence for the start of planet formation until now, McClure said.
In a stunning picture taken by the ESO’s Alma telescope network, the emerging planetary system resembles a lightning bug glowing against the black void.
It’s impossible to know how many planets might form around HOPS-315. With a gas disk as massive as the sun’s might have been, it could also wind up with eight planets a million or more years from now, according to McClure.
Purdue University’s Merel van ’t Hoff, a co-author, is eager to find more budding planetary systems. By casting a wider net, astronomers can look for similarities and determine which processes might be crucial to forming Earth-like worlds.
“Are there Earth-like planets out there or are we like so special that we might not expect it to occur very often?”

Iranian protesters rename Tehran street after Trump, plead ‘don’t let them kill us’ amid crackdown
NEWYou can now listen to Fox News articles!
Iranian protesters intensified nationwide demonstrations over the past 24 hours, directly appealing to President Donald Trump while chanting anti-regime slogans. Footage published Wednesday showed a protester in Tehran symbolically renaming a street after Trump, while other videos captured handwritten appeals reading, “Don’t let them kill us,” Iran International reported.
Holly Dagres, a senior fellow at the Washington Institute, posted the video on X stating, “Since Trump’s comments about the Iran protests, I’ve seen numbers videos of Iranian protesters either thanking him or, in this case, renaming streets after the US president.”
The appeals came as demonstrators faced a widening security crackdown, including the deployment of armed units and tear gas near major civilian sites in Tehran.
TRUMP SIGNS ‘MAKE IRAN GREAT AGAIN’ HAT ALONGSIDE LINDSEY GRAHAM
Exiled Iranian opposition leader Reza Pahlavi said the current unrest represents a historic opportunity to end Iran’s Islamic Republic.
“In all these years, I’ve never seen an opportunity as we see today in Iran,” Pahlavi said in an interview aired Tuesday on “Hannity.”
“Iranian people are more than ever committed to bringing an end to this regime, as the world has witnessed in the last few days, the level of demonstrations is unprecedented in Iran,” he said.
Pahlavi said protests have spread to more than 100 cities and emphasized the role of Iran’s traditional merchant class, describing developments inside the country’s bazaars as a turning point. “We are beginning to see more and more defections,” Pahlavi said, adding that “Either way, the regime is crumbling and is very close to collapsing.”

Over the past 24 hours, Iran International reported continued protests and strikes across the country, including in Tehran, Tabriz, Qazvin, Kermanshah, Kerman, Shiraz, Falavarjan and Bandar Abbas. Tehran’s Grand Bazaar remained a focal point of unrest, with large crowds chanting against Iran’s leadership as authorities responded with tear gas and armed deployments.
Security operations expanded into sensitive civilian locations. Videos published by Iran International showed tear gas used near or inside Tehran’s Sina Hospital and the Plasco Shopping Center.

Casualty and arrest figures continued to rise. The Human Rights Activists News Agency, cited by Iran International on Wednesday, reported at least 36 people killed since protests began, including 34 protesters and two members of Iran’s security forces, with more than 2,000 arrests nationwide. Iranian authorities have not released updated official figures.
New footage from the past day showed demonstrators lighting fires in the streets of Shiraz and chanting “Death to Khamenei,” referring to Supreme Leader Ali Khamenei. In Qazvin, protesters were heard chanting, “Law enforcement, return to the side of the nation.”

How Ukraine is shaping Europe’s response to Trump’s Greenland threats
For the past year, staying in Donald Trump’s good graces has become a top priority for European leaders, who have gone the extra mile to appease the mercurial US president, rein in his most radical impulses and keep him firmly engaged in what is their be-all and end-all: Russia’s war on Ukraine.
Though Europe is by far the largest donor to Kyiv, nobody on the continent is under the illusion that the invasion can be resisted without US-made weapons and come to an eventual end without Washington at the negotiating table.
In practice, the strategic calculus has translated into painful sacrifices, most notably the punitive tariffs that Trump forced Europeans to endure.
“It’s not only about the trade. It’s about security. It is about Ukraine. It is about current geopolitical volatility,” Maroš Šefčovič, the European Commissioner for Trade, said in June as he defended the trade deal that imposed a sweeping 15% tariff on EU goods.
The same thinking is now being replicated in the saga over Greenland’s future.
As the White House ramps up its threats to seize the vast semi-autonomous island, including, if necessary, by military force, Europeans are walking an impossibly thin line between their moral imperative to defend Denmark’s territorial integrity and their deep-rooted fear of risking Trump’s wrath.
The precarity of the situation was laid bare at this week’s meeting of the “Coalition of the Willing” in Paris, which French President Emmanuel Macron convened to advance the work on security guarantees for Ukraine.
The high-profile gathering was notable because of the first-ever in-person participation of Steve Witkoff and Jared Kushner, the chief negotiators appointed by Trump.
At the end of the meeting, Macron hailed the “operational convergence” achieved between Europe and the US regarding peace in Ukraine. By his side, British Prime Minister Keir Starmer was equally sanguine, speaking of “excellent progress”.
But it did not take long for the elephant in the room to make an appearance.
Hard pivot
The first journalist who took the floor asked Macron whether Europe could “still trust” America in light of the threats against Greenland. In response, the French president quickly highlighted the US’s participation in the security guarantees.
“I have no reason to doubt the sincerity of that commitment,” Macron said. “As a signatory of the UN charter and a member of NATO, the United States is here as an ally of Europe, and it is, as such, that it has worked alongside us in recent weeks.”
Starmer was also put on the spot when a reporter asked him about the value of drafting security guarantees for a country at war “on the very day” that Washington was openly talking about seizing land from a political ally.
Like Macron, Starmer chose to look at the bright side of things.
“The relationship between the UK and the US is one of our closest relationships, particularly on issues of defence, security and intelligence,” the British premier said. “And we work with the US 24/7 on those issues.”
Starmer briefly referred to a statement published earlier on Tuesday by the leaders of France, Germany, Italy, Poland, Spain, the UK and Denmark in defence of Greenland.
The statement obliquely reminded the US to uphold “the principles of sovereignty, territorial integrity and the inviolability of borders” enshrined in the UN Charter – precisely the same tenets that Moscow is violating at large in Ukraine.
The text did not contain any explicit condemnation of the goal to forcefully annex Greenland and did not spell out any potential European retaliation.
“Greenland belongs to its people. It is for Denmark and Greenland, and them only, to decide on matters concerning Denmark and Greenland,” its closing paragraph read.
Conspicuous silence
The lack of censure was reminiscent of the European response to the US operation that just a few days earlier removed Nicolás Maduro from power in Venezuela.
Besides Spain, which broke ranks to denounce the intervention as a blatant breach of international law, Europeans were conspicuously silent on legal matters. Rather than condemn, they focused on Venezuela’s democratic transition.
Privately, officials and diplomats concede that picking up a fight with Trump over Maduro’s removal, a hostile dictator, would have been counterproductive and irresponsible in the midst of the work to advance security guarantees for Ukraine.
The walking-on-eggs approach, however, is doomed to fail when it comes to Greenland, a territory that belongs to a member of both the EU and NATO.
Danish Prime Minister Mette Frederiksen has warned that the entire security architecture forged at the end of World War II, which allies have repeatedly invoked to stand up to the Kremlin’s neo-imperialism, would collapse overnight in the event of an annexation. The worry is that trying to stay in Trump’s good graces at all costs might come at an unthinkable price.
“Europeans are clearly in a ‘double-bind’: Since they are in desperate need of US support in Ukraine, their responses to US actions – whether on Venezuela or Trump threatening Denmark to annex Greenland – are weak or even muted,” said Markus Ziener, a senior fellow at the German Marshall Fund.
“Europeans are afraid that criticising Trump could provide a pretext for the US president to conclude a peace deal at Ukraine’s and Europe’s expense. Is this creating a credibility gap on the part of the EU? Of course. But confronted with a purely transactional US president, there seems to be no other way.”
