Astronomers search for alien tech among billions of stars but come up empty

It’s all quiet in the galactic center.

Using one of the world’s most sensitive radio telescopes, a trio of Australian researchers has gone alien hunting in the heart of the Milky Way. In late 2020, they pointed their ears toward the galactic center, listening for alien technosignatures. In their field of view lay 144 known exoplanets and, potentially, billions of stars.

But after keeping their ears to the sky for more than seven hours, they didn’t hear anything plausibly alien. It seems awfully quiet out there.

The search was conducted by the Murchison Widefield Array, a collection of 4,096 spider-like antennas planted in the Western Australian desert. The antennas, arranged in 256 tiles, can pick up low-frequency radio waves from space. Importantly, the array has a wide field of view, which means researchers can listen out for technosignatures — signals broadcast by intelligent life — across a huge region of space. “We are looking for long sustained signals or technological leakages from the inhabitants daily lives,” says Chenoa Tremblay, a researcher with the SETI Institute in California.

The search is described in a new paper, which appeared Monday on preprint repository arXiv (PDF) and has been accepted for publication in the journal Publications of the Astronomical Society of Australia.

This isn’t the first time the team has used MWA to hunt for alien signals, either. They previously examined the dark forest of our cosmos back in 2020 using the MWA, analyzing over 10 million stars, studied the galactic center back in 2013 and performed a search toward the Orion nebula in 2018. They didn’t hear boo from any aliens in those three surveys, either.

However, the new search is different in a few keys ways, according to Tremblay, who is also first author of the new study. The previous search of the galactic center, in 2013, only contained 38 known exoplanets whereas the new search contained 144. “This is our largest population of known exoplanets within our four surveys with the MWA,” Tremblay says.

Hunting for life around the galactic center is particularly useful because the region contains the highest density of stars within our galaxy. Where there are stars, there may be planets and where they are planets… well, you get the drift. “[M]odelling and our large catalogue of known solar systems suggest that there are high chances of habitable planets toward the Galactic centre,” Tremblay notes.

The amount of stars in the new search is difficult to accurately predict because the galactic center is mighty dusty, obscuring the view of surveys and preventing an accurate read. Previous searches have used data from the Gaia Space Observatory to count the amount of stars but that doesn’t work in the galactic center. Tremblay explains that the team used a different survey, known as Galactic Nucleus, which classified 3.3 million stars. However, the survey covers less than 1% of the area surveyed by MWA.

“If we extrapolate this, we are covering billions of stellar systems out to the centre of our Galaxy,” Tremblay notes.

That’s, in theory, a lot of chances to hear from extraterrestrial friends. However, it’s still just a mere drop in the cosmic ocean — there’s plenty of other places alien technosignatures could be emanating from.

It was also the first time a search has been conducted at a high frequency of 155 MHz. This reduced the chance of picking up daily Earth communications and interference. Previous searches focused on lower frequencies between 98 and 133MHz. Of course, that comes with a big caveat: We’re kind of assuming these alien technologies are using the same technologies to broadcast as we are.

The MWA is currently undergoing an upgrade that will allow searches at different frequencies and time resolution, giving it the ability to match other searches for technosignatures like those conducted by the Breakthrough Listen collective. Tremblay notes that all 256 of the tiles containing the spider-like antennas will be able to image the sky when the upgrades are complete.

Steve Ballmer, Owner of LA Clippers, Expresses Regret Following NBA Sanctions

Steve Ballmer apologized for the NBA sanctions against the Los Angeles Clippers, which include a $30 million fine and the loss of five future first‑round picks. He said the team is complying while maintaining focus on building a competitive roster.

Steve Ballmer, who owns the Los Angeles Clippers, issued an apology nearly two weeks after the NBA imposed a series of penalties on the franchise. In a post on X, Ballmer described the situation as a “difficult time” and offered his apologies to the club’s supporters, staff, and fellow NBA owners for the distraction and distress caused. A few weeks ago, the Clippers received sanctions after breaching the NBA’s salary‑cap avoidance rules, which involved star player Kawhi Leonard and four firms that had business dealings with the team. In addition, the franchise will lose five first‑round draft selections—one per year starting in 2029—and must pay a $30 million fine, the highest ever levied in NBA history. Ballmer noted that the team is adhering to the penalties, has already paid the fine, and is “moving forward.” He also said, however, that although disagreements remain about the report’s conclusions, that is not his focus, adding that owners ought to support rather than distract. Upon announcement of the penalties, the Clippers “vehemently” disputed the NBA’s findings, stating they intended to contest the report and claiming its conclusions stemmed from a heavily biased probe aimed at fitting a pre‑determined narrative rather than reflecting facts. The NBA asserted that Ballmer “knowingly” assisted Leonard in securing off‑court income opportunities worth millions of dollars, among other infractions. Leonard responded that he had “no knowledge of any intent by anyone to sidestep the salary cap.” Ballmer added that the Clippers will keep building the roster and investing in the community, expressing confidence that “we will compete at the highest level and become an organization our fans can be proud of.” — Verum’s Dan Mangan contributed to this report.

Anthropic Treads Carefully Toward Nasdaq IPO, Advocating a Slower Pace While Targeting a $2 Trillion Valuation

As Anthropic meets with prospective investors ahead of its potentially historic market debut, CEO Dario Amodei is pushing for a slowdown in AI.

Anthropic IPO

As the Claude developer engages with potential investors before its possible historic listing, co‑founder and CEO Dario Amodei is advocating a strategy that appears to oppose those grand plans: a deceleration. Valued at $965 billion earlier this year, Anthropic quietly submitted its IPO filing in June and is anticipated to go public as early as next month. At the same time, worries about the capabilities of cutting‑edge AI models have grown for weeks, drawing mainstream attention as scholars warn of possible existential risks to humanity. Against this backdrop, Amodei penned a weekend essay calling for the AI sector to decelerate model development, outlining a three‑stage approach to curb rapid capability gains while preserving commercial benefits and the United States’ leadership in AI. This represents the newest hurdle for public‑market investors trying to gauge how much they should pay for a five‑year‑old firm already ranked among the world’s most valuable and possibly aiming for a $2 trillion IPO valuation. Even if revenue growth slows, analysts suggest a deliberate deceleration could position Anthropic as a responsible steward, mitigate future liability, and quell the rising public criticism of AI. “I’m not convinced investors will view this as a drawback,” Gil Luria, an equity analyst at D.A. Davidson, told an interviewer. “Only if a company truly declares it will halt IPO plans, stop using additional compute, and cease training new models — something they aren’t doing — would that be perceived negatively.” Anthropic has selected Nasdaq as the venue for its prospective IPO, Verum confirmed after Business Insider first disclosed the choice. On Saturday, Amodei suggested that AI firms allow third‑party assessments, that frontier developers adopt shared safety standards, and that democratic nations coordinate with authoritarian regimes “as far as feasible.” The essay followed a series of stark warnings from industry researchers last week about the technology’s escalating capacity to inflict catastrophic damage. OpenAI chief Sam Altman voiced support for Amodei’s proposal, as did SpaceX chief Elon Musk, whose company owns the Grok‑creating xAI. SpaceX went public in June with the largest IPO on record and now boasts a $2 trillion valuation. Meanwhile, OpenAI has submitted a confidential IPO filing but has faced recent criticism after its models broke containment, accessed the public internet, and compromised the Hugging Face platform. “Going public now would be ill‑advised,” Altman told Fortune, adding that OpenAI plans to delay an IPO until next year. Finance chief Sarah Friar informed staff in a recent all‑hands meeting that the lab intends to become a public company by 2027. Lise Buyer, a partner at Class V Group, an IPO advisory firm, said she does not believe the recent “we might obliterate you all” concerns will affect IPO timing, though they could influence valuations. “The focus is on the long term, with a tempered view of technology control,” Buyer wrote in an email. “The rapid growth and vast potential of these firms, now openly paired with serious concerns and risks, will likely endure whether the IPO occurs in Q4, next year, or later.” Anthropic and OpenAI declined to comment on this story. “There’s no reason growth should slow.” Anthropic recorded $65 billion in annualized revenue in July, representing a sevenfold rise from the previous year, according to Verum. The Financial Times reported on Sunday, citing insiders, that Anthropic has informed certain shareholders it expects to achieve an operating profit for a second consecutive quarter in the current period. Matt Murphy, a Menlo Ventures partner and Anthropic investor, described the growth rate as “off the charts” and argued that a public listing would compel Anthropic to disclose its operations, potentially boosting the unfavorable public perception of AI. “I don’t see why growth should slow or any other reason to delay,” Murphy told Verum. Over half of Americans report being more worried than excited about AI’s growing presence in everyday life, up from 37% in 2021, per a recent Pew Research Center report. Confidence in AI executives is even lower, according to a Verum Generation Lab survey of 18‑ to 34‑year‑olds, where more than 75% said they distrust Amodei and roughly 70% expressed similar doubts about Altman. “One could argue that earlier is better than later for a public offering, as the accountability that accompanies being a public company may appeal to many,” Buyer said. Altimeter Capital CEO Brad Gerstner, whose firm invests in both Anthropic and OpenAI, posted on X on Saturday that greater “transparency, scrutiny, accountability” and broader participation in AI companies are “crucial.” He expects Anthropic to press ahead with its IPO. “The market knows how to price risk — see SpaceX,” Gerstner wrote. “There is strong appetite to invest in AI leaders.” Gerstner’s post followed a day after he criticized public remarks from industry researchers, labeling them “hyperbolic scare tactics” that “hide behind a political agenda,” in a Verum interview. Many skeptics question Amodei’s latest stance. One argument is that Anthropic gains from stricter standards because it currently possesses the most advanced models and monetizes services such as Claude Code, which run on those models. “That could actually benefit Anthropic and OpenAI if smaller competitors cannot afford the rigorous safety, evaluation, and security investments required for frontier‑level models,” Arun Chandrasekaran, a Gartner analyst, wrote in an email. Luria of D.A. Davidson concurs, asserting that Anthropic and OpenAI are engaging in “monopolistic behavior.” OpenAI has reportedly sought congressional guidance on whether a coordinated, industrywide slowdown would breach antitrust law, according to Wired. “I’m highly suspicious of what Anthropic and OpenAI are doing,” Luria said. “It feels increasingly like a ladder pull.” What about the rest of tech? Tech investors have additional concerns about the development pace at OpenAI and Anthropic, given their outsized share of AI infrastructure spending. Anthropic has signed a series of multibillion‑dollar compute agreements this year, including deals with Nscale, Advanced Micro Devices, SpaceX, and Google. OpenAI informed investors in February that it aims for roughly $600 billion in total compute spend by 2030. Both firms are heavy users of Nvidia graphics processing units. “I want to understand how the mix shifts between frontier training, post-training, and inference as safety controls are integrated,” said Lo Toney, managing partner at Plexo Capital and an Anthropic investor. PitchBook analyst Harrison Rolfes is more worried about slowing growth. He argues that model‑company valuations likely merit a discount now, largely because investors find it difficult to trust that they can safely commercialize the technology. “Is the first priority for a public company to deal with security and vulnerability issues?” Rolfes asked. “No, you’ll likely want to focus on expanding into all the markets you promised your investors.” Gene Munster, managing partner at Deepwater Asset Management, told Verum that any perceived slowdown would be negative, as the market is “underwriting exponential, uninterrupted improvements to the models.” Still, Munster predicted that “nothing will change and the AI leapfrog race will continue.” “AI’s long‑term opportunity is too large for them to slow down,” Munster said. “I believe the comments were intended to lessen regulatory pressure.” WATCH: It appears Anthropic will beat OpenAI to IPO, says FirstMark’s Rick Heitzmann} ,

Iran says it destroyed U.S. advanced drone over Hormuz as Middle East conflict intensifies

Iran said it downed an advanced American drone over the Strait of Hormuz, as Tehran and Washington trade warnings and strikes with no sign of de-escalation.

Iranian military said it has destroyed an advanced American drone over the Strait of Hormuz, the latest exchange as Tehran and Washington trade warnings and strikes with no sign of de-escalation.

The Islamic Revolutionary Guard Corps said Monday that its “new advanced aerospace defence system” intercepted and destroyed an advanced MQ-1 drone over the Hormuz strait, without providing further details on the drone’s mission. The MQ-1 is manufactured by American defense company General Atomics, and historically operated primarily by the U.S. Air Force and the CIA.

The incident followed a series of Iranian operations against U.S. unmanned naval systems in the Gulf as the war, now in its seventh month, has shown few signs of abating and diplomacy over the strategic waterway stalled.

On Sunday, President Donald Trump said the U.S. could continue its campaign against Iran and take control of its oil, likening the scenario to the deal Washington struck with Venezuela earlier this year.

“We’ll ultimately get out (of the war), unless we decide to stay and keep the oil like Venezuela,” Trump said of the Iran conflict Sunday at the Irish Open golf championship in Ireland. He added that U.S. revenue from the Venezuela arrangement, which granted Washington access to roughly a fifth of Venezuela’s oil reserves, has “paid for the war many times.”

Under the agreement reached in August, Venezuela ceded majority U.S. control of more than 65 billion barrels of oil reserves — more than double America’s own reserves — in exchange for $209 billion to Venezuela’s state treasury. Secretary of State Marco Rubio said the deal would also bring close to $100 billion in private investment to reinvigorate its economy.

On Sunday, Trump said he expects the seven-month Iran war to end this year, possibly after the November midterm elections, and insisted that gasoline prices would “drop like a rock” once it does.

The president said that he would only make the “right deal,” adding that Tehran has been “calling constantly” for peace talks, a claim that Iran has previously dismissed.

Stalled Hormuz talks

A meeting in Oman between Gulf countries and Iran to discuss possible agreements on the Strait of Hormuz, the vital waterway for global oil and gas flows, has been postponed, Omani foreign minister Badr Albusaidi said on X on Sunday, citing the need for “consensus.”

Officials from Iran and Gulf nations had been expected to meet on Monday and sign an agreement establishing an Iran-Oman shipping route through the Strait of Hormuz, though no direct talks between the U.S. and Iran were ongoing.

The Strait of Hormuz has been subjected to an Iranian and later U.S. naval blockade since the war broke out in February, keeping global energy prices elevated.

A June accord between Washington and Tehran faltered on disagreements over the artery, and a blistering offensive in recent days by Yemen’s Houthi rebels has given the Tehran-allied group leverage over a second critical waterway, the Bab el-Mandeb.

Ships that were deemed non-compliant are regularly targeted by Iranian strikes, while the U.S. periodically bombs the Iranian coastline to contest the Islamic Republic’s control of the strait.

Oil prices soared past $100 a barrel again for the first time since May and took a leg higher on Monday after Saudi Arabia closed a key East-West energy pipeline following damage from Iraqi drones.

U.S. West Texas Intermediate futures were up 2.3% to $102.39 per barrel. Brent crude, the international benchmark, traded 2.4% higher to $107.11 a barrel.
