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.

Apple Reportedly Plans to Send Siri Engineers to AI Coding Bootcamp

The move comes just weeks before the company is expected to unveil a new Siri.

Apple plans to send dozens of Siri engineers to a multiweek AI coding bootcamp, The Information reported Wednesday. The move comes less than two months before the company is widely expected to unveil a new Siri experience as part of a broader AI reboot.

A group of fewer than 200 engineers will be sent to the bootcamp, leaving approximately 60 members of the core Siri development team behind to continue working on Siri, while another 60 will evaluate Siri’s performance, according to The Information. The outlet also reported that AI has grown in popularity in some Apple divisions, prompting some teams within the company to allocate large parts of their budgets to Claude Code.

Apple representatives didn’t immediately respond to a request for comment.

Siri, once a pioneer, has lagged behind its rivals in voice assistants. Apple had planned to roll out a smarter, AI-driven Siri in 2025 as part of its Apple Intelligence initiative, but executives delayed the launch until spring 2026, admitting the early version wasn’t reliable enough to ship.

For Apple, the move would mark another attempt to reset expectations around its AI strategy after repeated delays to its more advanced Siri ambitions. The news also comes as John Giannandrea, Apple’s former AI chief, is reportedly leaving the company this week after stepping down from that role in December.

The new Siri experience is expected to be introduced at Apple’s Worldwide Developers Conference on June 8 and would arrive as part of iOS 27, iPadOS 27 and MacOS 27 later this year, according to a Bloomberg report in March. The report says Apple is testing out a new Siri that would make the assistant feel more like a standalone AI chatbot — think ChatGPT or Claude — rather than the current built-in tool.

Google Will Pay $135M to Android Phone Owners. Learn Who’s Eligible and How to Get Paid

If you used an Android phone with cell service in the last nine years, you could be eligible for compensation.

For years, Google has been accused of harvesting data from Android phones without users’ consent. A California lawsuit was settled for $314 million last year, and another class action lawsuit recently reached a resolution that could mean payouts for another 100 million people.

While not admitting fault, Google reached a preliminary settlement in the class action lawsuit Taylor v. Google LLC in January, agreeing to pay $135 million, and the official settlement website for the lawsuit is now live.

The final approval hearing won’t occur until June 23, when the court will hear objections and consider whether Google’s settlement is fair. After that, the court will decide whether to approve the $135 million settlement.

In the meantime, if you qualify and want to be paid as part of the settlement, you can select your preferred payment method on the official website. There, you can find information on speaking at the June 23 court hearing and on how to exclude yourself or write to the court to object by May 29.

As part of the settlement, Google will update its Google Play terms of service to clarify that certain data transfers do occur passively even when you’re not using your Android device, and that cellular data may be relied upon when not connected to Wi-Fi. This can’t always be disabled, but users will be asked to consent to it when setting up their device.

Google will also fully stop collecting data when its «allow background data usage» option is toggled off.

Who can be part of the Google data settlement?

In order to join the Taylor v. Google LLC settlement, you must meet four qualifications:

Be a living, individual human being in the US.
Have used an Android mobile device with a cellular data plan.
Have used the aforementioned device at any time from Nov. 12, 2017, to the date when the settlement receives final approval.
You’re not a class member in the Csupo v. Google LLC lawsuit, which is similar but specifically for California residents.

The final approval hearing is on June 23, so you can add your payment method until then. The hearing’s date and time may change, and any updates will be posted on the settlement website.

If you choose to do nothing, you will still be issued a settlement payment, but you may not receive it if you don’t select a payment method.

How much could I get paid by Google?

It’s not currently known exactly how much each settlement class member will receive, but the cap is $100. Payments will be distributed after final court approval and after any appeals are resolved.

After all administrative, tax and attorney costs are paid, the settlement administrator will attempt to pay each member an equal amount. If any funds remain after payments are sent, and it’s economically feasible, they will be redistributed to members who were previously and successfully paid. If it’s not economically feasible, the funds will go to an organization approved by the court.
