Scientists baffled by mysterious dusty object orbiting a star

They’re calling it a «unique object of uncertain nature.»

«What in the universe is that?» It’s a question that’s driven many science inquiries. When it comes to a «mysterious dusty object» discovered in observations from NASA’s Transiting Exoplanet Survey Satellite, the question remains open.

A team of astronomers is investigating something unusual happening around a binary star system called TIC 400799224, part of the TESS Input Catalog that logs objects seen by the NASA exoplanet-hunting mission. While TESS has confirmed over 170 exoplanets, it’s also caught sight of a lot of other objects, including TIC 400799224.

In a statement last week, the Harvard & Smithsonian Center for Astrophysics (CfA) said TIC 400799224 stood out during a computer analysis of TESS data due to «its rapid drop in brightness, by nearly 25% in just a few four hours, followed by several sharp brightness variations that could each be interpreted as an eclipse.»

TESS seeks out exoplanets by looking for telltale drops in brightness when a planet moves in front of a star. It takes follow-up work to confirm an exoplanet, and sometimes these dips in brightness indicate other things are going on.

The astronomers dug into previous observations of TIC 400799224 and found it’s likely a binary star system, like Tatooine in Star Wars. One of the stars is pulsating regularly, which could be caused by an orbiting object emitting dust that appears to dim the star. The dust clouds are irregular in size, shape and duration.

«The nature of the orbiting body itself is puzzling because the quantity of dust emitted is large; if it were produced by the disintegration of an object like the asteroid Ceres in our solar system, it would survive only about 8,000 years before disappearing,» CfA said. An analysis of six years of data on TIC 400799224 indicate the object is intact despite its odd outbursts.

The team published a paper on the dust-emitting object in The Astrophysical Journal in December, describing it as «a unique object of uncertain nature — but quite possibly a disintegrating asteroid or minor planet — orbiting one star of the widely separated binary TIC 400799224.»

There are still plenty of unknowns left to investigate, including which star in the system the object is orbiting and what kind of object is able to give off so much dust without falling apart. Said CfA, «The team plans to continue monitoring the object and to incorporate historical observations of the sky to try to determine its variations over many decades.»

While TESS may be focused on finding exoplanets, it has delivered plenty of bonus material, like this nifty look at a comet, a glorious view of the starry southern sky and, now, the intriguing mystery of TIC 400799224.

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.
