NASA’s Hubble telescope helps scientists solve mystery of dead galaxies
Why did some galaxies from the early universe suddenly stop making stars? Astronomers look back in time to find out.

As mere mortals, we yearn to travel back in time — an obsession nourished by iconic contraptions such as Marty McFly’s car, Hermione Granger’s time turner and Doctor Who’s police box. Often forgotten, however, are the real-life astronomers who kind of already do it.
Recently, one such research team tapped time travel to solve a space mystery from billions of years ago using a unique combination of super sensitive telescopes: Why did some of the early universe’s galaxies strangely stop popping out stars and become inactive, or quiescent?
Galaxies are thought to be at the pinnacle of their star manufacturing potential at this moment in time, so it’s especially puzzling when we discover any that are dormant. Right now, they should be making more stars than ever.
«The most massive galaxies in our universe formed incredibly early, just after the Big Bang happened,» Kate Whitaker, a professor of astronomy at University of Massachusetts-Amherst and lead author of a new study, said in a statement. «But for some reason, they have shut down. They’re no longer forming new stars.»
It turns out, some old galaxies merely ran low on star fuel, or cold gas, early on in their lifetimes. The results of the group’s study were published Wednesday in the journal Nature and could rewrite our knowledge of how the universe evolved.
But hold on, you’re probably still on that bit about astronomers going back in time. If they can swing that, why didn’t they show up to Stephen Hawking’s famous time-traveler-only dinner party?
You might have heard the term «light-year,» which refers to the distance light whizzes along in one Earth year. We need this term as a measurement because light doesn’t travel instantaneously. Of course, turning on your bedroom lamp leads to near-immediate brightness, but if someone turned on a flashlight while standing on the moon, about 238,900 miles (384,472 kilometers) away, its beam wouldn’t reach us for over a second.
That means moonlight has about a one-second lag for us Earthlings. In effect, when we glance at the moon, we’re seeing everything one second after it happens. We’re sort of looking back in time.
Astronomers scale that concept up by the billions. Using powerful telescopes as time machines, they look into deep space — like, billions of light-years away. For this study that mined the mystery of prematurely «dying» galaxies, for instance, the team looked at six cosmic bodies 10 billion to 12 billion light-years away in the universe.
So, it took 10 billion to 12 billion years for any illumination within the studied area to reach their telescope lenses. That means the astronomers were looking back in time far enough to watch the moments soon after the Big Bang — which occurred about 14 billion years ago — unfold in real-time.
Lo and behold, that’s how they solved the cosmic puzzle. The researchers say the galaxies either burned through their cold gas supply too quickly or are blocked from replenishment.
More specifically, Whitaker and fellow researchers demystified the issue by using a mixture of powerful telescopes: the Hubble Space Telescope and the Atacama Large Millimeter/submillimeter Array, or ALMA. The Hubble Space Telescope is sensitive to light across the spectrum — even the type humans can’t see.
And as if time travel wasn’t fantastical enough, the team took advantage of another tool called gravitational lensing to enhance the light collected. Basically, the lens’ viewpoint traveled along a line decorated by hundreds of other galaxy clusters.
Gravitational pulls of those galaxies were strong enough to warp beams of light coming from the team’s six galaxies of interest, stretching them while they traveled to Earth. That helped shed light — no pun intended — on juicy details that would have otherwise been missed within the galaxies.
ALMA, on the other hand, used those details to look for levels of the cold gas, or star fuel, needed by galaxies to make stellar bodies. «There was copious cold gas in the early universe, so these galaxies, from 12 billion years ago, should have plenty left in the fuel tank,» Whitaker said.
Now we know — thanks to the closest we’ve come to time travel — those tanks have been empty.

Siri’s New Features May Include Adding Voice Controls to Apps
A feature Apple showed off last year is reportedly being tested with popular third-party apps.

Apple is testing new features for its Siri assistant with popular apps — including Uber, Facebook and YouTube — that would make it possible to use third-party app features with voice commands, according to a report from Bloomberg.
The testing is being done with the goal of releasing a revamped Siri in the spring of 2026 that uses Apple’s App Intents to expand what Siri can do outside of Apple’s own OS and first-party apps. For instance, people might be able to post Instagram comments or make purchases using only their voice, something Siri can’t yet do with most apps that Apple didn’t develop itself, according to the report.
A representative for Apple did not immediately respond to a request for comment.
Apple showed off a demo of this type of functionality last year, but the overhaul might not arrive until 2027. According to Bloomberg’s Mark Gurman, there are some internal doubts among Apple engineers as to whether the functionality will work well enough, especially in apps where mistakes could be costly or harmful, such as health or banking apps.
Gurman points out that if the company gets it right, it would be a major feature that could give Apple, «a new, voice-first interface… it could potentially be a hit that many users didn’t see coming,» he writes.
Creeping competition
Even if Apple succeeds in revamping Siri with new features that customers find to be a big improvement, the company will be doing so under pressure from competitors on the artificial intelligence front.
«Apple should be worried, and it appears they are,» says Vikas Sharma, senior director of patent services at Quandary Peak Research. «ChatGPT, Gemini, Copilot and Alexa are all ahead of Siri in the AI race.»
Sharma expressed doubts that a spring 2026 release would include everything users might expect from a major Siri revamp. «At this point, there’s no update on any exciting upcoming capabilities, so the release may end up being incremental rather than revolutionary,» Sharma says.
But if Apple can work its magic and make good on some of the features that it gave a glimpse of last year, the effects could be profound.
«Imagine booking rides, flights, cars and hotels seamlessly through third-party apps; ordering from Amazon; sharing files through Slack/email; or finding emails with specific attachments, all through voice commands,» says Sharma. «With these capabilities, Siri could become a true AI assistant.’

ChatGPT’s New GPT-5 Model Is Supposed to Be Faster and Smarter. Not Everyone Is Satisfied
The new flagship engine behind OpenAI’s generative AI tool comes with a ton of changes.

ChatGPT’s long-awaited new engine is here, and GPT-5 promises faster speeds and more time spent thinking. But the new generative AI model has turned off some users with a tone shift away from its casual, conversational style.
GPT-5 has been in the works for months. It’s a big step for OpenAI, more than two years after the release of GPT-4, with the company touting the model as a giant leap for large language models. «I tried going back to GPT-4 and it was quite miserable,» said OpenAI CEO Sam Altman. «This is significantly better in obvious ways and subtle ways.»
Like its predecessor, GPT-5 powers the chatbots, agents, and search tools in ChatGPT and other apps that use OpenAI’s technology. Yet this version is supposed to be smarter, more accurate and faster.
Demonstrations showed GPT-5 quickly creating custom applications with no coding required, and developers said they’ve worked on ways to make sure it provides safer answers to potentially treacherous questions. (Disclosure: Ziff Davis, CNET’s parent company, in April filed a lawsuit against OpenAI, alleging it infringed Ziff Davis copyrights in training and operating its AI systems.)
One model for everybody (kinda)
The new model is available now, including those who use ChatGPT’s free tier. Unlike some of OpenAI’s incremental releases, GPT-5 will be rolled out for all users, not only to the companies paying for big enterprise plans.
There are, naturally, some differences between how it looks based on your pricing plan. Here’s a breakdown:
- Free users: You’ll get access to GPT-5 up to a usage cap, after which you’ll have a lighter GPT-5-mini model.
- Plus users: Similar to free users, but with higher usage limits.
- Pro users: Unlimited access to GPT-5 and access to a more powerful GPT-5 Pro model.
- Enterprise/EDU/Team users: GPT-5 will be the default model.
GPT-5 itself is really a couple of different models. There’s a fast but fairly straightforward LLM and a more robust reasoning model for handling more complex questions. A routing program identifies which model can best handle the prompt.
OpenAI originally replaced all its previous models with GPT-5, but users quickly rebelled. GPT-5, many said, was more stodgy and had less personality, sounding more corporate. After hearing that backlash on Reddit, Altman and OpenAI said they’d make older models like GPT-4o available again, at least for now.
Altman said in a post on X that some people have become attached to specific models and that it may be contributing to their use in potentially harmful ways, like therapy.
«If people are getting good advice, leveling up toward their own goals, and their life satisfaction is increasing over years, we will be proud of making something genuinely helpful, even if they use and rely on ChatGPT a lot,» Altman wrote. «If, on the other hand, users have a relationship with ChatGPT where they think they feel better after talking but they’re unknowingly nudged away from their longer term well-being (however they define it), that’s bad. It’s also bad, for example, if a user wants to use ChatGPT less and feels like they cannot.»
Even faster coding skills
OpenAI particularly highlighted the skills and speed at which the new GPT-5 model can write code, which isn’t just a function for programmers. The model’s ability to write a program makes it easier to solve the problem you present to it by creating the right tool.
Yann Dubois, a post-training lead at OpenAI, showed off the model’s coding ability by asking it to create an app for learning French. Within minutes, it had coded a web application complete with sound and working game functions. Dubois actually asked it to create two different apps, running the same prompt through the model twice.
The speed at which GPT-5 writes code allows you to try multiple times and pick the result you like best — or provide feedback to make changes until you get it right.
«The beauty is that you can iterate super quickly with GPT-5 to make the changes that you want,» Dubois said. «GPT-5 really opens a whole new world of vibe coding.»

New safety features
After announcing some steps to improve how its tools handle sensitive mental health issues, OpenAI said GPT-5 has some tweaks to make things safer. The new model has improved training to avoid deceptive or inaccurate information, which will also improve the user experience, said Alex Beutel, safety research lead.
It’ll also respond differently if you ask a prompt that could be dangerous. Previous models would refuse to answer a potentially harmful question, but GPT-5 will instead try to provide the best safe answer, Beutel said. This can help when a question is innocent (like a science student asking a chemistry question) but sounds more sinister (like someone trying to make a weapon).
«The model tries to give as helpful an answer as possible but within the constraints of feeling safe,» Beutel said.
Customized voices and colors
If you prefer to chat with your bots vocally rather than typing, expect improvements in voice capabilities. The Advanced Voice mode will now be available to all users, whether free or paid, and usage limits will be higher.
You can also change the color of your chats, with some options exclusive to paid users. Other customization options include the ability to tweak personalities. You’ll be able to set ChatGPT to be thoughtful and supportive, sarcastic or more. The options — Cynic, Robot, Listener and Nerd — are opt-in, and you can change them anytime.
Connect to your mail and calendar
ChatGPT will now be able to connect with your Google Calendar and Gmail accounts, meaning you can ask the chatbot about your schedule, and it will suggest things. You won’t have to — and you may not want to, depending on how you feel about sharing your private info — but you can enable it to automatically pull info from your mail or calendar without asking permission.
These connectors will start for Pro users soon, with other tiers gaining access thereafter.
The path to AGI?
Altman told reporters the model is a «significant step along the path to AGI,» or artificial general intelligence, a term that often refers to models that are as smart and capable as a human. But Altman also said it’s definitely not there yet. One big reason is that it’s still not learning continuously while it’s deployed.
OpenAI’s stated goal is to try to develop AGI (although Altman said he’s not a big fan of the term), and it’s got competition. Meta CEO Mark Zuckerberg has been recruiting top AI scientists with the goal of creating «superintelligence.»
Whether large language models are the way there, nobody knows right now. Three-quarters of AI experts surveyed earlier this year said they had doubts LLMs would scale up to create something of that level of intelligence.
