NASA’s Hubble Captures Breathtaking Image of Intergalactic Bridge
An ethereal connection between two distant galaxies looks like it belongs in an episode of Star Trek.
Between black holes devouring smallish stars and vacant space surrounding busy, bursting nebulas, caverns of darkness in our universe are often relieved by glimmers of light. Such poetic juxtaposition is starkly apparent in one of NASA’s latest Hubble Space Telescope images.
Last week, the agency released an ethereal view of galactic triplet Arp 248, also known as Wild’s Triplet for both the discoverer and the utterly extravagant nature of the spectacle itself. Behold.
In this impeccable photo, two of three galaxies can be seen in the foreground of space’s void, bleeding into each other like they’re made of over-hydrated watercolor paint and forming what I can only describe as an intergalactic bridge. A third, unconnected realm stands in the far ground, enshrouded by deceptively tiny sparkles that represent a cosmic lifetime of even more galaxies scattered across the universe.
What’s especially mind-numbing about this image is that from Hubble’s vantage point — in Earth’s orbit, some 200 million light-years away — the three galaxies are compact enough to fit on our computer screens.
In reality, these worlds are many (many) light-years wide, holding an incomprehensible amount of doppelgangers to our sun, exoplanets like our solar system’s eight, and moons akin to our glowing lunar companion.
They are miniature universes in themselves, existing on a scale simply unfathomable to the human mind yet available for us to download as desktop wallpapers.
It is, in fact, because of those hefty contents that the two massive spirals at the centerpiece of this image are linked by a luminous bridge in the first place. Both harness immensely strong gravitational forces and are therefore pulling on each other like they’re playing a gentle tug of war, accidentally creating what’s known as a tidal tail, or an elongated stream of stars and iridescent interstellar dust.
Tidal tails are usually the product of galaxies treading very close to one another while on a path toward merging into one huge galaxy. We’ve seen the breathtaking phenomena several times already — tidal tails are responsible for some adorable galaxy systems names, too.
«The Mice,» or NGC 4676, boasts merging galaxies about 300 million light-years away from Earth, and «The Tadpole,» or UGC 10214, contains a large galaxy in the process of shredding a smaller galaxy, another event type that resulted in an awesome tidal tail.
Even our Milky Way galaxy is currently on a collision course with Andromeda, meaning they may eventually generate some sort of intergalactic bridge too — but don’t worry.
The emptiness between stars and planets within galaxies is far greater than you might think.
When galaxies merge, it’s quite likely only a few actual collisions happen. Think about two large crowds entering a stadium, merging into one massive crowd. Most of the time, individuals wouldn’t literally bump into each other. They just settle near each other. Now imagine the same situation, except with about a light-year of space between every person.
Fasincatingly, the title «Arp» in Arp 248 comes from the surname of late astronomer Halton Arp, who, along with astronomer Barry Madore, created the Atlas of Peculiar Galaxies in 1966.
«Each collection contains a menagerie of spectacularly peculiar galaxies, including interacting galaxies such as Arp 248, as well as one- or three-armed spiral galaxies, galaxies with shell-like structures, and a variety of other space oddities,» NASA said of the atlas.
It’s a vast work filled with yet more examples of our wonderfully contrasted universe, an expanse built from the mind of a poet and condensed with the skill of a machine.

Google races to put Gemini at the center of Android before Apple’s AI reboot
Google is using its latest Android rollout to position Gemini as the AI layer across phones, Chrome, laptops and cars.
Google is using its latest Android rollout to make Gemini less of a chatbot and more of an operating layer across the phone, browser, car and laptop, just weeks before Apple is expected to show its own Gemini-powered Apple Intelligence reboot at WWDC.
Ahead of its Google I/O developer conference next week, the company previewed a number of Android updates, including AI-powered app automation, a smarter version of Chrome on Android, new tools for creators, a redesigned Android Auto experience, and a sweeping set of new security features.
Alphabet is counting on Gemini to help Google compete directly with OpenAI and Anthropic in the market for artificial intelligence models and services, while also serving as the AI backbone across its expansive portfolio of products, including Android. Meanwhile, Gemini is powering part of Apple’s new AI strategy, giving Google a role in the iPhone maker’s reset even as it races to prove its own version of personal AI on the phone is further along.
Sameer Samat, who oversees Google’s Android ecosystem, told CNBC that Google is rebuilding parts of Android around Gemini Intelligence to help users complete everyday tasks more easily.
“We’re transitioning from an operating system to an intelligence system,” he said.
As part of Tuesday’s announcements. Google said Gemini Intelligence will be able to move across apps, understand what’s on the screen and complete tasks that would normally require a user to jump between multiple services. That means Android is moving beyond the traditional assistant model, where users ask a question and get an answer, and acting more like an agent.
For instance, Google says Gemini can pull relevant information from Gmail, build shopping carts and book reservations. Samat gave the example of asking Gemini to look at the guest list for a barbecue, build a menu, add ingredients to an Instacart list and return for approval before checkout.
A big concern surrounding agentic AI involves software taking action on a user’s behalf without permissions. Samat said Gemini will come back to the user before completing a transaction, adding, “the human is always in the loop.”
Four months after announcing its Gemini deal with Google, Apple is under pressure to show a more capable version of Apple Intelligence, which has been a relative laggard on the market. Apple has long framed privacy, hardware integration and control of the user experience as its advantages.
Google’s Android push is designed to show it can bring AI deeper into the device experience while still giving users control over what Gemini can see, where it can act and when it needs confirmation.
The app automation features will roll out in waves, starting with the latest Samsung Galaxy and Google Pixel phones this summer, before expanding across more Android devices, including watches, cars, glasses and laptops later this year.
The company is also redesigning Android Auto around Gemini, turning the car into another major surface for its assistant. Android Auto is in more than 250 million cars, and Google says the new release includes its biggest maps update in a decade and Gemini-powered help with tasks like ordering dinner while driving.
Alphabet’s AI strategy has been embraced by Wall Street, which has pushed the company’s stock price up more than 140% in the past year, compared to Apple’s roughly 40% gain. Investors now want to see how Gemini can become more central to the products people use every day.

Waymo recalls 3,800 robotaxis after glitch allowed some vehicles to ‘drive into standing water’
Waymo issued a voluntary recall of about 3,800 of its robotaxis to fix software issues that could allow them to drive into flooded roadways.
Waymo is recalling about 3,800 robotaxis in the U.S. to fix software issues that could allow them to “drive onto a flooded roadway,” according to a letter on the National Highway Traffic Safety Administration’s website.
The voluntary recall is for Waymo vehicles that use the company’s fifth and sixth generation automated driving systems (or ADS), the U.S. auto safety regulator said in the letter posted Tuesday.
Waymo autonomous vehicles in Austin, Texas, were seen on camera driving onto a flooded street and stalling, requiring other drivers to navigate around them. It’s the latest example of a safety-related issue for the Alphabet-owned AV unit that’s rapidly bolstering its fleet of vehicles and entering new U.S. markets.
Waymo has drawn criticism for its vehicles failing to yield to school buses in Austin, and for the performance of its vehicles during widespread power outages in San Francisco in December, when robotaxis halted in traffic, causing gridlock.
The company said in a statement on Tuesday that it’s “identified an area of improvement regarding untraversable flooded lanes specific to higher-speed roadways,” and opted to file a “voluntary software recall” with the NHTSA.
“Waymo provides over half a million trips every week in some of the most challenging driving environments across the U.S., and safety is our primary priority,” the company said.
Waymo added that it’s working on “additional software safeguards” and has put “mitigations” in place, limiting where its robotaxis operate during extreme weather, so that they avoid “areas where flash flooding might occur” in periods of intense rain.

Qualcomm tumbles 13% as semiconductor stocks retreat from historic AI-fueled surge
Semiconductor equities reversed sharply after a broad AI-driven advance, with Qualcomm suffering its worst day since 2020 amid inflation concerns and rising oil prices.
Semiconductor stocks fell sharply on Tuesday, reversing course after an extensive rally that had expanded the artificial intelligence investment theme well past Nvidia and driven the industry to unprecedented levels.
Qualcomm plunged 13% and was on track for its steepest single-day decline since 2020. Intel shed 8%, while On Semiconductor and Skyworks Solutions each lost more than 6%. The iShares Semiconductor ETF, which benchmarks the overall sector, fell 5%.
The sell-off came after a key gauge of consumer prices came in above forecasts, and as conflict in Iran pushed crude oil higher—prompting investors to shift away from riskier assets.
The preceding advance had widened the AI opportunity set beyond longtime industry leader Nvidia, which for much of the past several years had largely carried the market to new peaks on its own.
Explosive appetite for central processing units, along with the graphics processing units that power large language models, has sent chipmakers to all-time highs.
Market participants are wagering that the shift from AI model training to autonomous agents will lift demand for additional AI hardware. Among the beneficiaries are memory chip producers, which are raising prices as supply remains tight.
Micron Technology slid 6%, and Sandisk cratered 8%. Sandisk’s stock has surged more than six times over since January.
