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.

Want to Speak to Dolphins? Researchers Won $100,000 AI Prize Studying Their Whistling

The scientists studied a bottlenose dolphin community in Sarasota, Florida, uncovering evidence of language-like communications.

If any dolphins are reading this: hello!

A team of scientists studying a community of Florida dolphins has been awarded the first $100,000 Coller Dolittle Challenge prize, set up to award research in interspecies communication algorithms.

The US-based team, led by Laela Sayigh of the Woods Hole Oceanographic Institution, found that a type of whistle that dolphins employ is used as an alarm. Another whistle they studied is used by dolphins to respond to unexpected or unfamiliar situations. The team used non-invasive hydrophones to perform the research, which provides evidence that dolphins may be using whistles like words, shared with multiple members of their communities.

Capturing the sounds is just the beginning. Researchers will use AI to continue deciphering the whistles to try to find more patterns.

«The main thing stopping us cracking the code of animal communication is a lack of data. Think of the 1 trillion words needed to train a large language model like ChatGPT. We don’t have anything like this for other animals,» said Jonathan Birch, a professor at the London School of Economics and Politics and one of the judges for the prize.

«That’s why we need programs like the Sarasota Dolphin Research Program, which has built up an extraordinary library of dolphin whistles over 40 years. The cumulative result of all that work is that Laela Sayigh and her team can now use deep learning to analyse the whistles and perhaps, one day, crack the code,» he said.

The award was part of a ceremony honoring the work of four teams from across the world. In addition to the dolphin project, researchers studied ways in which nightingales, marmoset monkeys and cuttlefish communicate.

The challenge is a collaboration between the Jeremy Coller Foundation and Tel Aviv University. Submissions for next year open up in August.

Dolphins are just the beginning

Researching animals and trying to learn the secrets of their communication is nothing new; but AI is speeding up the creation of larger and lager datasets.

«Breakthroughs are inevitable,» says Kate Zacarian, CEO and co-founder of Earth Species Project, a California-based nonprofit that also works in breaking down language barriers with the animal world.

«Just as AI has revolutionized the fields of medicine and material science, we see a similar opportunity to bring those advances to the study of animal communication and empower researchers in this space with entirely new capabilities,» Zacarian said.

Zacarian applauded Sayigh’s team and their win and said it will help bring broader recognition to the study of non-human animal communication. It could also bring more attention to ways that AI can change the nature of this type of research.
«The AI systems aren’t just faster — they allow for entirely new types of inquiry,» she said. «We’re moving from decoding isolated signals to exploring communication as a rich, dynamic, and structure phenomenon — whish is a task that’s simply too big for our human brains, but possible for large-scale AI models.»

Earth Species recently released an open-source large audio language model for analyzing animal sounds called NatureLM-audio. The organization is currently working with biologists and ethologists to study species including carrion crows, orcas, jumping spiders and others and plans to release some of their findings later this year, Zacarian said.
