NASA’s Hubble captured a dreamy image of the Intergalactic Bridge

Between black holes devouring small stars and the empty space that encompasses bustling nebulae, the caverns of darkness of our universe are often free of the glimmer of light — a poetic juxtaposition that is clearly visible in one of the latest images from NASA’s Hubble Space Telescope.

Last week, the agency released an ethereal view of the galactic triplet Arp 248, also known as the Wild’s Triplet for both the discoverer and the extremely extravagant nature of the spectacle itself. Look.

Take a closer look at everything in this beautiful image of our electrified universe.

In this flawless photo, two of the three galaxies can be seen in the foreground of the void of space, bleeding into each other as if made of over-hydrated watercolor paint and forming what I can only describe as an intergalactic bridge. A third, unrelated realm stands in a distant land, shrouded in deceptively tiny sparks representing cosmic life from even more galaxies scattered across space.

What’s particularly troubling about this image is that from Hubble’s vantage point — in Earth’s orbit, about 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 across, holding an unfathomable amount of doppelgangers to our sun, exoplanets like our solar system’s eight, and moons similar to our bright lunar companion.

They are miniature universes in their own right, existing on a scale simply unfathomable to the human mind, yet available for us to download as desktop backgrounds.

In fact, it is because of that enormous content that the two massive spirals in the center of this image are connected by a luminous bridge in the first place. They both use extremely strong gravitational forces and therefore pull on each other as if playing a gentle tug-of-war, accidentally creating what is known as a tidal tail, or an elongated stream of stars and iridescent interstellar dust.

Tidal tails are usually the product of galaxies moving very close to each other on their way to merging into one giant galaxy. We’ve seen the breathtaking phenomenon several times before – tidal tails are also responsible for some wonderful names for galactic systems.

Mice,” or NGC 4676, boasts a merging galaxy about 300 million light-years from Earth, and “A tadpole,” or UGC 10214, contains a large galaxy in the process of destroying a smaller galaxy, another type of event that resulted in a fantastic tidal tail.

Even our Milky Way galaxy is currently at a collision course with Andromedawhich means they can eventually generate some kind of intergalactic bridge also — but don’t worry.

The space between stars and planets within galaxies is far bigger than you think.

When galaxies merge, it’s very likely only a few real collisions happen. Imagine two large crowds entering the stadium, merging into one huge crowd. In most cases, individuals would not literally collide with each other. They just settle near each other. Now imagine the same situation, except with about a light year of space between each person.

Fascinatingly, the title “Arp” in Arp 248 comes from the surname of the late astronomer Halton Arpwhich he co-created with astronomer Barry Madore Atlas of Strange Galaxies in 1966.

“Each collection contains a menagerie of spectacularly unusual galaxies, including interacting galaxies like Arp 248, as well as spiral galaxies with one or three arms, galaxies with shell-like structures, and a host of other cosmic oddities,” NASA said. atlas.

It is a vast work filled with more examples of our wonderfully juxtaposed universe, a vastness built by the mind of a poet and condensed by the skill of a machine.
