Straight Shot: Hubble Investigates Galaxy with Nine Rings

Summary

Hubble’s high-resolution imagery allowed researchers to hone in on more of the Bullseye galaxy’s rings — and helped confirm which galaxy dove through its core.

 

Seabirds like the Northern Gannet plunge directly into the sea in pursuit of fish, sometimes from as high as 100 feet (30 meters). The birds’ spear-like bills and expertly tucked wings minimize splash upon impact, but water still ripples out in tiny waves.

 

Now, let’s switch to space — and swap the bird for a tiny galaxy and the ocean for a vast galaxy.

 

A tiny blue dwarf galaxy flew through the far more massive Bullseye galaxy 50 million years ago with similar effects, producing at least nine star-filled rings in its larger companion. In space, those “waves” ripple out differently. The gas, dust, and stars are pushed both inward and outward.

 

Seeing an effect like this in great detail is highly unusual. Both the Hubble Space Telescope and the W. M. Keck Observatory in Hawaii proved that the Bullseye galaxy has nine rings — six more than any other known galaxy. Plus, Hubble identified which galaxy dropped through the Bullseye’s core: The blue dwarf galaxy that now “sits” directly to its left.

At 1.3 Billion Light-Years Wide, Quipu Is Officially

The Biggest Thing in The Universe

06 February 2025 By Evan Gough, Universe Today

 

Astronomers have found the largest structure in the Universe so far, named Quipu after an Incan measuring system. It contains a shocking 200 quadrillion solar masses...

 

Quipu is the largest structure we've ever found in the Universe. It and the other four superstructures the researchers found contain 45 percent of the galaxy clusters, 30 percent of the galaxies, 25 percent of the matter, and occupy a volume fraction of 13 percent.

It's amazing! It takes 1.3 billion light years to cross from one extreme to the other. This is likely to affect the current understanding of the cosmic microwave background, which has been used as a measure in determining the age of the universe.
