Well, this actually IS huge...
Fantastic!  Astronomers announce the discovery of the largest structure ever found in the entire known Universe!

Ring of 5 Gamma Ray Bursts 5 billions Light Years in diameter!  They all appear to be at about the same distance of 7 billions light years from us.

Prof Balazs comments: "If we are right, this structure contradicts the current models of the universe. It was a huge surprise to find something this big – and we still don't quite understand how it came to exist at all."

More on Gamma Ray Bursts: https://en.wikipedia.org/wiki/Gamma-ray_burst

"A Hungarian-US team of astronomers have found what appears to be the largest feature in the observable universe: a ring of nine gamma ray bursts – and hence galaxies - 5 billion light years across. The scientists, led by Prof Lajos Balazs of Konkoly Observatory in Budapest, report their work in a paper in Monthly Notices of the Royal Astronomical Society.

Gamma-ray bursts (GRBs) are the most luminous events in the universe, releasing as much energy in a few seconds as the Sun does over its 10 billion year lifetime. They are thought to be the result of massive stars collapsing into black holes. Their huge luminosity helps astronomers to map out the location of distant galaxies, something the team exploited.

The GRBs that make up the newly discovered ring were observed using a variety of space- and ground-based observatories (the sample is listed in the Gamma Ray Burst Online Index). They appear to be at very similar distances from us – around 7 billion light years – in a circle 36° across on the sky, or more than 70 times the diameter of the Full Moon. This implies that the ring is more than 5 billion light years across, and according to Prof Balazs there is only a 1 in 20,000 probability of the GRBs being in this distribution by chance.

Most current models indicate that the structure of the cosmos is uniform on the largest scales. This 'Cosmological Principle' is backed up by observations of the early universe and its microwave background signature, seen by the WMAP and Planck satellites. Other recent results and this new discovery challenge the principle, which sets a theoretical limit of 1.2 billion light years for the largest structures. The newly discovered ring is almost five times as large.

"If the ring represents a real spatial structure, then it has to be seen nearly face-on because of the small variations of GRB distances around the object's centre. The ring could though instead be a projection of a sphere, where the GRBs all occurred within a 250 million year period, a short timescale compared with the age of the universe.""

Even after years, this is still fascinating...
"We’ve managed to zoom in by more than a factor of 10^200, or more than a googol squared, and we still find this same self-similarity, and the same remarkable, intricate structures. There are ideas that perhaps the Universe is self-similar like this, but if it is, there’s a finite limit: the largest observable scales are “only” 92 billion light years or so (from one edge of the observable Universe to the other), while the smallest theoretical scale, the Planck scale, is down at around 10^-35 meters. All told, this is just 62 orders of magnitude, which doesn’t even account for the fact that non-gravitational forces begin to play important roles on scales the size of galaxies and smaller."

Mandelbrot zooms now surpass the scale of the entire observable Universe, and show no signs of loss of complexity or detail as they do. Lose yourself in these visuals, or celebrate 4/20 a little early, as is your wont.
