Astronomers used to think that it was just a “filament” of galaxies. Latest research proposes this structure is not just bigger but its apparent massive size has astronomers scratching their heads.
Hercules-Corona Borealis Great Wall a massive galactic superstructure. Dr. Jon Hakkila, an astrophysics professor at the College of Charleston in South Carolina and one of the astronomers who discovered the structure, told The Huffington Post “The Her-CrB GW is larger than the theoretical upper limit on how big universal structures can be. Thus, it is a conundrum: it shouldn’t exist but apparently does.”
Mysteries just like this are why astronomers observe the skies for a glimpse into the past, as they shed light not only on the initial years of our cosmos, but also more about our own galaxy, as well as our solar system, and ultimately, ourselves.
As astronomers are still charting the sky, there just may be something even bigger than the Hercules-Corona Borealis Great Wall in our universe. Hakkila said “The danger of finding the biggest, or most distant, or the oldest things in the universe is always that sooner or later someone is likely to come along and find something bigger, more distant, or older than the thing you found. So far we have not been upstaged, but it has only been about six months since we published.”
Hercules-Corona Borealis Great Wall or the Great GRB Wallare proposed names of a massive galactic superstructure in a region of the sky seen in the data set mapping of gamma-ray bursts (GRBs) that has been found to have an unusually higher concentration of similarly distanced GRBs than the expected average distribution.
It was discovered in early November 2013 by a team of American and Hungarian astronomers led by Istvan Horvath, Jon Hakkila and Zsolt Bagoly while analyzing data from the Swift Gamma-Ray Burst Mission, together with other data from ground-based telescopes. The term “Hercules–Corona Borealis Great Wall” was coined by a Filipino teenager from Marikina City after reading a Discovery News report three weeks after the structure’s discovery.
The term is misleading, since the clustering occupies a region much larger than the constellations Hercules and Corona Borealis. In fact, it covers the region from Boötes to as far as the Zodiac constellation Gemini. In addition, the clustering is somewhat roundish in shape, which is more likely a supercluster, in contrast to an elongated shape of a galaxy wall. Another name was proposed in a later paper, the Great GRB Wall.
