This cosmic structure is so huge that it is almost unimaginable. It is considered to be left behind following the Big Bang. The remnants of the Galaxy sit in the Milky Way’s backyard. The bubble is 1 billion light-years across, 10,000 times wider than the Milky Way. However, this giant bubble, invisible to the naked eye, is relatively close to our galaxy, regarding 820 million light-years away, and is what astronomers call the nearby universe. Daniel Pomarede, an astrophysicist at the French Atomic Energy Commission, told AFP that the bubble can be thought of as a “spherical shell with a center.” Inside the center is the Bootes supercluster. Surrounded by a vast void sometimes called the Great Void. This spherical shell contains several other superclusters known to science, including the massive structure known as the Sloan Great Wall. Pomerhead said the discovery of the bubble “is part of a very long scientific process.” The discovery was published this week in The Astrophysical Journal, of which Bomarhead is a co-author. The research confirmed the phenomenon first described in 1970 by American cosmologist Jim Peebles, who later became a Nobel Prize winner in physics. Piper theorized at the time that in the primordial universe (then composed of hot plasma), the agitation of gravity and radiation produced sound waves called Baryon Acoustic Oscillations (BAO), and as the sound waves passed through the plasma, they produced Bubbles out. Around 380,000 years following the Big Bang, this process stopped as the universe cooled, and the bubbles froze in shape. Later, as the universe expanded, the bubbles grew even larger, similar to other remnants of the Big Bang. This may be the first galactic bubble discovered, but many more may soon be discovered across the universe. The European Euclid Space Telescope was launched into space in July this year. It can conduct broad observations of the universe and may be able to capture more galaxy bubbles.
