Ginormous Bubble of Galaxies: A Fossil from the Big Bang
Astronomers in Hawaii have discovered a massive bubble of galaxies, named Ho'oleilana, located 820 million light-years from Earth and spanning a billion light-years in diameter. This bubble, considered a fossil-like remnant of the birth of the universe, is larger than theoretical expectations. It was found within the cosmic web of galaxies and is associated with 3D ripples in the early universe known as Baryon Acoustic Oscillations (BAO). The discovery could provide insights into galaxy evolution and the expansion rate of the universe.
