The observable universe just got a whole lot bigger! Discover the groundbreaking finding that our universe contains at least TEN TIMES more galaxies than previously estimated, pushing the total to an astonishing 1 to 2 quadrillion galaxies and approximately 700 quadrillion stars! This monumental research, led by Christopher Conselice from the University of Nottingham, analyzed extensive deep-sky surveys from the Hubble Space Telescope and other observatories.<br /><br />Learn how astronomers found that the majority of these newly identified galaxies are relatively small and dim, comparable to the satellite galaxies orbiting our own Milky Way. Over cosmic history, these smaller galaxies gradually merged to form larger ones, a process of significant galaxy evolution that supports the top-down model of structure formation in the universe. This means the overall density of galaxies has drastically decreased over time due to mergers.<br /><br />An incredible 90% of the universe's galaxies remain unstudied, presenting immense potential for future discoveries. The upcoming James Webb Space Telescope (JWST) is expected to play a crucial role in exploring these ultra-faint galaxies, unlocking even more secrets of our cosmic history.<br /><br />#ObservableUniverse #Galaxies #HubbleSpaceTelescope #JamesWebbSpaceTelescope #JWST #CosmicHistory #GalaxyEvolution #Universe #Astronomy #SpaceDiscovery #DeepSkySurveys #ChristopherConselice #UniversityOfNottingham #MilkyWay #Stars #QuadrillionGalaxies #ScienceNews #SpaceExploration #Mergers #TopDownModel #UltraFaintGalaxies
