The early universe was awash in dwarf galaxies that eventually combined to build up the stunning spiral galaxies around us today. Credit: NASAHubble Space Telescope Presents a Holiday Globe of StarsThe billion stars in galaxy UGC 8091 resemble a gleaming snow world in this festive Hubble Space Telescope image from NASA and ESA (European Space Agency). Instead, the stars that make up this celestial event look more like a vibrantly shining tangle of string lights than a galaxy.Some irregular galaxies may have ended up being tangled by tumultuous internal activity, while others have formed by interactions with neighboring galaxies. Among other things, the observing programs included in this image looked for to investigate the function that overshadow galaxies many billions of years back had in re-heating the hydrogen that had actually cooled as the universe broadened after the Big Bang.Astronomers are likewise examining the composition of dwarf galaxies and their stars to discover the evolutionary links between these ancient galaxies and more modern-day galaxies like our own.The Hubble Space Telescope is a job of international cooperation in between NASA and ESA.
The early universe was awash in dwarf galaxies that ultimately combined to develop up the stunning spiral galaxies around us today. Instead, the stars that make up this celestial event look more like a brilliantly shining tangle of string lights than a galaxy.Some irregular galaxies might have ended up being twisted by troubled internal activity, while others have formed by interactions with surrounding galaxies. Amongst other things, the observing programs involved in this image sought to investigate the role that overshadow galaxies many billions of years ago had in re-heating the hydrogen that had cooled as the universe expanded after the Big Bang.Astronomers are likewise investigating the structure of dwarf galaxies and their stars to reveal the evolutionary links in between these ancient galaxies and more contemporary galaxies like our own.The Hubble Space Telescope is a task of international cooperation between NASA and ESA.
