The Milky Way, a vast spiral-shaped galaxy that houses hundreds of billions of stars, including our solar system, has gone a long and complicated way to reach the current dimensions, shows the results of a new research documenting a reference event in the early stages of its history. It's about the first fusion with a smaller galaxy in Milky Way history.
Hubble Finds the Milky Way’s Earliest Major Merger
Hubble observations of 39 globular clusters reveal evidence that the young Milky Way absorbed a dwarf galaxy about 11.8 billion years ago. The post Hubble Finds the Milky Way’s Earliest Major Merger in Ancient Star Clusters appeared first on Curiosmos.
The Milky Way suffered a galactic collision 12.3 billion years ago that shaped its primitive growth. The discovery, published in Nature Astronomy, reconstructs that shock from 39 globular clusters observed by the Hubble telescope and the ESA's Gaia mission. The Milky Way did not just manufacture its own stars. It also grew by devouring neighboring systems, a process that astronomers call galactic cannibalism. The new research adds an older episo…
Madrid. Galaxies such as the Milky Way are believed to be formed over billions of years through mergers with smaller systems. A team of astronomers has now succeeded in rebuilding the early evolutionary stages and mergers of our galaxy thanks to the "exquisite" data from the Hubble telescope. Specifically, they have discovered evidence of a fusion that took place about 11.8 billion years ago, just 2 billion years after the Big Bang. Details are …
