NASA’s Hubble opens the earliest window into the young Milky Way
The Milky Way, spanning over 100,000 light-years, is our galactic home. Among its many discoveries, the ESA’s Gaia mission has found that the Milky Way galaxy not only has a warp to its galactic disk, but that the warp in the disk precesses and wobbles, completing a full rotation for roughly every three revolutions of the Sun (in yellow) around the galactic center. The origin of the Milky Way’s rotation is not cosmic, but rather is thought to a…
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.
Galactic archaeologists find stars in the Milky Way came from another galaxy 12 billion years ago
Sven Buder, Australian National University Look up on a dark night and the Milky Way appears as a calm band of stars across the sky. But our galaxy has a violent past. For more than 13 billion years it has grown through star formation and mergers with other galaxies. We already know that several substantial galaxies helped build the young Milky Way. A new study, published in Nature Astronomy, now brings one of the earliest of these events into …
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 …
