The Milky Way gobbled up another galaxy billions of years ago, study says

CNN  

CNN — About 10 billion years ago, the Milky Way looked very different from the galaxy that now serves as a home to our solar system. Dwarf galaxies contain between 100 million and several billion stars; the Milky Way now houses between 200 billion and 400 billion stars. Researchers were able to use the space telescope to look back in time at the early stages of the Milky Way’s formation, taking exact measurements of its stars to understand distance, brightness and position. About 10 billion years ago, the two galaxies collided violently, and Gaia-Enceladus became part of the Milky Way.

The Hindu  

The story so far: The third dataset released by the European Space Agency’s star-mapping Gaia probe, covering almost 1.8 billion stars in the Milky Way galaxy, has revealed an unexpected phenomena called ‘starquakes’, which are similar to earthquake-like movements but on the surface of stars. The data has also revealed the largest chemical map of the entire Milky Way, showing …

Astronomers Find Relic From a Galaxy That Once Consumed a Smaller One

News 18  

Astronomers at the Netherlands Research School for Astronomy have found that a globular cluster NGC 2005, a spherical collection of stars tightly bound by gravity in the Large Magellanic Cloud, a smaller neighbouring galaxy to the Milky Way, is actually a relic of the merger of a smaller galaxy into the LMC. The globular cluster, which is located some 750 …

CNN — Our large galaxy, the Milky Way, is orbited by more than 50 other, smaller galaxies. The Large Magellanic Cloud will catastrophically collide with the Milky Way in 2 billion years, according to a study published January in the Monthly Notices of the Royal Astronomical Society. But the merger between the LMC and the Milky Way has begun, and …

Daily Mail  

The Milky Way is not flat, as previously thought, but warped and twisted in shape, according to the most detailed map ever constructed. The map showed that the galaxy's disk, far from flat, is significantly warped and varies in thickness from place to place, with increasing thickness measured further from the galactic center The new map was formulated using precise …
