Merging event may have helped form the Milky Way
Today’s Video of the Day from the European Space Agency (ESA) shows a computer simulated merger between a galaxy similar to the Milky Way and a smaller galaxy.
The analysis of data from ESA’s Gaia mission suggests that this type of merging event occurred during the earliest formation of the Milky Way billions of years ago.
This computer animation is part of the ESA series Space in Videos.
