The obvious questions
What is galactic archaeology?
Galactic archaeology is the study of the history and formation of galaxies, including the Milky Way, by analyzing the stars and other celestial bodies within them.
What is the Gaia-Sausage-Enceladus merger?
The Gaia-Sausage-Enceladus merger is a well-known event in the Milky Way's history where a smaller galaxy collided with and merged into the Milky Way around 10 billion years ago.
How do scientists determine the age of stars in the Milky Way?
Scientists use various methods, including analyzing the composition and movement of stars, to determine their age and origin.
The story so far
The Milky Way's current structure is the result of two massive collisions with smaller galaxies. This event brought a significant number of stars into the Milky Way from another galaxy.
This merger is well-documented in scientific literature and has been a subject of study for some time. The recent discovery of the earlier collision has added a new layer to our understanding of the Milky Way's formation.
According to Nature, evidence of this massive accretion event has been found, providing insights into the galaxy's early history. ABC News & Headlines and Space have also covered how these ancient collisions transformed the Milky Way into the massive galaxy it is today.
