Visualizing the Milky Way: A Stunning View of Our Galaxy.

TL;DR
Astronomers have been trying to determine the true morphology of the Milky Way for centuries. A team of researchers from the Chinese Academy of Sciences used the precise locations of very young objects in our galaxy to measure the morphology of the Milky Way. This revealed a multiple-arm morphology consisting of two symmetrical arms in the inner region and many irregular ones in the outer region. These findings could have drastic implications for our understanding of the Milky Way, and show that our galaxy is not an outlier but an example of a statistically significant astronomical object.
