Using deep space surveys from the Hubble telescope, scientists believe they can estimate what our
home galaxy, the Milky Way, looked like in its early years of development.
As the Hubble peers into deep space, scientists can study galaxies through their stages of development. These stages of development are then compared to the Milky Way and scientists can hypothesize how our galaxy would have undergone these stages.
NASA reports that this research has revealed “the Milky Way likely began as faint, blue, low-mass object containing lots of gas.” It is also believed that the Milky Way was shaped more as a flat disk with a bulge before becoming the spiral shape that we see today.
