Our Milky Way Galaxy, which is commonly referred to as a regular massive spiral, is one of billions of such disc galaxies that occupy the observable universe.
According to a new research just submitted to The Astrophysical Journal, what is certain is that the Milky Way, and most likely many other galaxies like it, were huge enough to begin disc formation within a few billion years of the big bang. This is supported by fresh observations from NASA’s Webb Space Telescope.
Our findings show that the Milky Way gathered the majority of its mass early on, and that it thereafter experienced no important collisions with other galaxies that may have destroyed its disc.
