Let’s zoom in to one of the largest spiral galaxies ever seen, UGC 2885. We look across 232 million light-years of space to see the full expanse of the galaxy, which is over two times the width of our Milky Way galaxy and contains at least 1 trillion stars. The galaxy has been nicknamed Rubin's galaxy, after the late astronomer Vera Rubin, who used the galaxy to look for invisible dark matter. The galaxy is embedded inside a vast halo of dark matter.
