Because of the inability to conduct experiments in outer space, the only way to “test” theories and models of galaxy evolution is to compare them with observations. Explanations for how galaxies formed and evolved must be able to predict the observed properties and types of galaxies. Edwin Hubble created the first galaxy classification scheme known as the Hubble tuning-fork diagram. It partitioned galaxies into ellipticals, normal spirals, barred spirals (such as the Milky Way), … WebAstronomers compare star formation across galaxies to understand the differences. Observations provide a lot of information about star formation, but it’s a slow process by human standards. For that reason, researchers at the Institute for Theory and Computation at the Center for Astrophysics simulate the details of star formation on computers. Web27 jul. 2016 · 11. Yes, definitely. Galaxies grow through smooth accretion of matter (both dark and baryonic), and through mergers with other galaxies. Minor mergers (i.e. where one galaxy is much larger than the other) simply disrupt the smaller one without changing the shape of the larger (but may increase its star formation rate for a while). Major mergers ... birleywood health centre skem
