WebHá 5 minutos · Scientists said the galaxy, dating to 13.3 billion years ago, has a diameter of approximately 100 light-years – about 1,000 times smaller than the Milky Way – but forms new stars at a rate very similar to that of our much-larger present-day galaxy. A light-year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km). Web27 de jul. de 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). …
