Web14 de abr. de 2024 · 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). The Milky Way is one of the two largest galaxies in the Local Group (the other being the Andromeda Galaxy), although the size for its galactic disc and how much it defines the isophotal diameter is not well understood. It is estimated that the significant bulk of stars in the galaxy lies within the 26 kiloparsecs (80,000 light-years) diameter, and that the number of stars beyond the outermost disc dramatically reduces to a very low number, with respect to an extrapolation of th…
