How did the galaxy start
WebWe do detailed studies of stars in the solar neighbourhood. This establishes the local density of stars and the mix of masses they possess (called the stellar mass function). We compare that with the mass function of clusters of stars and note that to first order it appears invariant. WebGiant elliptical galaxies are thought to also be formed by the process of similar-sized galaxies colliding [see videos linked at the bottom of the page], disrupting each other, and merging. In fact, it is thought that nearly all massive galaxies have undergone at least one major merger since the Universe was 6 billion years old. Clumpy Galaxies +
