The large spiral galaxy shown in the image is UGC 2885, which is about 8 times the size of our galaxy. The number of stars alone is around 1 trillion, which is about 10 times more than in our galaxy. UGC 2885 is considered an important target for studying how massive galaxies form. It also appears in the research of Vera Rubin, an American astronomer. Vera Rubin is the person who first convincingly demonstrated that dark matter is predominantly present in the universe by studying the rotation of spiral galaxies.
