The most common stars in the Milky Way by far are runty M-dwarfs — only half as big as the Sun but eight times as numerous. The angular diameters of many stars can be measured directly using stellar interferometry. Previously thought to be the most massive single star, but in 2005 it was realized to be a binary system. Other stars, star clusters and a cloud of hydrogen are found in the spiral-shaped extensions of the nucleus. Their collective light produces the glow of the Milky Way. Most people grow up believing that the sun has to be the biggest star in the solar system but this is not true. Older estimates give up to 1,900.
