Spiral galaxy NGC 4414, Hubble Space Telescope image. New stars are being formed on the edges of the galaxy. These stars are blue, compared to the older stars in the centre. This is a flocculent spiral galaxy, meaning that the spiral arms are not well defined. The outer region is rich in clouds of interstellar dust. Due to the large size of this galaxy, it was photographed in sections by Hubble's Wide Field Planetary Camera 2 in 1995 and again in 1999, and a composite image was produced. Brightness measurements on some of the stars have revealed that the galaxy is about 60 million light years away from Earth.
