This video is a zoom into the Hubble Space Telescope infrared Ultra Deep Field, first taken in 2009. It is a very small patch of sky in the southern constellation Fornax. Several thousand galaxies at various distances fill Hubble's field of view. The zoom centers on the farthest identified galaxy in the field. The galaxy, called UDFj-39546284, looks extremely red because its light has been stretched by the expansion of the universe. The object's tight cluster of stars is a fraction the size of our Milky Way galaxy. It represents an early transformative phase in the evolution of galaxies.
