Fornax is located in the Southern Hemisphere and is best seen in December.

The Fornax Cluster, a cluster of galaxies in this constellation, is the second-closest galaxy cluster to Earth and is one of the largest radio sources in the sky. The cause of the radio signals is a supermassive black hole at the center of galaxy NGC 1316.

Fornax is also the location of the Hubble Ultra Deep Field. The HUDF is a small region of space that the Hubble Telescope focused on for an extended period of time due to the lack of galaxies in the near field in that part of the sky. A combination of data from 2003 to 2014 (a total of 814 orbits of viewing time by the telescope) resulted in an image containing around 10,000 galaxies.

Fornax was originally named and created by Nicolas Louis de Lacaille in the mid-1700s.
