History

Fornax was identified by Nicolas Louis de Lacaille in 1756. He originally called it Fornax Chemica ("chemical furnace"), representing a small solid fuel heater used for heating chemical experiments.

In Chinese astronomy, constellation Fornax is lied in The White Tiger of the West (西方白虎, Xī Fāng Bái Hǔ).[1]

Notable features

Fornax has been the target of investigations into the furthest reaches of the universe. The Hubble Ultra Deep Field is located within Fornax, and the Fornax Cluster, a small cluster of galaxies, lies primarily within Fornax. At a meeting of the Royal Astronomical Society in Britain, a team from University of Queensland described 40 unknown "dwarf" galaxies in this constellation; follow-up observations with the Hubble Space Telescope and the European Southern Observatory's Very Large Telescope revealed that ultra compact dwarfs are much smaller than previously known dwarf galaxies, about 120 light-years (37 pc) across (Hilker M. et. al., 2007).

NGC 1316 is a notably bright elliptical galaxy within the Fornax Cluster. The galaxy is also one of the brightest radio sources in the sky.

UDFy-38135539, a galaxy which was identified as the most distant object in the universe from Earth as of October 2010, is located in Fornax. It was detected using the Hubble UDF image.

HIP 13044 b is an exoplanet in the constellation, reported in November 2010, that was discovered to have originated outside of the galaxy.[2]
