NGC 1559 is a barred spiral galaxy in the constellation Reticulum. It was discovered on 6 November 1826 by Scottish astronomer James Dunlop.[1]
NGC 1559 is a Seyfert galaxy, i.e. it has a quasar-like nuclei with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable. Although it was originally thought to be a member of the Dorado Group, subsequent observations have shown that it is in fact not a member of any galaxy group or cluster and does not have any nearby companions. NGC 1559 has massive spiral arms and strong star formation. It contains a small bar which is oriented nearly east-west and spans 40. Its bar and disc are the source of very strong radio emissions.
Four supernovae have been observed in NGC 1559. Australian amateur astronomer Robert Evans[2] discovered the first three: SN 1984J (type II, mag. 13.5),[3] SN 1986L (type II, mag. 13.5),[4] and SN 2005df (Type Ia, mag 12.3).[5] SN 2009ib (type IIP, mag. 14.7)[6] was discovered on 6 August 2009.
