NGC 1559
Galaxy in the constellation Reticulum
NGC 1559 is a barred spiral galaxy in the constellation Reticulum. It is also a Seyfert galaxy. Although it was originally thought to be a member of the Dorado Group,[2] 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.[3][4] NGC 1559 has massive spiral arms and strong star formation.[3] It contains a small bar which is oriented nearly east-west and spans 40″.[3] Its bar and disc are the source of very strong radio emissions.[3]
Four supernovae have been observed in NGC 1559. Australian amateur astronomer Robert Evans[5] discovered the first three: SN 1984J (type II, mag. 13.5),[6] SN 1986L (type II, mag. 13.5),[7] and SN 2005df (Type Ia, mag 12.3).[8] SN 2009ib (type IIP, mag. 14.7)[9] was discovered on 6 August 2009.
