NGC 1559
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, 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.〔 In 2005, a Type 1a supernova, (SN 2005df) was observed. Two other supernovae discovered in NGC 1559 were SN 1984J and SN 1986L. All three were discovered by Australian amateur astronomer Robert Evans.〔(【引用サイトリンク】url=http://revivals.arkangles.com/supernovadiscoveries.php ) http://www.webcitation.org/6QJUITxOO〕 ==References==
