Gas-rich galaxies display a wide range of structures and properties, but one thing they all seem to have are some newly formed stars. Images from the Survey for Ionization in Neutral Gas Galaxies (SINGG), an NOAO Survey Program, are designed to highlight areas of star formation in gas rich galaxies.

This image shows M83.

Gerhardt Meurer of The Johns Hopkins University, Baltimore, MD, is the Principal investigator for SINGG. For more information, see:

MPIfR Press Release 06/2006 (2), June 29, 2006

A new CO map of the Andromeda galaxy was made by a German-French research team of the Max-Planck-Institut für Radioastronomie (MPIfR) in Bonn and the Institut de Radioastronomie Millimétrique (IRAM) in Grenoble. The map shows the first detailed distribution of cold gas in a neighbouring galaxy, revealing the sites where new stars are born. The motions of this gas were also obtained. With more than 800 hours of telescope time this study is one of the most extensive observational projects in millimeter radio astronomy.

Cool .. :)
