NGC 1313

Three colour composite image of the barred spiral galaxy NGC1313 from the images at 4(blue), 4(green) and 15(red) micrometers. Stars are efficiently formed especially in the bright spiral arm regions in this galaxy as well as at the edge of the galaxy. It is speculated that such star formation activities were triggered by an enormous explosion on the southern region of this galaxy sometime in the past.
