IRAS images of the Taurus - Perseus - Orion region

Here I have collected a few IRAS images of star forming regions I have studied. These images are so-called `true colour' images, in which the different colors correspond to different infrared wavelengths: the 12 micrometer radiation is shown in blue, 60 micrometer in green, and 100 micrometer in red.

The first image is a very large field of the sky (some 100 x 100 square-degrees) including the Perseus molecular cloud complex (upper right), the Taurus-Auriga molecular cloud complex (upper left), and the Orion star forming region (lower center).


The next image shows a 6 x 6 square-degree field centered on the Perseus molecular cloud complex. The green circles mark the two most important site of recent and ongoing star formation, IC 348 (left), and NGC 1333 (right). The green crosses mark the positions of X-ray sources detected by ROSAT.


The next image show the Orion star forming region. Here, the green circles with embedded asterisks mark the positions of the optically brightest stars.


Images of the Scorpius-Centaurus OB association can be found here.
