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.
