M83 Galaxy. Color images of this galaxy reveal a wide range of colors
from the yellow central core of old stars to the blue spiral arms of young
stars. Several red knots can also be seen These are gaseous nebulae where
active star formation is taking place. Dark lanes of dust are also visible
throughout the galaxy’s disk. The image shown on the next page was obtained
in February 2004 using the Prime Focus Camera on the William Herschel Telescope,
and it is a combination of filters Johnson B, V and R. Credit: Chris Benn

M74 Galaxy. Its arms are traced with clusters of blue young stars
and pinkish colored diffuse gaseous nebulae (HII regions), and reach out
to cover a region of roughly 95,000 light years, or about the same size as
our Milky Way galaxy. The image was obtained in August 2004 using the Wide
Field Camera on the Isaac Newton Telescope. The colour composite was built
from filters B, V and R and using Adobe Photoshop with the help of the ESA/ESO/NASA
Photoshop FITS Liberator plugin. Credit: Simon Dye (Cardiff University).
M81 Galaxy. The image is a combination of exposures obtained in 2003
