Supernova Remnant S-147
Astrophotos | Home Page
|
Simeis 147, straddling the Auriga-Taurus border,
is a very old supernova remnant that has
expanded so much that it is barely visible.
This image (a full 6x7 frame) has been greatly
contrast enhanced to bring out the thin red
tendrils of the nebula to the point where they
are obvious. The diameter of the nebula is
about 3-1/2 degrees, or about 7 times the size
of the Moon.
The big blue halo around the nearby star is due
to the hazy sky condition. Open cluster M37 is
at the upper left of the frame.
