The Near Infrared Sky
Was this picture taken from outside our Galaxy?
No, it is a composite taken from
Earth orbit,
well inside our
Milky Way Galaxy.
In light just a little too red for human eyes to see -
"near
infrared"
electromagnetic radiation -
the disk and
center of our Galaxy stand out
giving an appearance likely similar to seeing
our Galaxy from the outside in visible light.
The
above COBE image was recently reprocessed
for higher resolution and
shows red stars and dust in our Galaxy
superposed against the faint glow of
many dim stars in distant galaxies.
Faintly visible as an S-shaped sash running
through the image center is
zodiacal light --
dust in our own
Solar System.
Compared to the
far-infrared sky, little
Galactic dust is visible.
The two smudges on the lower right are the
Large and
Small Magellanic Clouds
neighboring galaxies.
