Description |
While
appearing close together in the
sky, the NGC 3576 and NGC 3603
nebulosities are at vastly
different distances, 3000
parsecs for the NGC 3576 group
and 8000 for NGC 3603.
This is well shown in colour
images with NGC 3603 appearing
much redder due to galactic
absorption. Click here
for a Hubble view of NGC 3603.
