The Eta Carina Nebula is one
of the largest diffuse nebula
visible from earth, 4X bigger
than the great Orion Nebula,
but much less well known,
given its southern hemisphere
location. The so-called
Keyhole Nebula is visible
towards the center, as is Eta
Carina itself, a star which
briefly became the 2nd
brightest in our skies, after a
huge outburst in 1841.
