In the very center, you will see V380 Orionis, notice the
faint dark line in this image. This a reflection nebula,
sometimes called the keyhole nebula for its shape. Astronomers
were at a loss to explain this and it was assumed that it was an
extremely dense pocket of gas. In 2009, using the Mayall and
Magellan telescopes, it was determined that it is not gas, but truly
empty space. Astronomers are still trying to figure it out.
We are very pleased that we were able to get the keyhole, while it may
not be as impressive as the others, we are very pleased with it.
