Southern Orion: From Belt to Witch


Explanation:

Do you recognize the belt of Orion in this image?

The familiar trio of stars,
visible to the unaided eye,
can be found across the upper left.

Otherwise, the southern part of the constellation Orion has taken
on a new look in
this unusually deep and wide view

First note that the lower left belt star,
Alnitak,
is the easternmost star in Orion's belt.

Left of Alnitak is the Flame Nebula,
with clouds of bright emission and dramatic dark dust lanes.

Directly below
Alnitak,
a close inspection will reveal the
Horsehead Nebula.

Farther right and below is the Orion Nebula,
M42,
itself visible to the unaided eye.

The brightest star in the frame, near the bottom right, is
Rigel.

A bright blue star, Rigel illuminates the ominously shaped dust patch known as the
Witch Head Nebula, visible as the
blue reflection nebula near the
lower right corner.

Finally, appearing as a vast red ring and encompassing the entire region, is
Barnard's Loop.

Humans
could see this entire menagerie, unaided, were their eyes
about 10,000 times more sensitive.
