The Orion You Can Almost See
Explanation: Do you recognize this constellation? Although it is one of the
most recognizable star groupings on the sky,
this is a
more full Orion than you can see -- an Orion only revealed with long exposure digital camera imaging and
post-processing. Here the cool
red giant Betelgeuse takes on a strong orange tint as the brightest star at the lower left. Orion's hot blue stars are numerous, with
supergiant Rigel balancing Betelgeuse on the upper right, and
Bellatrix at the upper left. Lined up in
Orion's belt are three stars
all about 1,500
light-years away, born from the constellation's well-studied
interstellar clouds. To the right of Orion's belt is a bright but fuzzy patch that might also
look familiar -- the stellar nursery known as
Orion's Nebula. Finally, just barely visible to the
unaided eye but quite striking here is
Barnard's Loop -- a huge gaseous emission nebula surrounding Orion's Belt and Nebula discovered over 100 years ago by the pioneering Orion photographer
E. E. Barnard.
