A Scorpius Sky Spectacular
Explanation: If Scorpius looked this good to the unaided eye, humans might remember it better.
Scorpius more typically appears as a few bright stars in a well-known but rarely pointed out
zodiacal constellation. To get a spectacular image like
this, though, one needs a good
camera, color
filters, and a
digital image processor. To bring out detail, the
featured image not only involved long duration exposures taken in several colors, but one exposure in a
very specific red color emitted by
hydrogen. The
resulting image shows many breathtaking features. Vertically across the image left is part of the
plane of our
Milky Way Galaxy. Visible there are vast clouds of bright stars and long filaments of dark
dust. Jutting out diagonally from the
Milky Way in the image center are dark dust bands known as the
Dark River. This river connects to several bright stars on the right that are part of
Scorpius' head and claws, and include the bright star
Antares. Above and right of Antares is an even brighter planet: Jupiter. Numerous red
emission nebulas and blue
reflection nebulas are visible throughout the image.
Scorpius appears prominently in southern skies after sunset during the middle of the year.
