Known as the fighting dragons of Ara, two colorful gas clouds appear to be posing in attack position in a picture that received honorable mention in the “Deep Sky” category.

Australian astroimager Michael Sidonio captured subtle hues of purple, orange, and green from the giant cloud of gas and dust, which sits 4,000 light-years from Earth in the southern constellation of Ara.

The 300-light-year-wide molecular cloud is being shaped by radiation from massive young stars formed inside during the past few million years.
