Fighting Dragons of Ara ( NGC 6188 & NGC 6164) by Michael Sidonio
Awarded a Highly Commended (top 5) in the 2011 Royal Observatory Greenwich Astronomy Photographer of the Year
This vibrant image captures clouds of swirling purple, green, and orange gas and dust, artistically resembling 'fighting dragons.' These dynamic formations are shaped by the recent births of massive stars, far larger and brighter than our Sun.
Prominently in the lower left of the image, one such star is encased within two glowing shells of gas. Offering a glimpse into the chaotic environments of stellar nurseries where stars are born, this scene mirrors the likely birthplace of our Sun some 4.5 billion years ago.
What National Geographic say about this image?
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.
