The Emerald Firebird is famous its ineluctably green feathers, and for dancing tip-toe in south-west Carina.
The thumbnail sketch shows some additional features in the region of the firebird's breast. Vulcan's Anvil, the horizontal yellow feature, has been struck so hard that it has generated quarks, anti-quarks, a bat (sketched in blue), and various pieces of molten gold.
One of the earlier blows has released a small slice of lemon, seen isolated in the sky below the drips of gold.
To the left of the bird's long neck is a tiny, intriguing patch of violet lightning, of unknown nature, but perhaps similar to the one we previously found in the Gabriela Mistral nebula.
Please do not challenge the Firebird for having emerald plumage. It is in its Buddha-nature to be so, and it pecks very hard. In more detail, this is presumably another example of an early star-forming region, where there is enough gentle UV to cause H-alpha emission, but not much in the way of super-large, ultra-hot stars that would produce OIII emission. However, we do note NII emission (red) along the bird's head, neck, and breast, and in the tail feathers. SII (not shown) proved to be utterly negligible, making it more plausible that this is a very young star-forming region.
This quickie of NGC 3572
(Big one here) is to celebrate last night's clear sky.
Green: H-alpha; Blue: OIII; Red: NII. 2 hrs each in 1hr subs. Aspen CG16M on 20" PlaneWave CDK.
