Is it a four-leaf clover in the space?
No, it is the Stingray Nebula (Hen 3-1357) locates in constellation Ara.
The image shows the actual colours of the nebula emitted by nitrogen (red), oxygen (green) and hydrogen (blue).
Happy St. Patrick's Day!
And my condolences to the Japanese and everyone lost their beloved ones.
