CG 4 nebula
 The CG4 nebula in the constellation Puppis is sometimes nicknamed as “Gods hand”. But we believe the nebula shape would probably resemble a giant worm from desert planet Arrakis to all Sci-Fi fans (what's more, the worm just tries to swallow entire galaxy :).

Scientists call these nebulae “cometary globules”, because of gaseous cloud shapes resemble comets (only much, much greater), and similarly to comets, such nebulae are shaped by stellar wind. While shape of comets is created by regular stellar wind from our Sun, CG4 was probably formed by supernova explosion, as it points to the location of supernova remnant in the constellation Vela.

The deep and detailed image of this very faint object was acquired by the CielAustral group of astrophotographers (Laurent Bourgon, Jean-Claude Canonne, Nicolas Outters, Philippe Bernhard and Didier Chaplain) from their observatory located at Obstech - Observatorio El Sauce in Chile. Image was acquired using G4-16000 camera on 50cm CDK20 telescope. Total exposure time was almost 60hours.
