OBJECT DESCRIPTION AND IMAGE SESSION

 

Centaurus offers nearly all type of objects !! In this case we took the opportunity to spend some time collecting photons on this particularly nebula.

The whole structure is known as CG 12. In its head two bright reflection nebulas are visible: NGC 5367 and IC 4347. This Globule is located particularly high with respect the galactic plane; about 200 pc above.

 

Commentary Globules are dynamic structures formed by cold molecular clouds and hot ionized stars. Typically the head of the globule face intense radiation stars and boils lower density gas and intense stellar winds. The winds are formed from the ionized stars that evaporate dust and gas away from the head. (*)
