NGC 3324: A Pocket of Star Formation
This new view shows a stellar nursery called NGC 3324, located in the southern constellation of Carina roughly 7500 light-years from Earth. It is on the northern outskirts of the chaotic environment of the Carina Nebula, which has been sculpted by many other pockets of star formation.
A rich deposit of gas and dust in the NGC 3324 region fuelled a burst of starbirth there several millions of years ago and led to the creation of several hefty and very hot stars that are prominent in the new picture. Stellar winds and intense radiation from these young stars have blown open a cavity in the surrounding gas and dust. This is most in evidence as the wall of material seen to the centre right of the image.
The ultraviolet radiation from the hot young stars knocks electrons out of hydrogen atoms, which are then recaptured, leading to a characteristic crimson-coloured glow as the electrons cascade through the energy levels, showing the extent of the local diffuse gas. Other colours come from other elements, with the characteristic glow from doubly ionised oxygen making the central parts appear greenish-yellow.
