This new view shows a stellar nursery called NGC 3324. The intense ultraviolet radiation from several of NGC 3324's hot young stars causes the gas cloud to glow with rich colors and has carved out a cavity in the surrounding gas and dust.
NGC 3324 is located in the southern constellation of Carina (The Keel, part of Jason’s ship the Argo) 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 fueled a burst of star birth 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.
As with clouds in the Earth's sky, observers of nebulae can find likenesses within these cosmic clouds. One nickname for the NGC 3324 region is the Gabriela Mistral Nebula, after the Nobel Prize-winning Chilean poet. The edge of the wall of gas and dust at the right bears a strong resemblance to a human face in profile, with the "bump" in the center corresponding to a nose.
Stellar winds and intense radiation from these young stars have blown open a hollow in the surrounding gas and dust. This is most in evidence as the wall of material seen to the center right of this image. The ultraviolet radiation from the hot young stars knocks electrons out of hydrogen atoms, which are then recaptured, leading to a characteristic crimson-colored glow as the electrons cascade through the energy levels, showing the extent of the local diffuse gas. Other colors come from other elements, with the characteristic glow from doubly ionized oxygen making the central parts appear greenish-yellow.
The image was taken using the Wide Field Imager on the MPG/ESO 2.2-metre telescope at the La Silla Observatory in Chile.
