A Look Into The Nursery
NGC 3324 in the Carina Nebula.
Captured in infrared light by NASA’s new James Webb Space Telescope, this image reveals for the first time previously invisible areas of star birth…
The tallest “peaks” in this image are about 7 light-years high. The cavernous area has been carved from the nebula by the intense ultraviolet radiation and stellar winds from extremely massive, hot, young stars located in the center of the bubble, above the area shown in this image…
Star birth propagates over time, triggered by the expansion of the eroding cavity. As the bright, ionized rim moves into the nebula, it slowly pushes into the gas and dust. If the rim encounters any unstable material, the increased pressure will trigger the material to collapse and form new stars.
Conversely, this type of disturbance may also prevent star formation as the star-making material is eroded away. This is a very delicate balance between sparking star formation and stopping it. What determines the number of stars that form in a certain region? Why do stars form with a certain mass?
Located roughly 7,600 light-years away, NGC 3324 was imaged by Webb’s Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI).
NIRCam – with its crisp resolution and unparalleled sensitivity – unveils hundreds of previously hidden stars, and even numerous background galaxies.
NGC 3324 was first catalogued by James Dunlop in 1826.

Question: How is birth given to a star? Answer: I do not know but I’m told the process is delicate.
