RAPID STAR FORMATION ZONE: N79

This image from the James Webb Space Telescope shows N79, a massive star formation region within the Large Magellanic Cloud (a satellite galaxy of the Milky Way). At mid-infrared wavelengths, Webb reveals gas and dust glowing deep in the clouds, as well as embedded baby stars.

RAPID STAR FORMATION ZONE: N79

N79 is producing stars at a much faster rate than star-forming regions in our own galaxy. In fact, the chemical composition of N79 resembles that of the early universe, when star formation was at its peak.
Here, the vibrant rays that resemble sunlight are actually the diffraction spikes of a bright star. Diffraction spikes, which are most prominent for bright, compact objects, are somewhat like the "signature" of the telescope. The eight-dot pattern is the result of the telescope's hexagonal mirror design combined with secondary mirror supports. Meanwhile, our Hubble Space Telescope produces a four-pointed diffraction spike pattern due to its circular mirror.

Image description:

A bright young star in the upper left quadrant shines through layers of white and blue clouds on a dark background. The star is surrounded by thick orange spikes in an eight-pointed pattern that covers most of the frame. A patch of greenish-yellow clouds is visible in the upper right of the image. There are several bright spots seen as glowing yellow dots among the clouds, as well as another bright star with smaller blue diffraction spikes in the lower right corner.
