The Universe in Black and White

The universe in black and white

Contained within the most massive and active star-forming region in the Small Magellanic Cloud, star cluster NGC 346 delivers energetic radiation that excites nearby gas, causing it to glow. The result is one of the most dynamic and intricately detailed images of a nearby star-forming region that has ever been taken by the Hubble Space Telescope.

The complexity of the gas and dust that surrounds NGC 346 shows a series of arched, ragged filaments and a distinct ridge created when high-energy radiation from the young, hot stars eats into the denser areas of the nearby interstellar medium. The intricate, dark beaded edge of the ridge, seen from Hubble's perspective in silhouette, contains several small dust globules that point back towards the central cluster.

Energetic outflows and radiation from hot young stars are eroding the dense outer portions of the star-forming region, formally known as N66, exposing new stellar nurseries. The diffuse natal parts of the nebula block the energetic outflows from streaming away from the cluster, leaving a series of filaments marking the path of the outflows.

A close-up of a spiral galaxy, seen face-on. Its center is a bright white point, surrounded by a large yellowish oval with thin lines of dust swirling in it. From the sides of the oval emerge two bright spiral arms which wind through the round disk of the galaxy, filled with shining pink spots where stars are forming and more dark reddish dust. Many stars are visible in the foreground, over and around the galaxy.

The image is divided horizontally by an undulating line between a cloudscape forming a nebula along the bottom portion and a comparatively clear upper portion. Speckled across both portions is a starfield, showing innumerable stars of many sizes. The smallest of these are small, distant, and faint points of light. The largest of these appear larger, closer, brighter, and more fully resolved with 8-point diffraction spikes. The upper portion of the image is blueish, and has wispy translucent cloud-like streaks rising from the nebula below. The orangish cloudy formation in the bottom half varies in density and ranges from translucent to opaque. The stars vary in color, the majority of which have a blue or orange hue. The cloud-like structure of the nebula contains ridges, peaks, and valleys – an appearance very similar to a mountain range. Three long diffraction spikes from the top right edge of the image suggest the presence of a large star just out of view.
