This image, taken by the Near-Infrared Camera (NIRCam) onboard the NASA/ESA/CSA James Webb Space Telescope, shows the star cluster NGC 346. Webb reveals the presence of many more building blocks than previously expected, not only for stars, but also planets, in the form of clouds packed with dust and hydrogen. The plumes and arcs of gas in this image contains two types of hydrogen. The pink gas represents energized hydrogen, which is typically as hot as around 10,000 degrees Celsius (approximately 18,000 degrees Fahrenheit) or more, while the more orange gas represents dense, molecular hydrogen, which is much colder at around minus 200 degrees Celsius or less (approximately minus 300 degrees Fahrenheit), and associated dust. The colder gas provides an excellent environment for stars to form, and, as they do, they change the environment around them. The effect of this is seen in the various ridges throughout, which are created as the light of these young stars breaks down the dense clouds. The many pillars of glowing gas show the effects of this stellar erosion throughout the region. In this image blue was assigned to the wavelength of 2.0 microns (F200W), green was assigned to 2.77 microns (F277W), orange was assigned to 3.35 microns (F335M), and red was assigned to 4.44 microns (F444W).

These Hubble images show two massive galaxy clusters: MOO J1014+0038 (left) and SPT-CL J2106-5844 (right). The artificially added blue color is translated from Hubble data that captured a phenomenon called intracluster light. This extremely faint glow traces a smooth distribution of light from wandering stars scattered across the cluster. Billions of years ago the stars were shed from their parent galaxies and now drift through intergalactic space.

This Hubble image shows the globular cluster NGC 1850, which is located in the Large Magellanic Cloud, over 160,000 light-years from Earth. For this image, five filters were used with the camera to gather data. Two of the filters were at near-ultraviolet wavelengths, two more at visible light wavelengths, and the final one was in the near-infrared. The data gathered through the two ultraviolet filters is violet and blue. The data from the two visible light filters is green and orange. The color red denotes near-infrared data. The image follows chromatic order, which means the shortest wavelength in the image is blue while the longest wavelength is red. Chromatic order allows us to visualize wavelengths of light beyond our eye’s sensitivity in a way that is familiar to us. Image credit: NASA / ESA / N.
