$This Webb image shows a pair of actively forming stars, known as Herbig-Haro 46/47, in high-resolution near-infrared light. To find them, trace the bright pink and red diffraction spikes until you hit the center. The stars are within the orange-white splotch. They are buried deeply in a disk of gas and dust that feeds their growth as they continue to gain mass. The disk is not visible, but its shadow can be seen in the two dark, conical regions surrounding the central stars. Image credit: NASA / ESA / CSA / Joseph DePasquale, STScI.$

This Hubble image shows Arp 263, an irregular galaxy located 27.1 million light-years away in the constellation of Leo. The color image of Arp 263 was made from separate exposures taken in the visible and near-infrared regions of the spectrum with Hubble’s Advanced Camera for Surveys and Wide Field Camera 3. Two filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.
