The image on the left shows the starburst galaxy M82, as captured by NASA’s Hubble Space Telescope in 2006. The small box at the galaxy’s core represents the portion observed by the NIRCam instrument on NASA’s James Webb Space Telescope. In the Webb image, the red filaments correspond to the polycyclic aromatic hydrocarbon emission, which traces the shape of the galactic wind.

In the Hubble image, different filters were used to capture light at various wavelengths, resulting in colors ranging from red to blue. For example, light at .814 microns appears red, .658 microns is red-orange, .555 microns is green, and .435 microns is blue. In contrast, the Webb image uses different filters to capture light at 3.35 microns (red), 2.50 microns (green), and 1.64 microns (blue).

The combination of images from both telescopes provides a more comprehensive view of M82, allowing scientists to study the galaxy in greater detail. Researchers can analyze the structure and composition of the galactic wind, as well as other features within the galaxy. This collaboration between NASA, ESA, CSA, STScI, and researchers like A. Bolatto from the University of Maryland showcases the power of combining data from different telescopes to enhance our understanding of the universe.
