Wylie et al. investigated the metallicity, age, and orbital anatomy of the inner Milky Way, specifically focusing on the outer bar region. This image shows a metallicity map of the inner Milky Way, based on orbital data calculated by Wylie et al. The red star marks the position of the Sun, while the white dashed lines mark different sight lines. The red contours show specific density levels to highlight important features: a bar in the middle with a ring-like structure around it.

This image shows NGC 5921, a barred spiral galaxy some 78 million light-years away in the constellation of Serpens. This picture was created from images taken with Hubble’s Wide Field Camera 3 (WFC3). One optical and two infrared filter were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / J. Walsh / R. Colombari.
