 In 2015, the Hubble Space Telescope captured the sharpest and most detailed image ever taken of the galaxy. It shows over 100 million stars and thousands of star clusters embedded in a section of the galaxy's disk, stretching across over 48,000 light years. It traces the galaxy from its central bulge on the left, where stars are densely packed together across lanes of stars and dust to the sparser outskirts of its outer disk on the right. Zooming into the boxed field, we see some foreground Milky Way stars in the line of sight to Andromeda, and a couple of distant spiral galaxies shining through Andromeda's disk. The large group of blue stars in the galaxy indicates star-forming regions in the spiral arms. While the dark silhouettes of obscured regions trace out complex dust structures. Underlying the entire galaxy is a smooth distribution of cooler red stars that trace Andromeda's evolution over billions of years. A large number of star clusters can be seen in this analysis of Andromeda. This 150 light years across view of AP-14 and others like it are helping astronomers interpret the light from more distant galaxies that have similar structure.
