NGC 2397, pictured in this Hubble image, is a classic spiral galaxy with long prominent dust lanes along the edges of its arms, seen as dark patches and streaks silhouetted against the starlight. Hubble’s exquisite resolution allows the study of individual stars in nearby galaxies.
Located nearly 60 million light-years from Earth, NGC 2397 is typical of most spiral galaxies, with mostly older, yellow and red stars in its central portion, while star formation continues in the outer, bluer spiral arms. The brightest of these young, blue stars can be seen individually in this high-resolution view from Hubble’s Advanced Camera for Surveys.
