Summary
[edit]DescriptionCaldwell 14 (50495978738).jpg |
Visible to the naked eye from a dark location, Caldwell 14 is popularly known as the Double Cluster in Perseus. These two bright open clusters, also called NGC 869 and NGC 884, appear side by side, about halfway between the bright stars in the constellations Perseus and Cassiopeia. Located about 7,500 light-years away, the clusters contain hundreds of hot, young stars that cause them to shine with apparent magnitudes of 5.3 and 6.1 in our sky. To the naked eye, the two clusters look like one large hazy patch, but binoculars and telescopes neatly split the pair, providing beautiful views of this celestial treasure. The Double Cluster appears highest for Northern Hemisphere observers during the late fall or early winter. (Southern Hemisphere observers close to the equator should look for it in late spring or early summer.) This Hubble image, taken with the Wide Field and Planetary Camera 2, shows stars in NGC 884 (the more eastern member of the pair). Captured through a single visible-light filter and colored blue, the image was taken as a “parallel” observation — obtained while the telescope was using another one of its science instruments to target a nearby object.
