Abell 426: Abell 426 or the Perseus cluster is a massive group of thousands of galaxies. Jerry Bonnell (UMCP) Star cluster Messier 6. It is one of the 48 ancient constellations listed by the 2nd-century astronomer Ptolemy, and among the 88 modern constellations defined by the International Astronomical Union. The two clusters are both massive and very much alike. The number of stars jumps significantly when a telescope is used to view the individual clusters. In addition to being physically close together, the clusters' ages based on their individual stars are similar - evidence that both clusters were likely a product of the same star … Other bright members of the cluster include Delta, Epsilon, and Psi Persei. Star cluster Messier 7. So the conclusion I take from this is that this double (open) cluster in Perseus really is unique, in that the two separate clusters are about the same size and age, and are physically close to each other (not just optically). In addition to being physically close together, the clusters' ages based on their individual stars are similar - evidence that both clusters were likely a product of the same star-forming region. One night decades ago I came across the Double Cluster by accident while randomly scanning the sky with a pair of new binoculars. Alpha Persei Cluster (Melotte 20, Collinder 39) The Alpha Persei Cluster is an open star cluster in Perseus. This annotated image, Figure 2, of the Perseus Molecular Cloud, provided by NASA's Spitzer Space Telescope, shows the location of various star clusters, including NGC 1333. The Perseus cluster is also fairly close to the plane of the Milky Way, so a lot of the faintest points of light in this image are actually foreground stars … Robert Nemiroff This picture below shows the central part of the Perseus cluster. The double star cluster is easily observed with the use of a small telescope. It is prominent from dark sites, having 16 stars of fourth magnitude or brighter. their individual stars are similar - evidence that both Discover the cosmos! Located on the edge of the Perseus Constellation, the collection of gas and dust is about 1,000 light-years from Earth and about 500 light-years wide. How to spot Perseus.
