Alpha Persei Cluster (Melotte 20, Collinder 39) The Alpha Persei Cluster is an open star cluster in Perseus. The clusters are over 7,000 light years distant toward the constellation of Perseus, but are separated by only hundreds of light years. The clusters were likely formed in the same star forming cloud in the Perseus Arm of the Milky Way and both belong to the Perseus OB1 association, a group of extremely massive stars. Also named Caldwell 14 or simply “The Double Cluster”, both star clusters are very similar to each other in size, magnitude, and age. Trumpler 2 is an interesting open cluster due west of eta Pers - STF 307. The Alpha Persei Cluster is an open star cluster in Perseus. These two related star clusters belong to the best targets for small instruments. by Ann » Wed Nov 18, 2020 7:54 pm, Post The Spitzer image of the Perseus Molecular Cloud superposed on a much area of the sky in visible light, with constellations marked.

NASA Web Combining data from NASA's Chandra X-ray Observatory with radio observations and computer simulations, scientists have found a vast wave of hot gas in the Perseus galaxy cluster.Spanning some 200,000 light years, the wave is about twice the size of the Milky Way galaxy.. The Double Cluster in Perseus (NGC 869 and NGC 884) are two open clusters in the constellation Perseus. In terms of frequency (the time it takes a single sound wave to pass by), the lowest sounds a person can hear is 1/20th of a second. I feel like most people's comments on the images we get are so intelligent and/or clever and I'm like, "Oooh, pretty!".
