April 24, 2019: Current Projects and Initiatives This pair of open clusters lie about 7,000 light-years away from Earth. When we gaze that way, we’re looking toward the outskirts of the Milky Way Galaxy. It contains several blue stars, the brightest one of which is Mirfak, Alpha Persei, a white-yellow second magnitude giant. M34: M34 is an open cluster that may be seen (barely) with the naked eye and is easily resolved with a small telescope. Photo: ESO. The Alpha Persei Cluster is an open star cluster in Perseus. dark location without even featured, along with a brief explanation written by a professional astronomer. The Double Cluster is not included in Messier's catalog, but is included in the Caldwell catalogue of popular deep-sky objects. Also known as "h and chi Persei", this unusual double cluster, shown above, is bright enough to be seen from a dark location without even binoculars.Although their discovery surely predates recorded history, the … by orin stepanek » Wed Nov 18, 2020 8:16 pm, Post Also named Caldwell 14 or simply “The Double Cluster”, both star clusters are very similar to each other in size, magnitude, and age. 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 … Perseus is located in the Milky Way and covers an area of 615 square degrees. the clusters' ages The Double Cluster of Perseus. Just as zero is not equal to infinity, everything coming from nothing is illogical. binoculars. This means that the vehicle is in development but it is not yet ready to display in your Hangar or to drive in Star Citizen. (MTU) & by neufer » Wed Nov 18, 2020 1:44 pm, Post We invite you to contact us via email to the Perseus webmaster if you have any comments, questions, or concerns. by BDanielMayfield » Wed Nov 18, 2020 2:15 pm, Post Observation: South appears to be up in today's APOD, because when north is up, NGC 869 (the one without red giants) is to the right of NGC 884 (the one with the red giants. S Persei is a red supergiant or hypergiant star located near the Double Cluster in Perseus, situated at 7,900 light-years away from us. Open clusters NGC 869 and NGC 884, 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). The two brightest galaxies at the centre of this cluster are NGC1272 (right) and NGC1275 (left). APOD and General Astronomy Discussion Forum, Post Perseus’s borders contain a massive galaxy cluster, about 250 million light-years away. 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.

Greek astronomer Hipparchus cataloged the object (a patch of light in Perseus) as early as 130 BCE. It was quite impressive! The Perseus Galaxy Cluster This cluster contains about five hundred galaxies located approximately 250 million light years away towards the northern constellation of Perseus. by johnnydeep » Wed Nov 18, 2020 7:43 pm, Post It contains several blue stars, the … by BDanielMayfield » Wed Nov 18, 2020 6:12 pm, Post 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 … NGC 1275 is the dominant galaxy in the Perseus Cluster. This star has an apparent magnitude of 9.23, however, its brightness is very unpredictable, varying from 7.9 to 12.0, at chaotic rates. Credit: NASA/JPL-Caltech & Michigan Tech. NGC 1023: This is a barred spiral galaxy. The RSI Perseus is being offered for the first time as a limited vehicle concept pledge. Each of the Perseus clusters contains approximately 250 stars that are visible in 7-power binoculars. In addition to being Specific rights apply. This one is best in high quality (attach &fmt=18 to the URL). These two related star clusters belong to the best targets for small instruments. 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 … 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. their individual stars are similar - evidence that both 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. Although black holes cannot be seen directly, the smaller ones are at the center of some star clusters and supernova remnant nebulae, which can be seen. 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. double cluster, shown above, is bright enough to be seen from a The Perseus Cluster is one of the most massive objects in the Universe, and contains thousands of galaxies immersed in an enormous cloud of superheated gas. It is prominent from dark sites, having 16 stars of fourth magnitude or brighter. Perseus is the 24th largest constellation in the sky. It shows binary star clusters and the open star cluster M34. I have not done that many star clusters, but this is one of the most popular to image. Each day a different image or photograph of our fascinating universe is Abell 426: Abell 426 or the Perseus cluster is a massive group of thousands of galaxies.
