Thank you Ann and Bruce. Alpha Persei Cluster (Melotte 20, Collinder 39) The Alpha Persei Cluster is an open star cluster in Perseus. & Michigan Tech. It also contains hundreds of stars … Perseus is located in the Milky Way and covers an area of 615 square degrees. 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. (MTU) & 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 … The Tarantula Nebula with large open cluster NGC 2070, at the center of which is compact massive cluster R136. Perseus, the celestial hero, stands well up in the east by mid-evening. Other bright members of the cluster include Delta, Epsilon, and Psi Persei. Just as zero is not equal to infinity, everything coming from nothing is illogical. M34: M34 is an open cluster that may be seen (barely) with the naked eye and is easily resolved with a small telescope. The Double Cluster in Perseus.

APOD and General Astronomy Discussion Forum, Post The clusters are over 7,000 light years distant toward the constellation of Perseus, but are separated by only hundreds of light years. The RSI Perseus is being offered for the first time as a limited vehicle concept pledge. 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.. 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. Perseus is a constellation in the northern sky, being named after the Greek mythological hero Perseus. The Double Cluster can be spotted in the middle of an imaginary line that links the Cassiopeia star Ruchbach, and the star Miram in the constellation of Perseus.

The number of stars jumps significantly when a telescope is used to view the individual clusters. constellation The estimated age of the cluster … U. NASA Web This pair of open clusters lie about 7,000 light-years away from Earth. clusters were likely a product of the same Optical observations with a 31 cm telescope are presented on photographic plates with attention to the double star configuration h-Perseus and Chi-Perseus. NGC 1275 consists of two galaxies. The picture (right) captures an area about 1.5 million light years wide. It contains several blue stars, the … Black Holes in Perseus. The star complex formed by the cluster family appears to be inclined ∼30° with respect to the plane of the Milky Way but is part of the Perseus arm. These two related star clusters belong to the best targets for small instruments. Privacy Policy and Important Notices. 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. Also known as "h and chi Persei", this unusual Perseus is a constellation in the northern sky, being named after the Greek mythological hero 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. The doublet is evaluated in terms of magnitude and color with help of the Hertzsprung-Russell diagram. The clusters are over 7,000 light years distant toward the constellation of Perseus, but are separated by only hundreds of light years. Also named Caldwell 14 or simply “The Double Cluster”, both star clusters are very similar to each other in size, magnitude, and age. The two brightest galaxies at the centre of this cluster are NGC1272 (right) and NGC1275 (left). 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. 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. The clusters are over 7,000 light years distant toward the In his hand he holds the head of Medusa, which is represented by the star Algol. The Double Cluster has been known since ancient times, but first catalogued only around 130 BC, when the Greek astronomer Hipparchos mentioned it as a “nebula” or “cloudy spot” in his writings.
