PIX4568549: Open cluster NGC 6939 and galaxy NGC 6946 - Spiral galaxy NGC 6946 and open cluster NGC 6939 - The spiral galaxy NGC 6946 is located about 10 million years ago - light in Cephee. Many star formations are observed here. The cluster of stars NGC 6939, on the right, belongs to our galaxy. Spiral Galaxy NGC 6946 and Open Cluster NGC 6939 are located about 2 degrees southwest of Eta Cepheus. 6946 is a 9.7 magnitude spiral galaxy that was discovered by William Herschel on September 9, 1798 and is about 10 arc minutes in diameter. It is a relatively close galaxy at a distance of about 10 million light years, and was once suspected by Edwin Hubble of being a member of the Local Group of galaxies that includes the Milky Way, but today it is not believed to be a member. Because we are looking at it through the plane of our own galaxy, it is highly obscured by dust. NGC 6946 is sometimes called the Fireworks galaxy because of the number of supernovae that have been discovered there and the galaxy's prodigious rate of star formation. By contrast, open cluster NGC 6939, seen about 40 arc minutes northwest of NGC 6946, is located inside of our own galaxy at a distance of approximately 36 light years. It is just by coincidence that these two objects lie close to each other in the same line of sight / Bridgeman Images
PIX4568402: Open cluster M26 in the ECU of Sobieski - Open cluster M26 in Scutum - M26 (NGC 6694) is located about 5000 years - light from Earth and is about 90 million years old. M26 is an open cluster in the constellation Scutum. A fairly tight cluster, in this deep image it has to compete with a very populous background of Milky Way stars. It is about 5000 light - years away and around 90 million years old / Bridgeman Images
PIX4568454: Open cluster M11 in the ECU of Sobieski - M11 open cluster in Scutum - M11 (NGC 6705) is a cluster of about 3000 stars. Image obtained by Siding Spring Clusters of bright blue stars like M11 are found scattered among the spiral arms of the Milky Way and other galaxies like it. They are a clear sign that star formation is active, because such clusters are usually very young and short lived. The stars in M11 all formed from the same material and at about the same time, a few million years ago. In 100 million years or so, all the brightest stars in the group will have evolved into cool supergiants and exploded as supernovae, leaving behind large numbers of low mass, relatively faint stars whose lives will be much longer and whose end will be much less dramatic. Located in the constellation of Scutum, it is sometimes mistaken for a loose globular cluster. M11 is also called the “” Wild Duck Cluster”” because of it's resemblance to a flight of wild ducks when viewed in a telescope. M11, with an overall brightness of magnitude 5.8, contains as many as 500 stars ranging from 8th magnitude down to 14th magnitude / Bridgeman Images
PIX4568736: Open Cluster of Pleiades - The Pleiades star cluster - The Pleiades cluster is a cluster of about 500 young stars nees 150 million years ago. Visible in the constellation Taurus, this cluster is 440 years from the Earth. The Pleiades are a reflection nebula associated with a cluster of young stars. The cluster itself is a group of many hundreds of stars about 400 light years from Earth in the northern constellation of Taurus.Seven of the brightest stars are quite easy to see with the unaided eye.The nebulosity seen here is light reflected from the particles in a cloud of cold gas and dust into which the cluster has drifted. It appears blue because these tiny interstellar particles scatter blue light more efficiently than the longer wavelengths of red light and it is streaky because of the distribution of dust particles in space / Bridgeman Images
TEC4568793: The Los Angeles periphery with Mount Cahuenga in the background above Hollywood (California, USA). In the background, the Hollywood sign was a historic monument. Visible has miles from many points of Los Angeles, it is not accessible to the general public. Built in 1923, the letters are 23 metres high and at that time advertised a real estate program. / Bridgeman Images
PIX4568904: Hyad cluster - Mel 25 - The Hyades cluster in Taurus - Mel 25, the Hyades, is an open cluster visible to the naked eye in the constellation Taurus. The red giant star Aldebaran is the brightest star in the image. On the left, the small open cluster NGC 1647. The Hyades is a beautiful open cluster in Taurus that is easily visible to the unaided - eye. Brilliant Aldeberan, a 0.9 magnitude red giant star, dominates the cluster which is located about 153 light years away. Smaller open cluster NGC 1647 is on the left in the image, some 45 acr minutes in diameter at magnitude 6.4 / Bridgeman Images
