PIX4568850: 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 one of the finest and nearest examples of 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 and has been recognised since ancient times. Seven of the brightest stars are quite easy to see with the unaided eye and bear the names of the Seven Sisters, the daughters of Atlas. 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
PIX4565630: Galaxy clusters 1ES 0657 - 55 in the Carene - Gravitational lens in galaxy cluster 1ES 0657 - 55 - False color image of the distant galaxy cluster 1ES 0657 - 55 in the southern constellation of Carene obtained by the VLT. A gravitational mirage is visible in the form of a green arc at the top right of the image; it is the image of an even farther away galaxy curved and amplified by the gravity of this cluster. An Arc at z = 3.23 in galaxy cluster 1ES 0657 - 55. The galaxy cluster 1ES 0657 - 55 is located in the southern constellation Carina (The Keel), south of the Milky Way band. Its redshift has been measured as z = 0.29. It is a source of strong and very hot X - ray emission and has an asymmetric galaxy distribution, indicating a large mass and recent formation / Bridgeman Images

Webster led a short career in London from 1776 to 1780, despite his elegance and harmonious voice. Engraving in The Vocal Magazine, published by J.Bew in 1778. / Bridgeman Images
PIX4565586: Galaxy Clusters Abell 1689 - details - Gravitational lenses in Abell 1689 galaxy cluster - Close-up of the various gravitational mirages observed in the Abell 1689 galaxy cluster. Near infrared and visible image obtained by the Hubble space telescope in June 2002. 13 hours of installation. A selection of cropped images from a NASA Hubble Space Telescope Advanced Camera for Surveys view of one of the most massive galaxy clusters known, called Abell 1689. These close - ups show “” lensed”” images of background galaxies that have been brightened and smeared by the gravitational bending of light by the foreground cluster. The yellow - white objects are the cluster galaxies located 2.2 billion light - years away. The blue arcs are the distorted images of background galaxies located billions of light - years farther away than Abell 1689. The distribution of both “” normal”” and dark matter, and the alignment of the background galaxies determine the amount of distortion. In a perfectly aligned gravitational lens the background object would be smeared into an “” Einstein ring.”” Instead, there are numerous ring sections or arcs corresponding to individual galaxies. Though the galaxy images are distorted, numerous structural details such as star clusters and dust lanes are magnified. These would not normally be resolved without the lensing effect of the foreground cluster. Red objects in the field may be nearby cool stars, or galaxies at great distances. Images of the same galaxies are also mirrored on either side of the cluster. These distortions yield clues to dark matter in space, and the curvature of the universe. They also beautifully demonstrate Einstein's theory of general relativity that predicted that gravity warps space. This representative color image is a composite of visible - light and near - infrared exposures taken in June 2002 / Bridgeman Images
PIX4565601: Clusters of distant galaxies CL0024+1654 - Distant cluster of galaxies CL0024+1654 - False color image of cluster CL0024+1654 obtained with the 12k camera of CFHT (Canada France Hawaii Telescope) in Hawaii. This cluster is 4.5 billion light years away. This is a colour image of the galaxy cluster CL0024+1654 obtained with the CFHT12k camera at the Canada France Hawaii Telescope on Mauna Kea (Hawaii). Distance of 4.5 thousand million light - years (about one third of the look - back time to the Big Bang) from Earth. The cluster clearly appears as a concentration of yellow galaxies in the centre of this image although cluster galaxies actually extend at least to the edge of this image. This image measures 21 x 21 arc - minutes / Bridgeman Images
