The NASA/ESA Hubble Space Telescope captured this huge galaxy cluster, referred to as Abell 1351, with its Wide Field Camera 3 and Advanced Camera for Surveys. Abell 1351 lies within the constellation Ursa Major within the northern hemisphere.
This picture is full of streaks of sunshine which are literally the pictures of distant galaxies. The streaks are the results of gravitational lensing, an astrophysical phenomenon that happens when a large celestial physique similar to a galaxy cluster distorts spacetime strongly sufficient to have an effect on the trail of sunshine passing by means of it, nearly as if the sunshine had been passing by means of a huge lens. Gravitational lensing is available in two varieties—sturdy and weak—and each may help astronomers decide the distribution of mass inside a lensing galaxy cluster similar to Abell 1351.
This commentary is a part of an astronomical album that holds snapshots of a few of the most huge galaxy clusters. This menagerie of huge clusters demonstrates fascinating astrophysical phenomena similar to sturdy gravitational lensing, in addition to showcasing spectacular examples of violent galaxy evolution. To acquire this astronomical album, astronomers proposed a Snapshot Program.
Snapshot Programs are lists of separate, comparatively quick exposures which might be slotted into gaps between longer Hubble observations. Having a big pool of Snapshot candidates to dip into permits Hubble to make use of each second of observing time attainable, maximizing the scientific output of the observatory.
