It's difficult to comprehend the size of the universe. It is hard to imagine the size of our universe. There are many groups of galaxies that interact with each other and come together in large groups.
Abell 1351, located in the constellation of Ursa Major, is depicted in the Hubble Space Telescope image. The mass of a group of galaxies is measured on the scale of the mass of the sun. The effect that mass has on space-time is shown in this observation.
There are streaks of light across the picture. The mass of the galaxy cluster warps space-time so much that it causes light to spread out like a magnifying glass. It is possible to see objects that are far away than we could normally see.
The mass of the object acting as a lens determines the degree of lensing. You can see multiple images of the same light source if the lens is large enough and the light source is close. That is a type of lensing. Weak gravitational lensing is an effect in which the light source is far away, which can stretch the light source and make it appear larger or a different shape.
Microlensing is a method of detecting exoplanets, in which light from a distant object appears brighter because of the body in front of it.
Both strong and weak microlensing are caused by Abell 1351, and the cluster is being studied to determine its mass and how distant it is.
Hubble scientists say that this observation is part of an album of snapshots of some of the most massive galaxy clusters. Strong gravitational lensing is one of the interesting astrophysical phenomena that can be seen in this bunch of massive clusters.
