? A deep space image of the galaxy NGC 5194 shows its sprawling landscape, with some of its stars visible as small points of light. In order to see these stars, the image was lensed using a telescope with a high-magnification lens. The resulting image shows a much closer view of NGC 5194, revealing intricate details on the galaxy's surface.

Lensing magnification is a phenomenon that occurs when light from a distant galaxy is bent and amplified by the gravity of a massive object, such as a galaxy cluster, that lies in between the distant galaxy and us. This amplification allows us to observe the distant galaxy with greater clarity and detail than we would otherwise be able to. Without lensing magnification, the distant galaxy would appear fainter and more difficult to observe. Therefore, lensing magnification is an important tool in astronomy for studying distant galaxies and understanding the universe.
