Extremely distant galaxies are usually too faint to be seen, even by the largest telescopes. But nature has a solution—gravitational lensing, predicted by Albert Einstein and observed many times by astronomers. Now, an ...

Magnification is the process of enlarging something only in appearance, not in physical size. This enlargement is quantified by a calculated number also called "magnification". When this number is less than one it refers to a reduction in size, sometimes called "minification" or "de-magnification".
Typically magnification is related to scaling up visuals or images to be able to see more detail, increasing resolution, using optics, printing techniques, or digital processing. In all cases, the magnification of the image does not change the perspective of the image.
