Combining a double natural "magnifying glass" with the power of ESO's Very Large Telescope, astronomers have scrutinized the inner parts of the disc around a supermassive black hole 10 billion ...
The magnification (or power) you will see through a given optical system depends on the telescope and the eyepiece. The simple formula is: Magnification = Focal length of telescope ÷ focal length of ...
Shini talks to us about optical instruments and how they make magnification possible. How do lenses work? How do they form images? Well, in order to understand how optics work, we have to understand ...
