As the diameter of a telescope's mirror increases, so does the angular resolution (the ability to ... period of a Cepheid's pulse cycle, and the derived luminosity combined with its apparent ...

How can you fairly compare one telescope to another? It's all in the (angular) resolution. The entire point of introducing telescopes into astronomy is to make distant things more visible.

Just how powerful is the world's most powerful telescope? Let's start with the human eye. The human eye has an angular resolution of about 1 arcminute. That's pretty impressive. Take a circle ...

The band-to-band method significantly enhances ALMA's high-frequency capabilities, enabling the telescope to observe objects at an angular resolution of 5 milli-arcseconds, which is equivalent to ...
