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. And to do ...

Use left and right arrow keys to seek audio. A ground-based telescope in Chile has shared its highest-resolution image ever, showcasing the final stages of star evolution within our galaxy 1,350 light ...

Plans are underway to add a seventh movable telescope to Georgia State University’s Center for High Angular Resolution Astronomy— known as the CHARA Array—that would increase the resolution, or the ...

The highest angular resolutions for telescopes can be achieved by arrays of telescopes called astronomical interferometers. Hypertelescopes are being worked on that would combine many, many telescopes ...

According to the widely accepted Rayleigh criterion, in order to resolve two distant point sources, their angular separation must be larger than 1.22 (the wavelength of light divided by the ...

The James Webb Space Telescope has captured images of three nearby galaxies with unprecedented resolution at infrared wavelengths, giving them a first look at star formation, gas and dust. Data has ...

The James Webb Space Telescope (JWST) started its science mission just a few weeks ago, surpassing all expectations while astonishing scientists and the public alike. Its infrared instruments and a ...
