Optical sparse aperture telescopes utilise an array of smaller, discrete subapertures to synthesise a large effective aperture, thereby achieving high-resolution imaging with reduced system mass and ...

The Atacama Large Aperture Submillimeter Telescope (AtLAST) is a concept for a 50m class single-dish telescope that will provide high sensitivity, fast mapping of the (sub-)millimeter sky. Expected to ...

Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to ...

The article discusses three main telescope types: refractors (best for bright objects, portable), reflectors (best for faint objects, larger apertures), and catadioptrics (compromise between aperture ...

Stars in the new images from the James Webb Space Telescope look sharper than they did before. And I’m not just talking about the image quality, which is astounding. I’m talking about the fact that ...
