WASHINGTON, Feb. 5 – Future telescopes, with mirrors half the size of a football field, will need special components to deal with the light they collect. Astronomers are turning to photonic devices ...

India’s largest 3.6 metre Devasthal Optical Telescope (DOT) was commissioned in 2016, though the idea of building it germinated way back in 1976. This article provides research accounts as well as ...

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 ...
