The largest ground-based optical telescopes in use today use mirrors that are 10 m (33 ft) across. But the prospects for future Extremely Large Telescopes (ELTs) are looking up. According to recent ...
Prior to World War II the vast majority of telescopes built around the world were funded by wealthy people with an interest in the heavens above. However, after the war, two significant developments ...

Dramatic evening light shines above the clouds on the observatory and its large astronomical telescopes on the dormant volcano of Mauna Kea in Hawaii. Mauna Kea is considered sacred by native ...
In a new publication from Opto-Electronic Advances; DOI 10.29026/oea.2021.210040, Researchers led by Professor Daewook Kim from The University of Arizona, Tucson, AZ, USA consider advances in optical ...
Using the Hubble Space Telescope (HST) and Jansky Very Large Array (VLA), astronomers have investigated an ultra-diffuse galaxy known as UGC 9050-Dw1. Results of the study, published June 9 on the pre ...
Astronomy has always relied on optical instruments, from the early Galilean telescope to fiber-fed spectrographs, so much so that astronomy and modern optics are called astrophotonics. Since ...
