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 ...

A research team from the University of Tokyo/Kavli IPMU, Ehime University, and the National Astronomical Observatory of Japan (NAOJ) has succeeded in conducting the first, full-scale scientific ...

With 2009 being the International Year of Astronomy, it is an apt time to reflect on just how far telescope technologies have come, and speculate about the future. Just over 400 years ago, Hans ...

For decades, astronomers have searched for signs of extraterrestrial intelligence using radio telescopes and optical instruments, scanning the skies for artificial signals. Now, researchers are taking ...

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 ...

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 ...

How telescopes closed in on colliding neutron stars. Yellow contours show area of gamma ray burst detected by NASA’s Fermi telescope. White contours show the area of gravitational wave signal ...

Four-and-a-half months after the James Webb Space Telescope's Christmas Day launch, engineers have achieved near-perfect alignment of its complex optical system, setting the stage for final instrument ...

Astronomers are looking forward to opening a new window on the universe by posting high-resolution telescopes on the moon, and in orbit around it. There are numerous proposals to do this from ...

For the first time, astronomers have observed a celestial event through both conventional telescopes and gravitational waves. The collision of two super-dense neutron stars just 120 million ...
