Coatings produced via atomic layer deposition (ALD) or ion-beam sputtering (IBS) offer dense film structure, superior ...

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 ...

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 ...

The telescope primarily detects light in the infrared in order to observe sources such as the first galaxies and protostars.

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 ...

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 ...

Every area of interest, particularly if it’s the least bit technical, has its own specialized vocabulary. For example, when the Global Positioning System (GPS) came along and I decided to get a ...

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 ...

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 ...
