The use of optical lasers between orbiting satellites are commonplace. Less common is using lasers from Earth to satellites.

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 ...

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 ...

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 ...

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 ...

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 Institut für Sonnenphysik (KIS) located in Freiburg, Germany, has installed a high-precision measuring instrument for the world's largest solar telescope, the U.S. National Science Foundation (NSF ...
