The rapid evolution of diffractive optical elements (DOEs) is reshaping space telescope design by offering lightweight, compact and high-performance alternatives to conventional optical systems. These ...

A team of NASA researchers is developing new types of optical masks that could help enable the many orders of magnitude of ...

Optical aberration theory remains a fundamental component in the design and operation of space telescopes. With increasingly ambitious astronomical missions and the demand for high-resolution imaging, ...

Welcome to the Tuesday Telescope. There is a little too much darkness in this world and not enough light—a little too much pseudoscience and not enough science. We'll let other publications offer you ...

Using the James Webb Space Telescope, astronomers have investigated the star-forming region W51, resulting in stunning new ...

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 ...

A team of astronomers from the U.S. Naval Observatory (USNO), Naval Research Laboratory (NRL) and the European Southern Observatory (ESO) have successfully used the ultra high-resolution capability of ...

Upon arrival at NASA's Goddard Space Flight Center, the Optical Telescope Assembly for the agency's Nancy Grace Roman Space Telescope was lifted out of the shipping fixture and placed with other ...

The world's largest optical telescope is seen taking shape in an amazing image. The European Southern Observatory's Extremely Large Telescope (ELT) is being constructed on the Cerro Armazones mountain ...

Astronomers have discovered the first radio signals from a unique category of dying stars, called Type Ibn supernovae, and these signals offer new insights into how massive stars meet their demise.

Designed and built by ESO - the Very Large Telescope (VLT) and Extremely Large Telescope (ELT) are some of the world's most advanced optical telescopes that form the flagship facility for European ...
