KAIST researchers tested optical frequency comb lasers as reference signals for radio astronomy, aiming to synchronize radio telescopes with light-based timing in VLBI observations.

This animation, provided by the Max-Planck Institute for Extraterrestrial Physics (MPE), shows the path of light inside GRAVITY+, an instrument and a large and complex upgrade to ESO’s Very Large ...

The successful creation of a guide star above the European Southern Observatory (ESO) Paranal site in Chile with freshly installed lasers marks a new era of interferometry, according to the ESO team.

We now have direct images of two supermassive black holes: M87* and Sag A*. The fact that we can capture such images is ...

Hoping to see deeper into the universe, scientists and engineers are designing some of the largest and weirdest telescopes ...

Radio interferometric imaging represents a pivotal advance in astronomical observation by combining signals from distributed radio telescopes to synthesise high-resolution images of celestial objects.

The James Webb Space Telescope snapped its sharpest image of the area around a black hole, solving a long-standing galactic mystery.

This photograph shows four lasers at ESO’s Paranal Observatory, each one launched from one of the four eight-metre telescopes on site. The launch of these lasers represents a significant milestone for ...
