Last week, four lasers were projected into the sky above the European Southern Observatory (ESO) Paranal site in Chile. The lasers successfully created an "artificial star" that astronomers can use to ...

To capture higher-definition and sharper images of cosmological objects, astronomers sometimes combine the data collected by several telescopes. This approach, known as long-baseline interferometry, ...

The universe holds endless mysteries, and today’s most powerful telescopes are helping us explore them like never before. These advanced instruments drive the progress of modern astronomy, using radio ...

Georgia State University's Center for High Angular Resolution Astronomy (CHARA), a six-telescope interferometer, excels at studying stars. It's been observing them for 20 years and has contributed to ...

In optical interferometry, waves of a light signal travel to separate light collectors, and the interference pattern formed by superimposing the waves reveals spatial information about the light ...

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.

Astronomers have now produced the highest resolution direct images ever taken of a supermassive black hole in the infrared, using the Large Binocular Telescope Interferometer. Active galactic nuclei ...
