Space rarely gives up its secrets easily. For instance, what looks like a single ...

To capture higher-definition and sharper images of cosmological objects, astronomers sometimes combine the data collected by ...

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

Hoping to see deeper into the universe, scientists and engineers are designing some of the largest and weirdest telescopes ever conceived. Come with our guest host Astro Alexandra on a tour of the ...

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.

Our project will increase the spatial resolution reachable in the optical by thousands, opening new fields of investigation in astronomy in general. For instance, images could be obtained of the ...

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 ...
