Current array
The growing array of telescopes at El Roque de los Muchachos already drives astrophysics research and will soon offer even greater capabilities to explore the universe.

“Relative uncertainty of measured stellar diameters as a function of their B magnitude for the current MAGIC interferometer, an extension to MAGIC and LST-1, and a further extension to MAGIC and the four LSTs in La Palma.”
Planned observatory (2028)
The growing array of telescopes at El Roque de los Muchachos already drives astrophysics research and will soon offer even greater capabilities to explore the universe.
Telescopes of El Roque de los Muchachos Observatory expected to operate as intensity interferometers by 2028.
“Relative uncertainty of measured stellar diameters as a function of their B magnitude for the current MAGIC interferometer, an extension to MAGIC and LST-1, and a further extension to MAGIC and the four LSTs in La Palma.”
