Spain is preparing to make a breakthrough in global astronomy: a project has been launched in Andalusia that could change the approach to searching for life beyond Earth. Thanks to new technology developed in Granada and Almería, the region could become one of the leading centers for exoplanet research. For the country, this is not only a matter of prestige but also a chance to create new jobs and attract investment in high-tech industries.
According to El Espanol, work has begun at the Calar Alto Observatory (Calar Alto) and the Instituto de Astrofísica de Andalucía on a system that will allow the combination of light from numerous small telescopes. This approach will make it possible to obtain images comparable in quality to those from a 15-meter telescope, while construction costs will be significantly lower than those of conventional giant mirrors.
Technology of the future
The project is based on photonic technology, which is only just beginning to be actively implemented in astronomy. It enables the collection and analysis of light from different telescopes, creating a single powerful system. A prototype, the MARCOT Pathfinder, has already been built and is expected to achieve an equivalent aperture of 5 meters by 2030. This will make it possible to observe more than 3,000 nearby stars and search for planets in their orbits where life could exist.
Previously, the largest Calar Alto telescope allowed the study of only about 330 stars. The new system will increase this figure by almost ten times. According to Ale Espanol, the project is supported not only by Spanish authorities but also by international research centers from Germany and Australia. Funding from the Andalusian government has already exceeded seven million euros in recent years.
New opportunities for the region
A key part of the initiative was the creation of a specialized astrophotonics laboratory in Granada. Here, key components for future telescopes will be produced. The lab is expected to be fully operational by the end of 2026. This step opens up prospects for Andalusia not only in science but also in industry: photonic technologies are in demand in medicine, telecommunications, and defense.
The Calar Alto Observatory is located at an altitude of over 2,000 meters in the Sierra de los Filabres mountains. It is one of Europe’s most advanced astronomical sites and a key scientific facility in Andalusia. Experts from various countries are already working here, and new investments will help attract even more specialists and young scientists.
Global cooperation
The E-MARCOT project is being carried out with the participation of the Spanish National Research Council (CSIC) and international partners. This collaborative approach strengthens Andalusia’s position on the world’s scientific map. If the technology proves effective, the region could offer the world a new model for building large telescopes—one that is more accessible and environmentally friendly.
In the coming years, there are plans to increase the system’s equivalent aperture to 15 meters. This will allow Spanish scientists to conduct research previously possible only at the world’s largest observatories. If successful, Andalusia will become one of the leaders in astrophotonics and the search for life in the universe.
In recent years, there has been growing global interest in the search for exoplanets and the analysis of their atmospheres. For example, in 2025, a new telescope was launched in Chile, which also uses combined technologies for observing distant stars. Similar systems are being developed in the US and Japan, but the Spanish project stands out for its focus on accessibility and scalability. Such initiatives help countries not only strengthen their scientific standing but also develop new high-tech sectors of the economy.
