Launch of the Eclipse Info 2026 initiative
20 April 2026On 16 April 2026, the magnificent Cassini Hall at the Paris Observatory – PSL hosted the press conference for the ‘Éclipse Info 2026’ initiative, attended by numerous journalists.
The aim of the event was to present the upcoming solar eclipse on 12 August 2026, which will be visible in Europe, as well as the national ‘Éclipse Info 2026’ initiative, coordinated by the AFA with the participation of several scientific institutes.
Following an opening address by the President of the Paris Observatory – PSL, Philippe Stee, the Time and Space Laboratory (LTE) explained how an eclipse works and presented the ÉclipSEOP app, developed by the LTE to enable observers to access the eclipse ephemeris based on their location. Milan Maksimovic, Research Director at LIRA (see photo), also spoke, discussing the properties of the Sun and the scientific challenges associated with its observation.
To mark the occasion, LIRA, in partnership with all the laboratories of the Paris Observatory – PSL, has created a downloadable educational leaflet so that everyone can easily access the essential information needed for successful observation!

Presentation
LIRA, a CNRS joint research unit at Paris Observatory, is a laboratory of excellence in astrophysics and instrumentation. It studies astrophysical objects, from the Solar System to our Galaxy and beyond, through five thematic areas. Through international collaboration and instrumental innovation, it pushes back the frontiers of science and contributes to the training and dissemination of knowledge.
Our projects
MIRS on the JAXA MMX mission
The Martian Moons eXploration (MMX) mission of JAXA (Japan Aerospace Exploration Agency) is the first sample-return mission from the Phobos satellite. It also includes an exploration of the Martian system. The mission’s primary objective is to decipher the origin of Martian moons, which will provide important information on planet formation and the conditions for the emergence of water on Earth-like planets.
The MIRS (MMX InfraRed Spectrometer) instrument, developed under the leadership of LESIA (now LIRA), is an imaging spectrometer that will characterize the composition of the Martian system and help select candidate sites for sample collection.
GRAVITY+
The GRAVITY instrument, installed on the European Southern Observatory’s Very Large Telescope Interferometer (VLTI/ESO), has produced spectacular and transformative results on the supermassive black hole at the centre of the Milky Way, the active nuclei of other galaxies, proto-planetary disks around young stars and exoplanets. GRAVITY+ aims to modernise both VLTI and GRAVITY to make them ≈ 100 times more sensitive, while increasing sky coverage by a factor of ≈ 100, and contrast in the vicinity of bright objects by a factor of ≈ 10. These gains will benefit all the VLTI’s current and future instruments for the next 20 years, and will perpetuate it as a unique infrastructure in the world.
