This is the unique story of observing a total solar exlipse for no less than 74 consecutive minutes. On the summer morning of June 30, 1973, the Sun rises on the Canary Islands. But it is strangely indented by the Moon. The eclipse of the century has just begun. From the west, the lunar shadow rushes to the African coast at a velocity of over 2000 kilometers per hour. Astronomers on the ground will enjoy seven short minutes of total eclipse to study the solar corona - too short for Pierre Lena and seven scientists who board the Concorde 001 prototype, an extraordinary plane to become the first commercial supersonic aircraft. With André Turcat as chief pilot and a crew of five, at 17000 m altitude, the aircraft remains in the lunar shadow for 74 minutes, a record time of scientific observations not yet beaten and allowing for exceptional measurements. Science, technology, aviation and history combine in the story of a unique human adventure aboard a legendary aircraft, illustrated with a rich and original iconography. It reflects the wonderful domains that science and technology can open, and the passion in the professions they offer. A must read for every eclipse chaser and fan of true scientific adventures.

Une éclipse totale de Soleil offre toujours un spectacle extraordinaire, quoique limité à quelques minutes et à une zone étroite de la surface terrestre. Pourtant, le 30 juin 1973 au-dessus de l’Afrique, quelques astrophysiciens, embarqués à bord du prototype 001 de l’avion commercial Concorde et grâce à sa vitesse supersonique, demeurèrent dans l’ombre de la Lune pendant 74 minutes. Cette longue nuit permit de réaliser des observations astronomiques exceptionnelles et fut un record absolu, jamais battu depuis un demi-siècle. Science, technique, aéronautique et histoire se marient ici dans une aventure humaine singulière à bord d’un avion légendaire. Cinquante années après ce vol, la couronne du Soleil n’a pas encore livré tous ses secrets. Nuage ténu de gaz et de poussières, elle influe sur la Terre, crée les aurores boréales, agit sur les communications, peut mettre en danger les satellites. Pour mieux la comprendre, il faut en déchiffrer les images. Aujourd’hui, la grande aventure de l’astrophysique se poursuit avec la recherche des exoplanètes, astres jumeaux de la Terre qui sont immergés dans la couronne d’étoiles proches du Soleil. Ce livre témoigne des horizons de la science et des émotions inouïes qu’elle peut procurer à tous.

This is the updated, widely revised, restructured and expanded third edition of Léna et al.'s successful work Observational Astrophysics. It presents a synthesis on tools and methods of observational astrophysics of the early 21st century. Written specifically for astrophysicists and graduate students, this textbook focuses on fundamental and sometimes practical limitations on the ultimate performance that an astronomical system may reach, rather than presenting particular systems in detail. In little more than a decade there has been extraordinary progress in imaging and detection technologies, in the fields of adaptive optics, optical interferometry, in the sub-millimetre waveband, observation of neutrinos, discovery of exoplanets, to name but a few examples. The work deals with ground-based and space-based astronomy and their respective fields. And it also presents the ambitious concepts behind space missions aimed for the next decades. Avoiding particulars, it covers the whole of the electromagnetic spectrum, and provides an introduction to the new forms of astronomy becoming possible with gravitational waves and neutrinos. It also treats numerical aspects of observational astrophysics: signal processing, astronomical databases and virtual observatories.

This book addresses the changes in education practices, especially basic education, necessitated by the global challenges of climate change and sustainable development and in a context characterized by increasing poverty and inequality, migration and refugees. Written by a range of international scholars, scientists and grassroots practitioners from Africa, Latin America, Asia (India, China, Malaysia) and Europe, the individual contributions focus on education policies and child development in various social contexts. Case-based experiences from both developed and developing countries provide inspiration and shed new light on the fundamental changes needed to adapt existing school systems and teacher training to face the challenges of the future. In this regard, the need to empower children themselves is emphasized. All contributions are based on a Workshop hosted in November 2015 by the Pontifical Academy of Sciences at the Vatican entitled “Children and Sustainable Development: A Challenge for Education” and follow three other significant events on sustainable development in 2015, namely the publication of Laudato Si’, the Encyclical Letter from Pope Francis, the release of the United Nations Sustainable Development Goals, and the COP21 Conference in Paris. .
