"Les secrets du Soleil" is out now! (French edition)
Nous évoluons dans le voisinage d’une étoile fascinante, à la fois proche et mystérieuse. Depuis la nuit des temps, nos yeux se sont tournés vers le Soleil, et nous pensons le connaître : son fonctionnement, sa présence à la fois rassurante quand dardent ses rayons et inquiétante quand il est question du réchauffement climatique. Pourtant, la science n’en finit pas de révéler de nouveaux phénomènes surprenants, qui ont des incidences directes sur notre vie.
Saviez-vous, par exemple, que le Soleil n’est pas (que) jaune ? que sa surface n’est pas lisse ? qu’il y pleut, qu’il y vente, et même qu’il existe d’autres soleils ?
L’astrophysicienne Miho Janvier, spécialiste du soleil, nous invite à explorer ces phénomènes, à la lumière des extraordinaires clichés rapportés de missions spatiales.
À 150 millions de kilomètres de notre Terre, un voyage en images, à la découverte des plus beaux secrets du Soleil.
BIOGRAPHY
Miho Janvier is a solar and space physicist working at the European Space Agency (ESA/ESTEC, NL) as a Project Scientist for the ESA/NASA Solar Orbiter and SOHO space missions.
​
After obtaining her doctorate degree in plasma physics with applications to nuclear fusion science, she developed her research and expertise to better understand how solar flares occur, how solar storms travel in space and how they impact planetary environments in the solar system. She holds a civil servant position as an Associate Astronomer at the Institut d’Astrophysique Spatiale (France).
​​​
As a Project Scientist, Miho works closely with partners around the world to enhance data collection during the Solar Orbiter observation campaigns. These include missions from NASA (IRIS, Parker Solar Probe), JAXA (Hinode), as well as ground-based telescopes such as the Daniel K. Inouye Solar Telescope in Hawaii, Big Bear solar observatory in California, and facilities in the Canary Islands. These coordinated campaigns are crucial to obtain a comprehensive dataset of our Sun.
With almost 30 years of activity, the SOHO mission is the single long-lived space mission monitoring the Sun and the solar wind. As a project scientist on the mission, her work involves taking care of the unique dataset collected by the various instruments on the spacecraft, and its legacy.
Her passion for astrophysics and science communication has led her to develop several science communication projects, and has set up a non-profit organisation called SpaceTravelVR (www.spacetravelvr.com). She partnered with the movie production company TreeHouse Digital Ltd to develop a 360 degrees experience of a solar storm using science data and VFX, and has developed in partnership with the French national space agency CNES and ESA a project showcasing the Solar Orbiter mission in Virtual Reality. She is also a public speaker, as well as a keen communicator.
​
Miho was named WIRED UK Innovation fellow in 2016 and is a TED Fellow since 2017
