Il est enfin là! “Les secrets du Soleil”, mon tout premier livre, en collab. ac Sophie Garcin, sortira le 31 octobre en librairie et sur les sites marchands. Un voyage en image vers notre étoile, le Soleil, et au-delà. J’y ai mis beaucoup de passion, j’espère qu’il vous plaira!

I’ve been struggling finding good wifi since yesterday, now that I have, couldn’t resist sharing this pic of the breathtaking eclipse I saw yesterday. I can’t believe I study this beautiful star for a living!
Comme on me le demande dans les oreillettes... tous les index sont en baisse comparé à hier, donc on démarre moins bien ce soir...
MAIS
il y a encore des tempêtes solaires en direction de la Terre. L'activité aurorale risque de reprendre dans la nuit suivant leurs profils!
Et voilà!!! First images are out now, with all exquisite details of things that might help us understand some mysteries such as why the Sun's atmosphere, its corona, is so hot!

team at ESA/ESTEC for the next couple of years! V. excited to be working w/ a great team & my favourite mission under (around?) the Sun. & a new exciting campaign is starting in a few days! More below👇
Back in August this year, had the immense privilege to share the stage w/ some awesome

: zoom sur la région. Regardez bien les grandes boucles en bas à droite, vous verrez du matériel solaire (que l'on appelle du plasma) s'écouler le long de celles-ci. On appelle cela de la pluie coronale! Et oui, il "pleut" (du plasma) sur le Soleil!
Ahem… NON, les vents solaires (au générique) ne sont pas “extrêmement dangereux”. Le vent solaire lent, le vent solaire rapide, sont tous deux des phénomènes constants de notre environnement spatial, sans conséquence dangereuse (on ne serait pas là sinon). Même les tempêtes
"Nous subissons en ce moment la plus importante tempête solaire de ces 20 dernières années, liée à l'arrivée simultanée de plusieurs éjections de masse coronale" explique Quentin Verspieren (alias

a few months back when the spacecraft was shipped to the USA from Germany, and now I’m ready to say goodbye again to this beauty when it departs Earth tonight to our closest star, THE SUN!!!!

. Despite adverse weather conditions everyone kept a big smile on their face, what an epic event!
All the feelings!! My first PhD student just defended his thesis today 🥳 Congratulations to Dr Regnault for all the hard work, especially while dealing with a pandemic for half of the thesis! Now I'm hit by the academic empty-nest syndrome 🥺 (got smg in my eyes, brb)
Very honoured to receive the French astronomy&astrophysics society (
@SF2A_astro
) prize tonight, and meet new faces from my supporting community ☺️ thank you!!!
We all live under the same sun, on the same planet, sharing the same cosmic destiny. Yet the insufferable reality of lives taken for no reason but abuse of power… I have no words to express the sadness of it all. 🕊
This comparison is kind of a joke in today’s science world. I doubt Newton had to prepare for uni classes online, supervise students via slack, have endless zoom meetings, apply for grants all while protesting a government incapable of saving the future of research.
In 1665 Cambridge University closed because of plague. Isaac Newton retreated to rural Lincolnshire. During his 2 years in lockdown he worked out calculus, the true meaning of colour, gravitation, planetary orbits & the 3 Laws of Motion. Will 2020 be someone’s Annus Mirabilis?

X8.6 FLARE IN PROGRESS: This is the largest flare of solar cycle 25 so far and the largest flare since September 2017. As AR3664 is partly behind the SW limb this was probably an even larger flare. I'll post the video as soon as the data is available.

@pat_antolin
again, we’ve known each other since we were doing our PhDs in Japan, one in fusion one in solar physics… guess who influenced the other one 😜
Applied! Biggest incentive for me is that a more diverse applicants crowd will lead to a more diverse astronaut crew. I don’t have illusions on the outcome for me, but really excited to see future astronauts representing the diversity of Europeans in space!

Happy summer solstice! The longest day of the year in the northern hemisphere has been a glorious show of sunshine. Couldn’t be a better day to be reminded what an awesome star we orbit around! Here is a footage of rain falling on our 🌞 ain’t it beautiful?!😍

A key mission goal was to link the solar wind detected around the spacecraft back to its source regions on the Sun.
A new paper, using data taken during our first close approach to the Sun, confirms that it's possible.

Yes, I was excited to witness a space launch. Will I? I decided not to. Right now, I can’t stand that we, as humanity, are able to do incredible things & yet kill other humans on pretense of the colour of their skin, or their gender, or their sexual orientation, or their religion
