look
I pray my friend’s arms look here
and here there are thousands
look at a shooting star made want
quick
I was 7 years old and at the time I lived in
africa with the family of my best
friend
we had spent the holidays near
Mauritania where the desert offers them
most beautiful starry nights that I have
never seen and that night I felt
a very strong emotion an emotion
difficult to describe a mixed emotion
a feeling of magic a sensation
joy of appeasement of curiosity yes of
curiosity because see I had the
desire to understand what was in
going to happen before my eyes this
experience is actually
wonder and that emotion has
truly shaped my life
when you see at 7 years old when I
saw this shooting star
I made the secret wish that when I
will be great I will be astronauts and I
will travel to the stars
but see I’m here tonight
today to share with you a
little is sulking and wonder that
I’m when is the last time
you felt that feeling
wonder
it’s when think
for me it was just a second ago
because every time I talk about
stars every time I remember
these moments in the desert I have it
goose bumps and tonight well I have
want to share a little bit of
all that I would do that is you
telling things about a star
fascinating who I hope will be able
change your daily life a little
I would like to do that by telling you
I’m not an astronaut
at least not yet but that I travel
as a towards the stars
and how am I trying to bring the
maximum of people with me
the stars if ever all of them now
we went out we would send out full but there
has a wonderful one that does not appear
in the night sky necessarily because
that this star is the sun then
the pretty funny thing about the
sun is that we all know it is
omnipresent he is there all the time
when it’s gray it’s there at the top
of noni walkout had to shine from
thousand fires
and yet we tend to forget that
and the sun is also a source of
life the green plants we eat
and well they feed on
solar energy to exist
and if we were too far from the sun
also the sun did not exist and well
liquid water would not exist
exist only in the form of ice and
an image of the sun seen in light
visible
that is, the light that we have too much
human can not capture with our eyes
this picture was taken there is only
a few days and you see a sphere
yellow a powerful image I would say
image a little soothing a very image
familiar in fact what you see there
it’s only the surface of the sun and
above this surface there is a
atmosphere an atmosphere that we ourselves
can not see with our eyes
on one hand because well
the atmosphere to love it in rays
ultraviolet and its rays is revealed
are partly absorbed by the atmosphere
terrestrial and we as a species and
well we did not develop for
can see its ultraviolet rays
so we send telescopes in
space and that was the scop reveals the
splendor of the sun’s atmosphere –
really when I look at this
atmosphere and that I see her moving I
tell me but why the atmosphere of
sun is hot too
why is she so active
why is she so
complex
when I see the details of this
atmosphere and that I see this kind of
the picture I tell myself what’s raining
the sun, well yes
what you see there is a phenomenon
instability of the sun’s atmosphere
and that’s called coronal rain or
the crown is the most
hot from the sun’s atmosphere
so the next time you open
your umbrella probably tomorrow you
would say that even on the sun one can
sing in the rain before I
study the sun I did not have
realized how much live in the
neighborhood of a star is not everything
rest
because even if we are more
150 million km from our sun
150 million km and well in fact one
bathes all the time in a flow
of particles that comes from
sun in the images you see
the luminous flashes are eruptions
solar and its solar flares are
the most energy events
intense of our solar system
when these solar flares take place
well it dissipates energy from
energy equivalent to over thousands
thermonuclear bombs in a few
minutes only
it sends particles into space
energy and sometimes even big
magnetized clouds that are called
solar storms and its storms
solar to spread little in the direction
planets of our solar system
you say but we are on earth this
is going on in space that we
touch not too much and ben actually if because
that you see the solar storms
they can be the source of
malfunctions on our satellites of
malfunction telecommunications
on our navigation satellites like
for example the gps system and also the
malfunctions on our networks
electrical
on this picture you could europe
view of space
at night and I think we can see very
clearly our energy dependence
imagine all these lights
disappear in minutes
due to a solar flare a little
preoccupied renames another story
a few months ago a solar flare
was at the origin of a radio blackout
on earth a radio haka that takes place
unfortunately at the same time where we
needed these radio communications
to be able to reach people
most affected by the hurricane starts to there
In the Caribbean
see we are more and more aware
that finally the activity of our
sun impact enormously our societies
human
me as a physicist of the sun and
well I’m really trying to
understand what’s going on during these
solar flares to understand the
birth of these eruptions
I use images like the ones that
we come with homework but also
data that reaches us from probe
space that there was sent through the
solar system and using everything
dataset and well I try to
understand how these storms are born
in the atmosphere of the sun are going to get
spread in space and impact the
planets with always in mind that like
the weather on earth our impulses one day
able to predict them and ultimately what
I’m doing it’s not just that’s
look at the sun and the planets of
solar system
my research also pushes me to
ask questions in others
areas of astrophysics when
every night tirelessly our
telescopes point to the stars
well we ask ourselves the question of knowing
what does it mean to live in
the neighborhood of another star to that
his other stars are as active as
the sun at the time when one discovers
more and more exoplanets
we ask ourselves whether
good life
finally out of the sun then
you see even if my feet are anchored
on earth in my head she travels when
even to the stars and it was
wonderful years that I had when
I was 7 years old well I still have it
when I think of these stars but I read
also especially when
well I have these solar data these
spatial data that come to me on
computer
so that may seem to you completely
wacky but it’s true that I have this
feeling that I’m watching a portion of
the universe when I have data that
get to my computer because
that it’s a bit like I’m in
train there to watch a good universe
which was collected by a robot that we
human beings we launched into space
finally me it was crazy and
I never thought when I was 7
that years later I will be me
even working on a
space mission only referees hours
that you see here a mission to
the European space arrangement that is going
start in a few years and who will
get closer to the neighborhood of the sun
wonderment wonder
finally he was always there
the wonder
he has not seen the developments of
humanity are his themes events on
would never have looked inside
our body this fantastic machine one
would never have tried to imagine what
happens in developing medicine
understand the dn 100 wonder on
would probably never asked
question of how does the birds fly and
in this way built we had
of course we can not separate
the wonder of all
developments of humanity and myself
over and over again I got
asked how can I
bring this wonder to the public
how are we all
we live more and more in cities
it is increasingly difficult to
starry sky look how is this
that I can share with you this
wonder
how can I take the
arm of my friends and tell them look
here and here there are thousands of
canvases the answer she happened to me there
a few years ago when the
virtual reality technology and
of augmented reality have invested our
homes and when I see what
now the smartphone not do I’m getting
am told
why not then with a very filmmaker
little money is very little sleep
we challenged ourselves to make a
video
in virtual reality and take on
our space shuttle all the public
to make them travel from the land
until the sun you know what the
results we had were easily
wherever we go in schools in
the science festivals the teens the
adults children from 9 to 5 years old all
loved being in space and we were
showed what we already knew that
the wonder has no sex
the wonder has no color and
has no age so we think that the
technology
it’s a rich affair a business
to favor a desire a revolution
digital that affects the whole world our
smartphones become our computers
in emerging countries
almost half of the population has
and we undoubtedly think that in
future years
the first access to the internet will be by
smartphones imagine what we
can do with his jewels of
technology that we have in time
in our pockets imagine that we can
use virtual reality and the
augmented reality as vectors
of wonder what started as
an idea that I shared with my friend
Filmmaker has become one of my most
great challenges sharing my
wonder
so tonight I’m here with you for
do a little bit of my trip
would I like to make you
as a message, what is it?
you wonder what’s what
Worth wonders in the deepest of
you for me it’s clearly the
stars but for you what is that
it is and when you found it
how to share them with the world
full
I have not finished astronauts but little
I care
that I learned a lot more about
stars with the craft I do
today
and if in addition I can inspire them
future generations
if I can marvel them if I can
help them look at the starry sky or at
look ahead
so that’s good but then much more
than I had imagined what I
did not wish to 7 years this star
shooting near the Mauritanian desert
thank you
[Applause]
