[Applause]
yes yes this right up there on the
picture taken by the probe Voyager as it
reach the end the edge of our solar
system is our home the earth on it
everyone you love everyone you know
everyone who ever was now let’s take a
few second to try to grasp the Sun of
joy to some of suffering to some of hope
the some of despair the some of
misunderstanding but also the sum of
potential that lays within it within all
of us
the challenges that face our species our
ecosystem from political crisis to
large-scale hunger to endanger species
and climate change our all coli’s
calling for a better version of us as I
graduated from the University of liège
as an aeronautical engineer six years
ago now I believe that our species was
craving for something more more than
just further technological development
we had the resources we had the
technology what was missing was a shift
in mindset for this what we need is a
shift in perspective if we look back
what we see is this little bright dot
and this perspective shift allow us to
embrace how special how fragile how
beautiful it is
fortunately for us we humans are on the
verge of a profound perspective shift a
deep and well needed program shift
awaits as we are at the edge of finding
life elsewhere in the next generation
and right here
the goal of this talk not to talk about
the scientific details but rather to
provide you with a breaking new
day-to-day routine so we can step back
and contemplate where we add worry adds
as a species where we add as the
dominant conscious being on this horse
is floating through space in order to
sort of guard the earth our home we are
going to have to learn to work as one
human family and I do hope I believe
that these types of paradigm shift
perspective changes will help us move
toward this place the password will be
upon us now this game-changing paradigm
shift that are within reach tackled key
question that we’ve been asking ourself
for millennia being conscious we’re
looking for purpose why are we here we
turn to others are we alone to try to
find answers to these questions
interestingly enough when we think about
this fundamental question with pictures
our selves our friends our families
looking at the Stars
and this might be from there that the
unanswered to this question come when
you look at the sky if you’re not in the
cities you’ll see millions of stars
actually billions of them our galaxy the
Milky Way counts over 200 billions of
star now think about ours the Sun it has
produced eight planets so why would the
other not produce planets as well and
how about one of these harboring life a
biosphere as the earth does now you may
ask okay great but what the point that
is so far we won’t be able to go there
true yet I believe we can still get a
lot out of this I believe that thanks to
this new vantage point we can look back
at us and reflect and grow grow
hopefully faster that what we would do
if we had to wait together if ever
managed to nuts
destroy herself in the past to them now
the field that’s social planets around
other stars
study them is called exoplanetary
science to science that study exoplanets
planets around other stars and I’ll show
you how it has already started to change
our perspective on planetary system on
planets and I want you to keep an eye
that I hope that this field will help us
change our perspective on habitats on
life and hopefully on intelligence for
century our perspective on planets pair
formation cloud evolution has been based
on one in example the solar system
everything we’ve known or projected
related to observation of this beautiful
piece now what is the issue with that
well the issue that it’s exactly the
same thing is what you would be bothered
by if you were to try to predict the
outcome of political election by asking
opinions to member of one family
different individuals different planets
yet the same story the same values
change the same evolution and as we
started to find planets around other
stars in our sin then we started to be
challenged then our a perspective
progressively broaden we find near
planet types hot Jupiter for example
planets of the size of Jupiter but that
do not orbits a star in 11 years like
Jupiter does around the Sun didn’t only
in couple of days meaning that the
temperature there roasted by the star
the temperature it like reach thousands
of degrees we find planet without star
literally free-floating in the galaxy we
found planets with multiple star like
Kepler 16b that is two star and offer
this iconic double sunset is that Wynn
installed us among the exotic planet
found we found Jay 1406 B that has 37
rings about 200 times the extent of
Saturn rings being that if Saturn’s in
our system had two drinks you’ll be able
to see it by naked eye in the sky and it
will be larger than the moon we’ve found
planets literally dying around the star
as we speak being pulled apart by the
gravitational field that is how much
diversity we’ve already find in only 20
years with most in most of the time
facilities that were not even designed
to do this kind of science so think
about what’s to come how do we found
these planets this plants are small very
close to something extremely bright and
far away meaning that from our point of
view all of the light coming from the
system is coming from one tiny drop dot
of light mm-hmm an analogy would be to
trying to study a firefly right next to
a lighthouse from a thousands of
kilometer away with binocular good luck
with that
so one way to do this is to use a
technique that’s called transit
technique we search for this trap of
light where something is passing in
front of the star the star being the
main source of light the larger of the
area of the star being blocked the
deeper the flicks drop the louder the
planet the larger the flicks drop the
easier these are to be detected the
smaller is a star
the larger the fritter up you get the
point so flagship direct is directly
related to the array oratio planet to
star now it is great with this technique
in that when a planet is in front of its
star a tiny fraction of the stellar
light is going through the planet
atmosphere allowing you to study it and
what is happening then is about the same
thing is what is happening when you’re
pouring a liquid in your glass and your
brain is looking at it while your eye
brain is processing depending of what is
in the glass water lemon juice wine Oh
beer Trappe asparagus you will be able
to pick or process and understand what
is in this glass and what is affecting
the light it is exactly the same thing
that’s happening that we’re using the
technique we using to study planetary
atmosphere now are all planets of
interest in the context of searching for
signs of habitability signs of life no
what we’re looking for
our earth-sized planet
we are centric temperature planets
meaning that they are not too warm not
too cold are quite cozy now what we
could potentially habitable they may
have liquid water at their surface and
we want them to be amenable for
atmospheric studies meaning that we can
actually search for signatures of
habitability all signatures of life
having a planet that’s earth sized
temperate but on the other side of the
galaxy meaning that we can suit it is
not really of interest for us at this
stage finding small planets or sized
we’ve been able to do it it was tricky
but we got there earth size in temperate
we’ve done it as well and then for later
while that isn’t my said there’s been
this stressed about the fact that maybe
we actually wouldn’t be able to find the
one that our temperate earth sized and
amenable the one that I have this
winning combination and as you know now
I transitioned to astronomy because I
really wanted to play with this one
develop the technique to study them and
I was stuck with the big hot one that
Claire you have nothing to do with
something habitable we knew we would
have the facilities such as a James Webb
Space Telescope to be launched by NASA
in either at the end of 2018 facility
actually designed to search for by a
signature in the atmosphere of
exoplanets so I kind of stressor
actually sold for it or that I might
have to leave the field if we didn’t
stumble on this planet but then what are
you gonna have a go everything’s changed
I got a phone call by meteorology know
who works here at the University of
liège
and he told me that that’s it we got
them thanks to the Trappist telescope
which was built by the University
Village in Chile this is a prototype to
the scope pretty successful one by the
way he and his team together with
Emmanuel Shah had found the planets that
we were looking for were targets to
start searching for science of
habitability in sense of life the
planets were found around the stone are
called toppest one and what makes them
so special is the fact that the star
is really not like Everson it is way
smaller way cooler it’s actually called
an ultra-cool dwarf star it is ten times
smaller than our sin meaning that its
area is a hundred times smaller than our
Sun so the singular plot of planet in
front of it is a hundred times larger
than what it would be in front of the
Sun meaning the top is one planet even
so there are tiny earth sized we can
easily study them we didn’t find one
planets or two all three we directly
move from having zero target to search
for signs of habitability in signs of
life to seven yeah of T that’s right
seven temperate earth-sized planets
that’s it
with a prototype telescope so what do we
know about this planet what you see here
is an illustration at this stage we
really know little actually close to
nothing we know their sizes we know
their masses and we have an idea of the
temperature where the temperature range
where they may lay so we do know that
for all of them they might be spot of
their surface where they can harbor
liquid water they might be locally
habitable that’s it
so the best really is yet to come two
reasons first because this was detected
thanks to your prototype the team is now
scaling up through the speaker’s project
building an observatory in the north in
the southern hemisphere and which we’re
now trying to raise found to build in
the northern hemisphere as well with
these facilities speculoos we will be
able potentially to find five to ten
other system like this a large pool of
planet to search for signs of life
second as I said we know little to
nothing about the planet but we have
upcoming facilities that will allow us
to dive into the atmosphere find out
what they are made of if there are signs
of habitability all signs of life and
all of this will happen within the next
ten to twenty-five years so obviously
that got the world excited right after
the press conference we
in Washington DC this news was front
page of most of the world’s media outlet
over three billion people are affected
by the news half the world over close to
how the world’s population Britt but we
wanted more than just having people
receiving the news all of us here on the
day-to-day basis receive a massive
amount of news the metrics that really
matter to us is how people got engaged
and what you can see on this Google
trend right here is that there is a
massive peak of interest worldwide to
all the idea the concept of exoplanets
in mean that for about a week the world
started to look beyond the day to the
horizon bringing the point of view to
world well beyond the edge of our system
and this is what I am vision for a field
I do envisioning the planetary science
is a way to provide humanity with
perspective on other planets new vantage
point Vantage one that we can use to
look back at us look back at us and try
to remember on a day-to-day basis not
just every couple year on a day-to-day
basis how special how precious our
fragile our home is how small our
differences how common are similarities
but remembering this on a day to day
basis we can start to make this tiny
leap towards working together as one
human family we can start to save God
our home our earth thank you
