by anyone, everywhere,
ولأي شخص، ومن أي مكان،
beautiful things around us,
and we haven't even noticed,
we look at our computers,
even take the trouble
to looking up at the actual sky.
that the loss of our dark night skies
بأن فقدان سماء الليل المظلمة
of progress, change, technology.
والتغيير، والتكنولوجيا.
about my experience of the dark night sky.
عن تجربتي مع سماء الليل المظلمة.
sky until I was 15.
حتى بلغت 15 عامًا.
I pulled over somewhere.
ثم انعطفت بمكان ما،
except I know what state.
عن مكاني إلا اسم الولاية.
with an impossible number of stars.
you can see a couple of stars.
وعدد قليل من النجوم.
to be airplanes when they land.
who are astronomers
looking up at the sky in their backyard.
إلى السماء في الفناء الخلفي،
disappointing on camping trips.
you probably know them, too.
the dark night sky.
at how many stars there were.
"Where's this been hiding this whole time?
if you think about it
taken during a blackout
if you drown them out with light.
invisible light so we can see them,
التي تشع ضوءًا غير مرئي لنراها،
speaking, pretty cold.
like a blue-green marble
يشبه الرخام الأزرق والأخضر،
is reflecting off of it,
the oceans, the clouds, the land.
والسحب، والأرض.
to see the earth, right?
striking examples
our planet on a global scale.
across the globe everywhere.
من كل مكان في الأرض.
of ocean that are still dark,
من المحيط لا تزال مظلمة،
there's still darkness.
that this is a pretty global effect.
of places being lit up,
Times Square, the Vegas Strip.
مثل (تايمز سكوير) و (فيجاس ستريب)
these extreme examples,
dramatic effect on the ground.
is think about the shape of a lightbulb.
purpose of lighting up the indoors.
وهو الإنارة الداخلية.
your whole room, more or less.
if you're lighting the indoors,
in outdoor lighting,
light everywhere,
mostly what you care about
and your immediate surroundings.
outwards and upwards
light the area around you.
"light pollution."
about stargazing, this should worry you,
ينبغي أن يقلقك ذلك،
we use to light the outdoors
التي نستخدمها للإنارة الخارجية
I'm a big fan of technology.
every day; I'm a scientist.
كل يوم، فأنا عالمة.
to say that it's progress that --
we're going to all go live by candlelight.
جميعًا على ضوء الشموع.
to access the sky
of course, the Hubble Space Telescope.
هو بالطبع تلسكوب (هابل) الفضائي.
it returns pictures daily,
وهو يرسل الصور يوميًا،
with our naked eye,
to do before in all of human history.
من قبل في التاريخ البشري.
would be planetarium shows.
عروض القبة السماوية.
shows have become more high-tech
تطورت عروض القبة السماوية
directly to the sky,
بالسماء غير مباشر،
to our knowledge about the sky.
the sky in a planetarium
في عرض القبة السماوية
Space Telescope and of planetariums.
وعروض القبة السماوية.
for technology to enable participation
"citizen science projects."
research projects put their data online,
بيانات أبحاث ضخمة على الإنترنت،
to go and interact with that data
ليتفاعلوا مع هذه البيانات
characterizations about it.
أو ضرورية عن الموضوع.
I'm showing here, called "Galaxy Zoo."
ويدعى "حديقة المجرات".
even less than that, actually -- tutorial
لمدة 20 دقيقة أو أقل من ذلك
with these images of galaxies.
they're up and running,
useful categorizations
for people to be involved with:
لحديقة المجرات بين الناس:
speaking, pretty attractive.
of citizen science projects
من النكهات الأخرى لمشاريع علوم المواطن
people would jump at.
is the citizen science project
that I'm part of,
for planets around other stars
عن الكواكب حول النجوم الأخرى
from those stars very precisely.
من هذه النجوم بدقة شديدة.
some of that light.
project called "Planet Hunters."
مرتبط بذلك يدعى "صائدو الكواكب".
like Galaxy Zoo, a short tutorial,
يمنحكم تدريب مختصر،
you're up and running;
from the Kepler Mission
is an easy sell, right?
involves a lot of looking at graphs,
يتضمن النظر كثيرًا إلى رسوم بيانية،
and annotating them.
sound that interesting to me.
ولا يبدو الأمر مثيرًا بالنسبة لي.
interested in doing this,
that work with Planet Hunters
الذين اشتركوا بصائدي الكواكب
undiscovered otherwise.
from the paper that they published
who contributed are listed below,
جميع من ساهموا بالأسفل،
of people's real names
this is the first academic acknowledgment
أن هذا هو أول اعتراف أكاديمي
in the discovery process.
في عملية الاكتشاف.
that these are some out-of-work scientists
هم بعض العلماء العاطلين عن العمل
that are really into this.
who participate in these projects,
technical backgrounds.
is people's curiosity
of the scientific discovery process.
من عملية الاكتشاف العلمي.
of experiencing the sky
التي تساهم في التعرف على السماء
like looking at an animal in a zoo.
of experiencing that thing --
is still real,
than you can in the wild.
أكثر مما تستطيع في البرية.
in the wild for yourself,
surrounds every known living thing
تحيط بكل شيء حي
that has life on it.
الذي نعرفه ويوجد عليه حياة.
by every other living thing
نشاركها مع كل الأحياء الأخرى
that I really like about my work
from my every day
and try to find planets in the universe
على كواكب أخرى في الكون
of how precious what we have here is.
that you can visit
if we don't preserve it and treasure it,
you want to learn more about,
to visit darksky.org
about the choices you can make
it belongs to all of us,
to experience as we wish.
ABOUT THE SPEAKER
Lucianne Walkowicz - Stellar astronomerLucianne Walkowicz works on NASA's Kepler mission, studying starspots and "the tempestuous tantrums of stellar flares."
Why you should listen
Lucianne Walkowicz is an Astronomer at the Adler Planetarium in Chicago. She studies stellar magnetic activity and how stars influence a planet's suitability as a host for alien life. She is also an artist and works in a variety of media, from oil paint to sound. She got her taste for astronomy as an undergrad at Johns Hopkins, testing detectors for the Hubble Space Telescope’s new camera (installed in 2002). She also learned to love the dark stellar denizens of our galaxy, the red dwarfs, which became the topic of her PhD dissertation at University of Washington. Nowadays, she works on NASA’s Kepler mission, studying starspots and the tempestuous tantrums of stellar flares to understand stellar magnetic fields. She is particularly interested in how the high energy radiation from stars influences the habitability of planets around alien suns. Lucianne is also a leader in the Large Synoptic Survey Telescope, a new project that will scan the sky every night for 10 years to create a huge cosmic movie of our Universe.
