and losing the planet we call home.
故郷の星を失うかの間で揺れています
we've greatly expanded
私たちの知識は大きく広がりました
within the context of our universe.
何千も見つかり
around other stars,
1つにすぎないことを示唆しています
of billions of planets in our galaxy.
光が遮られることで起きる
as planets pass in front of them,
of that light from reaching us.
観測しています
その親星(恒星)までの距離を明らかにし
from their parent star.
whether these planets are small and rocky,
地球型惑星なのかどうか
in our own Solar System,
受けているのかが分かります
from their parent sun.
these planets that we discover
居住に適しているかの
as we're discovering this treasure trove
宝の山が発見されている一方で
人類の重みによって疲弊しています
under the weight of humanity.
最も暑い年でした
been with us for millennia
氷河や海氷が
in a matter of decades.
消失しています
changes that we have set in motion
この惑星規模の環境変化は
急速に進行しつつあります
to alter their course.
I'm an astronomer.
天文学者です
as influenced by stars
研究していて
the places in the universe
存在しうる惑星を
life beyond our own planet.
choice alien real estate.
と言ったところです
in the search for life in the universe,
私に言えるのは
you look for planets like Earth,
探せば探すほど
強く感じるということです
our own planet itself.
invites a comparison
見つかるごとに
and the planets we know best:
太陽系の惑星の比較を促されます
火星を考えてみましょう
and though it's a bit far from the Sun,
太陽から少し遠いですが
a potentially habitable world
タイプの惑星です
was habitable in the past,
居住可能だった可能性があり
we study Mars so much.
数多く行われてきたのもそれが理由です
crawl across its surface,
探査ローバーが
火星表面を走り回り
of life as we know it.
火星大気のサンプルを採取し
sample the Martian atmosphere,
might have lost its past habitability.
解明しようとしています
not just a short trip to near space
地球周辺の短期間の旅行だけでなく
of living our lives on Mars.
提示しています
of our own home world,
to ideas about pioneering and frontiers,
喚起するにしても
ひどい場所です
we have not colonized
砂漠が広がっていますが
豊かなものです
by comparison with Mars.
最も高地にある場所でも
highest places on Earth,
もたらす酸素に満ちた
by our rainforests.
about colonizing Mars and other planets
バラ色のアイデアが投げかける
私は懸念しています
本当に居住可能な惑星に
from the self-inflicted destruction
火星が人類を救ってくれる
we know of, the Earth.
もたらすことになるのか
interplanetary exploration,
まったく反対です
to go to Mars,
たくさんあるとしても
will be there to back up humanity
火星があると言うのは
telling you that the real party
本当のパーティーは
言うようなものです
exploration and planetary preservation
表と裏なのです
of the same goal:
and improve life into the future.
保護し 改善するということです
of our own world are alien vistas.
異星の光景のようで
というだけです
and maintain habitable spaces
荒涼とした地に
維持する方法が分かれば
spaces here on Earth,
of both preserving our own environment
役立てられます
thought experiment:
パラドックスという
asked that, given the fact
エンリコ・フェルミは問いました
for a very long time
と考えられるので
are many planets within it,
良さそうなものだが
for alien life by now.
to Fermi's paradox
考えられる答えの1つは
technologically advanced enough
進出しようとするほど
故郷を守ることの重要性を
that advancement to begin with.
that interplanetary colonization alone
などと考えるのは傲慢です
and interplanetary exploration
惑星間探査を
可能なのです
住めるように変えられると
for human habitation,
the far easier task of preserving
維持するという
克服すべきでしょう
ABOUT THE SPEAKER

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.
