Sara Seager: The search for planets beyond our solar system
About | Information | History | Online | Facts | Discovery
Every star we see in the sky has at least one planet orbiting it, says astronomer Sara Seager. So what do we know about these exoplanets, and how can we find out more? Seager introduces her favorite set of exoplanets and shows new technology that can help collect information about them — and even help us look for exoplanets with life.

super EARTH atmosphere need info suspect excess h2 in environment make air noxious to breathe

SHES AMAZING

Ms. Seager, You're freaking awesome. Thank you for your work..... oh by the way, the satellite, it's..... GORGEOUS!
Take that beautiful telescope + satellite, and find us some ET's! -
The larger lady at 4:51 doesn't understand the joke. I don't blame her, she's probably thinking if Kepler 16b has food or not.
-
I love how enthusiastic she is about her topic, you can clearly tell how much she loves what she does! good for her

Our Generation :-)

Aliens do exist. They do visit our planet. All I hope for is that the cover-ups are uncovered and officially acknowledged by the governments. Would be cool to have them walking around with us. Would be cool to call some of em as my friends, go for a drink with em perhaps? Jokes apart.. all I look forward to is acknowledgement of what is already out there.
-
There is a lot more out there than anyone can imagine..
-
she is my hero!
-
its so silly i think to believe there is no life outside of our planet. sure, there are no evidence to back it up, the possibility is endless

This is a brilliant example of the potential of science. 200 years ago theorists begin to understand optics mathematically. Then come advancements in engineering and materials science that allow us to build better telescopes. Then rocketry is developed and allows the telescopes to be put into space. Chemistry and biophysics are advanced and we learn that we can detect the presence of life from dozens or hundreds of light years away. Computer technology advances and allows data analysis that was impossible 30 years ago. The factors combine and we start finding planets around almost every star. Soon we will find earth like planets. If there is life there, we will know it. I hypothesize that just as we found exoplanets everywhere once we developed the ability to detect them, we will also find life on almost all earth like planets. After all, life bloomed here almost as soon as it was chemically possible. Intelligent life could be much more rare. There have been only a few species on earth that would be called intelligent by our standards. It is also likely that intelligence is such a powerful advantage that only one species per planet could develop with human level or higher intelligence. In the far future (not really so far, maybe 1000-2000 years?) we might be the interstellar traveling aliens we have been looking for. Is it possible that one day the children living on a dozen earths will read about a time when people thought looking for exoplanets or building telescopes was a waste of money and time?

Very interesting talk.
-
Cool I think she's an alien but I love her anyway.

Fascinant !! " Et en matière de savoir vous n'avez reçu que très peu'' Coran <3
-
Is Keplar 16 b K-PAX?
-
I think she did a beautiful job. Very professional and thorough.
-
Why can't other life forms live on hotter or colder planets unlike humans and animals? The planet just right for humans and other animals on EARTH may not be just right for other life forms we may not know about.

Super cool. I can't imagine all the details that go into preparing that ingenious star shade thing! May you find what you seek!
