“When we explore other worlds, what once seemed the only way a planet could be turns out to be somewhere in the middle range of a vast spectrum of possibilities…” 

― Carl Sagan, Pale Blue Dot: A Vision of the Human Future in Space


The Carl Sagan Institute (CSI) was founded to find life in the universe. Based on the pioneering work of Carl Sagan at Cornell, our interdisciplinary team is developing the forensic toolkit to find life in the universe, inside the Solar System and outside of it, on planets and moons orbiting other stars.

Recent scientific results show that in our galaxy alone there are billions of planets orbiting other suns. After billions of years of evolution on our own Pale Blue Dot and thousands of years of questioning, we finally have the technology in hand to explore other worlds inside and outside of our solar system. The information generated by the search for signs of life on other worlds also helps us understand and safeguard our own planet — our Pale Blue Dot — better.

CSI for the search of life in the universe: CSI explores factors that determine if a planet or moon can host life and how we could find it by bringing together experts from a wide range of disciplines, from sciences, engineering to media who work together with some of the planet’s most talented students at the undergraduate, graduate and postdoctoral level. CSI researchers use the latest data from space telescopes, probes to the solar system’s diverse worlds, field and satellite data on our home planet, laboratory studies of terrestrial organisms, and modeling of complex processes from the astronomical to the biological to explore these profound questions. And CSI researchers participate in the development of the next generation of space- and Earth-based facilities to probe ever deeper and farther.

CSI also interprets these results for the widest possible audience, sharing the fascination of science with everyone who is interested in where humankind stands in the quest to understand our place in the cosmos.


The Carl Sagan Institute was founded in 2015 at Cornell University to find life in the universe and explore other worlds – how they form, evolve and if they could harbor life both inside and outside of our own Solar System. Directed by astronomer Lisa Kaltenegger, the Institute has built an entirely new research group, spanning 14 departments at Cornell and including more than 25 faculty who focus on a wide range of the search for life in the universe interdisciplinarily.

The research group is embedded in a rich environment of established international interdisciplinary cooperation at Cornell. The Institute’s collaboration brings together researchers from fields as far apart as astrophysics, engineering, earth and atmospheric science, geology and biology to tackle questions as diverse as those about the astronomical context of the emergence of life on Earth, how to find it and what this discovery would mean for humankind.

Thank you so much for considering to support the vision of the Carl Sagan Institute and the Search for Life in the Universe. Gifts to support the Carl Sagan Institute (CSI) should be made out to “Cornell University” with a note that the gift is designated for the Carl Sagan Institute in the Department of Astronomy, College of Arts & Sciences. As these will be gifts to Cornell University, they fall under the university’s 501c3 tax-exempt status.

Gifts can be made by check, securities, or on-line. Please see the following web site for details:https://giving.cornell.edu/waystogive/

If making a gift on-line, please select “Other – Arts & Sciences” and fill in “Carl Sagan Institute, Department of Astronomy” in the dialogue box. For further details please contact David K. Whitmore – dkwhitmore@cornell.edu

Monthly CSI coffee hour
Carl Sagan Institute Coffee hour is held every first Thursday of the month at 1:30pm to lively discuss new research topics in an open interdisciplinary environment. Let Jill know, if you would like to join the discussion (and/or become a CSI member).

The Inauguration of the Carl Sagan Institute, a journey to discovered and undiscovered worlds, was held on May 9, 2015, from 9 am to 6 pm at Kennedy Hall, Cornell University. You can watch the talks here: http://www.cornell.edu/video/playlist/carl-sagan-institute-inauguration

Have you wondered…what it was like to find the first exoplanets around dead stars and Sun-like stars? What huge obstacles had to be overcome to launch the groundbreaking Kepler mission? What are the limits of extreme life on Earth? What the newest Kepler results tell us about planets and our place in the universe? How the “origins of life” question connects to the search for exoplanets?

On May 9th, hundreds of people came to Cornell to find out answers to these questions, and more. They were part of the excitement of the search for planets around other stars and the question of whether we are alone in the universe. The day featured inspiring international speakers talking about the challenges and excitement of their search for the first exoplanets, as well as the newest results of the search for Pale Blue Dots. Participants had an opportunity to ask questions and view 3D exoplanet projections and a Lego mock-up showing how transit search really works.


In the morning session, speakers shared their discoveries of the first new worlds and what it took to get Kepler off the ground. In the afternoon, speakers looked toward the future, considering the origins and extremes of life and Kepler’s newest results.

  1. all the success in the world in this project.

  2. Vassilis Charmandaris March 24, 2015 at 4:13 pm

    As an ex-resident of 106 Space Sciences Bldg. I send you my best wishes for yet another exciting project to be started at Cornell. What an inspiring name for the Institute! Consider an unlimited supply of bagels at CTB for the person who came up with it…

  3. Vatsal Panwar May 9, 2015 at 6:02 pm

    Please correct the name of the webpage when it is accessed. It says “Caral Sagan Institute” instead of “Carl Sagan Institute”.

  4. Best wishes for success! Carl Sagan is one of my heroes.

  5. Sail on bright star… and best fortune with this wonderful endeavor!

  6. Great! I can’t wait for the moment when we’ll finely find that other blue dot.

  7. Andriz Vegas López May 19, 2015 at 8:54 pm

    Hi Lisa, I’ve seen many videos of you, all of it related with astronomy. There is the ‘share-passion-speaking’ in the way you speak about it —as Sagan did—.

    Congrats. My best wishes for you with the Carl Sagan Institute. Someday I will be part of it!

  8. Looks like a great initiative. Is there a way I could be notified over email of new web posts? Thanks in advance and all the best!

  9. Carl Sagan has been a major influence on my artwork. As an artist, who also has an interest in astronomy and planetary science, I love to find ways to combine the two passions. I currently have exhibit in the Eastern Florida State Planetarium art gallery, “Visions of the Cosmos”, that honors the memory of Carl through art.

    This PDF docent brochure contains images of all the works in the exhibit along with descriptions of their meaning:

    This is the official press release for the exhibition:

    I would love to hear feedback and comments.
    Thank you!

  10. A followup and update to my last post: Due to its popularity, the “Visions of the Cosmos” art exhibition in the Eastern Florida State Planetarium art gallery, in Cocoa, Florida, has been extended two more months to August 13, 2016 (it was to end on June 11th). This exhibition contributes to STEAM program goals (Science, Technology, Engineering, Arts, and Math) and it functions to foster interest an in science through art. I am conducting a series of personal docent tours in which I share my perspectives on both astronomy and painting (as well as several concepts that blend the two). I believe this is in alignment with the part of CSI’s mission statement that says: “CSI also interprets these results for the widest possible audience, sharing the fascination of science with everyone who is interested in where humankind stands in the quest to understand our place in the cosmos.” I am honored to contribute in some small way to this goal.
