Sara Seager OC astronomer and planetary scientist .[4] Massachusetts Institute of Technology and is known for her work on extrasolar planets and their atmospheres. She is the author of two textbooks on these topics,[5] [6] Popular Science [7] Discover Magazine [8] Nature [9] TIME Magazine [10] MacArthur Fellowship in 2013 citing her theoretical work on detecting chemical signatures on exoplanet atmospheres and developing low-cost space observatories to observe planetary transits .[11]
Background
[ edit ]
Seager was born in Toronto , Ontario , Canada, and is Jewish .[4] [12] [13] hair transplantation and the founder of the Seager Hair Transplant Center in Toronto.[4] [14]
She earned her BSc degree in Mathematics and Physics from the University of Toronto in 1994, assisted by a
NSERC University Undergraduate Student Research Award , and a PhD in astronomy from Harvard University in 1999. Her doctoral thesis developed theoretical models of atmospheres on extrasolar planets and was supervised by Dimitar Sasselov .[1] [2] [15]
She held a postdoctoral research fellow position at the Institute for Advanced Study between 1999 and 2002 and a senior research staff member at the Carnegie Institution of Washington until 2006. She joined the Massachusetts Institute of Technology in January 2007 as an associate professor in both physics and planetary science, was granted tenure in July 2007,[16] [17] [3]
She was elected a Legacy Fellow of the American Astronomical Society in 2020.[18]
She is married to Charles Darrow and they have two sons from her first marriage. Her first spouse, Michael Wevrick, died of cancer in 2011.[19] [20]
Academic research
[ edit ] Seager talking about exoplanets
Seager's research has been primarily directed toward the discovery and analysis of exoplanets ; in particular her work is centered around ostensibly rare earth analogs , leading NASA to dub her "an astronomical Indiana Jones."[21] super-Earth -type planet composed mainly of hydrogen and helium in an animation of one model of the exoplanet Gliese 581c . The term "gas dwarf" has also been used to refer to planets smaller than gas giants , with thick hydrogen and helium atmospheres.[22] [23] Marc Kuchner , Seager had predicted the existence of carbon planets .[24]
Seager has been the chair of the NASA Science and Technology Definition team for a proposed mission, "Starshade ",[25] occulting disk , used to block the light from a distant star in order for a telescope to be able to resolve the (much dimmer) light from an accompanying exoplanet located in the habitable zone of the star.[26]
In years since 2020, Sara has been focusing on work related to Venus, with the potential discovery of phosphine , a biosignature gas, in the upper atmosphere.[27]
Seager equation

Seager developed a parallel version of the Drake equation to estimate the number of habitable planets in the Galaxy.[28] [28]

Asteria Spacecraft
[ edit ]
Seager was the principal investigator of the Asteria (Arcsecond Space Telescope Enabling Research in Astrophysics) spacecraft,[29] cubesat designed to do precision photometry to search for extrasolar planets, a collaborative project between MIT and NASA's Jet Propulsion Laboratory . ASTERIA was launched into low Earth orbit from the International Space Station on 20 November 2017, and successfully operated until its orbital decay on 24 April 2020.
Venus Life Finder
[ edit ]
In 2020, Seager led a team proposing a mission Venus Life Finder [30] [31] Rocket Lab on the Electron rocket[32]
Honors and awards
[ edit ]
Seager was awarded the 2012 Sackler Prize for "analysis of the atmospheres and internal compositions of extra-solar planets,"[33] Helen B. Warner Prize from the American Astronomical Society in 2007 for developing "fundamental techniques for understanding, analyzing, and finding the atmospheres of extrasolar planets,"[34] [35] American Association for the Advancement of Science in 2012 and elected to the Royal Astronomical Society of Canada as an honorary member in 2013.[3] MacArthur Fellow .[36] American Philosophical Society in 2018.[37] Memorial University of Newfoundland in 2018.[38] Lex Fridman Podcast [39]
In 2020, she was appointed as an Officer of the Order of Canada .[40] Los Angeles Times Prize for Science and TechnologyThe Smallest Lights in the Universe.[41]
She was an honorary graduand at her Alma Mater, the University of Toronto Spring 2023 Convocation. [42]
In 2024, Seager was awarded the Kavli Prize in Astrophysics.[43]
