Natalie M. Batalha (born 1966) is professor of Astronomy and Astrophysics at UC Santa Cruz. Previously she was a research astronomer in the Space Sciences Division of NASA Ames Research Center and held the position of Science Team Lead (2010 - 2012), Mission Scientist (2012 - 2016), and Project Scientist (2016 - 2018) on the Kepler Mission, the first mission capable of finding Earth-size planets around other stars. [1] [2] [3] Before moving to NASA, Batalha was a Professor of Physics and Astronomy at San Jose State University (2002 - 2012).
Batalha grew up in the San Francisco Bay Area, and attended the University of California, Berkeley. [4] [5] Though she started out as a business major, she switched to physics after learning that everyday occurrences like thin-film interference (why rainbows appear on soap bubbles and oily puddles) could be described mathematically. During her undergraduate, she worked as a stellar spectroscopist, studying sun-like stars. After graduating with her bachelor's degree in physics, she pursued a doctorate in astrophysics from UC Santa Cruz, and completed a post-doctoral fellowship in Rio de Janeiro, Brazil. [3] [2]
Batalha's daughter Natasha Batalha is also an astronomer. The two women are collaborating on projects that discover and describe exoplanets found using the James Webb Space Telescope. [6]
In 1997, William Borucki added Batalha to the science team and she started work on transit photometry. She has been involved with the Kepler Mission since the design and funding, and as one of the original Co-Investigators was responsible for the selection of the more than 150,000 stars monitored by the telescope. She now works closely with team members at Ames Research Center to identify viable planets from the data of the Kepler mission. She led the analysis that yielded the discovery in 2011 of Kepler 10b, the first confirmed rocky planet outside the Solar System. [3] [7]
In November 2017, the Space Telescope Science Institute selected 13 programs for Director's Discretionary Early Release Science (DD-ERS) on the James Webb Space Telescope. [8] [9] Of a total of 460 observation hours allocated, Batalha's project, 'The Transiting Exoplanet Community Early Release Science Program', was awarded 86.9 hours; the highest of any DD-ERS program on the JWST. [10] These observation hours are allocated to be used during the first five months of the telescope's operation.
Batalha leads the UC Santa Cruz Astrobiology Initiative, a collaborative, interdisciplinary initiative dedicated to the study of the origin, evolution, and distribution of life in the universe.
Following the successful launch of the James Webb Space Telescope in 2021, Batalha and a team of researchers found unambiguous evidence of carbon dioxide in the atmosphere of an exoplanet. [11] The team used JWST to observe a Saturn-mass planet called WASP-39b which orbits very close to a sun-like star about 700 light-years from Earth.
Batalha, along with Mark Clampin, Astrophysics Division Director, National Aeronautics and Space Administration, and Steven L. Finkelstein, Professor of Astronomy, University of Texas at Austin, testified before the House of Representatives Committee on Science, Space, and Technology, Subcommittee on Space and Aeronautics in 2022. [12]
Batalha and the JWST Transiting Exoplanet Early Release Science Team used the James Webb Space Telescope in 2023 to identify water vapor in the atmosphere of WASP-18b and make a temperature map of the planet as it slipped behind, and reappeared from, its star. [13]
Batalha presented 'A Planet for Goldilocks' at Talks at Google in 2016. She presented 'From Lava Worlds to Living Worlds' at Breakthrough Initiatives in 2019. [14] [15]
In 2011, Batalha was awarded NASA's Exceptional Public Service Medal for outstanding leadership of the Kepler Science Team.
In 2017, Batalha and two other exoplanet scientists were named to Time Magazine's 100 Most Influential People in the World. [16] In the same year, Batalha won Smithsonian Magazine's American Ingenuity Award in Physical Sciences. [17]
In 2018, Batalha received the UC Santa Cruz Alumni Achievement award. [18]
In 2019, Batalha earned an honorary doctorate from the Faculty of Science and Technology at the University of Uppsala, Sweden. [19]
Batalha was elected a member of the American Academy of Arts and Sciences in 2019 [20] and a Legacy Fellow of the American Astronomical Society in 2020. [21]
In 2020, Batalha was appointed as a UC Presidential Chair for her work on the UCSC Astrobiology Initiative. [22]
Batalha has been awarded several named lectureships, including the James T. Bunyan Lecturer (2011, Stanford University), the Rittenhouse Lecturer (2015, University of Pennsylvania), the Walter Stibbs Lecturer (2016, University of Sydney), the Beatrice Hill Tinsley Lecturer (2017, New Zealand), the Carl Sagan Distinguished Lecturer (2018, Cornell University), the Celsius Lecturer, (2018, Uppsala University), the John N. Bahcall Distinguished Lecturer (2019, Space Telescope Science Institute), and the UCSC Faculty Research Lecturer (2024, University of California, Santa Cruz).
The Kepler space telescope is a defunct space telescope launched by NASA in 2009 to discover Earth-sized planets orbiting other stars. Named after astronomer Johannes Kepler, the spacecraft was launched into an Earth-trailing heliocentric orbit. The principal investigator was William J. Borucki. After nine and a half years of operation, the telescope's reaction control system fuel was depleted, and NASA announced its retirement on October 30, 2018.
Kepler-7b is one of the first five exoplanets to be confirmed by NASA's Kepler spacecraft, and was confirmed during the first 34 days of Kepler's science operations. It orbits a star slightly hotter and significantly larger than the Sun that is expected to soon reach the end of the main sequence. Kepler-7b is a hot Jupiter that is about half the mass of Jupiter, but is nearly 1.5 times its size; at the time of its discovery, Kepler-7b was the second most diffuse planet known, surpassed only by WASP-17b. It orbits its host star every five days at a distance of approximately 0.06 AU. Kepler-7b was announced at a meeting of the American Astronomical Society on January 4, 2010. It is the first extrasolar planet to have a crude map of cloud coverage.
Kepler-22b is an exoplanet orbiting within the habitable zone of the Sun-like star Kepler-22. It is located about 640 light-years from Earth in the constellation of Cygnus. It was discovered by NASA's Kepler Space Telescope in December 2011 and was the first known transiting planet to orbit within the habitable zone of a Sun-like star, where liquid water could exist on the planet's surface. Kepler-22 is too dim to be seen with the naked eye.
Lisa Kaltenegger is an Austrian astronomer specialising in the modeling and characterization of exoplanets and the search for life. On July 1, 2014, she was appointed Associate Professor of Astronomy at Cornell University. Previously, she held a joint position at the Max Planck Institute for Astronomy in Heidelberg where she was the Emmy Noether Research Group Leader for the "Super-Earths and Life" group, and at the Center for Astrophysics | Harvard & Smithsonian in Cambridge, MA. She was appointed Lecturer in 2008 at Harvard University and 2011 at University of Heidelberg.
William J. (Bill) Borucki is a space scientist who worked at the NASA Ames Research Center. Upon joining NASA in 1962, Borucki joined the group conducting research on the heat shield for Apollo program spacecraft. He later turned his attention to the optical efficiency of lightning strikes in the atmospheres of planets, investigating the propensity that these lightning strikes could create molecules that would later become the precursors for life. Subsequently, Borucki's attention turned to extrasolar planets and their detection, particularly through the transit method. In light of this work, Borucki was named the principal investigator for NASA's Kepler space telescope mission, launched on March 7, 2009 and dedicated to a transit-based search for habitable planets. In 2013, Borucki was awarded the United States National Academy of Sciences's Henry Draper Medal for his work with Kepler. In 2015 he received the Shaw Prize in Astronomy.
Kepler-62f is a super-Earth exoplanet orbiting within the habitable zone of the star Kepler-62, the outermost of five such planets discovered around the star by NASA's Kepler space telescope. It is located about 982 light-years from Earth in the constellation of Lyra.
Kepler-438b is a confirmed near-Earth-sized exoplanet. It is likely rocky. It orbits on the inner edge of the habitable zone of a red dwarf, Kepler-438, about 460.2 light-years from Earth in the constellation Lyra. It receives 1.4 times our solar flux. The planet was discovered by NASA's Kepler spacecraft using the transit method, in which the dimming effect that a planet causes as it crosses in front of its star is measured. NASA announced the confirmation of the exoplanet on 6 January 2015.
The Nexus for Exoplanet System Science (NExSS) initiative is a National Aeronautics and Space Administration (NASA) virtual institute designed to foster interdisciplinary collaboration in the search for life on exoplanets. Led by the Ames Research Center, the NASA Exoplanet Science Institute, and the Goddard Institute for Space Studies, NExSS will help organize the search for life on exoplanets from participating research teams and acquire new knowledge about exoplanets and extrasolar planetary systems.
Kepler-452b is a super-Earth exoplanet orbiting within the inner edge of the habitable zone of the sun-like star Kepler-452 and is the only planet in the system discovered by the Kepler space telescope. It is located about 1,400 light-years (430 pc) from Earth in the constellation of Cygnus.
Sarah Ballard is an American astronomer who is a professor at the University of Florida. She has been a Torres Fellow at the Massachusetts Institute of Technology, a L'Oreal Fellow, and a NASA Carl Sagan Fellow.
Kepler-1229b is a confirmed super-Earth exoplanet, likely rocky, orbiting within the habitable zone of the red dwarf Kepler-1229, located about 870 light years from Earth in the constellation of Cygnus. It was discovered in 2016 by the Kepler space telescope. The exoplanet was found by using the transit method, in which the dimming effect that a planet causes as it crosses in front of its star is measured.
Elisa Victoria Quintana is a scientist working in the field of astronomy and planetary science at NASA Goddard Space Flight Center. Her research focuses the detection and characterization of exoplanets in addition to studying how they form. She is best known for the detection of Kepler 186f, the first Earth-sized planet found in the habitable zone of a star other than the Sun.
Aomawa L. Shields is an associate professor of physics and astronomy at UC Irvine. Her research is focused on exploring the climate and habitability of small exoplanets, using data from observatories including NASA's Kepler space telescope. Shields was a 2015 TED Fellow, and is active in science communication and outreach. She develops interactive workshops to encourage self-esteem and teach about astronomy, combines her training in theater and her career in astronomy.
Kepler-1625 is a 14th-magnitude solar-mass star located in the constellation of Cygnus approximately 7,200 light-years away. Its mass is within 5% of that of the Sun, but its radius is approximately 70% larger reflecting its more evolved state. A candidate gas giant exoplanet was detected by the Kepler Mission around the star in 2015, which was later validated as a real planet to >99% confidence in 2016. In 2018, the Hunt for Exomoons with Kepler project reported evidence for a Neptune-sized exomoon around this planet, based on observations from NASA’s Kepler mission and the Hubble Space Telescope. Subsequently, the evidence for and reality of this exomoon candidate has been subject to debate.
Jessie Christiansen is an Australian astrophysicist who is the Chief Scientist of the NASA Exoplanet Science Institute at the California Institute of Technology (Caltech). She won the 2018 NASA Exceptional Engineering Achievement Medal for her work on the Kepler planet sample.
WASP-39b, officially named Bocaprins, is a "hot Jupiter" extrasolar planet discovered in February 2011 by the WASP project, notable for containing a substantial amount of water in its atmosphere. In addition WASP-39b was the first exoplanet found to contain carbon dioxide in its atmosphere, and likewise for sulfur dioxide.
Kepler-1658b is a hot Jupiter, a type of gas giant exoplanet, that orbits an F-type star called Kepler 1658, located about 2629 light-years away from the Solar System. It is the first planet identified by the Kepler space telescope after its launch in 2009, but later ruled out as false alarm since its transit could not be confirmed. A study published in 2019 established it as a planet, describing it as "the closest known planet in terms of orbital period to an evolved star." Analysis of the Transiting Exoplanet Survey Satellite (TESS) data in 2022 showed that it is gradually spiraling into its star.
LHS 475 b is a terrestrial planet orbiting the star LHS 475 which is about 40.7 light years away, in the constellation of Octans. It was the first extrasolar planet to be confirmed by the James Webb Space Telescope. It completes an orbit every 2 days and is 99% the diameter of Earth. It is also one of the most similar-to-Earth exoplanets discovered, in terms of radius.
