Sarah Seager
Definition
Sarah Seager is a planetary scientist who has dedicated her career to studying exoplanets. Exoplanets are planets that orbit stars other than the Sun. Sarah is a professor of planetary science at the Massachusetts Institute of Technology (MIT), and she is also a co-founder of the MIT Exoplanets Research Group.
Sarah has worked on a number of projects to study exoplanets, including:
- Using telescopes to detect exoplanets: Sarah has used telescopes to look for exoplanets around other stars. She has also developed new methods for detecting exoplanets, such as the transit method and the radial velocity method.
- Studying the atmospheres of exoplanets: Sarah has used telescopes to study the atmospheres of exoplanets. She has looked for gases in the atmosphere that could indicate the presence of life, such as oxygen, water, and methane.
- Modelling the formation and evolution of exoplanets: Sarah has developed computer models to study how exoplanets form and evolve. She has also used these models to predict the properties of exoplanets that have not yet been detected.
- Sarah is a passionate advocate for exoplanet research. She believes that exoplanets can teach us a lot about the formation and evolution of our own solar system. She also believes that exoplanets could potentially harbour life, and she is excited to continue the search for exoplanets that could support life.
Sarah is a recipient of the Order of the British Empire (OBE) for her services to science. She is also a fellow of the American Astronomical Society and the American Geophysical Union.

AQA Science Exam Question and Answer
Question:
Explain the pioneering work of Sarah Seager in the field of exoplanet research and its significance for our understanding of extraterrestrial worlds.
Answer:
Sarah Seager has made groundbreaking contributions to the field of exoplanet research, revolutionizing our understanding of distant planets beyond our solar system. As an astrophysicist and planetary scientist, she has focused on characterising exoplanets, particularly those that might be potentially habitable.
Seager's innovative work includes the development of methods to analyze exoplanet atmospheres and identify potential signs of habitability or even life. Her research has contributed to the detection of various exoplanet atmospheres and the identification of key molecules, such as water vapour and methane, which can provide insights into the conditions of these distant worlds.
One of Seager's notable contributions is her work on the concept of "biosignatures," which are potential indicators of life that could be detected in exoplanet atmospheres. By studying the spectral signatures of various molecules, she has helped lay the groundwork for future telescopes that could potentially identify signs of life on distant exoplanets.
Seager's pioneering efforts are of immense significance as they expand our understanding of the diversity of exoplanetary systems and the conditions that might allow for habitability. Her work not only advances astrophysics and planetary science but also ignites our imagination about the possibility of life beyond Earth, pushing the boundaries of our exploration of the cosmos.
