What is Sara Seager known for?
She is known particularly for her foundational ideas on exoplanet atmospheres, which helped define the field, and includes work that led to the first detection of an exoplanet atmosphere. Her work broadly extends to exoplanet interiors, biosignature gases, and space missions.
What did Sara Seager study?
Biographical Sketch. Sara Seager is the Class of 1941 Professor of Planetary Science, Professor of Physics, and Professor of Aeronautics and Astronautics at the Massachusetts Institute of Technology. She received her B.Sc. in mathematics and physics from the University of Toronto in 1994.
Are there any confirmed exoplanets?
In a milestone for astronomy – and possibly the search for extraterrestrial life – NASA’s Jet Propulsion Laboratory confirmed there are now 5,000 known planets beyond our solar system. These so-called exoplanets include rocky worlds roughly the size of Earth, gas giants larger than Jupiter and “mini-Neptunes.”
Are there photos of exoplanets?
Of the thousands of exoplanets discovered so far orbiting distant stars, earthly astronomers have captured direct images of only a very few. In each of these images, only one planet can be seen. Now astronomers say they’ve acquired a first-ever direct image of two giant exoplanets, orbiting a sunlike star.
What did Sara Seager invent?
Her research has introduced many new ideas to the field of exoplanet characterization, including work that led to the first detection of an exoplanet atmosphere. She was part of a team that co-discovered the first detection of light emitted from an exoplanet and the first spectrum of an exoplanet.
Can James Webb see exoplanets?
The James Webb Space Telescope will map the atmosphere of exoplanets. Exoplanets, planets that orbit stars other than the sun, are found at distances very far from Earth. For example, the closest exoplanet to us, Proxima Centauri b, is 4.2 light-years away, or 265,000 times the distance between the Earth and the sun.
How old is Sara Seager?

What is the biggest exoplanet?
The largest planet ever discovered is also one of the strangest and theoretically should not even exist, scientists say. Dubbed TrES-4, the planet is about 1.7 times the size of Jupiter and belongs to a small subclass of “puffy” planets that have extremely low densities.
Can Hubble see exoplanets?
Thanks to its stability and ability to take high-contrast images, Hubble was the first to capture an exoplanet in visible light. Astronomers had long suspected that a planet orbits the bright star Fomalhaut after observing suspicious features in the debris disk that surrounds the star.
