Cosmic Musings lecture series presented by United Airlines.



We thought the planets of our solar system were weird worlds, until we began to see the lands harbored by our neighboring stars. Huge Jupiters snuggle so close to their stars that one year lasts days. Other worlds begin their nights with dual sunsets like Star Wars Tatooine or drown in global oceans or seas of magma. Let’s visit worlds more extreme than anything in fiction and ask if any could be called home.

ELIZABETH TASKER is an astrophysicist at the Japan Aerospace Exploration Agency (JAXA), where her research explores the formation of stars and planets using computer modelling. Originally British, she completed her doctorate at the University of Oxford before spending five years in North America at Columbia University and the University of Florida in the USA and McMaster University in Canada. She moved to Japan in 2011 and continues to look forward to the day when the Japanese canteen menu is less confusing than her research. Her popular science book on planet formation and exoplanets, The Planet Factory, was published by Bloomsbury Sigma last November. Elizabeth can be found on twitter and her website (@girlandkat, and also discussing exoplanets in various media, including the NASA's NExSS “Many Worlds” blog, .



The Planet Factory
Exoplanets and the Search for a Second Earth
An informative and entertaining read, Elizabeth Tasker's The Planet Factory takes the reader to the cutting edge of the ongoing search for worlds like our own, and the hints of life elsewhere in the cosmos.
