麻豆传媒 — Planet-hunting telescopes have recently taken a huge leap in their ability to find 鈥渆xoplanets,鈥� or planets orbiting other stars. In just the past six months, astronomers have announced the discovery of more than 700 such worlds, bringing the total to more than 1,700. These discoveries include the first Earth-size planet found in what鈥檚 called the habitable zone of a star, where liquid water could exist; the oldest known planet that could support life; and the first rocky 鈥渕ega-Earth,鈥� a planet that鈥檚 much like Earth except that it鈥檚 17 times more massive.

On July 9, 12:00-12:30 pm PDT, three exoplanet hunters discuss the recent uptick in known planets beyond our solar system, consider the next steps in the hunt for habitable worlds, and ponder the odds of finding evidence of life on another planet.

ABOUT THE PARTICIPANTSZACHORY BERTA-THOMPSON - Dr. Berta-Thompson is the Torres Fellow for Exoplanetary Research at the MIT Kavli Institute for Astrophysics and Space Research. He hunts for exoplanets as a member of the MEarth Project, a survey to find small planets orbiting the closest, smallest stars. BRUCE MACINTOSH - Dr. Macintosh is the principal investigator for the Gemini Planet Imager, which searches for planets from the Gemini South telescope. GPI recently snapped its first image, thereby producing the best-ever direct photo of a planet outside our solar system. Dr. Macintosh is also a Professor of Physics at Stanford University and a member of the Kavli Institute for Particle Astrophysics and Cosmology.

MARIE-EVE NAUD - Ms. Naud is the University of Montreal PhD student who led analysis that recently uncovered a previously unknown giant planet using infrared light. The planet, known as GU Pisces b, is one of the most unusual exoplanets found to-date, with a mass 10 times greater than Jupiter's and orbiting its star at 2,000 times the distance between Earth and our sun.
