Dr. Natalie Batalha’s STEM-Talk interview was so contagious that Dawn Kernagis said it made her dream of returning to school to get a second graduate degree in astronomy.
“Hearing Natalie talk about her research had all of us in the STEM-Talk studio buzzing,” said Dawn, the podcast’s co-host.
Natalie is an astrophysicist and the project scientist for NASA’s Kepler Mission, a space observatory launched by NASA to discover Earth-sized planets orbiting other stars. She sat down with Dawn and veteran astronaut and IHMC senior research scientist Tom Jones for episode 33 of STEM-Talk.
As one of the original co-investigators of the Kepler Mission, Natalie has been a leader in using the telescope to discover exoplanets, which are planets that orbit stars other than our own sun. Natalie has been involved in the Kepler Mission since the proposal stage and has helped identify more than 150,000 stars that are monitored by the telescope.
She holds a bachelor’s degree in physics from The University of California Berkeley, and a doctoral degree in astrophysics from UC Santa Cruz. She taught physics and astronomy for 10 years at San Jose State University before joining the Space Sciences Division of the NASA Ames Research Center, which is located in California’s Silicon Valley.
In 2011, Natalie received a NASA Public Service Medal for her vision in communicating Kepler’s science to the public, and also for her outstanding leadership in coordinating the Kepler science team. That same year Natalie also headed up the analysis that led to the discovery of Kepler 10b, the first confirmed rocky planet outside our solar system.
She joined the leadership team of a new NASA initiative in 2015, which is dedicated to the search for evidence of life beyond our solar system. Called the Nexus for Exoplanet System Science, the program brings together teams from multiple disciplines to understand the diversity of worlds, and which of those exoplanets are most likely to harbor life.
As if Dawn and the STEM-Talk gang weren't excited enough after talking to Natalie about the search for life beyond our solar system, NASA announced about a month after our interview with Natalie that its Spitzer Space Telescope had revealed the first known system of seven Earth-sized planets around a single star. Three of these planets are firmly located in the habitable zone, the area around the parent star where a rocky planet is most likely to have liquid water.
According to a NASA press release in February, the discovery sets a new record for greatest number of habitable-zone planets found around a single star outside our solar system. All of these seven planets could have liquid water – key to life as we know it – under the right atmospheric conditions, but the chances are highest with the three in the habitable zone.
0:30: Dawn welcomes Ken Ford, IHMC founder and director as well as the chairman of the Double Secret Selection Committee that chooses guests who appear on STEM-Talk. Dawn and Ken then talk about Natalie’s background as an astrophysicist.
4:35: Dawn welcomes her co-host for this episode of STEM-Talk, Tom Jones, and they begin the interview by asking Natalie how she became interested in astronomy.
8:03: Natalie talks about how as an undergrad at Berkeley she met a post-doctoral researcher from Brazil who later became her husband. As a result, she ended up doing her post-doctoral work in Rio de Janeiro.
15:47: Dawn asks Natalie to describe the history of the Kepler mission.
19:00: Tom asks Natalie to describe the difficulty of trying to detect a distant planet.
21:34: Natalie describes how long the Kepler telescope has been in space and provides a summary of its findings.
25:30: Natalie talks about lava worlds, which have oceans larger than the Pacific Ocean, but they’re made of lava, which is why scientists call them lava worlds.
27:30: Dawn asks Natalie about the discovery of Kepler 10b,
