NASA Launches Pandora Telescope To Overcome Key Hurdle In Exoplanet Discovery

NASA has taken a groundbreaking leap in the pursuit of discovering habitable worlds beyond our planet with the launch of the Pandora telescope. This innovative mission is set to revolutionize the study of exoplanet atmospheres, building upon the remarkable work of the James Webb Space Telescope (JWST). For years, astronomers have employed a technique to analyze the atmospheres of distant planets by observing the starlight that filters through them as they orbit their host stars.

However, this method has been marred by a significant flaw, known as the “transit light source effect.” According to research published in Science, this phenomenon occurs when starspots – cooler, active regions on stars – interfere with transit measurements, leading to inaccurate readings. A team of scientists, including astrophysicist Mark Giampapa and former Ph. D. student Benjamin V. Rackham, have been at the forefront of addressing this issue.

Their studies, published in 2018 and 2019, highlighted the impact of starspots and magnetically active stellar regions on exoplanet measurements. As noted by Science, these findings predicted that the JWST, launched in 2021, would face significant challenges in reaching its full potential due to the complexities of starlight.
