NASA’s Chandra Mission is delving into the habitability of exoplanets by studying stars near the Sun to determine if they could support life. By using X-ray data from NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton, astronomers are assessing whether exoplanets receive harmful radiation from the stars they orbit.
The research aims to identify planets within the habitable zones of nearby stars that could potentially harbor liquid water on their surfaces. Factors such as the amount of X-rays and ultraviolet light a planet receives play a crucial role in determining its suitability for life. Brighter and more energetic X-rays can have detrimental effects on a planet’s atmosphere.
By analyzing almost 10 days of Chandra observations and 26 days of XMM observations, researchers examined 57 nearby stars to understand their X-ray behavior. The study focused on the brightness and energy of X-rays emitted by stars, as well as how these emissions fluctuate over time. This information is vital for identifying stars with hospitable conditions for potential life forms to thrive.
The results of this research were presented at the 244th meeting of the American Astronomical Society by Breanna Binder from California State Polytechnic University in Pomona. Most of the stars studied had giant planets similar to Jupiter, Saturn, or Neptune, with only a few potential Earth-sized candidates.
NASA’s Marshall Space Flight Center oversees the Chandra program, while the Smithsonian Astrophysical Observatory’s Chandra X-ray Center manages scientific operations. This research will help guide future observations with advanced telescopes in space and on the ground to capture the first images of Earth-like planets.
