James Webb Telescope to Study TRAPPIST-1 System
International Team to Use Telescope to Measure Atmospheric Composition of Exoplanets
An international team of researchers is using NASA's James Webb Space Telescope to measure the atmospheric composition of the seven rocky exoplanets orbiting the TRAPPIST-1 star. The TRAPPIST-1 system is located just 40 light-years from Earth, and the planets are all within the habitable zone of their star, meaning that they could potentially support liquid water on their surfaces.
The James Webb Space Telescope is the most powerful telescope ever built, and it is able to detect the faint light emitted by exoplanets. By measuring the wavelengths of this light, astronomers can determine the composition of the planets' atmospheres.
The researchers will be looking for signs of water vapor, carbon dioxide, and other molecules that could indicate the presence of life. If they find these molecules, it would be a major step forward in our search for extraterrestrial life.
The James Webb Space Telescope is expected to begin its science operations in mid-2022. The TRAPPIST-1 system is one of the first targets that the telescope will observe, and the results of this study could have a major impact on our understanding of the potential for life beyond Earth.
