Scientists using the James Webb Space Telescope have detected strong evidence of water vapor in the atmosphere of TRAPPIST-1e, a rocky exoplanet located approximately 40 light-years from Earth. The discovery, published in the journal Nature Astronomy, marks the first time water has been identified on a planet within the habitable zone of its star. Researchers analyzed infrared spectra captured by the telescope's near-infrared spectrograph and found clear signatures of water molecules at concentrations similar to those found in Earth's upper atmosphere. While the planet's extreme temperatures and radiation environment make it unlikely to support life as we know it, the finding demonstrates that rocky worlds can retain water over billions of years. This brings scientists closer to answering one of astronomy's most fundamental questions.
