Astronomers have identified a new exoplanet, designated Kepler-452d, orbiting a sun-like star in the habitable zone, raising hopes for potential life. The planet, slightly larger than Earth, has an atmosphere that could support liquid water. Researchers used advanced space telescopes to confirm its composition and temperature range. The discovery fuels excitement about future missions to explore such worlds. Scientists emphasize that while conditions appear promising, more data is needed to determine habitability. Space agencies worldwide are now prioritizing exoplanet studies, aiming to unlock secrets of distant solar systems and possibly find extraterrestrial life.
