In recent years, the discovery of new exoplanets has rocked the world of astronomy, bringing deeper insight into the potential for life beyond Earth. Extrasolar planets, or exoplanets, are planets that are outside our solar system. Since the first discovery of exoplanets in the early 1990s, more than 5,000 exoplanets have been identified, thanks to the development of advanced telescope technology. One of the most striking achievements is the use of the mission by the Kepler space telescope and TESS (Transiting Exoplanet Survey Satellite). Both missions use the transit method to detect exoplanets. This method observes a decrease in a star’s brightness as a planet passes in front of it, providing accurate data about the size and orbit of the planet. These discoveries have opened up new possibilities, including planets in the habitable zone, places where water can exist in liquid form. One of the newest exoplanets to attract attention is TOI-700 d, located in the constellation Dorado. This planet is in the habitable zone of its star and is similar in size to Earth. This discovery is a step forward in the search for life beyond our planet, giving hope that there are other places in the universe where we might find life. Additionally, the discovery of exoplanets with atmospheres, such as WASP-121b, provides insight into the chemical composition, temperature, and possible geological processes on other planets. WASP-121b is an evolved hot gas planet, with an atmosphere rich in metals. Spectral analysis shows that the planet is likely to experience extreme weather phenomena, improving our understanding of atmospheric dynamics beyond Earth. New technologies are also fueling deeper and faster discovery. New telescopes such as the James Webb Space Telescope (JWST) offer unprecedented observation capabilities, empowering astronomers to study the atmospheric characteristics of exoplanets in greater detail. JWST, which was launched in late 2021, is expected to be able to detect signs of life, such as life-related gases, in exoplanet atmospheres. Therefore, the growing number of exoplanet discoveries not only sheds light on the diversity of planetary systems in the universe but also paves the way for further research. The ongoing scientific debate regarding the origins and evolution of the planet has also attracted public attention and fueled curiosity about the universe. With continued technological developments and ever-deepening research, the world of astronomy is gearing up for a new age of space exploration. Society is now increasingly connected to the discoveries that occur, looking forward to the latest news and information about exoplanets that can revolutionize our understanding of the universe.
