New planets in the Milky Way Galaxy always attract the attention of scientists and astronomers. Improved space observation technology allows researchers to discover exoplanets in a more effective way. Recently, a team of astronomers succeeded in identifying a planet called Kepler-1649c, which is located 300 light years from Earth in the constellation Lyra. Kepler-1649c is a rocky planet that is about 1.06 times the diameter of Earth. The planet rotates in the habitable zone of its star, meaning it is ideally positioned to support the existence of liquid water. This discovery suggests the possibility of conditions that support life. Scientists use the transit method, by monitoring changes in a star’s light as a planet passes in front of its star. Data from the Kepler Telescope provides deep insight into the planet’s atmosphere. Preliminary analysis shows the possible presence of gases that support life. Although there is no definitive proof yet, further research with advanced telescopes such as the James Webb Space Telescope is expected to provide more accurate information. Another notable discovery is the planet TOI-700d, located in the TOI-700 star system. This planet was discovered in 2020 and is included in the super-Earth category with a size larger than Earth. TOI-700d is in the habitable zone, opening up opportunities for research into the possibility of life. The existence of a hypothetical atmosphere on this planet can be further investigated through spectroscopes. Exoplanets also show astonishing diversity. In addition to rocky planets, astronomers have discovered gas giant planets, such as WASP-121b. This planet is famous for its very high temperatures, reaching 3,200 degrees Celsius. This discovery challenges our understanding of planet formation and evolution. Breakthrough technologies such as the Transiting Exoplanet Survey Satellite (TESS) Telescope and other missions from NASA continue to increase our capacity to detect new planets. TESS, launched in 2018, has successfully discovered thousands of planet candidates, increasing the chances of finding planets that might support life. A collaborative approach between astronomers around the world is accelerating exploration of our galaxy. Research and data collected from multiple international telescopes are being combined to provide a deeper understanding of exoplanet climates and atmospheres. For example, early studies of the presence of water molecules in the atmospheres of new planets give hope that some planets may have favorable conditions for life. Ultimately, the discovery of new planets in the Milky Way Galaxy enriches our knowledge of the universe, sparks curiosity, and inspires future generations. Research continues to uncover the secrets hidden in space, waiting to uncover further mysteries about life beyond Earth.
