Extrasolar planets, or exoplanets, continue to be objects of research interest for modern astronomy. Recent discoveries obtained from various observatories around the world show that many planets outside our solar system are creating more questions about the possibility of life beyond Earth. One of the most prominent discoveries is the planet TOI-700 d. Located 100 light years from Earth, the planet is Earth-like in size and located in the habitable zone of its star. Research shows that TOI-700 d has the potential to support microbial life, thanks to the presence of liquid water on its surface. The implications of these findings are significant; if life once existed there, then our understanding of biology and the conditions necessary for life could expand. Apart from that, the planet LHS 3844 b also attracts the attention of astronomers. Located 49 light years away, this planet has a surface thought to be made of rock, with extreme temperatures. Although not ideal for life like on Earth, researchers think that a very dense atmosphere may harbor a stable environment. Further research could help us understand how animal life can survive in extreme conditions. Another exoplanet, K2-18 b, shows extraordinary potential due to the presence of molecules important for life, such as water. This discovery implies that other possible planets in the habitable zone may have conditions that support life. With the advent of spectroscopy, scientists can now identify the atmospheric composition of exoplanets, making the search for life more promising. The connection between the discovery of this exoplanet and life beyond Earth cannot be understated. They provide insight into the diversity of life forms that may exist, both in extreme conditions and those similar to those we encounter on Earth. These findings encourage us to reexamine assumptions about the survival capabilities of organisms under different conditions. New telescope technologies, such as TESS and JWST, provide new hope for finding more exoplanets and proving that life exists out there. With these advances, research can become more in-depth and comprehensive, creating a robust scientific framework for examining the possibility of extraterrestrial life. Through these discoveries, the relevance of this research is increasingly important in the context of our understanding of ourselves as a species. A question arises: are we alone in this universe? Each new discovery raises discussions about the philosophy and ethics related to the search for life beyond Earth. The importance of astronomical observations and subsequent research cannot be underestimated, because these discoveries open the way for further research that can change the way we view the existence of life in the universe. Efforts like these not only reveal astronomical facts, but have the potential to explain more about the origins of life itself.
