Dr Lisa Kaltenegger, a former Nasa mission reviewer and current professor, has recently published a riveting new book titled “The Worlds That Shook Science.” In this book, she delves into the various exoplanets in our galaxy that could potentially support life. Dr Kaltenegger describes this as a “new golden era of exploration” in astronomy, fueled by remarkable advancements in the field over the past three decades.
According to a Daily Mail report, the book discusses numerous exoplanets that have been identified as potentially habitable or Earth-like. These planets offer a range of fascinating environments, such as water worlds inhabited by octopus-like creatures, dark planets where the sun never rises, and hostile environments where molten rock falls from the sky. Dr Kaltenegger notes that around 70 of these planets have the necessary conditions for life to exist, despite being located thousands of light-years away from Earth.
Dr Kaltenegger emphasizes the importance of the James Webb Space Telescope (JWST) in this exploration. The JWST’s advanced capabilities enable it to capture light from distant worlds and analyze their atmospheric compositions, which is a crucial step in determining their potential to support life. She explains to Big Think that the JWST, with its 21.3-foot mirror, is the first telescope capable of collecting sufficient light to explore the chemical composition of other rocky worlds, providing valuable insights into the existence of extraterrestrial life.
Despite facing immense technical challenges and vast distances involved in searching for alien life, Dr Kaltenegger remains optimistic about her findings. She highlights how difficult it is to identify alien life forms but expresses hope that we will continue making progress in this area. “We might not even recognize it when it is staring us in the face,” she writes in her book.
