NEW DELHI: Dr Lisa Kaltenegger, a former Nasa mission reviewer and current professor, has released a fascinating new book titled “The Worlds That Shook Science,” where she delves into the variety of exoplanets in our galaxy that may host life. This book arrives during what Dr Kaltenegger describes as a “new golden era of exploration” in astronomy, driven by significant breakthroughs over the past three decades.
As per a Daily Mail report, the book details dozens of exoplanets that have been classified as potentially habitable or Earth-like.These include a range of exotic environments from water worlds governed by octopus-like creatures to dark planets where the sun never rises, and even hostile environments with molten rock raining from the sky. According to Dr Kaltenegger, 70 of these planets have just the right ingredients for life to exist, despite being thousands of light-years away from Earth.
Dr Kaltenegger highlights the importance of the James Webb Space Telescope (JWST) in this exploration. The JWST’s powerful capabilities allow it to capture light from these distant worlds and analyze their atmospheric compositions—a crucial step in assessing their potential for supporting life.
“The JWST is the first telescope capable of capturing just enough light with its 21.3-foot mirror to explore the chemical composition of the atmosphere of other rocky worlds,” D. Kaltenegger explained to Big Think. She adds that understanding the chemical makeup encoded in the light can provide insights into the existence of extraterrestrial life.
Despite the technical challenges and vast distances involved, Dr Kaltenegger remains hopeful about the search for alien life. “I hope to convey just how difficult the search for alien life will be,” she writes. “We might not even recognize it when it is staring us in the face.”
This pioneering book not only expands our knowledge of the cosmos but also ignites imagination about what kinds of life forms might exist beyond our solar system.
