Are we alone in the universe—or are we on the edge of discovering our cosmic neighbors?
In 2023, NASA’s James Webb Space Telescope detected a startling chemical signature in the atmosphere of K2-18b, a planet 120 light-years from Earth. Alongside water vapor and methane, the planet may harbor dimethyl sulfide (DMS)—a molecule linked to biological life on Earth.
In Alien Signals?, author Dinesh Aswani takes readers on a journey across the frontiers of space, science, and speculation. Through 10 engaging chapters, this book explores:
- What makes K2-18b so unique among thousands of discovered exoplanets
- How scientists detect atmospheric biosignatures across light-years
- The life-or-no-life debate surrounding DMS and alien chemistry
- The revolutionary role of the James Webb Space Telescope (JWST)
- Other exoplanets that may harbor life—and how we plan to find it
- The philosophical, scientific, and spiritual implications of discovering extraterrestrial life
📖 Perfect for fans of astrobiology, space science, astronomy, and cosmic mystery.
