Graha Theke Grahantare Praner Sandhane by Sujan Sengupta [Hardcover]

Is there life beyond Earth, somewhere in the vast, infinite cosmos? Are we alone in this astonishing universe, or does life exist elsewhere? This eternal curiosity, this timeless question, remains unresolved to this day.

The book "From Planet to Planet: In Search of Life" explores the discovery of exoplanets and the search for Earth-like rocky planets within the habitable zones of stars. It delves into the possibility of life beyond Earth—whether within our solar system or on exoplanets orbiting distant stars.

The book discusses the definition of life, the origin of life on Earth, the evolution and extinction of species in relation to atmospheric and geological changes, and the emergence of intelligent beings. It also provides an extensive overview of humanity’s progress in detecting biosignatures of simple and complex life in space, as well as the search for technological signals from intelligent civilizations.

Additionally, it highlights the imminent threats to life on Earth, including various cosmic and geological dangers. Most importantly, it examines the adverse effects of technological advancements on our planet’s life-supporting environment, raising concerns about the potential extinction of life due to human activities.
