EARTH.COM - The search for extraterrestrial life has captivated our imaginations for centuries. Now, a study from the University of California, Riverside (UCR) suggests a tantalizing possibility: we may be able to detect alien activity and civilizations by identifying artificial greenhouse gases they use to terraform planets.
What is terraforming?
Terraforming, a concept popular in science fiction, involves transforming a planet’s environment to make it hospitable for life as we know it. This process aims to alter various aspects of a planet to create conditions that are suitable for human habitation or for Earth-like organisms to thrive.
Altering the atmosphere
One of the primary goals of terraforming is to modify the planet’s atmosphere. This could mean increasing or decreasing the levels of certain gases to create a breathable environment.
