**Who / What**
Terraforming is a hypothetical planetary engineering process involving the deliberate modification of a celestial body's environment to resemble Earth. Its goal is to make other planets, moons, or similar bodies habitable for human life by altering factors such as atmosphere, temperature, and surface conditions.
**Background & History**
The concept originated from both science fiction and scientific thought, with astronomer Carl Sagan's 1961 proposal for engineering Venus considered one of the first serious accounts. Terraforming has since been explored in theoretical studies and popular media, evolving as a topic of scientific speculation and futurism.
**Why Notable**
Terraforming is significant for its ambitious vision of expanding human civilization beyond Earth, addressing long-term survival and space colonization. It represents a major theme in astrobiology and planetary science, inspiring research into climate manipulation and ecosystem creation. The concept also captures public imagination through its frequent portrayal in science fiction.
**In the News**
Interest in terraforming remains relevant due to ongoing space exploration efforts and discussions about Mars colonization. Recent advances in climate science and biotechnology continue to inform theoretical models, keeping the concept in scientific and public discourse.
