This article explores microbial life in extreme environments associated with salinity, acidity, alkalinity, high temperature, low temperature, radiation, gravity, and pressure. It also introduces the role of extremophiles in astrobiology followed by brief descriptions of Mars, the moons of Jupiter, and Panspermia. This is the second part of a two-part article. A link is directed to Part 1, which discusses the biomarkers of life; introduces extremophiles in general; and explores life in dry environments.
