This artistic concept shows what the extrasolar planet 55 Cancri e might look like. The star, also called Janssen, is a super-Earth, a rocky planet significantly larger than Earth but smaller than Neptune, orbiting its star at a distance of only 1.4 million miles (0.015 AU), completing a full orbit in less than 18 hours. (The planet Mercury is 25 times farther from the Sun compared to 55 Cancri e from its star). The system, which also includes four large gaseous planets, is located about 41 light-years from Earth, in the constellation Cancer. Credit: NASA, ESA, CSA, Ralph Crawford (STScI)

Creating acid rain: Acidic gases (sulfur dioxide and nitrogen oxides) are emitted from factories and vehicles into the atmosphere, where they are carried by the wind until they reach clouds or water-rich fog. The gases then dissolve in water and produce acid rain that destroys vegetation and pollutes rivers. And the lakes and crumbled stone buildings.
