atmosphere

SwRI is studying how Saturn's largest moon maintains its dense atmosphere. Scientists think Titan's core is covered in layers of ice and a subsurface liquid ocean. New experiments show that nitrogen and methane gases produced by organic matter in the core seep to the surface, regularly renewing the atmosphere. Credit: Southwest Research Institute

Scientists decipher Titan's dense atmosphere – new discoveries about the sources of nitrogen and methane

New research suggests that nitrogen and methane seep from Titan's rocky core to the surface, helping to maintain its dense atmosphere. The findings could shed light on the planet's internal chemistry.

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.
