... of Saturn’s moon Enceladus, suggested to have a global ocean and likely hydrothermal activity. A plume of ice particles, water vapour and organic molecules sprays from fractures in the moon's south polar region. This remarkable discovery of geologic...
.... The TGO also carries scientific instruments of its own to detect and study trace gases, such as methane, water vapour, nitrogen oxides, and acetylene that are present in very small amounts (less than 1%) in the Martian atmosphere...
... station to make daily observations for several years to come, on the levels of aerosols, ozone, nitrogen dioxide and water vapour in the stratosphere and troposphere high above Earth. The Dragon craft is also carrying research materials that...
... them from sinking or forming cloud layers, and making them easier to detect. Well-known ingredients such as water vapour, carbon dioxide and methane will be searched for with ARIEL’s metre-class telescope that looks at the...
... shell, plans to visit the ice world to search for life were pushed to the forefront. And when water-vapour plumes shooting out from the bottom of canyons on the moon’s south pole were discovered by the Cassini...
.... "We expected an atmosphere strongly enriched in heavier elements like oxygen and carbon which are forming abundant water vapour and methane gas, similar to what we see on Neptune,” said Benneke. "Instead, we found an atmosphere that is so poor...
