... lost to space, allowing for longer-chain chemical reactions to take place involving carbon or nitrogen. Tentative fingerprints of methane, along with water ice have potentially been observed on Ultima by LEISA, say Stern and colleagues in their...
... that are studied more readily. So far, a number of gases such as sodium (Na), potassium (K), carbon monoxide (CO), water (H2O), methane (CH4), and titanium oxide (TiO) have been identified in the atmospheres of giant exoplanets, but when it comes...
... and dotted with hydrocarbons, Titan’s atmosphere is made mostly of nitrogen, like Earth’s, with a hint of methane (CH4). 3.8 to 2.5 billion years ago, methane filled Earth’s air instead of oxygen, so if conditions on Titan today are similar to those...
...hugging the planet and has uncovered clues to help to solve the methane mystery on Mars. But now it could be about to determine... new class of gas discovered since the claimed observation of methane by ESA's Mars Express in 2004, which motivated the ...
... time. Whereas MAVEN will study Mars' upper atmosphere, MOM carries different instruments, include a sensor to detect methane, a chemical that could mark the presence of microbial life. Aside from science, a major factor in the Asian...
... Greenhouse Gases Observing Satellite (GOSAT) was launched in 2009 as the world’s first satellite to monitor CO2 and methane (CH4) levels. The satellite was named Ibuki, meaning “breath” in Japanese. The satellite was developed jointly...
