Methane in a flash
Martian methane is a hot topic because of its potential origin in biological, as well as geological processes. Observations (Earth-based and from Mars orbit) have found only a small quantity of the greenhouse gas in the atmosphere of Mars — … Continue reading

UV light makes methane from meteorites
Methane gas, which can arise from both biological and geological sources, was detected in the Martian atmosphere by observations from Earth-based telescopes in 2003 and from the Mars Express orbiter (2004). As methane breaks down relatively quickly under Martian conditions, … Continue reading

About that methane….
Methane is a greenhouse gas that on Earth most often has a biological origin, although it can also come from volcanic activity. Because of the biological implications – and because any Martian methane will be destroyed by oxygen in the … Continue reading
