Methane

In some ways, the most Earth-like world in our solar system is Saturn’s largest moon, Titan. And now, astronomers from NASA JPL and Arizona State University have used years of Cassini data to construct the first global map of Titan.

The burning of agricultural waste and the methane that's burped up by cows are two major sources of greenhouse gases. An experimental new type of animal feed, however, is aimed at reducing both the burning and the burps.

A Russian expedition through the East Siberian Sea has uncovered fountains of methane bubbles in concentrations never seen before.

The belches of cattle around the world are a huge source of methane emissions, but a sprinkling of seaweed in their diets could change that.

Livestock like sheep and cows are responsible for huge amounts of methane emissions. Now, an international team of researchers has analyzed the gut microbes of different sheep and found clues that may help us curb the problem.

With oceans of liquid methane, Saturn’s moon Titan is one of the most fascinating places in the solar system. To better understand this weird world, scientists recreated Titan’s alien oceans in the lab, producing new types of crystals that don’t occur naturally on Earth but may be common on Titan.

The latest methane measurements on Mars to generate some intrigue among planetary scientists stems from the largest ever reading of the gas taken during the Curiosity rover's seven-year mission, which again raises the prospect of microbial life existing at some time, some place on the Red Planet.

A new study has independently measured methane emissions from a number of ammonia fertilizer plants. The startling results suggest methane emissions are 100 times higher than industry estimates, and three times higher than the EPA’s estimate for all industry methane emissions in the United States.​

The ExoMars Trace Gas Orbiter (TGO) has made a map of the distribution of watery minerals in the Martian surface, studied how the global dust storm affected the atmosphere, and intriguingly found very little methane, which calls into question the results of a study just last week.

Scientists in Europe have made an exciting breakthrough in the effort to limit methane seeping into the atmosphere, isolating a previously unknown bacterium that appears to have a ravenous appetite for the atmospheric trace gas.​

The mystery of methane on Mars has been wafting around for decades. Now, using data gathered by the ESA's Mars Express orbiter and NASA's Curiosity rover on the ground, a new study has not only confirmed that the gas is there, but identified its likely source.

Titan, the largest moon of Saturn, is a surprisingly dynamic world. Summer was due to hit its northern hemisphere in 2016, but strangely it didn’t seem to arrive as expected. Now, astronomers have analyzed Cassini images and found evidence of rainfall, indicating that finally, summer is coming.
