NASA’s Curiosity rover has detected its largest belch of methane on Mars so far, fueling speculation that the robot may have trundled through a cloud of waste gas released by microbial Martians buried deep under the surface.
A team with members from several institutions in the Netherlands has found that the area around a site where a gas explosion occurred in 1965 is still emitting methane gas from the ground into the air.
There is overwhelming evidence that water flowed across and collected on the surface of Mars some three billion to four billion years ago. Yet, most models predict early Mars was too cold for liquid water. What gives?
California Democrats are taking further steps to advance the state's ambitious climate-change agenda, agreeing to regulate methane emissions from landfills and dairy farms for the first time and approving $900 million in spending on environmental programs.
