But we won't know for sure until we go digging for it. Hints of methane on Mars go back all the way to the Mariner missions of the 1970s. But in 2013, NASA's Curiosity rover saw methane levels ...

The detection of life beyond Earth would be one of the most profound discoveries in the history of science. The Milky Way ...

“Bottom line is that we have no detection of methane so far,” Chris Webster, a Mars scientist at the Jet Propulsion Laboratory in Pasadena, California, told Nature. The findings don’t completely rule ...

methane, and carbon dioxide, which would then trap solar radiation and help build a thicker Martian atmosphere. Whether the material for constructing the factories could be shipped to Mars or made ...

We have spotted tantalising glimpses of methane on Mars a few times over the years, but it has been difficult to confirm the detections with other instruments. In 2019, Curiosity detected the ...

That’s why a two-month-long burst of methane on Mars, announced at the fall meeting of the American Geophysical Union (coincidentally, the same day the PLOS Biology article ran), generated such ...

The search for life beyond Earth has led scientists to explore many suggestive mysteries, from plumes of methane on Mars to clouds of phosphine gas on Venus. But as far as we can tell, Earth’s ...
