While the presence of these molecules is not proof of ancient life on Mars, scientists say it shows we could detect chemical ...

More than 3 billion years ago, Mars was a very different place. It wasn't the rusty, dead seeming world we see today. Instead, lakes, rivers, and deltas likely covered much of the planet's surface.

Curiosity found large organic molecules in a 2013 Mars rock sample. These fragments suggest Mars had the right chemistry for ...

Methane might be a hazard to human health, but it is also powerful greenhouse gas. While it has a much shorter lifespan in the atmosphere than carbon dioxide (CO2), methane is much better at trapping ...

Methane gas is a possible sign of life ... 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 ...

The same greenhouse gasses that pollute the Earth would be key to warming Mars ... greenhouse gas-producing factories that generate large quantities of chlorofluorocarbons, methane, and carbon ...
