Mysterious gas on Mars suggests magma below

- Researchers report detections of hydrogen chloride gas in Mars's atmosphere near one of the planet's largest volcanoes, in a study published Nov. 4 in Science Advances.
- The gas was found close to the surface, and the authors interpret it as a possible sign that active magma is buried below.
- Coverage from Sky & Telescope and Astronomy Magazine describes the finding as evidence that some form of volcanic activity may still be ongoing on Mars.
Why it matters
If the gas comes from magma, it would point to recent or ongoing volcanic activity on Mars, which bears on the planet's geology and interior heat. The volcanic link is an interpretation of the gas detections, so readers should treat it as a hypothesis.

Something is leaking from the ground near one of Mars’ largest volcanoes, and scientists think it’s a sign that active magma is buried below. In a study published Nov. 4 in Science Advances, researchers report detections of hydrogen chloride (HCl) gas within 6 miles (10…
