# Mars volcanic activity evidence found by scientists

*New research suggests an inactive magma chamber may lie beneath the planet's surface.*

**Scores for the source reporting** (0-100, assessing the original journalism this article was written from, not this write-up): 

- Trust 78 of 100, higher is better. Trust 78: multiple named scientists, a cited article, and independent outlets corroborate volcanic activity evidence.
- Craft 77 of 100, higher is better. Critic 77: explains significance, separates fact from speculation, includes specific names and dates, and is clearly written.
- Hype 35 of 100, lower is better. Hype 35: language is lively but not exaggerated; headlines modestly reflect the digests' content.

Scored by MediaBias News; method at https://mediabias.news/methodology.

**The short version**

- A Russian spectrometer on the TGO spacecraft detected evidence of volcanism on Mars.
- Scientists suggest an inactive magma chamber may be present beneath the Martian surface.
- Hydrogen chloride emissions on Mars are linked to hot magma below the surface.
- The rate of Mars' volcanic eruptions has decreased substantially over billions of years.

Evidence of volcanism on Mars has been detected by scientists, suggesting the planet may not be geologically dead. A Russian ACS spectrometer on the TGO spacecraft found signs of volcanic activity, according to Interfax. Researchers also believe an inactive magma chamber could be located beneath the planet's surface, as reported by glasistre.hr. An international team attributes hydrogen chloride emissions on Mars to hot magma beneath the surface, according to the Owensboro Messenger-Inquirer.

## Disagreement on eruption timeline

France24, citing AFP Daniel Mège, states that Mars' volcanic eruption rate has declined over two billion years, with the most recent eruptions occurring tens of millions of years ago. IFLScience suggests that after at least two million years without an eruption, Martian volcanism might be considered to be on a brief nap.

## What the coverage left out

None of the left-rated digests mention the specific finding by the Russian ACS spectrometer on the TGO spacecraft. None of the centre-rated digests mention the hydrogen chloride emissions or the inactive magma chamber possibility. None of the right-rated digests mention the specific timeline of eruption decline over billions of years or the possibility of subsoil water pockets.

## Who covered it

Shares of the 72 covering outlets with a published leaning rating:

- Left: 29% (20)
- Centre: 40% (31)
- Right: 31% (21)

54 of 126 covering outlets carried no usable leaning rating and were excluded from those percentages. Coverage measured 2026-11-06T18:00:15.168143+00:00.

## How the sides framed it

### Left

- The left-rated reports highlighted the potential for volcanic activity on Mars and its implications for life. IFLScience noted that Martian volcanoes may not be dead but merely sleeping, questioning if an eruption could occur. In.gr reported that signs of volcanic activity were recorded for the first time on Mars, rekindling hopes for life and suggesting that volcanic heat could create hospitable pockets of moist water in the subsoil.

### Centre

- France24's report focused on the historical decline of volcanic activity on Mars. It cited Daniel Mège, who explained that the eruption rate has been falling for two billion years, with the most recent eruptions occurring tens of millions of years ago, suggesting Mars is volcanically falling asleep.

### Right

- The right-rated reports focused on the discovery of volcanic activity and its potential implications. Interfax.ru reported that a Russian spectrometer found evidence of volcanicism on Mars, suggesting modern Mars might still be volcanically active. The Owensboro Messenger-Inquirer stated that an international research team believes the release of hydrogen chloride comes from hot magma beneath the surface.

## Questions

**What evidence suggests volcanism on Mars?**

A Russian ACS spectrometer on the TGO spacecraft detected evidence of volcanic activity on Mars. Additionally, hydrogen chloride emissions have been linked by scientists to hot magma beneath the planet's surface.

**Could there be an inactive magma chamber on Mars?**

Yes, scientists suggest that an inactive magma chamber may be hiding beneath the surface of Mars, according to new research. This finding is based on traces of volcanic activity discovered.

**How has Mars' volcanic activity changed over time?**

The rate of volcanic eruptions on Mars has been falling significantly over billions of years. While the most recent eruptions occurred tens of millions of years ago, scientists suggest the planet may be in a 'sleeping mode' rather than being geologically dead.
