A massive volcano has been hiding in plain sight on Mars, says new research. Not only is its sheer size noteworthy, but the team believes it might also harbor glacial ice that could be critical for further exploration and Martian settlements.

Geologists have shed new light on Earth's built-in thermostat. They say shifting tectonic plates that slowed volcanic activity is likely what caused the extreme ice age that turned the planet into a giant snowball over 700 million years ago.

Using microwave instruments to peer deep beneath the surface of the far side of the Moon, researchers have detected a ‘hotspot’ they say is a large subsurface granite mass, suggesting the Moon is more "Earth-like" than we thought.

The eruption of Tonga’s Hunga Volcano on January 15, 2022, produced a record-breaking amount of lightning. The information gathered about the eruption can be used to better monitor aviation-related hazards arising from these sorts of eruptions.

Monitoring extreme environments requires a sensor continues to work in high temperatures. Now, researchers have developed a piezoelectric sensor that operates reliably at the temperature of erupting mafic lava, the hottest type of lava on Earth.

A new, Earth-sized planet has been discovered only 90 light-years away. In astronomical terms, that’s right next door. Moreover, it may be capable of supporting life thanks to volcanic eruptions caused by the gravitational tug of a nearby planet.

What do medieval monks and volcanic eruptions have in common? According to a team of researchers, chronicles from the 12th and 13th century are helping volcanologists to precisely date ancient eruptions based on descriptions of lunar eclipses.

Researchers have examined tiny time capsules found in the oldest-known crystals in an attempt to settle a question that divides scientists: when did Earth’s tectonic plates begin to move and was it at the time life began on Earth?

After decades of speculation, astronomers have discovered the first direct evidence of volcanic activity on Venus. Radar images of Earth’s “twin” taken just a few months apart reveal a recent eruption.

The analysis of volcanic gases allows scientists to determine what processes are taking place deep within volcanoes. And while big, expensive drones have previously been used to sample those gases, a small consumer model can now do the job.

Mars is usually considered a geologically dead planet, but a new study challenges that idea. Multiple lines of evidence reveals a giant plume of magma is forcing its way up through the mantle and producing seismic activity in one region of the surface.

New analysis of a volcanic eruption off the coast of Tonga earlier this year has revealed the true extent of the massive explosion, and established its plume as the highest on record and the first recorded entering the mesosphere.
