The moon is still geologically active, study suggests

New analysis of data from the Apollo era shows that moonquakes occur close to visible faults, which may matter when setting up a moon base.
Coastal geoscience and engineering is a broad discipline focused on physical processes at the interface of land and sea. Marco Ferraz

Gender inequalities in science won’t self-correct: it’s time for action

For twenty years people had been telling me how lucky I was to be in our field of research because “things” were changing for young women. Twenty years later “things” had not changed.

Nepal earthquake may have ‘unzipped’ fault line, boosting risk of future quake

New research shows the earthquake that struck central Nepal in April this year was only a partial rupture of the fault line, meaning another strong quake could be due in future.
Magnetic traces suggest iron crystals in the innermost core are aligned east-west, rather than north-south. Lachina Publishing Services

Our view of Earth’s inner core is flipped on its side

The planet Earth’s inner core is not a single solid mass but comprised of two layers, and new evidence about the core’s composition from a team of US and Chinese geophysicists suggests that the innermost…

Scientists at work: my other office is on Mars

“All systems go!” I said cautiously with a long sigh of relief. I had approved plans for the first soil analysis that would give humankind clues to the past and future habitability of Mars. One small word…
Volcanism, driven by plate tectonics, built Earth’s atmosphere to make a habitable planet. Simon Redfern/University of Cambridge

How the air we breathe was created by Earth’s tectonic plates

How is it that Earth developed an atmosphere that made the development of life possible? A study published in the journal Nature Geoscience links the origins of Earth’s nitrogen-rich atmosphere to the…

What a crack up: hefty continents got tectonic plates moving

Plate tectonics – the large-scale movement of Earth’s lithosphere or outer layers – started around three billion years ago, but how those movements started was a bit of a mystery – until today. With colleagues…
It’s good that mount Sinabung isn’t a supervolcano. Binsar Bakkara/AP

How Earth’s devastating supervolcanoes erupt

Devastating supervolcanoes can erupt simply due to changes that happen in their giant magma chambers as they slowly cool, according to a new study. This finding marks the first time researchers have been…
