Ice production on the hottest planet in our solar system
Water is crucial to life on Earth. It is also present on other planets and solar system bodies. Indeed, ground-based radar observations and space probe data indicated the presence of frozen water ice even on Mercury, the hottest planet in our solar system! Water, in... click to read more
How rain sculpts mountains
The shape of Earth's surface can tell us a lot about what kinds of natural events have happened in a region and when. Heavy rainfall, for instance, causes rivers to swell, which can force a river to erode faster into its bed. This connection between... click to read more
Using satellites to look for floating plastics in the ocean
Plastics in the marine environment pose a significant threat to marine life. Macroplastics entering ocean waters have two fates - floating on the surface, or sinking. If not removed by clean-up operations, they may harm or even kill marine life through entanglement or ingestion, and/or... click to read more
What the Earth’s ‘voice’ tells us about its underground architecture
What's under our feet? Our planet has layered internal structures – the central inner and outer cores covered by mantle, crust, and the ground on which you are standing. While these layers are mostly solid, the outer core is liquid since it's extremely hot (around 3000°C)... click to read more
Bringing 100 million-year-old marine microbes back to life
The Earth's entire surface is inhabited by life, but what about what lies beneath, in the subsurface? In the past, we thought of the deep subseafloor as a lifeless zone. We now know it is the "subseafloor biosphere" inhabited by a substantial percentage of Earth's... click to read more
