New Scientist embarks on a quest to make record-breaking snowflakes. This is our journey into the complex world of snow physics
Geologists surprisingly declined to formally declare a new epoch, but proponents of the Anthropocene will continue to highlight humanity’s impact on the planet
How chlorophyll data from satellites is helping scientists understand and mitigate changes in warming oceans
A high-resolution view of hailstones the size of tennis balls can reveal how they form – and help researchers better forecast which storms will generate these destructive pieces of ice
Wildfires are already changing as a result of climate change but we don’t know what will happen as our planet gets even warmer. The answer could be hidden underground
Rising carbon dioxide levels are driving an increase in the ocean’s acidity – and this change is sinking deeper as emissions increase, putting even more marine organisms at risk
A new volcanic eruption has occurred on Iceland’s Reykjanes peninsula, the seventh this year
A supercomputer simulation of iron and carbon atoms in Earth’s inner core may explain how a molten ball at the centre of our planet froze solid
An analysis of crystals in lava from the 2022 eruption of Mauna Loa has revealed an unknown magma reservoir within the volcano, which could extend forecasts of eruptions from minutes to months
Forget Armageddon-sized rocks, just one of 25,000 smaller asteroids could destroy a city on Earth. How to Kill an Asteroid by Robin George Andrew shows how science plans to save the planet
Endurance sank beneath the ice during Ernest Shackleton’s legendary Antarctic expedition. More than a hundred years later, researchers document their own saga of how they found the vessel
In the western US, the average maximum growth rate of fires has more than doubled over the past two decades
A story passed down in folklore led scientists to evidence of an 8-metre tsunami that hit an island in Hawaii hundreds of years ago
El Niño and La Niña cycles driven by ocean temperatures in the Pacific can influence weather in the North Atlantic 12 months later – a finding that could improve long-range forecasts
Rapid erosion caused by a geological act of “piracy” tens of thousands of years ago may have raised Earth’s crust and elevated Mount Everest by as much as 50 metres
A sprawling research program aims to improve hurricane forecasts by collecting data at the chaotic interface of ocean and atmosphere
Geographer Alastair Bonnett on his pick of the most diverse maps, from a collection of 100,000 galaxies to a 12th-century Chinese depiction of rivers on a grid
A ring of asteroid debris could have orbited Earth for tens of millions of years, and perhaps even have altered the planet's climate
Seismologists were mystified by a strange signal that persisted for nine days in 2023 – now its source has been identified as a standing wave caused by a landslide in Greenland
This claustrophobia-inducing image is taken from photographer Martin Broen's new book Light in the Underworld, a collection of shots from the Yucatán’s cenotes, or sinkholes
