A 15-kilometre-long mass of lava has formed underneath the Reykjanes peninsula in Iceland and could erupt at any time

Once seen as miraculous, these days ice is no longer extraordinary. But in a winter season when Antarctic sea ice hit a historic low, it is clear we should cherish it more, says Max Leonard

Iceland is bracing for a volcanic eruption, as thousands of small earthquakes have shaken the southern part of the Reykjanes peninsula since October

When most people are asked to name a river, they often reach for the Amazon or Nile, but these aren’t the only remarkable rivers out there. Here are 10 more from around the world – and solar system

Few volcanos come with more risk than Mexico's Popocatépetl, situated near Mexico City.  To mitigate danger, volcanologist Chiara Maria Petrone is trying to predict its next eruption

Some 550 years ago, a Venetian monk named Fra Mauro set out to create a world map. Rather than myth and religion, it was based on solid evidence for the first time

Iceland’s Fagradalsfjall volcano, located on the country’s south-west Reykjanes peninsula, has erupted after weeks of earthquake activity

The stratosphere seems to be full of aluminium particles and other metals that come from spacecraft burning up in the atmosphere, and those particles could mess up polar clouds

A drilling project in the Taklamakan desert is aiming to reach more than 11,000 metres below Earth’s surface as China explores the deep earth for resources

This spectacular selection of images is taken from the winners of the Northern Lights Photographer of the Year competition, run by Capture the Atlas

An area of the seabed north of Australia has been mapped in detail for the first time, revealing that large numbers of people could have lived there until it was inundated by rising seas

In Iceland, scientists are planning to drill two boreholes to a reservoir of liquid rock. One will give us our first direct measurements of magma – the other could supercharge geothermal power

Several enormous craters left by explosions have been spotted in Siberia over the past 15 years, and a new explanation links them to hot gas – and climate change

Photographer Matjaz Krivic has been charting the effects of lithium mining on locals in the world's largest salt flat in Bolivia since 2016

Lightning strikes during volcanic eruptions could have provided nitrogen in a form that was needed by early life forms

An analysis of satellite observations has identified some extreme thunderstorms over the Indian Ocean and Gulf of Mexico with lightning flashes so frequent that the sky would appear continuously lit

An ocean research vessel has just discovered four underwater mountains, the tallest almost 3 kilometres high, that might be hotspots of deep-sea life

Companies are searching all over the world for deposits of geologic hydrogen that could be used as clean fuel, and a mine in Albania could give them clues about where to look

As a 15-kilometre crack formed ahead of the recent eruptions, magma flowed into it at the highest rate observed anywhere in the world

Microbes that rapidly convert CO2 to rock could lock away the greenhouse gas in deep underground storage sites, such as depleted oil and gas reservoirs

The Kikai-Akahoya eruption of an underwater volcano off the coast of Japan ejected enough material to fill Lake Tahoe twice, three times as much as the eruption of Mount Tambora in 1815

Global warming means many of the world’s ancient rivers of ice will be gone within decades, threatening ecosystems that rely on their meltwater, a looming crisis that photographer Edward Burtynsky highlights in his work

Mysterious green sunsets were reported after the massive eruption of Krakatoa in 1883 – now simulations show how they were created and just how rare they are

A proposal to define the Anthropocene, a geologic epoch defined by human activity, has been rejected – surprising even scientists who consulted the voting group

Humans are drastically changing the planet and the Anthropocene is a useful tool to help us deal with that – so let's stop quibbling over definitions

A huge plume of sulphur dioxide from the latest eruption in Iceland is drifting across Europe, but it isn't expected to cause any significant harm

Strange volcanoes called kimberlites bring diamonds up from Earth's depths. Scientists have always struggled to understand why they switched off millions of years ago – but perhaps they didn't
