The maximum number of sunspots in solar cycle 25 was reached in late November and early December 2024, and it remains more active than expected. What awaits us in 2025? Experts tell us about it and its impacts.
A new model suggests how gold from deep underground can emerge in layers close to the Earth's surface and thus be extracted.
Astronomers are studying a galaxy that appears to be staring at us from afar using data and images from the Hubble Space Telescope.
A new NASA-led study has found that how rain falls in a given year is almost as important to the world's vegetation as how much.
Scientists say that over the past four years, the annual ozone hole over Antarctica has remained open for longer than usual and closed in the second half of December 2024, according to Copernicus data.
The Arctic is characterised by its cold, harsh climate and limited daylight hours during the winter. But this typically frigid region is warming about four times faster than the rest of the planet, which has facilitated increased transport and development.
Where does water in Earth's oceans come from? It is an open question that has scientists constantly researching, and comets may have part of the answer.
According to an analysis of 35 years of Landsat satellite observations, the amount of vegetated land on the Antarctic Peninsula has increased more than tenfold since 1986.
Scientists have discovered that a sample brought into space from the asteroid Ryugu was rapidly colonised by terrestrial microorganisms when placed in a hermetically sealed chamber to prevent contamination.
A scientist was examining satellite images of Australia's Nullarbor Plain when he came across something unexpected: a huge, mysterious mark etched into the arid landscape.
What kind of astronomical object is this? It doesn't look much like the kinds of galaxies, nebulas, star clusters or galaxy clusters that Hubble normally images.
A group of researchers show that the North Pacific Garbage Island is constantly increasing and that it is made with plastics from around the world.
A powerful storm in explosive cyclogenesis could be associated with a category 4-5 atmospheric river loaded with extreme humidity that could leave abundant rains and generate floods in areas of the western continental United States.
NASA satellites have detected a worrying drop in freshwater levels in recent years and scientists are trying to analyse the reasons and impacts of this significant decrease.
An astronaut aboard the International Space Station, ISS, took this photograph while orbiting over North Africa and observed some rare structures known in Morocco.
The forever chemicals, or PFAS, are present in rainwater, a scientific study in Miami shows. These compounds influence people's health and impact marine and terrestrial ecosystems.
By analysing tree rings, scientists have found that a past Chinese dynasty collapsed due to a prolonged megadrought and not something else as previously believed.
As the climate warms, vegetation in far northern forests is changing as more trees and shrubs appear, according to new NASA research.
The Sahara Desert can be thought of as a vast expanse of barren sand, an extreme environment for plants and animals to thrive. But in fact, vegetation growth in the desert has waxed and waned over millennia, with periods of increased growth referred to as “green-up.”
