Volcanic activities can generate economically valuable mineral deposits

"Super-wet" magmas play a critical role in forming large deposits of copper

Typically, most of the magmas hold 4-6% of water. Magmas containing 6-8% water are considered super-wet magmas, and the Department of Earth and Planetary Sciences, ETH Zürich suggests that such hydrous volcanoes can economically valuable mineral resources, especially Copper deposits. While the super-wet magmas are abundant at greater depths and not expected to persist at shallow depths, researchers think that are far more common than previously thought.

Mapping Our Cosmic Neighborhood: A 3D View of Near-Earth Objects

Watch all the known near-Earth asteroids and comets in real-time.

Astronomers discover many asteroids and comets each year, some of which are near-Earth objects (NEOs) that move through the inner solar system. NASA-funded researchers track these objects to identify potential threats to Earth. To help visualize them, NASA launched Eyes on Asteroids, a 3D real-time tool that shows NEOs moving through Earth’s orbital neighborhood.

Birds, badgers, and bees: Investigating africa’s honey thieves

A comparable cooperative relationship between honeyguides and honey badgers.

Researchers from nine African countries investigated whether honeyguide birds and honey badgers work together to find honey. After interviewing over 400 honey hunters, they found that while honeyguide birds often lead people to beehives, no one has ever seen them cooperating with honey badgers. Most of the 11 villages surveyed (80%) have been hunting for wild honey for centuries, often with help from honeyguide birds.

First-ever images reveal the cosmic web’s hidden structure

These findings are fundamental.

Astronomers used the MUSE1 instrument on ESO’s Very Large Telescope in Chile to capture the first-ever images of the cosmic web in the early universe. The project took eight months of observations, followed by a year of data processing. Their analysis revealed glowing hydrogen filaments, showing structures as they appeared one to two billion years after the Big Bang.

Axial Seamount: Underwater Volcano Poised to Erupt

A rare glimpse into Earth’s hidden forces—scientists brace for a deep-sea eruption off Oregon’s coast.

Axial Seamount, an underwater volcano 300 miles off Oregon’s coast, is showing strong signs of an impending eruption—the first since 2015. Though invisible from land, its activity is closely monitored by the Regional Cabled Array, providing real-time data on earthquakes, lava flows, and deep-sea ecosystems. Scientists are eager to study this eruption to better understand Earth's geological processes and improve eruption predictions. While harmless to people, Axial’s eruptions reshape the seafloor, impact hydrothermal vents, and reveal how life thrives in extreme environments—offering a rare window into the power beneath our oceans.
