Une équipe de scientifiques a identifié une formation souterraine longtemps restée cachée sous les États-Unis, datant de la période jurassique. La structure, décrite comme un socle oublié, pourrait amplifier les effets des futures tempêtes solaires sur le réseau électrique.
Les chercheurs ont identifié cette formation grâce à une analyse géologique récente. Elle se trouve profondément enfouie sous terre et remonte à l'ère jurassique, selon les résultats rapportés le 9 mai 2026.
The Chicxulub asteroid impact that ended the dinosaur era left the site in what is now Mexico hot enough to sustain underground microbial life for at least 8 million years. New analysis of rock cores shows the hydrothermal system lasted far longer than earlier estimates suggested.

Researchers have mapped a massive fan-shaped network of basins beneath the East Antarctic Ice Sheet, linking several previously studied features into one large geological structure. The discovery, published in a 2026 study, offers new insights into the continent's tectonic past and its influence on current ice movement.
Researchers have traced the origins of diverse early space rocks to a dust trap just outside Jupiter's orbit. The findings come from computer simulations matching meteorite compositions found on Earth. They suggest this region produced multiple generations of planetesimals over millions of years.

A massive body of magma surged upward beneath São Jorge Island in Portugal's Azores archipelago in March 2022, triggering thousands of earthquakes before stalling underground. The event, detailed in a new study, represented a failed eruption that raised but ultimately eased fears of volcanic activity.
Scientists have determined that structures once seen as traces of tiny animals in 540-million-year-old Brazilian rocks are actually fossilized communities of bacteria and algae. The reexamination uses advanced imaging to reveal preserved cells and organic material.
