Uma equipe de cientistas identificou uma formação subterrânea há muito oculta sob os Estados Unidos, que remonta ao período Jurássico. A estrutura, descrita como um embasamento perdido, pode intensificar os efeitos de futuras tempestades solares na rede elétrica.
Pesquisadores identificaram a formação por meio de uma análise geológica recente. Ela se encontra em grande profundidade e é datada da era Jurássica, de acordo com as descobertas relatadas em 9 de maio de 2026.
Researchers from New York University Abu Dhabi have uncovered evidence that water flowed beneath Mars' surface billions of years ago, potentially sustaining habitable conditions longer than previously thought. Analysis of ancient sand dunes in Gale Crater, studied by NASA's Curiosity rover, shows minerals left by groundwater. These findings suggest subsurface environments could have protected microbial life after surface water vanished.

Scientists analyzing old radar data from NASA's Magellan spacecraft have identified evidence of a large underground lava tube beneath Venus's surface near Nyx Mons. The structure, potentially a kilometer wide and extending dozens of kilometers, highlights the planet's volcanic past. This discovery, led by researchers at the University of Trento, was published in Nature Communications.
Governor Gretchen Whitmer has directed state agencies to assess regulations for drilling geologic hydrogen, a potential clean fuel buried beneath Michigan. A recent U.S. Geological Survey study highlights the state as a promising location due to its geological features. Experts see it as a way to reduce emissions in hard-to-decarbonize sectors like shipping and trucking.

Researchers have created the first global map showing how Earth's deepest mantle is deformed, primarily in regions where ancient subducted tectonic slabs reside. Using over 16 million seismograms, the team confirmed patterns predicted by geodynamic models. The findings, published in The Seismic Record, offer new insights into mantle flow near the core-mantle boundary.
Environmental group Sélvame MX denounced on April 2 the resumption of works in a previously closed zone in Tulum, Quintana Roo, located over the Sac Actun underground river system. The organization warns of risks to the Gran Acuífero Maya and regional biodiversity. The works involve a roughly 20-kilometer road trace crossing cenotes and caverns.

German and Swiss foundations have awarded more than €1 million to study a major Roman sanctuary uncovered in Frankfurt. The site in ancient Nida, discovered during school construction, features unusual buildings and ritual deposits hinting at rare practices. Experts from multiple institutions will investigate over three years.
