A transition may be coming for a massive Italian volcano - Live Science

Orbital observations suggest that a deeply eroded region near Mars’ equator contains the remains of a giant volcanic complex. Landforms and sulfate deposits point to past interactions between volcanic material and ice, but surviving buried glacier ice remains unconfirmed. Follow-up research and a proposed helicopter mission highlight the region’s scientific appeal without establishing present volcanic activity or a usable water reserve. A maze of fractured plateaus and canyons near Mars’ equator may preserve the remains of an enormous volcano. Within that landscape, scientists have also identified clues that glacier ice could survive beneath volcanic debris. Together, the observations make eastern Noctis Labyrinthus a compelling target for investigating the planet’s changing environment. The proposal concerns terrain already photographed by generations of spacecraft. Its significance lies in recognizing a possible geological structure within that familiar landscape, rather than discovering an unseen mountain. The volcano’s history and the present condition of any buried ice remain open questions.

An AI-generated image illustrating the concept of a geothermal plant drilling into a volcano’s magma chamber. An initiative that sounds a lot like Jules Verne‘s Journey to the Center of the Earth could open a new frontier in geothermal energy by deliberately drilling into magma, the molten rock beneath Earth’s surface.

Given how many people are on and around this well-and-truly active volcano, scientists are keeping a very close eye on what it's up to. Now, it appears two reservoirs of magma lurking within the volcano are active at the same time. Those are the findings presented in Geophysical Research Letters by a team from Pennsylvania State University, based on Sentinel-1 satellite radar images taken roughly every 12 days for six years. The volcano's famous lava lake is just a small surface feature of the much larger volcano complex, which researchers are still trying to understand, so they can better understand what risks face nearby residents and the droves of tourists that come through daily. Around 2 million people live in close proximity to the volcano. Managua, the capital city of Nicaragua, is about 20 kilometers (12 miles) away.

To test the approach, they compared more than 1,500 one-dimensional Spheral simulations with asteroid deflection results. (Representational image)MARK GARLICK/SCIENCE PHOTO LIBRARYResearchers in the United States are developing three-dimensional simulations to examine how a nuclear device could be used to deflect or potentially disrupt an asteroid threatening Earth. The team from Lawrence Livermore National Laboratory (LLNL) uses Spheral simulation code to more accurately model how an asteroid might respond when X-rays from a nuclear device detonated near its surface rapidly heat and vaporize material. After validating the approach against established asteroid-deflection models, researchers used Spheral to study three complex disruption scenarios. Hazardous asteroid impact could potentially be prevented
