Iran's Taftan Volcano Uplifts, Hinting at Wake-Up After 700,000 Years

Satellite data show the Taftan volcano in southeastern Iran rising about 9 cm (3.5 inches) over 10 months, signaling pressure building in a shallow hydrothermal system near the summit rather than a magma-driven eruption. Researchers say the uplift, detected by InSAR from Sentinel-1, warrants ongoing monitoring (gas emissions, seismometers, GPS) and hazard planning, since phreatic blasts could occur even without lava flows.

Biomass satellites frees its data stream to illuminate global forest carbon

ESA’s Biomass, a P-band radar satellite launched in 2025, has completed commissioning and now offers free, public access to its data to map forest structure and carbon storage. The mission begins with an 18-month global tomographic coverage, followed by multiple nine-month interferometric coverages to monitor forest change over time, with an airborne calibration campaign in Gabon aiding data validation and calibration. The effort aims to reduce uncertainties in global forest carbon stocks and support climate science and forest management.

T-Mobile Turns On Free Starlink Texting For Storm-Affected Areas

As Winter Storm Fern looms, T-Mobile activated free Starlink satellite text messaging for customers in potentially impacted areas with compatible phones, enabling basic texting and Wireless Emergency Alerts when cell towers fail; existing T-Satellite customers keep service, and the provider suggests the feature is text-only to avoid network strain.

Antarctica's Hidden Subglacial Landscape Unveiled from Space

A new ultra-high-resolution map of Antarctica’s bedrock beneath the ice combines satellite data and glacial-flow models to reveal a surprisingly varied subglacial landscape—from alpine valleys to eroded ice-stream troughs. Published in Science by Helen Ockenden and colleagues, the map refines projections of ice loss and sea-level rise beyond earlier radar surveys. The work highlights the importance of space-based data for understanding Antarctica, with a caveat that removing ice weight would cause the land to rebound."

NASA satellite captures detailed images of Pacific tsunami

NASA and French satellite SWOT captured high-resolution images of a Pacific tsunami caused by a 2025 earthquake, revealing complex wave patterns and challenging traditional models that treat large tsunamis as non-dispersive. The data suggest that dispersion plays a significant role in tsunami behavior, which could improve future forecasting and hazard assessment by integrating satellite, buoy, seismic, and geodetic data. This breakthrough highlights the need to update tsunami models to account for wave dispersion and internal structure.
