On Oct. 25, 2025, Europe's Sentinel‑2 satellite mission captured a striking image of the Planchón-Peteroa volcanic complex, located on the border between Chile and Argentina, emitting a plume of ash and volcanic gas rising roughly 1,970 feet (600 meters) above the crater. The ash plume drifted north‐northwest initially and then, under changing wind conditions, veered eastward across the Argentine side. The Sentinel-2 satellites, developed and operated by the European Space Agency, use high-resolution optical imaging to monitor land surfaces, coastal zones and inland waters. There are currently three Sentinel-2 satellites in orbit — Sentinel-2A, Sentinel-2B and Sentinel-2C, which launched in 2015, 2017 and 2024, respectively. They're part of the European Union's Copernicus Earth-observation program, whose first satellite (Sentinel-1A) launched in 2014. The Planchón-Peteroa complex sits in the Andes mountain range, at a high altitude in a region dominated by snow‐covered peaks and volcanic terrain. Because the Planchón-Peteroa volcanic complex is remote, rugged and spans two countries, satellite imagery plays a vital role in monitoring volcanic activity, ash dispersal and potential impacts on air pollution, local communities and the environment. The snow-covered ground enhances the visibility of the ash plume as it drifts across the landscape, allowing for better tracking by the ESA satellite. With the ash crossing from Chile into Argentina, the image shows how volcanic events do not respect national boundaries — and international monitoring systems like Copernicus are key.

BEIJING, Nov. 7 (Xinhua) -- China's foreign exchange reserves totaled 3.3433 trillion U.S. dollars at the end of October, an increase of 4.7 billion U.S. dollars, or 0.14 percent, from the end of September, official data showed on Friday. The State Administration of Foreign Exchange stated in a statement that the U.S. dollar index rose and global financial asset prices generally increased last month, influenced by factors such as macroeconomic data, monetary policies and economic outlooks in major economies. Driven by exchange rate conversions and changes in asset prices, China's foreign exchange reserves increased during the month, the administration said.
Somon Air announced (06-Nov-2025) plans to order up to four Boeing 787-9s and up to 10 737 MAX 8s. Somon Air CEO Abdulkosim Valiev stated: "This significant investment not only marks our first widebody order but also reinforces our dedication to providing exceptional service and comfort to our passengers". The airline plans to utilise the 787-9s to operate long haul services and the 737 MAX 8s for short and medium haul services. [more - original PR]
