A significant discovery has been made near the Dutch village of Hezingen, where a 1,300-year-old hoard of gold and silver has been unearthed. The site, located approximately 130 kilometers east of Amsterdam, is believed to have been used for pagan rituals. The artifacts include more than 100 gold and silver coins, jewelry and other valuables, indicating the presence of a religious offering site. The term “devil’s money” was used by Christian missionaries at the time to condemn such practices, as per reports. Researchers believe the site may have been a place of worship in response to the growing influence of Christianity in the region.

Findings Indicate Pagan Ritual Practices

According to the study published in Medieval Archaeology, the discovery comprises multiple deposits of gold and silver, suggesting repeated offerings over time. The coins originate from various Frankish mints, dating back to the first half of the seventh century. Some jewelry pieces exhibit Germanic animal-style motifs, while others reflect Roman influences. The presence of large silver and gold fragments, possibly used as currency by weight, further indicates the site’s significance. Geochemical analysis has also revealed traces of decayed bones, suggesting that animal sacrifices may have taken place alongside these offerings.

Historical Context and Archaeological Evidence

Jan-Willem de Kort, archaeologist at the Cultural Heritage Agency of the Netherlands and lead author of the study, stated to Live Science that the site was within an area traditionally linked to Saxon communities, although the term “Saxons” may have been a broad classification used by outsiders. The region was once near the Lower German Limes, a former boundary of the Roman Empire before its decline in the fifth century. Some local inhabitants may have served in the Roman auxiliary forces, but by the sixth and seventh centuries, the site appears to have been dedicated to pagan rituals.

Architectural Features and Ritual Significance

During excavations, a line of 14 postholes aligned with the east-west axis was identified. Some of the metal artifacts were found in these postholes, suggesting that they may have once held wooden posts used in rituals. De Kort suggested that the central posts could have supported a “holy pillar,” a feature referenced in early Christian texts as an element of pagan worship. The alignment of these structures with the equinoxes indicates a possible connection to agricultural cycles, where offerings might have been made to ensure fertility and a successful harvest.

Christian Influence and Suppression of Pagan Practices

Historical records indicate that early Christian missionaries opposed these rituals. A ninth-century Saxon baptismal promise explicitly required converts to renounce “diobolgeldæ,” or “devil’s gold.” This aligns with efforts by Christian rulers, such as Charlemagne, to eradicate pagan customs in the region. The persistence of such offerings despite these efforts suggests that some communities continued their traditional practices in defiance of Christian influence.

Cultural Significance of the Discovery

The artifacts provide valuable insights into the religious landscape of early medieval Europe. The hoard not only reflects the material wealth of the time but also highlights the resistance of local communities to the Christianisation process. The site near Hezingen represents one of the most well-preserved examples of pagan ritual practices from this period, offering a glimpse into the region’s complex cultural and religious history. Further analysis of the artifacts and site may provide deeper understanding of the transition from pagan traditions to Christian dominance in medieval Europe.

NASA Satellite Detects Tree Leaf Changes as Early Volcano Eruption Warning Signal

NASA Satellite Detects Tree Leaf Changes as Early Volcano Eruption Warning Signal

NASA scientists might soon be able to forecast volcanic eruptions by monitoring how trees respond from space. Now, in a new collaboration with the Smithsonian Institution, they have discovered that tree leaves grow lusher and greener when previously dormant volcanic carbon dioxide seeps up from the ground — an early warning that a cone of magma is pushing upwards. Now, using satellites such as Landsat 8 and data from the recent AVUELO mission, scientists think this biological response could be visible remotely, serving as an added layer of early warning for eruptions in high-risk areas that currently menace millions worldwide.

NASA Uses Tree Greening as Satellite Clue for Early Volcano Eruption Warnings in Remote Regions

As per the research by NASA’s Earth Science Division at Ames Research Centre, greening occurs when trees absorb volcanic carbon dioxide released as magma rises. These emissions precede sulfur dioxide and are harder to detect directly from orbit.

While carbon dioxide does not always appear obvious in satellite images, its downstream effects — enhanced vegetation, for example — can help reinforce existing volcanic early warning systems, notes volcanologist Florian Schwandner. It could be important because, as the U.S. Geological Survey says, the country is still one of the most volcanically active.

Globally, about 1,350 potentially active volcanoes exist, many in remote or hazardous locations. On-site gas measurement is costly and dangerous, prompting volcanologists like Robert Bogue and Nicole Guinn to explore tree-based proxies.

Guinn’s study of tree leaves around Sicily’s Mount Etna found a strong correlation between leaf colour and underground volcanic activity. Satellites such as Sentinel-2 and Terra have proven capable of capturing these subtle vegetative changes, particularly in forested volcanic areas.

To confirm this method, climate scientist Josh Fisher led NASA-Smithsonian teams in March 2025 to Panama and Costa Rica, collecting tree samples and measuring gas levels near active volcanoes. Fisher sees this interdisciplinary research as key to both volcano forecasting and understanding long-term tree response to atmospheric carbon dioxide, which will reveal future climate conditions.

The benefits of early carbon dioxide detection have been demonstrated in the 2017 eruption of Mayon volcano in the Philippines, where it allowed mass evacuations and saved more than 56,000 lives. It has its limitations, like bad terrain or too much environmental noise, but it could be a game-changer.

Russian Researchers Discover 11 New AGNs in All-Sky X-ray Survey

11 new active galactic nuclei were detected in an all-sky X-ray source survey conducted by researchers from the Russian Academy of Sciences. A team led by Grigory Uskov has been on an inspection of the X-ray sources found in the ART-XC telescope of the Spektr-RG (SRG) space observatory. So far, their studies have resulted in the identification of more than 50 AGNs and several cataclysmic variables. A deeper dive into the physical properties and radiation nature of those galaxies will be crucial for a wide range of studies such as statistical insights, refining and testing cosmological models, classification studies etc.

Classification of newly found AGN

According to the recent study published in Astronomy letters, the newly discovered active galactic nuclei from the ARTSS1-5 catalog are categorised as the Seyfert galaxies, seven type 1 (Sy 1), three type 1.9 (Sy 1.9) and one type 2 (Sy 2).

AGN or active galactic nuclei are considered as the most luminous persistent sources of electromagnetic radiation in the universe. These compact regions at the centre of a galaxy are extremely energetic due to accretion onto a supermassive black hole or star formation activity at the galaxy’s center.

Based on their luminosity, AGNs are categorised as Seyfert Galaxies and Quasars. Seyfert galaxies are lower-luminosity AGNs where the host galaxy is clearly visible and emit a lot of infrared radiation, and have broad optical emission lines.

Research findings

The published paper states the 11 newly found galaxies are located relatively nearby, at redshifts of 0.028-0.258. The X-ray luminosities of these sources are within the range of 2 to 300 tredecillion erg/s, therefore typical for AGNs at the present epoch.

The spectrum of one of the new AGNs, designated SRGA J000132.9+240237, is described by a power law with a slope smaller than 0.5, which suggests a strong absorption and a significant contribution of the radiation reflected from the galaxy’s dusty torus. The authors of the paper noted that longer X-ray observations are required to determine the physical properties of this AGN.

New Study Reveals Recent Ice Gains in Antarctica, But Long-Term Melting Continues

Global warming and climate change have been subjects of major concern for a long time. One of the key indicators of this phenomenon is the melting of ice in the polar regions. Researchers from Tongji University in Shanghai have been using NASA satellite data to track changes in Antarctica’s ice sheet over more than two decades. Their newest study states that despite the increase in global temperature, Antarctica has gained ice in recent years. However, it cannot be considered as a miraculous reversal in global warming because over these two decades, the overall trend is substantial ice loss. Most of the gains have been caused by unusual increased precipitation over Antarctica.

About the New study

According to the new study , NASA’s Gravity Recovery And Climate Experiment (GRACE) and GRACE Follow-On satellites have been monitoring this ice sheet since 2002. The ice sheet covering Antarctica is the largest mass of ice on Earth

The satellite data revealed that the sheet experienced a sustained period of ice loss between 2002 and 2020. The ice loss accelerated in the latter half of that period, increasing from an average loss of about 81 billion tons (74 billion metric tons) per year between 2002 and 2010, to a loss of about 157 billion tons (142 billion metric tons) between 2011 and 2020, according to the study. However, the trend then shifted.

The ice sheet gained mass from 2021 to 2023 at an average rate of about 119 billion tons (108 metric tons) per year. Four glaciers in eastern Antarctica also flipped from accelerated ice loss to significant mass gain.

General Trend in global warming

Climate change doesn’t mean that everywhere on Earth will get hotter at the same rate, so a single region will never tell the whole story of our warming world.

Historically, temperatures over much of Antarctica have remained relatively stable, particularly compared to the Arctic. Antarctica’s sea ice has also been much more stable relative to the Arctic, but that’s been changing in recent years.
