Recent analysis of Iron Age artifacts from Poland has revealed the presence of meteoric iron in several ornaments, according to reports. The discovery was made at two archaeological sites, Częstochowa-Raków and Częstochowa-Mirów, both linked to the Lusatian Culture and dated between 750 and 600 BCE. A total of 26 iron artefacts, including bracelets, ankle rings, knives, spearheads, and necklaces, were examined, with four of them confirmed to contain meteoric iron.

Findings from the Study

According to the study published in the Journal of Archaeological Science: Reports, multiple analytical techniques were used to examine the artifacts, including portable X-ray fluorescence (p-XRF), Scanning Electron Microscopy (SEM) with Energy Dispersive Spectroscopy (EDS), and X-ray microtomography. These methods helped in determining the elemental composition and internal structure of the iron objects.

Dr. Albert Jambon, the lead researcher, told Phys.org that the aim of the study was to trace the origins of iron smelting. The presence of meteoric iron in the analyzed objects suggests that the material was sourced locally rather than imported from distant regions such as the Alps or the Balkans. The study further indicates that the artifacts were crafted from an ataxite meteorite, a rare iron meteorite with high nickel content.

Possible Meteorite Source and Cultural Context

Reports suggest that the meteoric iron used in these artifacts was likely obtained from a witnessed meteorite fall rather than an incidental discovery. Large iron meteorites are difficult to process without advanced tools, making smaller fragments more practical for use. Dr. Jambon explained to Phys.org that historical records from 19th-century France highlight similar challenges in working with large meteorite pieces.

Despite its extraterrestrial origin, meteoric iron does not appear to have been regarded as a prestigious material during the Iron Age. The artifacts were found in graves of men, women, and children, without any apparent social or economic distinction. None of the burial sites contained luxury items such as gold, silver, or imported goods, reinforcing the notion that iron was relatively common at the time.

Oldest Known Patterned Iron?

Further analysis revealed that the meteoric iron had been mixed with terrestrial slag iron, producing a distinctive banding pattern on the metal. Due to the high nickel content, meteoric iron would appear white when smelted, contrasting with the black hue of terrestrial iron. This suggests that the intentional mixing of different iron sources may have been an early attempt to create decorative or patterned metalwork. If confirmed, this would make the artifacts among the earliest known examples of patterned iron, predating the development of Damascus steel by centuries.

NASA’s SPHEREx Mission Sends First Space Images Before Full Sky Survey

NASA’s SPHEREx mission has sent back its first images from space. This marks an important step before it begins the full survey of the sky. The space telescope, which was launched on March 11, 2025, is designed to scan millions of galaxies and collect data in infrared light. On March 27, its detectors captured uncalibrated images that show thousands of light sources, including distant stars and galaxies. The images, processed with added colours for infrared wavelengths, confirm that SPHEREx is operating as expected. Once fully operational, the telescope will take 600 exposures daily and map the entire sky four times during its two-year mission.

Recorded Images Reveals Interesting Details

According to NASA’s SPHEREx mission, the observatory’s six detectors recorded images of the same area of the sky, providing a wide field of view. The top three images represent one portion of the sky, while the bottom three cover the same section. As per the report, the SPHEREx catpured each image with around 100,000 light sources. As per multiple reports, scientists can now learn more about what celestial objects and its distance from Earth with the help of infrared wavelengths. The data from SPHEREx will also help researchers to explore the origins of water in the Milky Way. Moreover, it might also help the scientists to find more clues about the universe’s earliest moments.

Olivier Doré, SPHEREx project scientist at NASA’s Jet Propulsion Laboratory (JPL) and Caltech, told NASA that the telescope is functioning as intended. The infrared light detected by SPHEREx is invisible to human eyes, but colour mapping enables researchers to visualise and analyse it. The observatory’s unique design includes 17 infrared wavelength bands for each detector, creating a total of 102 hues in every six-image capture.

How the Telescope Works

Unlike Hubble or the James Webb Space Telescope, which focuses on specific areas of space, SPHEREx is built for large-scale surveys. It uses spectroscopy to break down light and identify chemical compositions and distances of celestial bodies. Light entering the telescope is divided into two paths, each leading to three detectors. Specialised filters process the incoming wavelengths, allowing for detailed observations of millions of cosmic sources.

Beth Fabinsky, deputy project manager at JPL, said in NASA’s official statement that the successful image capture represents a major milestone. The telescope has also reached its target operating temperature of minus 350 degrees Fahrenheit, crucial for detecting faint infrared signals. Since focusing cannot be adjusted after launch, mission engineers verified the accuracy of the telescope’s optics before sending it into space.

Jamie Bock, principal investigator at JPL and Caltech, confirmed in NASA’s report that the telescope is performing as expected. Engineers will continue testing before the observatory begins routine operations in late April.

Iceland’s Grindavík town evacuated as volcanic fissure erupts with lava!

A volcanic fissure has emerged near Grindavík on Iceland’s Reykjanes Peninsula after a series of strong earthquakes. Lava has breached the town’s defence barriers. The Icelandic Meteorological Office (IMO) has warned that the fissure may continue to expand. The eruption began along the Sundhnúkur crater row early in the morning. By 9:45 a.m. local time, a fissure stretching nearly 1,200 metres had opened north of Grindavík. The crack is moving southward. Officials have raised the hazard level to the highest risk category.

Evacuations and Road Closures

According to the IMO, a second fissure has appeared inside Grindavík’s protective barriers. Authorities have evacuated the town along with the Blue Lagoon spa. Roads in and out of the area have been shut. Some residents have refused to leave. Local media outlet Visir has reported that emergency services remain on high alert.

Impact of Volcanic Gas

Weather forecasts indicate that volcanic gas will be carried northeastward towards Reykjavík. The capital is located about 40 kilometres away. The IMO has stated that by tomorrow morning, changing wind patterns may direct the gas southwest and eastward. Residents have been told to remain indoors as much as possible while closely monitoring air quality updates. Reykjanes Peninsula has experienced about 11 eruptions since 2021. Eight have occurred along the Sundhnúkur crater row since last year. Scientists continue to monitor the situation closely. Authorities have urged people to avoid the affected region.

JWST Captures Unseen Details of Exoplanets in HR 8799 and 51 Eridani Systems

Astronomers have released new images of planets within the HR 8799 and 51 Eridani star systems. The James Webb Space Telescope (JWST) was used in a way that was different from standard procedures to achieve these results. Capturing direct images of exoplanets is challenging due to the brightness of host stars, which often obscures planetary details. To allow more light through, researchers adjusted JWST’s coronagraphs. This helps in enhancing the visibility of these distant worlds. This adjustment provided clearer insights into planetary atmospheres and their compositions.

Unconventional Use of JWST’s Coronagraphs

According to a study published in The Astrophysical Journal Letters, lead author William Balmer, a Ph.D. candidate at Johns Hopkins University, explained to Space.com that a thinner part of the coronagraph mask was used. This allowed more starlight to diffract, reducing the risk of completely obscuring planets. Coronagraphs typically block starlight to reveal faint celestial bodies, but this modification provided a balance between removing excessive glare and preserving planetary details.

Key Discoveries and Observations

The JWST’s mid-infrared imaging captured HR 8799 at 4.6 microns. It is a wavelength that is mainly blocked by Earth’s atmosphere. Balmer stated that previous ground-based attempts had failed, demonstrating JWST’s stability in detecting exoplanets. Observations at 4.3 microns were also conducted. This revealed the presence of carbon dioxide. It is a very important step in determining the planetary formation processes. The detected carbon dioxide levels suggested that these planets likely formed through core accretion, gathering heavy elements over time.

Future Research and Expanding Studies

There are many research planned to study the four additional planetary systems. Balmer’s team has been allocated more JWST observation time to confirm whether similar gas giants formed through core accretion. This could offer more insights into the stability of planetary systems and potential habitability of smaller, unseen planets.
