A groundbreaking discovery has been made in the Caucasus Mountains where an ancient Bronze Age settlement, Dmanisis Gora, has been mapped using drone technology. This site, believed to be over 3,000 years old, reveals new insights into the evolution of large-scale settlements during the Late Bronze Age and Early Iron Age. Spanning an area far larger than initially expected, the research offers a fresh perspective on ancient urbanism and interactions between sedentary and mobile communities.

Drone Mapping Reveals Extensive Settlement

As reported by Science Daily, the project led by Dr. Nathaniel Erb-Satullo, Senior Lecturer in Architectural Science at Cranfield Forensic Institute and Dimitri Jachvliani, co-director at the Georgian National Museum, employed drone technology to create high-resolution models of the site. The drone, equipped with advanced imaging tools, captured nearly 11,000 photographs, which were later used to generate detailed maps of the settlement. This method allowed the identification of fortification walls, graves and other structural remnants spread across a vast area.

The site, originally thought to be much smaller, was found to include a 1-kilometre-long defensive wall protecting an outer settlement. This finding significantly alters the understanding of the region’s settlement patterns, which were influenced by interactions with pastoral communities and seasonal population dynamics.

Integrating Modern and Historical Data

To further analyse the settlement, drone-generated images were compared with declassified satellite imagery from the Cold War era. This comparison highlighted changes in the landscape over decades, distinguishing ancient features from those impacted by modern agricultural activities. Geographic Information System (GIS) software was employed to integrate and analyse the diverse datasets, revealing patterns in the site’s expansion and usage over time.

Dr. Erb-Satullo noted to Science Daily, that these findings offer invaluable data on population density, agricultural practices and the broader socio-economic landscape of ancient societies. Continued excavations have uncovered artefacts such as pottery shards and animal remains, shedding more light on the lives of the people who inhabited Dmanisis Gora. This research underscores the potential of drone technology in unearthing and documenting historical sites on an unprecedented scale

The highly anticipated debut launch of Blue Origin’s New Glenn rocket has been scheduled for January 10, 2025. The heavy-lift rocket, designed for both commercial and government missions, will take off from Florida’s Cape Canaveral Space Force Station. A launch window of three hours, beginning at 1 a.m. EST, has been announced. The rocket’s inaugural flight marks a significant milestone for Blue Origin as the company aims to validate its capabilities and establish itself as a major player in the space industry.

New Glenn’s Mission and Capabilities

According to Blue Origin, as reported by space.com, the New Glenn rocket is a reusable, 320-foot-tall launch vehicle capable of carrying 50 tons (45 metric tons) to low Earth orbit (LEO). The NG-1 mission will test the company’s Blue Ring spacecraft platform, which is designed to support a variety of orbital payloads. This demonstration will include assessments of communication systems, in-space telemetry, and ground-based tracking capabilities. The payload will remain aboard the rocket’s second stage for a six-hour mission, as stated by Blue Origin.

Booster Recovery and Future Goals

The mission will also attempt a recovery of the rocket’s first stage booster, which will land on a ship stationed in the Atlantic Ocean, as per reports from space.com. The company’s senior vice president, Jarrett Jones, emphasised the importance of the flight, stating that rigorous preparations had been undertaken but that true insights could only be gained through actual launch experiences.

NG-1 is a critical step toward securing certification for U.S. national security missions. A successful outcome would bring Blue Origin closer to fulfilling these high-stakes contracts, further solidifying its position in the competitive aerospace sector.

This launch will serve as a proving ground for the New Glenn system, with valuable data expected to inform future missions and technology advancements.

Recent findings have challenged the traditional understanding of Jupiter‘s clouds, showing they are not primarily composed of ammonia ice. Instead, it has been discovered that the clouds are formed from ammonium hydrosulfide mixed with photochemical materials. This revelation, achieved through a collaboration of professional and amateur astronomers, sheds new light on the composition and dynamics of Jupiter’s atmosphere, offering simpler methods for mapping the planet’s cloud layers.

Ammonium Hydrosulfide Identified as Main Cloud Component

According to the study published in the Journal of Geophysical Research: Planets, the breakthrough came after amateur astronomer Dr. Steven Hill developed a method using commercial telescopes and specific filters to measure ammonia abundance and cloud-top pressures. His technique demonstrated that the clouds reside in warmer regions of Jupiter’s atmosphere, deeper than the expected ammonia cloud layer. This conclusion was confirmed when the method was applied to data from the Multi Unit Spectroscopic Explorer (MUSE) instrument on the Very Large Telescope in Chile.

Professor Patrick Irwin of the University of Oxford explained to phys.org that the simulations showed light interacting with gases at higher pressures and temperatures. This ruled out ammonia ice as the main component of the clouds and instead pointed to ammonium hydrosulfide mixed with smog-like materials. These substances are believed to contribute to the planet’s characteristic red and brown hues.

New Opportunities for Citizen Science

The study highlights how Dr. Hill’s method, which compares brightness levels in narrow color filters, matched the accuracy of complex computational techniques. According to a statement made to phys.org by John Rogers of the British Astronomical Association, this simpler method allows amateurs to frequently monitor variations in Jupiter’s atmospheric features, linking chemical changes to observable weather phenomena like storms and the Great Red Spot.

Photochemical reactions in Jupiter’s atmosphere are thought to prevent ammonia from condensing into clouds. Similar observations were made on Saturn, suggesting that photochemical processes play a significant role in shaping the atmospheres of gas giants.

A 2,300-year-old marble statuette discovered in Alexandria, Egypt, has offered new insights into how dwarves were perceived during the Ptolemaic period (332–150 B.C.). Depicting a muscular, nude dwarf in motion, the 4-inch sculpture reflects a combination of Egyptian and Greek artistic traditions. Despite missing its arms, legs, and part of the head, the craftsmanship of the piece indicates a highly skilled rendering of human anatomy. It is currently housed at the Metropolitan Museum of Art in New York City.

Depictions of Dwarves in Ptolemaic Art

According to information from the Metropolitan Museum of Art, as reported by Live Science, the statuette incorporates elements from Greek art, such as classical nudity and Hellenistic realism, blended with Egyptian cultural aesthetics. This synthesis points to the cultural exchange that characterised the Ptolemaic dynasty, a period when Egypt was ruled by Ptolemy I Soter, a general of Alexander the Great. The depiction of a dwarf engaged in dance suggests a significant societal role, unlike the exaggerated caricatures of dwarves often seen in Greek art.

Egyptian Perspectives on Dwarves

Historical records indicate that dwarves were highly regarded in ancient Egypt, often serving in the households of nobles and pharaohs. Their association with the god Bes, who was depicted as a short and muscular protector of families and women in childbirth, contributed to their societal acceptance. Bes, known as a dancer and tambourine player, symbolises strength and guardianship in Egyptian mythology. The statuette’s design, which likely depicted the dwarf with a percussion instrument, aligns with this cultural significance.

A Glimpse into Cultural Integration

The artifact demonstrates the integration of different human forms into Egyptian society during the Ptolemaic era. The Met has emphasised that such depictions reflect a broader tradition of valuing diverse body types, setting the Egyptian approach apart from other ancient civilisations. This statuette, though small in size, offers a profound understanding of cultural dynamics during a transformative period in history.
