The moons of Mars, Phobos and Deimos, could have formed from the remnants of an asteroid that was destroyed by the planet’s gravitational forces. Researchers from NASA and Durham University utilised advanced computer simulations to explore how such an event might have unfolded. These findings present a compelling new explanation for the origin of Mars’ two small moons, which have long puzzled scientists.

A New Model for Moon Formation

According to a study published in the Icarus Journal on November 20, a large asteroid, upon straying too close to Mars, crossed the planet’s Roche limit—a critical distance where tidal forces exceed an object’s structural integrity—leading to its disintegration. The resulting debris, according to simulations, would have gradually coalesced into Phobos and Deimos. Dr Jacob Kegerreis, a scientist at NASA’s Ames Research Center, stated in a statement that this new model offers an “exciting” alternative to previously considered theories about the moons’ formation.

Phobos and Deimos are unusual among the solar system’s moons. While their irregular shapes and small sizes resemble asteroids, their circular orbits, aligned with Mars’ equatorial plane, suggest they formed in orbit around the planet. Previous theories, such as their origin from impact ejecta or capture of asteroids, have struggled to fully explain their characteristics.

Simulations Provide Answers

Using Durham University’s supercomputers, researchers conducted hundreds of simulations, adjusting variables like the asteroid’s size, speed, and proximity to Mars. The results indicated that enough fragments could have survived to create a debris disk around the planet, eventually forming the two moons. Dr Jack Lissauer of NASA Ames explained in a press release that this model allows for efficient distribution of moon-building material, even from a relatively small parent asteroid.

Future Tests with MMX Mission

The Japanese Aerospace Exploration Agency’s (JAXA) Martian Moons eXploration (MMX) mission, launching in 2026, is expected to provide further insights. The mission will return samples from Phobos, which will be analysed for their composition. If similarities to Martian material are found, it may support the impact hypothesis, while asteroid-like material could validate this new model.

This research could also enhance understanding of planetary interactions with smaller celestial bodies across the solar system, opening doors to further exploration of moon and ring formation.

1,000-Year-Old Mummy Found by Gas Workers in Peru Linked to Chancay Culture

The gas workers in Peru discovered a mummy dated to a thousand years old during the time of pipe installation in Lima. The company named Calidda said this and confirmed this latest discovery of the prehistoric tomb in Peru. The workers found a trunk of the huarango tree, which is an inheritance of Peru’s coastal region. It served as a tomb marker in history and has a depth of 20 inches, as reported by the archaeologist Jesus Bahamonde to the gas company Calidda.

Archaeological Dig Found Mummy

Calidda also employed several archaeologists to get the excavation done at a deeper level in search of a heritage site in Lima. Archaeologist Jesus Bahamonde said that they found the mummy of a boy aged between 10 to 15, at a depth of 1.2 meters. The way of burial and the objects signaled its development between 1000 and 1200, he said. The mummy was found in a sitting position with the arms and legs bent, as per Bahamonde. They were shrouded and were found with the calabash gourds.

Mummy Belongs to the Pre-Inca Chancay Culture

Along with mummy, there were ceramic objects, such as plates, jugs, and bottles were found which were decorated with fishermen and geometric figures. This style of burial is similar to that of the Pre-Inca Chancay culture between the 11th and 15th centuries.

How they were found

The incident of digging took place when the gas workers were unearthing from an avenue in the district, Puente, located in northern Lima. In Peru, it is a must for the utility companies to hire archaeologists while drilling the Earth. This is because there is a possibility of getting any heritage sites.

Lima, A Place of Archaeological Sites

Till now, Calidda has made over 2,200 archaeological findings from the year 2004. Lima is home to over 500 archaeological sites, including 12 huacas, which are ancient cemeteries termed in the Indigenous Quechua language.

Radio Signal from Early Universe May Reveal the Masses of the First Stars

Radio Signal from Early Universe May Reveal the Masses of the First Stars

A faint radio signal beamed over the eons by hydrogen atoms in the early universe that contains important information about the mass and nature of the first stars. The finding is made by researchers, including those from the University of Cambridge, using a new model that for the first time investigates the effects of early starlight, which is produced by the first generation of stars, and the impact of the first supernovae on the 21-centimetre line from hydrogen. The finding gives us a new approach to learn about the Cosmic Dawn, a time when the cosmos changed from dark to light through the formation of stars and galaxies.

Early Universe’s Radio Signal Reveals Mass of First Stars, Say REACH and SKA Researchers

According to a report in Nature Astronomy, the team—including Professor Anastasia Fialkov from Cambridge’s Institute of Astronomy—demonstrated that the 21-cm signal, originating just 100 million years after the Big Bang, is sensitive to the masses of the first stars. These Population III stars are thought to be vastly different from stars today, and their influence on hydrogen gas could be tracked through radio observations. The work was conducted under the REACH project and contributes to the upcoming Square Kilometre Array (SKA).

Instead of visual observation like that performed by the James Webb Space Telescope, the REACH and SKA instruments collect statistical data about cosmic radio waves. In addition, they considered the impact of ultraviolet light and X-rays — produced by X-ray binary systems — on the 21-cm signal. They discovered that the impact of these factors on early cosmic rays had been underestimated in earlier studies, especially for what happens when collapsed stars interact with surviving stars in binary systems.

Though still in its calibration phase, REACH is already offering insights into the universe’s first billion years. Fialkov and her team think the technique might eventually determine not only when stars were forming but also how massive they were. “The outcomes of this project will define the future of radio astronomy, including site involvement from places such as the Karoo (South Africa),” explains Dr Eloy De Lera Acedo, REACH principal investigator.

These findings are a significant step toward understanding how the first objects in the universe developed from darkness to a galaxy.

Ancient Tel Dan Temple Reveals Centuries-Old Phoenician Ritual Bathing Traditions

A new archaeological find proves that ritual cleansing was a component of religious practice at an ancient sanctuary in northern Israel in the time of the kingdom of Israel. The sanctuary was equipped with a unique bathhouse, thought to have been used by the priests for ritual bathing. There, the diggers discovered two spaces — one room with yellow plaster, which had a dressing area, and another with walls of blue plaster and a basin — that offer a rare glimpse into how water was used in rituals of sacred purification. The discovery adds new depth to understanding Near Eastern religious practices linked to city-based deity worship.

Ancient Tel Dan Sanctuary Reveals Ritual Bathing Traditions Linked to Mysterious Deity Worship

According to a report published in Levant by Dr. Levana Tsfania-Zias, the sanctuary included a modest two-part bathing unit—featuring a yellow-plastered dressing room and a blue-plastered basin—suggesting ritual use by the priestly class. Unlike full-immersion baths, and because it is not heated, the basin’s size means worshippers might have washed themselves while standing, with cold spring water that flows into the Jordan from outlets nearby.

The first temple, constructed on a Middle Bronze Age rampart, had a tripartite plan of porch, cella, and adyton. A limestone fragment with inscriptions in both Greek and Aramaic, discovered in 1976, names an obscure deity and was almost certainly invoked in the central sanctuary of Dan. Scholars believe the deity’s identity remains uncertain due to the regional naming customs of ancient Near Eastern cities.

Following the destruction of the first temple by the Seleucids, a new temple was erected in its place, which preserved the bathing. After a 2-century gap, the site re-emerged in the Middle–Late Roman period for new purposes. Pilgrims were cleansed in a Fountain House, using primitive clay vessels that were likely smashed after use — a process mirrored in biblical texts describing ritual purity.

As so much of the sanctuary at Tel Dan remains in question, the scholars emphasised the significance of the site for the region. Dr. Tsfania-Zias believes the site would have been an attraction for both locals and visitors, something reinforced by imported ceramics and multilingual inscriptions that hint at a wider spiritual attraction. Deeper excavations could yet reveal what other deity or practices characterised this sacred spot in ancient times.
