Explanation: Are meteors streaming out from a point in the sky? Yes, in a way. When the Earth crosses a stream of Sun-orbiting meteors, these meteors appear to come from the direction of the stream – with the directional point called the radiant.  An example occurs every mid-December for the Geminids meteor shower, as apparent in the featured image.  Recorded near the shower’s peak in 2013, the featured skyscape captures Gemini’s shooting stars in a four-hour composite from the dark skies of the Las Campanas Observatory in Chile. In the foreground the 2.5-meter du Pont Telescope is visible as well as the 1-meter SWOPE telescope. The skies beyond the meteors are highlighted by Jupiter, seen as the bright spot near the image center, the central band of our Milky Way Galaxy, seen vertically on the image left, and the pinkish Orion Nebula on the far left. Dust swept up from the orbit of active asteroid 3200 Phaethon, Gemini’s meteors enter the atmosphere traveling at about 22 kilometers per second. The 2019 Geminid meteor shower peaks again this coming weekend.

Jewellery made from 'human teeth' found in Catalhoyuk

Archaeologists in the Neolithic proto-city of Catalhoyuk site in modern-day Turkey have discovered a set of human-teeth pendants that are believed to date back to 6500 BC. It is now being said that since human-teeth jewellery is rare in the Near East, the discovery could shed important light into the funerary rituals and customs of the region.

Speaking about the discovery, researcher Scott Haddow of the University of Copenhagen who led the Catalhoyuk excavation along with an international team of archaeologists said that the teeth seem to have belonged to middle-aged adults. He further added that it is highly possible that at least two of them were possibly extracted postmortem.

Additionally, it was also found that out of all the teeth, two or three of them were in perfect condition with no signs of tooth damage, pointing to the fact that they were still perfectly healthy. Considering the condition of the teeth, researchers are now trying to determine if the teeth bearers were alive or dead at the time of their extraction.

The teeth, when discovered, were chiselled into a conical shape using a microdrill. It was also observed that the same instrument could also have been used to drill the neat holes at the conical tip of the teeth so that they could carry the teeth as pendants. According to Forbes, researchers also felt that the drill-work was probably done by trained professionals who understood the work.

Catalhoyuk, where the discovery was made, was occupied between 7100 and 5500 BC. It is also a UNESCO World Heritage site. Research documents suggest that excavation work first began on the site in the 1960s. The site has, over time, become an important one to study Neolithic cultures and ways of life. Several domestic buildings have been found on the site along with ornamental objects depicting or derived from animals teeth or bones, suggesting that the place was once inhabited and fully functional. The site is also believed to have been witness to an evolved, egalitarian society.

The findings are published in the Journal of Archaeological Science: Reports.

Life of a foam

Dec. 6, 2019

Foam bubbles

A fine coffee froth does not last forever. The bubbles that make the milk light and creamy are eventually torn apart by the pull of gravity. But there is a place where foams have a more stable life – in the weightless environment of the International Space Station, bubbles don’t burst so quickly and foams remain wet for longer.

Beyond the pleasures of sipping a cappuccino with its signature froth, the presence of foams in our daily lives extends to food, detergents, cosmetics and medicines. However, creating the perfect bubble for the right foam is tricky.

Three experiments will investigate properties of foam

On Earth, the mixture of gas and liquid that makes up a foam quickly starts to change. Gravity pulls the liquid between the bubbles downwards, and the small bubbles shrink while the larger ones tend to grow at the expense of others. Due to the drainage, coarsening and rupture of the bubbles, foam starts to collapse back to a liquid state.

A foam’s existence in space is marked by more equilibrium because drainage is suppressed. Bubble sizes are evenly spread and that makes it easier for scientists to study it in more detail.

Lessons on foams in space

In 2009, ESA astronaut Frank De Winne ran the Foam Stability experiment on the International Space Station. Frank shook several liquid solutions contained in 60 closed cells and recorded what happened next. The samples ranged from pure water to protein-based fluids, like the ones used for chocolate foams, and antifoaming agents.

After just ten seconds, fluids stabilised more quickly and produced more foam than on Earth. Scientists discovered that it was possible to create super stable foams in zero gravity.

Intact deposit of prehistoric funerary vessels found in Minorca

An intact deposit comprising a collection of some 50 well preserved prehistoric vases, accompanied by the remains of bones of animals, mainly goats, sheep and pigs, has been documented by a group of archaeologists from the Museum of Minorca in what is considered "an exceptional find".

The discovery is still in the process of being studied but specialists interpret that this deposit of vases would have formed part of the funerary rituals of commensality linked to burials in lime arranged within the hypogeum, an event never before documented in Minorca.

On the occasion of the forthcoming exhibition dedicated to the archaeologist Joan Flaquer Fabregues (1887-1963), promoted by the Museum of Minorca, several studies have been carried out dedicated to his figure as well as his private collection, which has been deposited in the Museum since 2017.

The Museum explains that "from these investigations it has been known that a significant number of the prehistoric vases in this private collection, totalling almost 300, come from a hypogeum located in La Mola (Alaior). Most of these vases, which come from the final Talayotic (dated between the third and second centuries BC), are of a type unique and exclusive to the island of Minorca: the high-bottomed vase that has always been related to ritual and symbolic purposes. This discovery was exceptional, although Joan Flaquer never published the results of this excavation".

In order to reopen the scientific study that Joan Flaquer began with the discovery of the La Mola deposit at the beginning of the 20th century, a team of archaeologists from the Museum of Minorca has launched new archaeological research at the site.

"The intervention was based on the scant and vague information found in Joan Flaquer's personal notes, and also from the publications of other archaeologists and friends such as Julio Martinez Santa-Olalla. We also know that his mentor Antoni Vives Escudero collaborated with Flaquer in the excavation of Sa Mola between 1915 and 1920. In addition, a 1917 letter from Flaquer to Vives Escudero has survived, in which a sketch of the place where the vases were deposited, outside the hypogeum, appeared. The vast majority of authors suggest that the site was a sanctuary dedicated to some deity, perhaps the Punic goddess Tanit", the Museum points out.

The team of archaeologists, comprising Montserrat Anglada, Octavio Pons and Bruno Pares, and coordinated by the Museum of Minorca, located the hypogeum and set about investigating what the cave's original function was.

"On the one hand, a complete photogrammetry of the hypogeum was carried out, which will enable its modelling in 3D and, at the same time, a hypothetical reconstruction of what the hypogeum was like before the various modifications it underwent over time. On the other hand, an archaeological sounding was carried out in the area known as the front courtyard of the hypogeum, an irregularly shaped cavity worked into the rock located in front of the entrance. In addition to locating the place where Joan Flaquer excavated the famous deposit, this exceptional find has been made. In this way, it has been possible to document a part of this intact deposit".

Although these cavities have already been excavated, some recently, they had never expected to find an assemblage with these characteristics. At present, given that the group is in the process of being studied, the specialists point out that this deposit might be part of the funerary rituals of commensality linked to the burials in the hypogeum. This type of practice is very common in other parts of the Mediterranean during prehistoric and classical times, although in Minorca it is the first time it has been documented.

Silver Spitfire completes round the world trip

Silver Spitfire - The Longest Flight logo.

Dec. 7, 2019

A 76-year-old demilitarized aircraft made a 43'500-kilometer journey through some 30 countries before returning to the UK.

A Spitfire landed in the UK on Thursday after a successful world tour, a great first for this iconic symbolic aircraft of the Battle of Britain in 1940. The journey lasted exactly four months.

The silver plane landed at Goodwood Airfield near the southern coast of England. 76 years old and demilitarized, the machine made a journey of 27'000 miles (43'500 km) in thirty countries. He was flown in turn by Steve Brooks, 58, and Matt Jones, 45, two British airmen.

Matt Jones drove it for the final leg of the trip from Lelystad in the Netherlands to the UK. When he got off the plane, he hugged his girlfriend and their newborn son Arthur. During his trip, the pilot and former banker had to return to Russia urgently for the birth.

During his world tour, the Spitfire flew over the Statue of Liberty in New York and the Pyramids of Egypt. He crossed the Atlantic Ocean via the Faroe Islands and Reykjavik, crossing Greenland before flying over the remote wilderness of northern Canada.

In a Texas ranch

In the United States, he stopped for two days on a ranch in Texas after a temperature probe problem and made a stop in the Californian Mojave Desert for a visit to British billionaire Rochard Branson's Virgin Galactic space company. After flying over the North Pacific coast by Canada, Alaska and Russia, the Spitfire ended up in Japan during the typhoons.

He traveled his longest leg in the Saudi desert, a three-and-a-half-hour flight from Kuwait to Akaba in Jordan (1,300 kilometers). He then returned to Britain via Egypt, Greece, Italy, Germany and the Netherlands.

Tribute to the designers

Agile interceptors, the Spitfires played a crucial role in the Battle of Britain, while the United Kingdom fought the threat of an invasion of Nazi Germany.

Neolithic burial chamber discovered in northeastern France

A team from Inrap announced that it has discovered a collective underground burial ground or hypogeum dating to the late Neolithic period in Saint-Memmie, a town in the Marne department of northeastern France, in which about fifty deceased people were buried, during excavations currently being carried out before the creation of a supermarket.

"This hypogeum dating from 3500 to 3000 years BC consists of an entrance opening onto a 3.80 metre long sloping corridor that leads to an antechamber allowing access to the 6 square metre burial chamber through a narrow crawl space," says the National Institute of Preventive Archaeological Research (Inrap) in a statement.

"At this stage, the excavation has revealed several levels of dense and highly intertwined bones. More than forty skulls and about 2,000 bones have already been found in this collective tomb. Some jewellery elements have also been found on the deceased: necklace beads, perforated animal canines used as pendants, flint tools."

The excavation, which is ongoing until the end of November, "will make it possible to refine our knowledge of this funeral practice and the architecture of this type of burial," says Inrap.

Anthropological analysis of the bones will hopefully give a more precise idea of the number of people buried here, their age at time of death, sex, health, and possible familial relationships.
