“Suddenly the sound ceased….

In the distance the rumbling still lingered on for a while, thundering over hills far away, slowly fading to silence, until only the soft rustle of the wind through the leaves remained.


The woods have never been a more quiet place. No birds, no squirrels, only that soft breeze through the trees. As if everything held its breath. Life paused you might say.


Rays of light painted the humid air between the trees in an eerie way. And just in that brief moment between the cataclysmic events everything seemed in complete balance. Life, nature, time and light. If you could press the pause button on time’s tape recorder, all would be fine in that particular moment. Nothing would change and everyone would remain their happy selves for eternity. But there was no button.. Time passed and held no one in regard..


There was a bright flash, a shockwave, bending trees and…..”

MAP LICHEN: It’s ALIVE!


Like many a geologist before him, this lizard sits atop a rock surface totally obscured by the growth of lichen. Though we usually find lichen to be an annoyance that a rock hammer can solve, the lowly lichen properly deserves a greater deal of reverence before we bash it into posterity.

The Sicans are believed to have been traders and skilled artisans whose metallurgy and ceramics featured religious motifs.


The burial practices of the Sican were banned after the arrival of the Spanish conquistadors in the 16th century.

Detectorists find unique Roman bronze hoard in the UK

Detectorists find unique Roman bronze hoard in the UK


A hoard of ancient Roman bronze artefacts discovered in Gloucestershire includes a unique sculpture of a ‘licking’ dog, never found before in Britain – and archaeologists have a fascinating theory about its origins and why it was hidden. The discovery was made by a local metal detectorist who contacted the archaeology team.

The licking dog is an example of a healing statue, and may be linked to the Roman healing temple at Lydney. However there is also the possibility that a previously undiscovered Roman temple may be sited elsewhere in Gloucestershire.

The artefacts appear to have been deliberately broken and hidden – with the exception of the dog statue, which, fortunately, remains intact. Archaeologists believe the items could have been stashed by a metal worker who intended to retrieve them at a later date in order to melt and re-cast them.


The artefacts are of such significance that they need to be kept under special conditions for insurance reasons, and are currently being stored at Bristol museum, where they are being photographed and catalogued on an online database.

Experts are piecing together the clues, and the findings will be presented by the British Museum at a launch event, likely to take place around the end of the year.


Cllr Nigel Moor, cabinet member for fire, planning and infrastructure said: “How wonderful to have made such an astonishing discovery, and what a fantastic coup for Gloucestershire! The prospect of more hidden treasures buried here in the county is an exciting one indeed for local residents and historians alike Congratulations to Pete Cresswell on making this find and fitting another piece into the jigsaw puzzle of Gloucestershire’s rich heritage.”

Finder Pete Cresswell, who discovered the items with his brother in law Andrew Boughton, said: “It’s not every day you come across a hoard of roman bronze! We have been metal detecting for a combined 40 years, but this is a once in a lifetime discovery.


“As soon as I realised the items were of historical significance I contacted the local archaeology team, who were equally excited by the find. It’s a great privilege to be able to contribute to local and British history.”

Archaeologist Kurt Adams, Gloucestershire and Avon Finds Liaison Officer, said: “This Roman hoard dates to the 4th century and mostly contains items that have been deliberately broken, ranging from small vessel fittings to a large bronze statue. Most amazing of all is a complete and finely detailed standing dog statue, which is a unique find for British archaeology.”

Wood sculptures and other relics found at Peru’s Chan Chan site

Wood sculptures and other relics found at Peru’s Chan Chan site


Four wood sculptures —three male and one female— a scepter, metal vessels, textiles and remains of winkles were found at Chayhuac An —probably the first large enclosure at the pre-Columbian adobe city of Chan Chan in northern La Libertad region. The ancient objects were found lying on a funerary platform.

The fourth sculpture was unveiled a few days ago, but archaeologists and conservators are still working to bring the piece to the surface and to provide a contextual interpretation of such discovery.


The carving is 40 cm high and 20 cm wide. It seems to be a male figure holding a cup at chest height. His face is covered with white clay as a mask.

“It is common to find wood figures at Chan Chan, but what matters now is that we have found one right over there [in a funerary context],” archaeologist Cintia Cueva Garcia told Andina news agency.


“We can infer they [figures] were used to mark tombs of important people. We’ve found metal vessels and a body we haven’t yet touched, alongside the sculpture.

Similar individuals have been found at the entrance of other contexts,” she continued.


Another aspect to which considerable importance should be attached is the fact of finding a female sculpture, which is very unusual compared to previous discoveries.

Catching the Shadow of a Neptunian Moon

Catching the Shadow of a Neptunian Moon

NASA & DLR – SOFIA Boeing 747P patch.

Researchers on the flying observatory SOFIA, the Stratospheric Observatory for Infrared Astronomy, are preparing for a two-minute opportunity to study the atmosphere of Neptune’s moon Triton as it casts a faint shadow on Earth’s surface. This is the first chance to investigate Triton’s atmosphere in 16 years.


On Oct. 5, as Triton passes in front of a faraway star it will block the star’s light in an eclipse-like event called an occultation. During the celestial alignment, the team aboard the specially equipped Boeing 747SP aircraft will make observations of the distant star’s light as it passes through Triton’s atmosphere.

Triton has not passed in front of bright stars for many years, making occultation observations difficult. Now, as Triton passes in front of a bright star, the data collected by SOFIA’s 100-inch (2.5-meter) on board telescope and three powerful instruments will enable researchers to better study and characterize the moon’s atmosphere, including its temperature, pressure and density.


Previous observations, including those from NASA’s Voyager 2 spacecraft taken in 1989 and a previous occultation observation in 2001, indicate that Triton’s atmosphere is made mostly of nitrogen and is distorted at different locations by its high winds and strong tides. These new occultation data may also provide details about how the atmosphere varies at different altitudes, enabling researchers to examine if the atmosphere has changed since it was last studied.


Catching a Shadow


Catching Triton’s shadow as it races across Earth’s surface at more than 37,000 mph (17 km/s) while the aircraft is traveling at Mach 0.85 (approximately 652 mph), is no small feat. To ensure that they are in the right place at the right time, researchers have made advanced observations of Triton and the star with multiple telescopes to determine the location of their shadow. From these precise calculations, SOFIA’s flight planners have designed a flight plan that will put the flying observatory in the center of the shadow for approximately two minutes as Triton aligns in front of the star.

“SOFIA is the only observatory able to position itself directly in the shadow’s centerline while avoiding any obscuring clouds,” said Ted Dunham, astronomer from the Lowell Observatory in Arizona and instrument scientist for the High Speed Photometer for Occultations (HIPO). “With the dedicated SOFIA team and three onboard instruments, we can make the precise measurements necessary to study Triton’s atmosphere in great detail.”


Though challenging, SOFIA’s team has previously used this method to make successful observations of Pluto’s atmosphere with SOFIA in 2011 and 2015. Additionally, researchers on SOFIA’s predecessor, the Kuiper Airborne Observatory, discovered Uranus’ rings while studying an occultation by that planet in 1977.


Ground and Air Observations Take Shape


Triton has strong tides because it is close to Neptune, much closer than our moon is to Earth. These powerful tides combined with its strong winds, change the shape of its atmosphere. To measure the overall shape of Triton’s atmosphere, the researchers are also teaming with more than 30 ground-based telescopes across the Eastern United States and Europe. Most of these telescopes are not located where the center of the shadow will fall, but they will make simultaneous observations of different areas of Triton’s atmosphere to get a global view of its shape. The data from across Earth, combined with that collected onboard SOFIA, will help researchers understand how these forces influence the atmosphere.


“The ground-based campaign augments both the visible and infrared data from SOFIA, to give us a global perspective of Triton’s atmosphere,” Kimberly Ennico Smith, SOFIA project scientist at NASA’s Ames Research Center in California’s Silicon Valley.

The center of Triton’s shadow, which is predicted to fall over the Eastern United States, the Atlantic Ocean, and Europe, is far from SOFIA’s home base at NASA’s Armstrong Flight Research Center in Palmdale, California. For this flight, the flying observatory will operate from a temporary base in Daytona Beach, Florida, to complete these observations. From Florida, SOFIA can reach the shadow’s center and return during a single, nine-hour observing flight.

UV-irradiated amorphous ice behaves like liquid at low temperatures



Ice analogs mimicking interstellar ice behave like liquids at temperatures between -210°C and -120°C according to Hokkaido University researchers. This liquid-like ice may enhance the formation of organic compounds including prebiotic molecules and the accretion of dust to form planets.


Molecular bonds in the ice are severed when irradiated by ultraviolet light inside interstellar molecular clouds, facilitating the formation of complex organic substances including prebiotic molecules. Thus, scientists believe interstellar ice to be “cradles” of organic compounds, but little has previously been known about the ice itself.


The team led by Associate Professor Shogo Tachibana of Hokkaido University discovered that ultraviolet-irradiated amorphous ice which mimics interstellar ice exhibited liquid-like behavior at extremely low temperature ranges. This finding should help unravel the mechanisms behind the formation of prebiotic molecules as well as the process that gives birth to planets.


The team sprayed a mixed gas of water, methanol and ammonia onto a substrate which was chilled to -263C/-441F to -258C/-432F and simultaneously irradiated with ultraviolet light. After the ice formed, the researchers turned off the freezer to observe the ice with a microscope as the temperature rose. To their surprise, the ice bubbled like boiling water at temperatures between -210C/-346F and -120C/-184F. Analysis of the gas showed it to be hydrogen molecules, which the researchers believe were formed from methanol and ammonia broken up by UV irradiation. The bubbling shows that the ice was behaving like a liquid, with a viscosity estimated to be similar to that of firm honey.
