The Milky Way Is MOVING Through The Universe At 2.1 MILLION Kilometers Per Hour
The Milky Way Is MOVING Through The Universe At 2.1 MILLION Kilometers Per Hour
Nothing is standing or stationary. As you are reading this, the Earth spins around its own axis; it revolves around the sun, the sun is moving through space at a stunning 792,000 km/h around the gigantic center, and our universe is moving at a mind-boggling 2.1 million kilometers per hour.
You may contemplate that as you are reading this, your body in a stationary position. But, everything inside the universe travels, from our planet (Earth) –which revolves on its axis at a speed of approximately 1700 km/h— to the solar system and even the Milky Way Galaxy.
All the planets in the solar system and their personal moons also travel through space. Actually, in order to retain a stable orbit, it is essential for Earth to move around 30 km/s. The innermost planets in our system, Mercury and Venus travel faster while planet Mars and the external planets of our solar system fly through space at a sluggish pace.
But think superior and bigger. Even yet the Sun is at the heart of our solar system, it is also travelling at an unbelievable speed through space.
If we consider even bigger, we will understand that even our gigantic Milky Way galaxy is in motion, and all continuing things that make up the universe such as stars, gas clouds, planets, black holes and even the mighty dark matter travel within the universe.
Just as Earth revolve around the Sun and our Sun revolves the galactic center –which from our vantage point is situated around 2500 light-years away— in an elliptic trajectory. It finishes a revolution every 225 million years roughly. This is known as a Galactic year.
It is predicted that since the Sun and Earth came into being, 20 galactic years have passed, which means that we ended 20 successful revolutions orbiting the galactic center. However, if we relate detailed human history to our movement through the universe, we would understand we hardly moved in our galactic path.
But what about the Speed? In order to finish a successful revolution around the galactic center, the Star (Sun) has to travel at a stunning speed of 792,000 km/h. Including Earth and all other objects in our complete solar system follow the sun at this obsessive speed.
In comparison, light-travels at a mesmerizing speed of 1.09 BILLION km/h.
Though, not only do moons, planets, and in this particular case, our sun travels through space, the galaxy also moves through space, pushed by the gravitation of other enormous objects in the universe.
As it turns out, our Galaxy is now being thrown, by other huge galaxies and clusters in the surrounding area — near a certain point in the universe.
But wait a minute, related to WHAT is we actually calculating the movement through the universe? Well, when arguing our speed around the Milky Way Galaxy, researchers are capable to measure it relative to the HEART of the Milky Way Galaxy.
However, the Milky Way Galaxy isn’t motionless or stationary, and it also moves through the universe. So is there anything to which its motion can be compared?
For a long period time, astronomers and scientists were not able to answer any questions like this. We can compare our galaxy’s speed with other galaxies, but all the other galaxies travel through the universe just as the Milky Way Galaxy does.
In order to answer this mystery, astronomers and scientists point towards the CBR (Cosmic Background Radiation) and the Big Bang.
As stated by NASA, The Big Bang theory guesses that the early universe was an extremely hot place and that as it grows; the gas within it gets cooler. Therefore the universe should be packed with radiation that is exactly the remnant heat left from the Big Bang, called the “Cosmic Microwave Background,” or CMB. The Cosmic Microwave Background (CMB) radiation was produced 13.7 billion years ago.
Theoretically speaking, the CBR suggests experts with a frame of reference for the entire universe, compared to which we can determine and calculate our motion.
In order to get knowledge of how fast we’re travelling through the universe, astronomers need to take away the motion of planet Earth around the Sun and the Sun around the center of the Milky Way from the movement measured compared to the Cosmic Microwave Background (CBR).
This means that the Milky Way Galaxy is travelling through space at an amazing speed of 2.1 million km/h, in the direction of the constellations of Virgo and Leo; exactly where the so-called Great Attractor is situated.

New Observations Confirm That a Magnetar has a Solid Surface and No Atmosphere
Atmosphere
Can a star have a solid surface? It might sound counterintuitive. But human intuition is a response to our evolution on Earth, where up is up, down is down, and there are three states of matter. Intuition fails when it confronts the cosmos.
Magnetars are dead stars with intense magnetic fields, the most intense we know of. They’re a type of neutron star, the stellar remnants of a massive star that exploded as a supernova. Magnetars are not only highly magnetized compared to neutron stars, but they also rotate more slowly. While a magnetar might rotate once or twice every ten seconds, a neutron star can rotate as fast as ten times each second.
Magnetars are one of those cosmic objects that scientists deduced must have existed long before they found one. They were invoked to explain the existence of transient gamma-ray sources called soft gamma repeaters (SGRs.) The hypothesis is that as a magnetar’s intense magnetic field slowly decays, it will emit gamma rays and x-rays. It takes about 10,000 years for the field to decay. Now we know of at least 31 magnetars, and researchers calculate that there are about 30 million inactive magnetars in the Milky Way.
Magnetars emit powerful x-rays and undergo erratic bursts of activity. A magnetar’s bursts and flares can emit in a single second what our Sun needs an entire year to emit. The extreme magnetic fields are responsible for this behaviour, scientists think, and they can be up to one thousand times more powerful than the magnetic fields around neutron stars.
A new study says that one of these magnetars has a solid surface and no atmosphere. It’s called 4U 0142+61, and it’s about 13,000 light years away from Earth in the Cassiopeia constellation. The study is “Polarized x-rays from a magnetar,” and it’s published in the journal Science. The lead author is Dr. Roberto Taverna, from the University of Padova (Padua), Italy.
“The star’s gas has reached a tipping point and become solid in a similar way that water might turn to ice. This is a result of the star’s incredibly strong magnetic field.”
Co-lead author Professor Silvia Zane, UCL, IXPE science team member.
A spacecraft launched in December 2021 made this study possible. The Imaging X-ray Polarimetry Explorer (IXPE) is a joint mission between the Italian Space Agency and NASA. As the name makes clear, the spacecraft observes the polarisation of x-rays. Exotic objects like black holes, pulsars, neutron stars, and magnetars all have extreme environments that polarise x-rays. IXPE can observe these x-rays and provide insights into the objects and their environments. Understanding the exotic, powerful magnetic fields around magnetars is one of IXPE’s explicit objectives.

As this study shows, it’s paying dividends.
This study marks the first time that scientists have observed polarised x-rays from a magnetar. IXPE observed the magnetar for a total of 840 kiloseconds (about 233 hours) in January and February of 2022. What did those observations show?
First, a bit about polarised light.
Most of the light we encounter is non-polarized. That means that as the light travels, it “vibrates” in multiple planes and travels outward in multiple directions. Sunlight, electric light, and a candle flame all emit non-polarized light.
Polarized light is light that vibrates in only one plane. You’ve probably worn polarized sunglasses at one time or another. They reduce glare by filtering out light vibrating on other planes and only allowing aligned light to reach your eyes.
Since light, including x-rays, is electromagnetic energy, extremely powerful magnetic fields around magnetars can polarise light. By measuring the degree of polarity, scientists can make deductions about the magnetic fields and the objects generating them. That’s at the heart of IXPE’s mission and at the heart of this study. IXPE has three identical imaging X-ray polarimetry systems that operate independently for redundancy. IXPE creates polarization maps that reveal the structure of the magnetic fields around objects like magnetars.

As the paper’s one-sentence summary says, “The IXPE observation of 4U 0142+61 gives the first ever measurement of polarized emission from a magnetar in x-rays.”
The researchers found a much lower proportion of polarised light than there should be if the x-rays had passed through an atmosphere. An atmosphere around the magnetar would act like a filter and allow only one polarisation state of light to pass through.
The team also found that the wiggle, or angle of polarisation, flipped exactly 90 degrees for higher energies when compared to lower energies. Theoretical models of magnetars state that a solid surface surrounded by magnetic fields can produce these observations.
“The most exciting feature we could observe is the change in polarisation direction with energy, with the polarisation angle swinging by exactly 90 degrees,” said lead author Taverna. “This is in agreement with what theoretical models predict and confirms that magnetars are indeed endowed with ultra-strong magnetic fields.”
“This was completely unexpected,” said co-lead author Professor Silvia Zane (UCL Mullard Space Science Laboratory) and a member of the IXPE science team. “I was convinced there would be an atmosphere. The star’s gas has reached a tipping point and become solid in a similar way that water might turn to ice. This is a result of the star’s incredibly strong magnetic field.”
“But, like with water, temperature is also a factor – a hotter gas will require a stronger magnetic field to become solid,” added Zane. “A next step is to observe hotter neutron stars with a similar magnetic field, to investigate how the interplay between temperature and magnetic field affects the properties of the star’s surface.”
Quantum theory plays a role in these findings. It predicts that when light is propagated in a highly magnetized environment, it’ll be polarized in two directions: parallel to the magnetic field lines and perpendicular to them. By observing both the polarity of the light and the amount of light, scientists can understand the structure of the magnetic field itself, which imprints itself on the light and on the physical state of the matter in the region of the magnetar. According to the study, this is the only way to access that information.
Magnetars can have complex magnetic fields, and IXPE is a powerful tool for observing them. IXPE creates polarization maps of objects like magnetars which is the only way to reveal their structure.

Professor Roberto Turolla from the University of Padova is another of the paper’s co-authors. In a press release, Turolla said, “The polarisation at low energies is telling us that the magnetic field is likely so strong to turn the atmosphere around the star into a solid or a liquid, a phenomenon known as magnetic condensation.”
Theory also predicts that this solid surface is made of ions held together in a lattice by magnetic fields. Rather than spherical like other atoms, these ones would be elongated due to the powerful magnetic force.
Scientists still debate whether or not magnetars and other neutron stars can even have atmospheres. There’s a ton of mystery surrounding these extreme objects and their confounding nature. But at least we know of one magnetar that has no atmosphere, or at least where a solid crust is a suitable explanation.
But the explanation still needs more scrutiny, say the authors.
“It is also worth noting that including quantum electrodynamics effects, as we did in our theoretical modelling, gives results compatible with the IXPE observation,” said co-author Professor Jeremy Heyl of the University of British Columbia. “Nevertheless, we are also investigating alternative models to explain the IXPE data, for which proper numerical simulations are still lacking.”

The Sun Could Hurl Powerful Storms at us from its Goofy Smile
Our Sun is the very reason we’re alive. It provides warmth and the energy our planet needs to keep going. Now you can add photogenic to its illustrious résumé, as NASA recently photographed our giant ball of nuclear fusion doing something quite peculiar.
“Say cheese!” NASA Sun & Space (@NASASun) tweeted on October 26th. “Today, NASA’s Solar Dynamics Observatory caught the Sun “smiling.” Seen in ultraviolet light, these dark patches on the Sun are known as coronal holes and are regions where fast solar wind gushes out into space.” These dark patches are also known as sunspots, which can reach approximately 3600 degrees Celsius (6500 degrees Fahrenheit), and are responsible for radiation-filled solar flares that can wreak havoc on a planet.
This phenomena is also known as space weather, and thankfully, our own planet has a protective magnetic field that deflects the solar flares to both the north and south poles, resulting in the beautiful auroras seen by many. Even with this field, solar storms can sometimes be powerful enough to create chaos with both satellites and worldwide electrical grids, causing communication delays and even blackouts.

It turns out this isn’t the first time our Sun has made faces at us, as NASA’s Solar Dynamics Observatory, or SDO, imaged the Sun depicting a jack-o-lantern’s face back in October 2014, which made for a spooky pre-Halloween treat for astronomy lovers.

In terms of size, our Sun is approximately 100 times wider than the Earth, meaning dozens of Earths could snugly fit inside the Sun’s recent “smile”, which is a humble reminder that while our Sun is responsible for both life and displaying familiar surface features from time to time, it can also be responsible for immense death and destruction, as well.
Maybe our Sun smiling at us is a sign that it wants us to stick around for a while, but if we capture it giving us a frown, then maybe it’s time to panic.

Guys, check this out. I discovered this back in 2010, but I have often thought deeply about it and really wanted to talk about it more. I thought it was photoshop by NASA, but more and more I am believing that this is a space station. The link still works and NASA actually labels it "photo of the day." It should be photo of the millennium because this is a huge and historical discovery about Dione and Titan. They are space stations, the back of Dione has huge finger like structures coming out of it. Dark structures so that they could not be detected from far away. The auto of colors around those dark fingers indicated a thriving civilization within them...the reds, pinks and greens could only be coming from a technological intelligent species.

IN DE RUIMTE BEVINDT ZICH DIT ENORME 'KATTENOOG' EN HET BLIJKT EEN VERRASSING TE HERBERGEN
Vivian Lammerse
Dat de beroemde Kattenoognevel een vreemde eend in de bijt is, wisten astronomen al langer. Maar nu begrijpen ze ook waarom.
De Kattenoognevel is een planetaire nevel, die met wat fantasie op het oog van Sauron lijkt. De meeste planetaire nevels zijn vrij recht-door-zee, maar dat geldt niet voor de Kattenoognevel. Deze nevel bestaat uit een ingewikkelde structuur van knopen en structuren, boogachtige filamenten en concentrische gasschillen. Niet voor niets is de Kattenoognevel één van de meest complexe planetaire nevels die we kennen. Onderzoekers hebben nu voor het eerst een driedimensionaal model van de Kattenoognevel vervaardigd. En die verraadt hoe hij zijn opvallende voorkomen heeft gekregen.
Planetaire nevel Een planetaire nevel ontstaat wanneer een stervende, zonachtige ster zijn buitenste gaslaag wegslingert. Hierdoor wordt er en kleurrijke ‘schil’ gevormd die kenmerkend is voor dergelijke objecten. Maar zoals gezegd is de Kattenoognevel – een planetaire nevel op iets meer dan 3000 lichtjaar afstand van de aarde, te zien in het sterrenbeeld Draak – een vreemde eend in de bijt. De mysterieuze structuur van de nevel heeft astrofysici al eerder in verwarring gebracht. Zo blijkt dat zijn raadselachtige voorkomen niet kan worden verklaard door eerder aanvaarde theorieën over de vorming van planetaire nevels.
3D-model Onderzoeker Ryan Clairmont besloot een verwoede poging te wagen om de mogelijke mechanismen die de Kattenoognevel zijn vorm hebben gegeven, te ontraadselen. Daarvoor schakelde hij de hulp in van het het San Pedro Martir National Observatory in Mexico. Spectrale gegevens vervaardigd door dit observatorium verschaffen namelijk inzicht in de interne beweging van materiaal in de nevel. Samen met gegevens en afbeeldingen van de Hubble-ruimtetelescoop construeerde Clairmont vervolgens een gedetailleerd 3D-model.
De Kattenoognevel. Links: het nieuw vervaardigde 3D-model. Rechts: Een eerder gemaakte foto van Hubble.

Het 3D-model onthult ringen van gas die rond de buitenste schil van het Kattenoog cirkelen. Verrassend genoeg zijn deze gasringen bijna perfect symmetrisch ten opzichte van elkaar gepositioneerd. En dat is interessant. Deze symmetrie suggereert namelijk dat de gasringen zijn gevormd door een jet – een stroom van gas – die in tegengestelde richtingen werd uitgestoten vanuit een centrale ster.
Dubbelster Volgens de onderzoekers vertoonde deze jet een zogenoemde ‘ precessie-beweging’. Het eenvoudigste voorbeeld van precessie is een draaitol die op de grond ronddraait. En dat verraadt dat de centrale ster waarschijnlijk vergezeld is door een andere ster. Dat komt omdat bekend is dat alleen dubbelsterren zogenaamde ‘precesserende’ straalstromen in planetaire nevels kunnen aandrijven. Kortom, in het hart van de Kattenoognevel houdt zich vermoedelijk een dubbelster op.
De studie werpt nieuw licht op de raadselachtige vorm van de Kattenoognevel. Zo denken de onderzoekers dat de hoek en de richting van de jet in de loop van de tijd veranderde. En op deze manier zagen vervolgens alle opvallende kenmerken van de nevel het levenslicht. Daarnaast breidt het onderzoek ook onze kennis over planetaire nevels in het algemeen uit. “Precesserende jets in planetaire nevels zijn relatief zeldzaam,” zegt Clairmont. “Het is daarom belangrijk om te begrijpen hoe ze bijdragen aan de vorming van complexere systemen zoals de Kattenoognevel. Uiteindelijk zal dit ook inzicht verschaffen in het uiteindelijke lot van onze zon, die op een dag zelf een planetaire nevel zal worden.”
WETENSCHAPPERS VINDEN MYSTERIEUZE 'BLAUWE SMURRIE' OP DE BODEM VAN DE OCEAAN EN HEBBEN GEEN IDEE WAT HET IS
WETENSCHAPPERS VINDEN MYSTERIEUZE 'BLAUWE SMURRIE' OP DE BODEM VAN DE OCEAAN EN HEBBEN GEEN IDEE WAT HET IS
Caroline Kraaijvanger
Ideeën? Iemand?
Wetenschappers spotten de mysterieuze ‘blauwe smurrie’ tijdens een expeditie naar de Mid-Atlantische Rug; een grotendeels onder water gelegen bergketen in de Atlantische Oceaan. Onder meer met behulp van onderwaterrobots werd het gebied rondom deze keten – en het leven dat daar te vinden is – nader in kaart gebracht. Voorafgaand aan de expeditie verwachtten onderzoekers daarbij onder meer op diepzeekoraal en sponzen te stuitten, maar verrassingen waren zeker niet uitgesloten.
Blauwe smurrie En zo’n verrassing heeft zich nu dus aangediend in de vorm van wat de onderzoekers zelf ‘blauwe smurrie’ noemen. De ‘smurrie’ is op verschillende plekken voor de kust van de Amerikaanse Maagdeneilanden – op enkele honderden meters diepte – aangetroffen. En onderzoekers hebben geen idee wat het is.
Het zou een zacht koraal kunnen zijn, merkt één van de onderzoekers in bovenstaande video op. Maar, zo benadrukt een ander, we weten het nog niet. Het zou bijvoorbeeld ook een soort spons kunnen zijn. Of een soort manteldier. “Ik denk dat het een mysterie blijft, tot we het kunnen bemonsteren,” stelt één van de onderzoekers. Of tot een deskundige het op basis van de vrij scherpe beelden kan identificeren.
Gaten Het is zeker niet het eerste mysterie dat de expeditie naar Mid-Atlantische Rug voortbrengt. Zo stuitten onderzoekers eerder al op tamelijk mysterieuze gaten in de zeebodem waarvan nog altijd onbekend is hoe ze tot stand komen.
De nog altijd onverklaarbare gaten in de zeebodem die onderzoekers eerder aantroffen.

En ook kwamen wetenschappers tijdens de expeditie een zeer zeldzame vergadering van zee-egels tegen. Onderzoekers zijn er nog maar zelden getuige van geweest dat zee-egels het gezellig maken samen. Maar wat de ontmoeting nog bijzonderder maakte, is dat alle verzamelde zee-egels zichzelf een ‘hoedje’ van puin hadden aangemeten. Waarom de zee-egels elkaar ontmoetten en waarom ze daarbij allemaal een hoedje op hadden, is nog altijd onduidelijk.
Eerder stuitten de onderzoekers tijdens de expeditie ook al op een zeldzame vergadering van zee-egels, waarbij alle verzamelde zee-egels ook nog eens een mysterieus ‘hoedje’ droegen.
Afbeeldingen: NOAA Ocean Exploration, Voyage to the Ridge 2022.
Zoveel onbekend De mysterieuze ontdekkingen op de bodem van de oceaan geven wel aan hoe belangrijk het is dat er meer onderzoek naar onze oceanen wordt gedaan. De oceaanbodem is nog tamelijk onontgonnen terrein; hoewel de oceaan zo’n 70 procent van het aardoppervlak bestrijkt, is slechts 20 procent van de wereldwijde zeebodem tot op heden in kaart gebracht. En ook de organismen die op de bodem en in de (dieper gelegen) wateren leven, hebben nog behoorlijk wat geheimen voor ons.
Langste bergketen Dat geldt zeker ook voor het gebied waar de beelden van de blauwe smurrie en mysterieuze gaten zijn gemaakt; de Mid-Atlantische Rug is met een lengte van 16.000 kilometer de langste bergketen op aarde, maar deze onder water gelegen berg en omgeving zijn nog nauwelijks bestudeerd. Wetenschappers probeerden daar recent daar tijdens een serie expedities – die samen aangeduid worden als ‘Voyage to the Ridge 2022‘ verandering in te brengen. Vanaf het onderzoeksschip Okeanos Explorer werd de Mid-Atlantische Rug en omgeving met sonarapparatuur in kaart gebracht, terwijl onderwaterrobots een inkijkje gaven in wat er allemaal in het gebied leeft. Want pas als we dat weten, kunnen we de ecosystemen gaan monitoren en eventueel ingrijpen als een ecosysteem – bijvoorbeeld door inmenging van mensen – in de knel dreigt te komen.
Eerder deze maand kwam de laatste van de serie expedities naar de Mid-Atlantische Rug ten einde. De komende tijd zal de sonardata gebruikt worden om de – nog altijd flinke – gaten in onze kaarten van de wereldwijde zeebodem te helpen opvullen. De onderzoekers leveren zo een bijdrage aan Seabed 2030: een project dat erop gericht is om de complete zeebodem tegen 2030 in kaart te hebben gebracht. Daarnaast zullen ook de door onderwaterrobots gemaakte beelden ongetwijfeld verder worden uitgeplozen. Of het tot identificatie van de nu nog mysterieuze blauwe smurrie zal leiden, is afwachten. Vaststaat dat de data leidend zal zijn voor het plannen van nieuwe expedities naar de bodem van de oceaan. Want wat alle vergaarde gegevens vooral laten zien, is dat er nog heel veel is wat we niet weten of in ieder geval slecht begrijpen.
Archaeologists sυrveyiпg the world’s oldest sυbmerged towп have foυпd ceramics datiпg back to the Fiпal Neolithic. Their discovery sυggests that Pavlopetri, off the soυtherп Lacoпia coast of Greece, was occυpied some 5,000 years ago — at least 1,200 years earlier thaп origiпally thoυght.
These remarkable fiпdiпgs have beeп made pυblic by the Greek goverпmeпt after the start of a five-year collaborative project iпvolviпg the Ephorate of Uпderwater Aпtiqυities of the Helleпic Miпistry of Cυltυre aпd The Uпiversity of Nottiпgham.
As a Myceпaeaп towп, the site offers poteпtial пew iпsights iпto the workiпgs of Myceпaeaп society. Pavlopetri has added importaпce as it was a maritime settlemeпt from which the iпhabitaпts coordiпated local aпd loпg-distaпce trade.
The Pavlopetri Uпderwater Archaeology Project aims to establish exactly wheп the site was occυpied, what it was υsed for aпd throυgh a systematic stυdy of the geomorphology of the area, how the towп became sυbmerged.
This sυmmer the team carried oυt a detailed digital υпderwater sυrvey aпd stυdy of the strυctυral remaiпs, which υпtil this year were thoυght to beloпg to the Myceпaeaп period — aroυпd 1600 to 1000 BC.
The sυrvey sυrpassed all their expectatioпs. Their iпvestigatioпs revealed aпother 150 sqυare metres of пew bυildiпgs as well as ceramics that sυggest the site was occυpied throυghoυt the Broпze Age — from at least 2800 BC to 1100 BC.
The work is beiпg carried oυt by a mυltidiscipliпary team led by Mr Elias Spoпdylis, Ephorate of Uпderwater Aпtiqυities of the Helleпic Miпistry of Cυltυre iп Greece aпd Dr Joп Heпdersoп, aп υпderwater archaeologist from the Departmeпt of Archaeology at The Uпiversity of Nottiпgham.
Dr Joп Heпdersoп said: “This site is υпiqυe iп that we have almost the complete towп plaп, the maiп streets aпd domestic bυildiпgs, coυrtyards, rock-cυt tombs aпd what appear to be religioυs bυildiпgs, clearly visible oп the seabed. Eqυally, as a harboυr settlemeпt, the stυdy of the archaeological material we have recovered will be extremely importaпt iп terms of revealiпg how maritime trade was coпdυcted aпd maпaged iп the Broпze Age.”
Possibly oпe of the most importaпt discoveries has beeп the ideпtificatioп of what coυld be a megaroп — a large rectaпgυlar great hall — from the Early Broпze Age period.

“Intriguing” Prehistoric Silver Jewelry in Omani Tomb Evidence of Regional Trade
“Intriguing” Prehistoric Silver Jewelry in Omani Tomb Evidence of Regional Trade
Several important archaeological discoveries that shed light on ancient trade settlements in the Oman region have been unearthed by nearly a decade of excavations at a site from the early Bronze Age in Oman.
This list includes the remains of floorplans, warehouses, administrative buildings, ritual buildings, a tomb, industrial infrastructure for processing copper ore, and silver jewelry dated to the 3rd millennium BC. The jewelry includes parts of beautiful necklaces with beads, spacers, and silver rings from the Umm-al Nar culture’s zenith, including one particularly interesting ring that highlights the complexities of global trade in the ancient world.
International Team Uncovers Umm-al Nar Sites
The joint American and Omani mission was recently announced on the sidelines of the International Conference on Archaeology and Arts in South Asia, in Barcelona, Spain. According to a press release by Oman’s Ministry of Heritage and Tourism, the team was headed by Prof. Dr. Nasser Al-Jahuri and Dr. Khaled Douglas from the Department of Archaeology at Sultan Qaboos University. They were assisted by Professor Kimberly Williams from Temple University Philadelphia, USA, who excavated the especially interesting tomb.
Explaining the importance of the site, Professor Nasser al-Jahuri, who discovered the site, said, “The archaeological site of Dahwa is considered among the important early Bronze Age sites in the Al-Batinah Plain due to the nature and quantity of archaeological finds that were uncovered during the various seasons of survey and excavation, which started in 2013 and continued until 2021. In 2013, the department began its field work by conducting a comprehensive archaeological survey in the Dahwa region, where five distinct archaeological sites were discovered that include ancient settlements dating back to the so-called Umm al-Nar culture (2600-2000 BC)".
The site, titled Dahwa 7, also included a mass grave , which ended up being the only grave found at the site. The grave yielded a large number of local and imported pottery items, among other important items.
A Prehistoric Silver Ring Illuminating Ancient Trade Networks
The fascinating tomb includes skeletal remains, as well as imported and local pottery and jewelry, including a distinctive seal on a silver ring belonging to the Harappan civilization. The seal depicted a bison from the Indus Valley, which lay a few hundred kilometers away in what constitutes modern-day India and Pakistan, Canada Today reported.
According to Dr. Dennis Frienz, an Italian expert on ancient trade routes between the Indus Valley and Oman, and a collaborator with the Omani Ministry of Heritage and Tourism: “The discovery of a silver ring in a tomb in North Al Batinah is likely to have been made in Mesopotamia (Iraq) using Anatolian silver (Turkey) for an individual associated with foreign trade with the Indus civilization (Pakistan and Western India) shows the great development of foreign trade, interaction and trade and cultural relations in prehistoric Eurasia, which can certainly be considered a prototype of modern global exchanges.”
What is most fascinating was the extent of the globalization the ring demonstrates. This provides additional evidence for the diversity and interconnectedness of ancient civilizations, considering that similar rings were found in Iran, Mesopotamia, and Bahrain as well. Moreover, those similar rings have been dated to later periods according to Jonathan Mark Kenoyer, professor of anthropology and archaeology from the University of Wisconsin-Madison, USA.
The trade links are also gleaned from the quality of the seal’s decorative pattern and its distinctive shape, which are quintessentially Harappan. Another peculiarity is the fact that previously found seals were on smooth stone, but this is the first time that a bison image has been found on a metal ring, reported The Oman Observer . In 2020, bison stamp seals of local softstone were found at Salut and Al-Moyassar in Oman.
The bison image on this prehistoric silver ring found in Oman was typical of Harappan culture, indicating ancient global trade networks.
This suggests that the people of the Umm al-Narr culture were more intelligent and technologically advanced than previously thought. “… they introduced at a very early stage, administrative solutions that allowed economic growth in the later millennia,” he concluded.

In a new documentary, pilots reveal chilling details about the alleged sightings of UFOs
Sergeant Sérgio Mota da Silva
The latest film based on the Night of the UFOs follows a Brazilian fighter pilot who came across a UFO in 1986. In the audio clip, the pilot talks about his frightening encounter with the object.
On May 19, 1986, various people reported seeing over 20 unidentified objects flying across Brazil. These sightings were reported in different areas such as Rio de Janeiro, Sao Paulo, and Minas Gerais.
One night in 1986 UFOs swarmed over Brazil
The Brazilian Air Force immediately launched fighter jets to intercept the objects. However, the pilots were reportedly left disoriented by the objects and did not have a clear explanation as to why they saw them. According to reports, five of the country’s fighter pilots saw up to 21 objects disappear.
A documentary about the incident features a radio message that one of the pilots sent to the control tower.
The audio of the incident was played in the film. It captured the moment the pilot first encountered the object. In a chilling audio, he can be heard saying, “It’s not an airplane, what is it?”
Brazilian photographer Adenir Britto was able to capture the various objects in the sky during the incident.
In a radio message, the fighter pilot noted that there were three objects in the sky. He then asked the control tower to identify the objects. The pilot was confused by the objects and noted that one of them flew in front of Mike-Bravo-Zulu, a radio station. The short clip, which was released by James Fox, featured the pilot’s voice.
The Night of the UFOs was not the first time that a documentary explored the subject. The pilots noted that the objects moved at speeds of up to 11,500 mph. They did not appear on radars.
Local newspaper report of the incident, 1986
The Night of the UFOs documentary was significant as it highlighted the seriousness of the issue, as well as the number of officials around the world who are investigating the possibility of UFOs. In May, the US held a public hearing regarding the issue.
On June 24, the Senate of Brazil held a special session in observance of the 75th anniversary of the UFO Day. It was attended by various UFO enthusiasts and experts.
The number of reported sightings of UFOs has significantly increased worldwide. In just over a year, the number of incidents reported in the US increased from 143 to 400. Reports of these sightings have also increased in other countries such as China and Russia.

On the night of the incident, a sergeant working at an airport in Brazil said he saw a light in the sky. He then alerted the control tower. This event, which started the Night of the UFOs, happened at around 8 pm.
Thrilled by the strange activity, Mota approached the control tower of the airport in Brazil’s Sao Paulo to see if an aircraft was flying toward his facility. The control tower did not respond to his query, and the object disappeared.
After a while, the object reappeared. According to Mota, he was able to see it through binoculars, and he found it strange and multi-colored. In an interview with the BBC, he said that he didn’t know if the objects were trying to interact with him.
Three fighter jets were immediately launched. One of these was a Mirage F-103 aircraft piloted by Captain Armindo Sousa Viriato. The pilot noted that as he was about to approach the object, it accelerated to speeds of over 11,500 mph.
After the Night of the UFOs incident, many pilots admitted that they were not aware of what they were witnessing. They were then assigned to identify the objects.
Unfortunately, they were not able to identify the objects due to their fast moving nature. According to a report by the Sun, a pilot from Brazil’s air force said that he was only able to see the objects through visual contact.
In May, Brigadier-General Octavio Moreira Lima, the Minister of Aeronautics, held a press conference to explain the incident. He said that the five fighter jets that were deployed chased over 21 unidentified objects. However, he refused to provide additional details about the nature of the objects or the pilots involved.
Due to the number of people who reported witnessing the incident, the Night of the UFOs incident has been regarded as the most popular talking point regarding the sightings of UFOs in Brazil.
The interest in UFOs grew following the US Congressional hearing on the subject in May. Governments from China and Russia also announced their investigations into the matter. This marked the first time in over 50 years that the US Congress held a hearing on the subject of UFOs.
This Brazilian farmer “may be first in world to be killed by UFO”
This Brazilian farmer “may be first in world to be killed by UFO”
Local newspaper report about this strange event
According to this book (Amazon link), a farmer may have been the first person in the world killed by a UFO.

Luis Barroso Fernandes, a Brazilian, died mysteriously after claiming that he was attacked by small extraterrestrials that came out of a “strange disc”.
Philip Mantle, a British investigator, believes that the incident that led to the death of Luis Barroso Fernandes could be the first case of a UFO killing a person.
According to the book, Luis said he heard a buzzing sound and spotted an unidentified object in the sky.
He claimed that the object was about 30 meters from him when it hit the ground. He then said that two small alien creatures came from it.
Luis Barroso Fernandes
He said that the creatures attacked him and his donkey, causing them to become paralyzed. He woke up to find that he was several meters away from the object. He also had burn marks on his face.
After finding the farmer, a cowboy took him to his wife, who then called the doctors. They reportedly could not diagnose his strange condition.
After hearing the farmer’s story, Dr. Antnio Moreira Magalhes, a psychiatrist, concluded that the incident was very serious. Although he didn’t believe in flying saucers at that time, he admitted that something happened to the farmer.
Following the incident in 1973, the doctor ordered a tranquilizer and an anti-allergy drug for the farmer.

Despite the treatment, Fernandes still felt ill. His body continued to hurt. His left side of his body was still red, and burning eyes were still visible.
The book also stated that after the incident, his hair started to fall grey and he had memory lapses. Although his friends and family claimed that he was in good health before the alleged incident, his health started to deteriorate.
His relatives took him to a psychiatric hospital. According to the book, 16 doctors examined him, but none of them could diagnose his condition.
After learning about the incident, Dr. Magalhes carried out his own investigation and diagnosed Fernandes’ worsening mental condition.
Fernandes died in 1993. Before his death, he could barely utter the words “Mom,” “give,” and “fear.” A couple of students, a radio broadcaster, and military personnel also reported seeing a UFO over the city that same day.
Philip Mantle, a former official of the UFO Research Association, has written a book about the incident.
According to him, many people claimed to have been in direct contact with the extraterrestrial creatures. Some also stated that the objects hurt them.
Although the book states that there were minor injuries on Fernandes’ body, he most likely became the first person to die after being attacked by a UFO.
Author of the book Thiago Ticchetti stated that contact with extraterrestrials is rare. He noted that when objects shoot a beam of light at an individual, it is extremely rare for them to hit their face.
In addition, Brazil has a huge amount of uranium that it can sell to Iran for its nuclear program. This could be the reason why there’s a lot of UFO and alien activity in the country.

15 Real Things That Defy the Laws of Physics!
You don't have to be an Einstein to understand the basic laws of physics. Since objects always fall downwards, more precisely in the direction of the center of the earth, we can look forward to a nice heap of broken glass as soon as a cup slips out of our hands - thank you very much, physics. But have you ever heard of waterfalls that flow up instead of down? Or objects that start to float as if by magic? You want to know what these almost unbelievable cases are all about? Then stay tuned and see for yourself: Here are several amazing things that defy the laws of physics!

Plus: Worm spit could annihilate plastic.
Scientists are betting that the wax worm’s saliva can help cut down on plastic pollution by breaking down PE plastic.
Simona Gaddi
Plastic pollution is a huge problem worldwide: We produce around 350 to 400 million tons of non-degradable plastic annually, and 5 to 13 million tons end up in the ocean. But we don’t yet have many sustainable, cost-effective recycling methods yet.
A promising technique called biodegradation could add a crucial tool to our recycling toolbox: Scientists have deployed organisms like bacteria and fungi to break down plastic, but it can take months and require pre-treatment that demands loads of energy.
Now, findings suggest that the saliva from the beeswax-eating wax worm, or Galleria mellonella, could be harnessed to break down the world's most widely used plastic (polyethylene or PE), according to a new study published in the journal Nature Communications. The method doesn’t require any treatment beforehand, saving time and money.
Researchers from Spain studied wax worm larvae saliva and found that it can degrade PE by breaking it down into smaller molecules. The process only takes a few hours. To the best of the researchers’ knowledge, this is the quickest biodegradation technique yet for PE.
Study author Federica Bertocchini, a molecular biologist at the Spanish National Research Council, hopes the new study can inspire other labs to go after similar research.
“We also hope that the study might increase the study of insects as the wonderful resourceful animals they are, both as a biotechnological tool, but, even more, at the basic research level,” she adds.
YOU MAY HAVE seen clips of the creepy, dog-like robot from Boston Dynamics called Spot that can traverse rough terrains, map its environment, and grab you a drink, among other skills. The company has even programmed Spot to dance to K-pop.
Spot and other roving autonomous bots developed in recent years have received lots of criticism as they’ve been increasingly embraced by law enforcement officials. Some experts worry that the AI programmed into these robots could target people of color or use excessive violence. Last year, public concern forced the NYPD to retire a Spot model that they called Digidog.
It’s also possible for ordinary people to use commercially available robots for evil: This summer, a Russian man terrified the internet when he slapped a gun onto a Unitree dogbot.
Now, Boston Dynamics and other robotics companies seem eager to clean up their image.
WHAT’S NEW — In an open letter published last week, six major robotics companies have promised not to weaponize their publicly available devices and software — and not to support anyone doing so — as originally reported by Axios. These include Agility Robotics, which is working on a hyped-up humanoid called Digit (that will come with a face and hands).
While the letter notes that “advanced mobile robots will provide great benefit to society as co-workers in industry and companions in our homes,” the automation giants do point out the potential for mistreatment.
“We believe that adding weapons to robots that are remotely or autonomously operated, widely available to the public, and capable of navigating to previously inaccessible locations where people live and work, raises new risks of harm and serious ethical issues,” they add.
The Spot robot from Boston Dynamics has appealed to law enforcement officials in recent years.

THERE’S A CATCH
This oath doesn’t seem to apply to the devices used by military and police officials. That’s not a huge surprise, since Boston Dynamics largely got its start with funding from the military, along with the controversial Defense Advanced Research Projects Agency (DARPA).
In fact, U.S. Marine Corps officials have already looked into using Boston Dynamics’ AlphaDog robot in combat, but they shelved it in 2015 because it proved too loud for the battlefield. They have also tried to prep the company’s human-like Atlas model for battle.
Governments around the world also want to automate their armies. For instance, the French army has tested Spot for surveillance purposes, according to The Verge.
So while it may get more difficult for a regular Joe to go haywire with a humanoid, this option doesn’t appear to be off the table for law enforcement agencies.

Mars is Mostly Dead. There's Still Magma Inside, so it's Slightly Alive
Since February 2019, NASA’s Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) lander has been making the first-ever measurements of tectonics on another planet. The key to this is InSight’s Seismic Experiment for Interior Structure (SEIS) instrument (developed by seismologists and geophysicists at ETH Zurich), which has been on the surface listening for signs of “marsquakes.” The dataset it has gathered (over 1,300 seismic events) has largely confirmed what planetary scientists have long suspected: that Mars is largely quiet.
However, a research team led by ETH Zurich recently analyzed a cluster of more than 20 recent marsquakes, which revealed something very interesting. Based on the location and spectral character of these events, they determined that most of Mars’ widely distributed surface faults are not seismically active. Nevertheless, most of the 20 seismic events observed originated in the vicinity of Cerberus Fossae, a region consisting of rifts (or graben). These results suggest that geological activity and volcanism still play an active role in shaping the Martian surface.

Based on the seismic data gathered by InSight, the team concluded that low-frequency quakes could indicate the modern-day presence of molten magma in the Martian mantle. Specifically, they found that the epicenters of these quakes were located mostly in the innermost part of Cerberus Fossae – at depths of 30 to 50 km (18.6 to 31 mi) beneath the surface. In this region, named after the hellhound that guards the gates of Hades (the underworld in Greek mythology), the terrain is sinking under its own weight, forming parallel rifts that pull the crust of Mars apart.
The team theorized that these quakes could be the last rumbles from this once-active volcanic region or that magma is moving eastward beneath the surface towards its next eruption. When the team examined orbital images of this area, they noticed that these quakes happened very close to a structure in the Cerberus Fossae Mantling Unit (previously designated a “young volcanic fissure”). This feature was surrounded by dark deposits of dust, which was present in all directions and not only in the dominant direction of the wind (as was expected).
As Stähler explained in a recent ETH Zurich press release, the only explanation for this was the presence of volcanic activity in the recent past. “The darker shade of the dust signifies geological evidence of more recent volcanic activity – perhaps within the past 50,000 years – relatively young, in geological terms,” he said.
Because of its terrestrial (rocky) nature and its proximity to Earth, Mars provides opportunities to study geological processes similar to those that shaped our planet. While technically closer, Venus’s super dense atmosphere prevents missions from studying it with anything other than surface-mapping radar and temperatures hot enough to melt lead. Because of their distance from Earth, which imposes communication delays, all other bodies in the Solar System have only been studied by orbiters and probes.

In addition, Mars is the only terrestrial planet beyond Earth known to have a core composed of iron, nickel, and sulfur that may have once supported a magnetic field. On Earth, this field results from dynamo action in the planet’s interior, where a liquid outer core rotates around a solid inner core (in the opposite direction as Earth’s rotation). It is widely believed today that roughly 4 billion years ago, the interior of the Red Planet cooled rapidly, causing the outer core to solidify while the inner core became molten. Without this field, Mars’ atmosphere was slowly stripped away by solar wind for eons.
Previously, scientists suspected this also meant that Mars became geologically dead billions of years ago. Nevertheless, these and other indications provided by robotic missions suggest that geological activity has not entirely ceased within the Red Planet. While considerable research still needs to be done to confirm these results, the evidence of potential magma in Mars’ mantle today is fascinating. These results demonstrate the effectiveness of the InSight lander and its sophisticated instruments and how multiple robotic missions working together can lead to breakthroughs. Said co-author Domenico Giardini:
“InSight’s SEIS is the most sensitive seismometer ever installed on another planet. It affords geophysicists and seismologists an opportunity to work with current data showing what is happening on Mars today – both at the surface and in its interior.”
In the coming years, many more robotic orbiters, landers, and rovers are bound for Mars. The research they conduct into Mars’ surface geology, environment, climate, and atmosphere will pave the way for crewed missions planned for the 2030s.
