Lawmaker states "U.S. is holding secrets on UFOs"
Lawmaker states "U.S. is holding secrets on UFOs"
Rep. Tim Burchett (R-Tenn.) says the American public is being "hosed" when it comes to the government releasing information about UFOs. Burchett believes the government is withholding serious information on UFOs from the public.
Rep. Tim Burchett's statement comes at the same time as NASA announces their Unidentified Aerial Phenomena study team members.
NASA has selected 16 individuals to participate in its independent study team on unidentified aerial phenomena (UAP). Observations of events in the sky that cannot be identified as aircraft or as known natural phenomena are categorized as UAPs.
The independent study will begin on Monday, Oct. 24. Over the course of nine months, the independent study team will lay the groundwork for future study on the nature of UAPs for NASA and other organizations. To do this, the team will identify how data gathered by civilian government entities, commercial data, and data from other sources can potentially be analyzed to shed light on UAPs. It will then recommend a roadmap for potential UAP data analysis by the agency going forward.
NASA has brought together some of the world's leading scientists, data and artificial intelligence practitioners, aerospace safety experts, all with a specific charge, which is to tell us how to apply the full focus of science and data to UAP.
Note:
And then NASA says the following in their announcement:
"Consistent with NASA’s principles of openness, transparency, and scientific integrity, this report will be shared publicly,” “All of NASA’s data is available to the public – we take that obligation seriously – and we make it easily accessible for anyone to see or study."
What a hypocrisy, besides don't expect too much from this study, NASA as well as the Government have already collected so much information and evidence on the existing of the UFO phenomenon, but both organizations have covered it up for already so many years and as Rep. Tim Burchett said "the government (and NASA too) is withholding serious information on UFOs from the public."

The Asteroid That Killed the Dinosaurs Also Flooded the World's Coastlines With a Catastrophic Tsunami
For decades, scientists have theorized that a massive impact caused the Cretaceous-Paleogene extinction event. This event occurred about 66 million years ago and caused the mass extinction of about 75% of all plant and animal species on Earth (including the non-avian dinosaurs). With the discovery of the massive Chicxulub crater in the Yucatan Peninsula (southern Mexico) in the 1970s, scientists concluded that they’d found the impact responsible. Based on all the available data, the Chicxulub Impact event is believed to have been as powerful as 100,000 billion metric tons (110,231 U.S tons) of TNT.
This blast was more powerful than all the nuclear devices in the world combined and sent an estimated 25 trillion metric tons (~27.5 US tons) of hot dust, ash, and steam into the atmosphere, creating a global winter. But according to new research led by the University of Michigan, an international team of geologists has determined that the impact also created a global tsunami. According to their findings, this tsunami was 30,000 times more powerful than the 2004 Indian Ocean tsunami, one of the largest and most devastating tsunamis on record.

To recap, evidence of the Chicxulub Impact is traced to the crater buried beneath the Yucatan Peninsula of southern Mexico. The crater measures 180 km (110 mi) in diameter and 20 km (12 mi) in depth and is centered offshore near the community of Chicxulub (from which it takes its name). Based on the crater’s dimensions, scientists estimate that the meteor that caused it measured about 14 km (8.7 mi) in diameter. Evidence of the impact is also found in the geological record in the form of deposits of iridium and other impact ejecta that were globally distributed.
This led to the scientific consensus that the impact that led to the Chicxulub crater was responsible for the Cretaceous-Paleogene extinction and possibly the volcanic activity that created the Deccan flood basalt in India. For the sake of their study, Range and her colleagues sought to determine the effects this impact had on the world’s oceans, from the initial moment of contact to the point where it became a global tsunami. To do this, the team created the first global simulation of this impact using hydrocode (which models fluid systems in 3D) and a shallow-water ocean model.
As study co-author Brian Arbic – a researcher with the University of Michigan (Ann Arbor), the IGE, and LEGO – told Universe Today via email, the simulation involved three steps. In the first step, the hydrocode was run by co-author Brandon Johnson (Purdue University) and simulated the first ten minutes of the impact. During this time, explained Arbic, the effects were nothing short of cataclysmic:
“[M]aterial from the asteroid, the underlying bedrock of the Earth, sediment, and ocean was displaced tens of kilometers above the atmosphere and (in the other direction) tens of kilometers below the Earth’s surface – in other words, a great big hole was dug out of the Earth. A massive crater was created by this impact, as well as an outward propagating “rim wave”. Most of the energy in the tsunami is due to the rim wave, but there is also a significant secondary effect due to water rushing back into the crater that the impact created.”

The second step was performed by Range as part of her Master’s Thesis at the University of Michigan, Ann Arbor. This consisted of putting the output of the hydrocode into two global shallow-water tsunami propagation models. These included the Modular Ocean Model 6 (MOM6), developed by co-author Alistair J. Adcroft (a research oceanographer from Princeton University), and the Method of Splitting Tsunami (MOST) developed by co-author Vasily Titov – a senior tsunami modeler at the NOAA’s Pacific Marine Environmental Lab.
“Vasily simulated the tsunami with MOST, and the results are fairly similar to those obtained with MOM6,” said Arbic. “Obtaining similar results from two different models gave us more confidence in our results. We will examine differences between shallow-water models and other models in future work.”The third step consisted of co-authorTed Moore– a Professor Emeritus at the University of Michigan, Ann Arbor – examining the geological record of the Cretaceous-Paleogene boundary for signs of sediment erosion. This revealed that more erosion occurred in the North Atlantic and South Pacific basins than in the South Atlantic and North Pacific. In short, the geological record shows that the seafloor in these regions was eroded and scoured more aggressively, with flow velocities of about 100 meters per second (360 km/h; 224 mph).
Moreover, the model showed that the wavefront propagation velocities, the speed at which waves formed on the surface, were about 200 meters per second (720 km/h; 447 mph). This is consistent with what the team’s model predicted and constitutes the best observational evidence of a global tsunami at the Cretaceous-Paleogene boundary. Their results also indicate that the Cretaceous-Paleogene tsunami was several orders of magnitude more powerful than any observed in recorded history. As Range described it, the effects of the impact were seen worldwide:
“It was a global impact. The tsunami was seen across the globe in 48 hours. Most coastal regions saw waves hit the coastline. Depending on where you look, wave heights could be from 1 meter to hundreds of meters tall. At ten minutes post-impact, the wave that had formed in the Gulf of Mexico was 1.5 km tall. This tsunami has 30,000 times the energy of the 2004 Indian Ocean Tsunami.”

This research provides additional insight into one of the most important events in geological history. In addition, said Range, the research has significant implications for planetary defense:
“The Chicxulub event had many important impacts, which have been previously documented – fires, wild swings of temperature (both very hot and very cold), destruction and eventual resetting of the predominant forms of life on Earth, and more. The tsunami was another important impact, and we plan to continue studying this tsunami and its impacts on the geological record that we can still examine. Impacts from large asteroids and meteors could happen again, which is why NASA recently ran the DART mission to see if they could be deflected.”
DINOSAURUSSEN KREGEN NA METEORIETINSLAG OOK NOG EEN MONSTERLIJKE TSUNAMI TE VERWERKEN
DINOSAURUSSEN KREGEN NA METEORIETINSLAG OOK NOG EEN MONSTERLIJKE TSUNAMI TE VERWERKEN

Op sommige plekken zouden zelfs meer dan een kilometer hoge golven zijn ontstaan.
Zo’n 66 miljoen jaar geleden sloeg een enorme ruimtesteen op aarde in. De inslag leidde tot het uitsterven van tal van planten- en diersoorten, waarvan de dinosaurussen veruit de bekendste slachtoffers zijn.
Tsunami De afgelopen jaren is er veel onderzoek gedaan naar de inslag en de gevolgen daarvan. Zo gaan onderzoekers er bijvoorbeeld van uit dat de inslag grote hoeveelheden stof in de atmosfeer bracht, waardoor zonlicht werd tegengehouden en de temperaturen wereldwijd sterk daalden. Maar behalve een jarenlange winter kregen de organismen die de inslag in eerste instantie overleefden nog meer voor de kiezen, zo wijst nieuw onderzoek uit. Zo zou de inslag ook een monstertsunami hebben voortgebracht die zelfs duizenden kilometers verderop grote schade aanrichtte.
Model en geologische data De onderzoekers trekken die conclusie – eerder deze maand gepubliceerd in het blad AGU Advances – onder meer op basis van modellen. Die modellen werden ingezet om het pad en de kracht van de tsunami te achterhalen. Vervolgens gebruikten de onderzoekers geologische gegevens, verzameld op meer dan 100 plaatsen wereldwijd die de tsunami volgens het model heeft aangedaan, om na te gaan of ze sporen van die tsunami konden vinden. En dat lukte, zo vertelt onderzoeker Molly Range. “De tsunami was sterk genoeg om de sedimenten in de oceaan te verstoren of eroderen.” Het resultaat is dat onderzoekers op plekken die de tsunami heeft bezocht door elkaar gehusselde sedimentlagen aantreffen of zelfs complete sedimentlagen missen. “De distributie van de erosie en hiaten in de mariene sedimenten daterend uit het einde van het Krijt, zijn in lijn met de resultaten van ons model,” aldus onderzoeker Molly Range.
Superkrachtige tsunami Het model en de geologische gegevens schetsen zo samen een vrij eenduidig en angstaanjagend beeld. “Onze simulaties laten zien dat de tsunami zo groot was dat metershoge golven het leeuwendeel van ‘s werelds kustlijnen bereikten,” vertelt Range aan Scientias.nl. “Het is dan ook bijna onmogelijk om deze tsunami te vergelijken met moderne tsunami’s.” Maar als we dat dan toch willen proberen, komt eigenlijk zelfs de krachtigste tsunami uit de recente geschiedenis niet eens in de buurt; in vergelijking met de tsunami die in 2004 in de Indische Oceaan ontstond en honderdduizenden levens eiste, was de tsunami die zo’n 66 miljoen jaar geleden ontstond nog eens 30.000 keer krachtiger.
Golven Zo’n 2,5 minuut nadat de ruimtesteen insloeg zou ejecta – door de inslag weggeslingerd materiaal – als een soort gordijn rond de plaats van inslag hebben gehangen en een muur van water bij de inslag vandaan hebben geduwd. Die muur van water zou heel kort tot wel 4,5 kilometer hoog zijn geweest, maar zijn ingestort toen ook het ejecta weer naar beneden stortte. Het ejecta stortte daarbij deels in het water, waardoor weer nieuwe, zeer chaotische golven ontstonden. “Na tien minuten was al het ejecta gevallen en bleef er op zo’n 220 kilometer van de plaats van inslag een 1,5 kilometer hoge, ringvormige golf over die zich door dieper water bleef verspreiden,” zo schrijven de onderzoekers.
Ongeveer een uur na de inslag had deze golf zich tot buiten de hedendaagse Golf van Mexico verspreid en het noordelijke deel van de Atlantische Oceaan al bereikt. En zo’n vier uur later was ook de Stille Oceaan door de tsunami beroerd. 24 uur na de inslag hadden de golven de Atlantische en Stille Oceaan al doorkruist en – dus van twee zijden – de Indische Oceaan bereikt. Zo’n 48 uur na de inslag hadden flinke golven bijna alle kustlijnen wereldwijd aangedaan.
Overstromingen In de Golf van Mexico zouden de golven in open water een hoogte van meer dan 100 meter hebben bereikt. Op het moment dat de golven de kustlijnen langs het noordelijke deel van de Atlantische Oceaan en het zuidelijke deel van de Stille Oceaan naderden, zouden de golven al flink lager zijn geworden, maar nog wel altijd meer dan 10 meter hoog zijn geweest. Maar doordat de nog altijd hoge golven bij het naderen van de kust door ondieper water bewogen, zouden ze kort voor ze aan land gingen juist weer aanzienlijk hoger zijn geworden. “De meeste kustgebieden zouden in zekere mate overstroomd en geërodeerd zijn,” stellen de onderzoekers.
Regionale verschillen Hoewel dus sprake was van een wereldwijde tsunami, was de impact die deze op de kustgebieden had overigens niet overal even groot. Zo moeten de kustlijnen langs het noordelijke deel van de Atlantische Oceaan bijvoorbeeld veel meer te verduren hebben gehad dan de kustlijnen langs het zuidelijke deel van de Atlantische Oceaan en de Middellandse Zee. “Dat deze (laatstgenoemde, red.) gebieden enigszins gespaard werden, heeft alles te maken met de ligging van het land,” legt Range aan Scientias.nl uit. “Landen of continenten vormen een blokkade wanneer de golf door de oceaan reist. Zo zie je bijvoorbeeld dat wanneer de tsunami van de Golf van Mexico vandaan reist, er landbarrières zijn tussen de plaats van inslag en het Mediterrane gebied.”
Vervolgonderzoek Hoewel onderzoekers in grove lijnen dus wel een beeld hebben van de impact die de tsunami op kustlijnen heeft gehad, is meer onderzoek hard nodig. Zo willen de wetenschappers bijvoorbeeld gaan uitzoeken in hoeverre de tsunami op verschillende plaatsen tot overstromingen leidde. “We zijn daarbij met name geïnteresseerd in hoe ver de tsunami de Western Interior Seaway (een voormalige zeestraat die het huidige Noord-Amerika in tweeën splitste, red.) in wist te reizen.”
Het onderzoek moet uiteindelijk meer inzicht geven in de wijze waarop die enorme inslag 66 miljoen jaar geleden van invloed was op onze planeet en alles wat daarop leefde. “De inslag had veel belangrijke gevolgen die eerder al zijn gedocumenteerd,” vertelt Range. “Grote branden, enorme fluctuaties in temperatuur (zowel heel warm als heel koud), vernietiging en herschikking van overheersende levensvormen op aarde, enzovoort.En de tsunami was een ander, heel belangrijk gevolg.”
Neanderthalers leefden samen in kleine groepen, waar incest niet vreemd was: onderzoek naar eerste familie oermensen licht tipje van de sluier
Wetenschappers, waaronder de Nobelprijswinnaar van dit jaar Svante Pääbo, hebben de resten van een groep Neanderthalers aan een genetische analyse onderworpen. Een primeur, want voor het eerst gunt een onderzoek ons een blik achter de schermen bij een familie neanderthalers. Wat blijkt? Ze leefden voornamelijk in kleine groepen en waren niet vies van incest. Dat schrijven de onderzoekers van het Max Planck Instituut voor Evolutionaire Antropologie in het vakblad Nature.
In Siberië, in het Altaj-gebergte, zijn de restanten van maar liefst 13 verschillende neanderthalers - onder wie mannen, vrouwen en ook kinderen - teruggevonden. Het bleek om een groep neanderthalers te gaan die er zo’n 54.000 jaar geleden samenleefden: een vader, zijn dochter, nog een andere man en wellicht nog een tante en neefje van de vader en dochter. De bonte familieverzamelingen betekenden een buitenkansje want nooit eerder werd er onderzoek gedaan naar groepen neanderthalers die daadwerkelijk hebben samengeleefd.
“Resten van neanderthalers die goed bewaard zijn gebleven, zijn tamelijk zeldzaam", aldus hoofdonderzoeker Benjamin Peter. “Vaak vinden we slechts enkele individuen terug waarvan de ene duizenden jaren ouder of jonger is dan de andere."
Gedrag van gorilla’s
Met behulp van een genetische analyse slaagden wetenschappers erin om de sociale structuren van de groep bloot te leggen. En dat leverde op zijn minst interessante resultaten op. Zo was er in sterke mate sprake van inteelt. Niet zo verbazingwekkend, volgens de onderzoekers. De verschillende gemeenschappen leefden ver van elkaar verwijderd en telden slechts tien tot dertig individuen. Enkel de vrouwen verplaatsten zich soms van de ene groep naar de andere, al dan niet vrijwillig. Kortom, ze leefden net zoals groepen gorilla’s dat momenteel doen.
“De samenleving die wij bestudeerden was waarschijnlijk zeer klein”, aldus hoofdonderzoeker Benjamin Peter. “Toch slaagden ze erin honderden tot zelfs duizenden jaren te overleven in de ruige omgeving. Dat verdient respect.” De bestudeerde neanderthalers joegen onder meer op alpensteenbokken, bizons en paarden. Behalve de restanten van de neanderthalers en dieren, werden er ook tal van stenen werktuigen teruggevonden.
Nobelprijswinnaar Svante Pääbo
De Zweedse wetenschapper Svante Pääbo (67) ontving de Nobelprijs voor Geneeskunde voor zijn revolutionair onderzoek naar de menselijke evolutie en naar het genetisch materiaal van uitgestorven mensachtigen waaronder ook de neanderthaler (zie ook video hieronder).

Astronomers Chart the Influence of Dark Matter and Dark Energy on the Universe by Measuring Over 1,500 Supernovae
Astronomers Chart the Influence of Dark Matter and Dark Energy on the Universe by Measuring Over 1,500 Supernovae
In 2011, the Nobel Prize in physics was awarded to Perlmutter, Schmidt, and Reiss for their discovery that the universe is not just expanding, it is accelerating. The work supported the idea of a universe filled with dark energy and dark matter, and it was based on observations of distant supernovae. Particularly, Type Ia supernovae, which have consistent light curves we can use as standard candles to measure cosmic distances. Now a new study of more than 1,500 supernovae confirms dark energy and dark matter, but also raises questions about our cosmological models.
The study is based on datasets known as Pantheon+ and SH0ES. It contains 1,701 light curve measurements of 1,550 Type Ia supernovae spanning two decades of observations and a cosmic period of 10 billion years. It is the most comprehensive survey of dark energy supernova measurements ever made. The data set covers the transition from the early universe, which was dominated by dark matter, to the modern universe dominated by dark energy. Thus, it confirms the effects of both of these. The data set is so detailed that it also gives us a measure of the Hubble parameter to an accuracy of five sigmas, which rules out systematic errors in our measurements. Based on this data, we know we live in a universe that is about two-thirds dark energy and one-third matter and dark matter.
But here’s where things get strange. Over the years we have measured the effects of dark energy and dark matter in numerous ways. In addition to supernova observations, we also see the effects of fluctuations in the cosmic background, the clustering of galaxies over time, gravitational waves, and even microwave laser light. They all tell a similar story of a universe dominated by dark matter and dark energy. But they don’t tell exactly the same story. This is most clearly seen in the discrepancies in Hubble parameter values.
The Hubble parameter, or Hubble constant, is a measure of the rate at which the universe is expanding. Since 2001, we’ve known the Hubble parameter is about 64 to 80 (km/s)/Mpc, giving an age for the universe of somewhere between 12.5 and 15.6 billion years. Back then our uncertainty of the exact value was pretty large. Since then our measurements have gotten more precise, and the value has narrowed down to about 70 (km/s)/Mpc, or 14 billion years. The problem is that supernovae measurements give a value larger than 70, while cosmic background measurements give a value a bit lower than 70. This disagreement is known as the Hubble tension, and it was hoped that better observations would resolve the issue. This latest study confirms it is both real and not going away.

The team used the Pantheon+ data to look at two different results. The supernova measure, Pantheon+ SH0ES, gives a Hubble parameter of 72 – 74 (km/s)/Mpc. The cosmic background measure, Pantheon+ Planck, gives a Hubble parameter of 66 – 68 (km/s)/Mpc. Both are very precise, and they contradict each other. The study confirms that the Hubble tension is real. It isn’t due to any error of measurement, and we can’t say that one or the other is wrong.
This study has basically thrown down the figurative glove at the feet of theorists. Given our big bang, dark energy, and dark matter universe model is confirmed, how do you resolve this disagreement in observations? The short answer is that we don’t know, but it will be an exciting mystery to figure out.

EXOPLANEET MET DE DICHTHEID VAN EEN MARSHMALLOW ONTDEKT ROND RODE DWERGSTER
EXOPLANEET MET DE DICHTHEID VAN EEN MARSHMALLOW ONTDEKT ROND RODE DWERGSTER
Vivian Lammerse
Het is de ‘luchtigste’ planeet die tot op heden rond dit type ster is aangetroffen.
Astronomen hebben in een baan rond een koele, rode dwergster een ongewone planeet aangetroffen. Het gaat om een Jupiter-achtige exoplaneet met een extreem lage dichtheid, vergelijkbaar met die van… een marshmallow.
TOI-3757 b Onderzoekers kwamen de opmerkelijke gasreus op het spoor met behulp van planetenjager TESS, zo valt er te lezen in The Astrophysical Journal. Vervolgens werd deze nader bestudeerd met de WIYN 3,5-meter telescoop; de op één na grootste optische telescoop van het Kitt Peak National Observatory in Arizona. De planeet is TOI-3757 b genoemd en cirkelt rond een koele, rode dwergster. De gasreus bevindt zich op ongeveer 580 lichtjaar afstand van de aarde, in het sterrenbeeld Voerman.
Grootte en omloopbaan Dankzij gegevens van planetenjager TESS, slaagden de onderzoekers erin de diameter van de planeet te berekenen. TOI-3757 b blijkt een diameter te hebben van 150.000 kilometer. Hiermee is hij net iets groter dan planeet Jupiter uit ons eigen zonnestelsel. Daarnaast voltooit de nieuw ontdekte gasreus in slechts 3,5 dagen een volledige baan rond zijn moederster. En dat is krap. Ter vergelijking, Mercurius, de dichtstbijzijnde planeet in ons eigen zonnestelsel, doet er 88 dagen over om een rondje rond de zon te voltooien.
Massa en dichtheid Met behulp van geavanceerde metingen wisten astronomen vervolgens de massa van de planeet te achterhalen. En daaruit bijkt dat TOI-3757 b een massa heeft van ongeveer een kwart van die van Jupiter – of ongeveer 85 keer die van de aarde. Met gegevens over de grootte en de massa van de planeet bij de hand, kon het team de gemiddelde dichtheid bepalen. En die komt neer op 0,27 gram per kubieke centimeter. Dit is minder dan de helft van de dichtheid van Saturnus (de planeet in ons zonnestelsel met de laagste dichtheid), ongeveer een kwart van de dichtheid van water (wat betekent dat de planeet zou drijven als het in een gigantische badkuip gevuld met water zou worden geplaatst) en is vergelijkbaar met de dichtheid van een marshmallow.

De extreem lage dichtheid van TOI-3757 b zet astronomen voor een raadsel. Nog niet eerder is er namelijk zo’n ‘luchtige’ planeet rond een rode dwergster ontdekt. Bovendien zijn er ook nog maar weinig nabije reuzenplaneten rond dit type ster gevonden. Rode dwergsterren zijn vrij kleine en lichtzwakke sterren. Hoewel ze ‘koel’ zijn in vergelijking met sterren zoals onze zon, kunnen rode dwergen extreem actief zijn en op krachtige wijze uitbarsten, waardoor een mogelijk rondom cirkelende planeet van zijn atmosfeer wordt ontdaan. Het betekent dat dergelijke zonnestelsels onherbergzame plekken lijken voor de vorming van een planeet zoals TOI-3757 b.
Meer over rode dwergsterren Rode dwergsterren (M-sterren) zijn de meest voorkomende en langstlevende sterren in het heelal. Ze zijn een stukje kleiner en koeler dan onze eigen zon. Rode dwergen blijken vaak rotsachtige planeten te herbergen. En sommige van deze aardachtige werelden draaien ook nog eens in de leefbare zone. Al deze ingrediënten samen maken rode dwergen erg interessant in de zoektocht naar buitenaards leven. Toch komen stronomen daar steeds vaker op terug. Planeten die rond rode dwergen cirkelen worden vaak gebombardeerd met gevaarlijke röntgen- en ultraviolette (UV) straling, die tot honderdduizenden keren intenser kan zijn dan wat de aarde van de zon ontvangt. Omcirkelende exoplaneten zijn daardoor hun leven niet zeker en kunnen ieder moment van hun atmosfeer worden beroofd. Het betekent dat deze planeten mogelijk kurkdroog zijn. Al met al niet de perfecte omstandigheden voor het ontstaan van leven. Over de kansen om leven te vinden rond rode dwergen zijn onderzoekers dan ook niet meer zo optimistisch.
Hoe een forse gasreus met zo’n lage dichtheid rond een rode dwerg kan zijn ontstaan? De onderzoekers stellen twee mogelijke theorieën voor.
Theorieën De extreme lage dichtheid kan het resultaat zijn van twee factoren. De eerste heeft betrekking op de rotsachtige kern van de planeet. Men denkt dat gasreuzen in eerste instantie bestaan uit een massieve, rotsachtige kern van ongeveer tien keer de massa van de aarde. Vervolgens trekken ze grote hoeveelheden aangrenzend gas naar zich toe. En zo ontstaan de gasreuzen die we vandaag de dag kennen. Daarnaast beschikt de ster waar TOI-3757b omheen cirkelt over minder zware elementen in vergelijking met andere rode dwergsterren die gasreuzen herbergen. Dit kan ertoe hebben geleid dat de rotsachtige kern langzamer werd gevormd. De gasaanwas kwam daardoor trager op gang, wat vervolgens de algehele dichtheid van de planeet beïnvloedde.
De tweede theorie heeft betrekking op de omloopbaan van TOI-3757b. Vooralsnog beschouwen astronomen de baan van de gasreus als enigszins elliptisch – soms nadert hij zijn moederster dichter dan op andere momenten. Dit resulteert in een aanzienlijke, kortstondige en overmatige opwarming waardoor de atmosfeer van de planeet opzwelt.
James Webb Welke theorie juist is, zal uit vervolgonderzoek moeten blijken. “Met toekomstige waarnemingen met behulp van NASA’s nieuwe James Webb-ruimtetelescoop, zouden we kunnen achterhalen of de atmosfeer van de planeet inderdaad opgezwollen is,” aldus onderzoeker Jessica Libby-Roberts.
De zoektocht naar soortgelijke systemen met gigantische planeten – waarvan ooit werd gedacht dat ze extreem zeldzaam zijn rond rode dwergen – gaat door. Astronomen hopen zo beter te gaan begrijpen hoe dergelijke planeten het levenslicht zien. Ook speurt TESS verder naar andere exoplaneten. Dit kunnen dan weer interessante doelen zijn voor de krachtige James Webb-telescoop, die in staat is de atmosferen te karakteriseren. En misschien dat we op deze manier ooit wel op een potentieel rotsachtige wereld stuiten die leven herbergt…

Rectangle UFO Over Saint Paul, Minnesota Oct 20, 2022, Video, UFO Sighting News.
Date of sighting: Oct 20, 2022 Location of sighting: Saint Paul, Minnesota, USA Source: MUFON
Man oh man! This sighting reminds me of the Sephenville, Texas UFO where back in 2009 a whole city including its mayor and chief of police saw a 300 meter metal rectangle UFO move over the city and toward the US president Bush ranch...before it disappeared for airport radar.
This UFO is awesome and erie, with its greenish light surrounding the UFO hovering over the city. Easily this UFO is also about 300 meters across. Coincidence? I think not. Some comments below my video are saying its probably lights from below because of Halloween. Perhaps, but when similar size, shape UFOs were seen in plain daylight, its harder to dismiss this event. We need more video of this event, its the only sure way to tell for sure.

Object just hovered no sound at all. Keeps coming back.
Some kind of a cube-shaped formation with strange light around it was filmed in the night sky above Saint Paul in Minnesota. This was filmed back in May 2022 but it was just recently published online.
Searching for extraterrestrial life will not change a scientist’s reputation, but if he/she believes that aliens exist, that might be problematic. Legendary astrophysicist Carl Sagan never denied the existence of life beyond Earth, however, John E. Mack, a Harvard professor had to face the wrath of the scientific community for his thoughts on aliens. Interestingly, Dr. Mack was a highly regarded intellectual.
John Edward Mack was born in 1929. He pursued his medical degree at Harvard where he would later practice and teach as a psychiatrist. He established the psychiatry department at the university’s Cambridge Hospital and oversaw the division for almost ten years. Mack investigated dreams and the psychological effects of the Cold War early in his career. In addition, he was awarded the Pulitzer Prize for his famous biography of T.E. Lawrence, A Prince of Our Disorder.
Early in the 1990s, Dr. Mack revealed something shocking. He checked patients who said they had been abducted by extraterrestrials and believed them. He wrote a book titled “Abduction: Human Encounters with Aliens” in 1994 that had a case study of 13 people. In 1999, “Passport to the Cosmos,” the sequel, was released. He claimed that Abduction was a logical development from his earlier work, which included studies of T E Lawrence, suicide, and the threat of nuclear warfare: “the connection resides in the matter of identity—who we are in the deepest and broadest sense.”
Despite the skepticism of his contemporaries, Dr. Mack persisted in his quest to integrate UFOs and aliens into the realm of modern science. But to be fair, he himself was initially dubious (like any good scientist would be). He acknowledged having grown up in a materialist home, but once he started interviewing “experiencers,” he discovered that his formative philosophy had been completely turned around.

“When I heard about this phenomenon in 1990, I was very doubtful. I thought it must be some kind of mental illness,” he told The Washington Post during an interview conducted in the mid-’90s. “I came gradually to the conclusion that I could not find any psychiatric explanation or other explanation except that some kind of trauma happened to them.”
What happened to Dr. Mack that made him believe and promote such outlandish claims? “These people suffered from no obvious psychiatric disorder, except the effects of traumatic experience, and were reporting with powerful emotion what to them were utterly real experiences,” he wrote in Abduction (via Vanity Fair).
“Furthermore, these experiences were sometimes associated with UFO sightings by friends, family members, or others in the community, including media reporters and journalists, and frequently left physical traces on the individuals’ bodies, such as cuts and small ulcers that would tend to heal rapidly and followed no apparent psychodynamically identifiable pattern as do, for example, religious stigmata. In short, I was dealing with a phenomenon that I felt could not be explained psychiatrically, yet was simply not possible within the framework of the Western scientific worldview.”
On January 10, 1990, Dr. Mack met Budd Hopkins, which became a life-changing event for him. Hopkins claimed to have seen a UFO on Cape Cod in 1964, and he then investigated into a neighbor’s story of seeing a spaceship with nine or ten tiny aliens land in a park close to Fort Lee, New Jersey.
Hopkins covered this story in a piece for “The Village Voice” that Cosmopolitan later published. His 1981 book “Missing Time” and its 1987 sequel “Intruders: The Incredible Visitations at Copley Woods” cemented his reputation as the father of the alien-abduction movement. He was immediately swarmed by abductees, whom he investigated under hypnosis.
Hopkins was then starting his investigation into the alleged abduction of the woman he dubbed Linda Cortile under the Brooklyn Bridge by UFOs, which would later become the subject of his third book, Witnessed, published in 1996. He gave Dr. Mack a box of letters from people reacting to aliens. “I think most of these people are perfectly sane, with real experiences,” Hopkins recalled telling Mack. But, he added, Mack could decide for himself. He was the doctor.
Mack was working with experiencers two years after first meeting Hopkins when he told his shocked fellow psychiatrists at Cambridge Hospital about extraterrestrial abduction. In 1992, he and David E. Pritchard, a trailblazing researcher in the field of atom optics at M.I.T., persuaded that university to host a ground-breaking conference on extraterrestrial abductions. “If what these abductees are saying is happening to them isn’t happening,” Mack demanded, “what is?”
Once NOVA, a popular primetime science series on American television interviewed Dr. Mack asking him if people are really being snatched from their beds by aliens and experiments onboard a spaceship. (Source)
Dr. Mack replied:
Just how literally to take this, is one of the most interesting and complex aspects of this. And I want to walk through that as clearly as I can. There are aspects of this which I believe we are justified in taking quite literally. That is, UFOs are in fact observed, filmed on camera at the same time that people are having their abduction experiences.
People, in fact, have been observed to be missing at the time that they are reporting their abduction experiences. They return from their experiences with cuts, ulcers on their bodies, triangular lesions, which follow the distribution of the experiences that they recover, of what was done to them in the craft by the surgical-like activity of these beings.
All of that has a literal physical aspect and is experienced and reported with appropriate feeling, by the abductees, with or without hypnosis or a relaxation exercise.
…There is a—I believe, a gradation of experiences and that go from the most literal physical kinds of hurts, wounds, person removed, spacecraft that can be photographed, to experiences which are more psychological, spiritual, involve the extension of consciousness. The difficulty for our society and for our mentality is, we have a kind of either/or mentality. It’s either, literally physical; or it’s in the spiritual other realm, the unseen realm. What we seem to have no place for—or we have lost the place for—are phenomena that can begin in the unseen realm, and cross over and manifest and show up in our literal physical world.
So the simple answer would be: Yes, it’s both. It’s both literally, physically happening to a degree; and it’s also some kind of psychological, spiritual experience occurring and originating perhaps in another dimension. And so the phenomenon stretches us, or it asks us to stretch to open to realities that are not simply the literal physical world, but to extend to the possibility that there are other unseen realities from which our consciousness, our, if you will, learning processes over the past several hundred years have closed us off.
Mack hypothesized that the entities might have just come from a parallel universe rather than from space. When he finally published “Abduction,” he claimed that his experiences had “amply corroborated” Hopkins and Jacobs’ research, “particularly that the abduction phenomena is in some central way implicated in a breeding program that leads to the development of alien/human hybrid progeny.” Almost all of his abductees returned with “a resolve to changing their relationship to the earth,” which led him to the further conclusion that the aliens were bearing warnings about threats to the planet
In November 1994, Dr. Mack performed his analysis on Ariel School students who claimed to encountered alien beings, which lasted for 48 hours. And, based on the results of the interviews, he came to the conclusion that the students had really experienced the event and perceived it exactly as they described it.
“It looked like it was glinting in the trees. It looked like a disc. Like a round disc,” one child witness told the BBC a few days after the incident. “I saw something silver on the ground amongst the trees. And a person in black,” another child said.
The same year, Harvard started a review of Mack’s position, but he resisted and kept his tenure. But the harm to his professional reputation was significant. Arnold Relman, Emeritus Professor at Harvard Medical School, told the Los Angeles Times in 2001 that “he’s not taken seriously by his colleagues anymore.”
Dr. Mack also received harsh criticism from those outside the academic world. He was duped by a journalist Donna Bassett into thinking that she had been abducted by aliens too. She claimed that she had been on a UFO in outer space during the Cuban Missile Crisis and witnessed Kennedy and Kruschev conversing. Dr. Mack accepted her fanciful story. She admitted to being a fraud in public, but the professor’s views on aliens visiting earth did not change. It damaged the respected university’s reputation in terms of public relations. (Source)
As a result, Dr. Mack was the subject of an internal Harvard probe. The executive branch wanted his dismissal. Professor of law Alan Dershowitz was among the academics who questioned the validity of the probe because Dr. Mack had not broken any of the Harvard school’s behavior policies.
The investigation was finished more than a year later, and the doctor kept his tenured position. But his formerly impeccable reputation was tarnished. His coworkers ceased to regard him seriously. Up until his tragic death, hit by a drunk driver while crossing the street in London in 2004, Professor Mack, a UFO and extraterrestrial abduction believer oversaw the department of psychiatry at Harvard University.

SCIENTISTS SUGGEST OUR BRAINS WORK LIKE QUANTUM COMPUTERS
SCIENTISTS SUGGEST OUR BRAINS WORK LIKE QUANTUM COMPUTERS
"AS A RESULT, WE CAN DEDUCE THAT THOSE BRAIN FUNCTIONS MUST BE QUANTUM."
GETTY IMAGES/FUTURISM
Brain Power
As physicists endeavor to build bigger and better quantum computers, a powerful one may have already been lurking inside our heads all along.
In a new study published this month in the Journal of Physics Communications, a team of scientists from Trinity College Dublin suggest that our brains could actually be using quantum computation.
If confirmed — something that will require extensive investigation — the finding could help explain why, in certain respects, our brains still outdo supercomputers.
Quantum Cerebrum
Their conclusion relies on the idea of quantum entanglement, a phenomenon describing particles changing each other's quantum state, even when they are separated by a large distance.
"We adapted an idea, developed for experiments to prove the existence of quantum gravity, whereby you take known quantum systems, which interact with an unknown system," said Christian Kerskens, study co-author and lead physicist at the Trinity College Institute of Neuroscience, in a statement.
"If the known systems entangle, then the unknown must be a quantum system, too," he explained. "It circumvents the difficulties to find measuring devices for something we know nothing about."
In the case of this experiment, the proton spins of the water in our brains served as the "known system." Kerskens and his team then used a special form of MRI imaging to detect if any of the proton spins were quantum entangled.
Curiously, the scientists ended up detecting a specific kind of electrical brain signal known as heartbeat evoked potentials, which they say is normally not detectable with MRIs.
What allowed them to detect those potentials, the scientists suggest, is quantum entanglement in proton spins in the brain.
"If entanglement is the only possible explanation here then that would mean that brain processes must have interacted with the nuclear spins, mediating the entanglement between the nuclear spins," Kerskens concluded. "As a result, we can deduce that those brain functions must be quantum."
Entangled Thoughts
All in all, it's an intriguing suggestion, but there's a lot more that needs to be proven. For one, the study rides on relatively recent proposals in the field of quantum gravity.
And, as the scientists in the study admit, their efforts were largely undertaken through the perspective of quantum physics.
In short, to prove their theory, it'd require a substantial multidisciplinary effort, especially considering the complexity of the human brain — but it's a tantalizing possibility, nonetheless.
For one, falling into a black hole is easily the worst way to die.
(Image credit: Brian Christensen/Stocktrek Images)
Halloween is a time to be haunted by ghosts, goblins and ghouls, but nothing in the universe is scarier than a black hole.
Black holes – regions in space where gravity is so strong that nothing can escape – are a hot topic in the news these days. Half of the 2020 Nobel Prize in Physics(opens in new tab) was awarded to Roger Penrose for his mathematical work showing that black holes are an inescapable consequence of Einstein’s theory of gravity. Andrea Ghez and Reinhard Genzel shared the other half for showing that a massive black hole sits at the center of our galaxy(opens in new tab).
Black holes are scary for three reasons. If you fell into a black hole left over when a star died, you would be shredded. Also, the massive black holes seen at the center of all galaxies have insatiable appetites. And black holes are places where the laws of physics are obliterated.
I’ve been studying black holes for over 30 years. In particular, I've focused on the supermassive black holes that lurk at the center of galaxies. Most of the time they are inactive, but when they are active and eat stars and gas, the region close to the black hole can outshine the entire galaxy that hosts them. Galaxies where the black holes are active are called quasars. With all we’ve learned about black holes over the past few decades, there are still many mysteries to solve.
Death by black hole
Black holes are expected to form when a massive star dies. After the star's nuclear fuel is exhausted, its core collapses to the densest state of matter imaginable, a hundred times denser than an atomic nucleus. That’s so dense that protons, neutrons and electrons are no longer discrete particles. Since black holes are dark, they are found when they orbit a normal star. The properties of the normal star allow astronomers to infer the properties of its dark companion, a black hole.
The first black hole to be confirmed was Cygnus X-1, the brightest X-ray source in the Cygnus constellation. Since then, about 50 black holes have been discovered in systems where a normal star orbits a black hole. They are the nearest examples of about 10 million that are expected to be scattered through the Milky Way.
Black holes are tombs of matter; nothing can escape them, not even light. The fate of anyone falling into a black hole would be a painful "spaghettification," an idea popularized by Stephen Hawking in his book "A Brief History of Time." In spaghettification, the intense gravity of the black hole would pull you apart, separating your bones, muscles, sinews and even molecules. As the poet Dante described the words over the gates of hell in his poem Divine Comedy: Abandon hope, all ye who enter here.
Nature knows how to make black holes over a staggering range of masses, from star corpses a few times the mass of the Sun to monsters tens of billions of times more massive. That’s like the difference between an apple and the Great Pyramid of Giza.
The fate of anyone falling into a black hole would be a painful "spaghettification," an idea popularized by Stephen Hawking in his book "A Brief History of Time."
Just last year, astronomers published the first-ever picture of a black hole(opens in new tab) and its event horizon, a 7-billion-solar-mass beast at the center of the M87 elliptical galaxy.
It’s over a thousand times bigger than the black hole in our galaxy, whose discoverers snagged this year's Nobel Prize. These black holes are dark most of the time, but when their gravity pulls in nearby stars and gas, they flare into intense activity and pump out a huge amount of radiation. Massive black holes are dangerous in two ways. If you get too close, the enormous gravity will suck you in. And if they are in their active quasar phase, you’ll be blasted by high-energy radiation.
How bright is a quasar? Imagine hovering over a large city like Los Angeles at night. The roughly 100 million lights from cars, houses and streets in the city correspond to the stars in a galaxy. In this analogy, the black hole in its active state is like a light source 1 inch in diameter in downtown LA that outshines the city by a factor of hundreds or thousands. Quasars are the brightest objects in the universe.
The biggest black hole discovered so far weighs in at 40 billion times the mass of the Sun, or 20 times the size of the solar system. Whereas the outer planets in our solar system orbit once in 250 years, this much more massive object spins once every three months. Its outer edge moves at half the speed of light. Like all black holes, the huge ones are shielded from view by an event horizon. At their centers is a singularity, a point in space where the density is infinite.(opens in new tab) We can’t understand the interior of a black hole because the laws of physics break down. Time freezes at the event horizon and gravity becomes infinite at the singularity.
The good news about massive black holes is that you could survive falling into one. Although their gravity is stronger, the stretching force is weaker than it would be with a small black hole and it would not kill you. The bad news is that the event horizon marks the edge of the abyss. Nothing can escape from inside the event horizon, so you could not escape or report on your experience.
According to Stephen Hawking, black holes are slowly evaporating. In the far future of the universe, long after all stars have died and galaxies have been wrenched from view by the accelerating cosmic expansion, black holes will be the last surviving objects.
The most massive black holes will take an unimaginable number of years to evaporate, estimated at 10 to the 100th power, or 10 with 100 zeroes after it. The scariest objects in the universe are almost eternal.

James Webb-telescoop legt prachtige beelden vast van de "Zuilen van de Schepping”
Voor ruimtefanaten is het een bekend beeld: “De Zuilen van de Schepping”. Het is een van de mooiste bezienswaardigheden in de kosmos en nu heeft de nieuwe superruimtetelescoop James Webb hem opnieuw bezocht.
Wat je ziet op de beelden zijn dichte wolken van waterstofgas en stof in het sterrenbeeld Serpens, op zo’n 6.500 lichtjaar van de aarde. De Hubble-telescoop fotografeerde deze ruimtepracht al in 1995 en 2014.
James Webb kan met zijn infrarood detectoren veel van de lichtverstrooiende effecten van het stof van de pilaren negeren om de activiteit van de pasgeboren sterren te onderzoeken. “Ik bestudeer de Adelaarsnevel al sinds het midden van de jaren negentig. Ik wist dat gewoon dat de beelden van James Webb verbluffend zouden zijn. En dat zijn ze ook”, vertelde professor Mark McCaughrean, senior adviseur voor wetenschap bij het Europees Ruimteagentschap, aan BBC News.
De pilaren worden verlicht en gebeeldhouwd door het intense ultraviolette licht van massieve nabije sterren. Als je jezelf vandaag op magische wijze naar deze locatie zou kunnen verplaatsen, zouden de pilaren er hoogstwaarschijnlijk niet meer staan. We zien ze alleen omdat we naar ze kijken in het verleden. Het licht dat Webb ziet, heeft er 6.500 jaar over gedaan om de spiegels te bereiken.

NASA’s Webb Takes Star-Filled Portrait of Pillars of Creation
NASA’s Webb Takes Star-Filled Portrait of Pillars of Creation
The Pillars of Creation are set off in a kaleidoscope of color in NASA’s James Webb Space Telescope’s near-infrared-light view. The pillars look like arches and spires rising out of a desert landscape, but are filled with semi-transparent gas and dust, and ever changing. This is a region where young stars are forming – or have barely burst from their dusty cocoons as they continue to form.

NASA’s James Webb Space Telescope has captured a lush, highly detailed landscape – the iconic Pillars of Creation – where new stars are forming within dense clouds of gas and dust. The three-dimensional pillars look like majestic rock formations, but are far more permeable. These columns are made up of cool interstellar gas and dust that appear – at times – semi-transparent in near-infrared light.
Webb’s new view of the Pillars of Creation, which were first made famous when imaged by NASA’s Hubble Space Telescope in 1995, will help researchers revamp their models of star formation by identifying far more precise counts of newly formed stars, along with the quantities of gas and dust in the region. Over time, they will begin to build a clearer understanding of how stars form and burst out of these dusty clouds over millions of years.
NASA's Hubble Space Telescope made the Pillars of Creation famous with its first image in 1995, but revisited the scene in 2014 to reveal a sharper, wider view in visible light, shown above at left. A new, near-infrared-light view from NASA’s James Webb Space Telescope, at right, helps us peer through more of the dust in this star-forming region. The thick, dusty brown pillars are no longer as opaque and many more red stars that are still forming come into view.

Newly formed stars are the scene-stealers in this image from Webb’s Near-Infrared Camera (NIRCam). These are the bright red orbs that typically have diffraction spikes and lie outside one of the dusty pillars. When knots with sufficient mass form within the pillars of gas and dust, they begin to collapse under their own gravity, slowly heat up, and eventually form new stars.
What about those wavy lines that look like lava at the edges of some pillars? These are ejections from stars that are still forming within the gas and dust. Young stars periodically shoot out supersonic jets that collide with clouds of material, like these thick pillars. This sometimes also results in bow shocks, which can form wavy patterns like a boat does as it moves through water. The crimson glow comes from the energetic hydrogen molecules that result from jets and shocks. This is evident in the second and third pillars from the top – the NIRCam image is practically pulsing with their activity. These young stars are estimated to be only a few hundred thousand years old.
Although it may appear that near-infrared light has allowed Webb to “pierce through” the clouds to reveal great cosmic distances beyond the pillars, there are no galaxies in this view. Instead, a mix of translucent gas and dust known as the interstellar medium in the densest part of our Milky Way galaxy’s disk blocks our view of the deeper universe.
This scene was first imaged by Hubble in 1995 and revisited in 2014, but many other observatories have also stared deeply at this region. Each advanced instrument offers researchers new details about this region, which is practically overflowing with stars.
This tightly cropped image is set within the vast Eagle Nebula, which lies 6,500 light-years away.

The James Webb Space Telescope is the world's premier space science observatory. Webb will solve mysteries in our solar system, look beyond to distant worlds around other stars, and probe the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).

Meet the first Neanderthal FAMILY! 59,000-year-old remains of individuals discovered in a cave in Russia are confirmed to be a father, his teenage daughter and two second-degree relatives
Meet the first Neanderthal FAMILY! 59,000-year-old remains of individuals discovered in a cave in Russia are confirmed to be a father, his teenage daughter and two second-degree relatives
Remains of a family of Neanderthals have been identified in a Siberian cave
This included a father, teenage daughter and a pair of second-degree relatives
The communities living in the caves were found to have low genetic diversity
They were also primarily linked by female migration between the groups
Remains of the first ever family of Neanderthals have been discovered in a cave in southern Siberia, Russia.
Researchers from the Max Planck Institute for Evolutionary Anthropology in Germany analysed the DNA of 13 individuals from two caves in the Altai Mountains.
Individuals from the Chagyrskaya cave, who date back around 59,000 years, were found to be closely related, including a father and his teenage daughter, along with a pair of second-degree relatives.
This is the first known description of social organisation of a small community of Neanderthals.
First author Laurits Skov said: 'The fact that they were living at the same time is very exciting. This means that they likely came from the same social community.
'So, for the first time, we can use genetics to study the social organisation of a Neanderthal community.'

For the study, Dr Laurits Skov and colleagues obtained and analysed genetic data from the 17 remains of 11 Neanderthal individuals from Chagyrskaya Cave and two from Okladnikov Cave. Pictured: The remains from Okladnikov Cave discussed in this study

THE CHAGYRSKAYA AND OKLADNIKOV NEANDERTHALS
Neanderthals briefly occupied the Chagyrskaya and Okladnikov caves around 54,000 years ago.
They hunted animals that migrated through the nearby river valleys, using tools made from stones that were collected dozens of miles away.
Evidence has been found of a Neanderthal family who lived in the communities, comprising of a father and his teenage daughter, as well as a pair of second degree relatives.
Short lived genetic variants that are shared between individuals suggest they all lived and died around the same time.
Genetic diversity was very low within the group, and evidence suggests that different communities were primarily linked by female migration.
Neanderthals occupied western Eurasia from around 430,000 to 40,000 years ago and are closely related to modern humans.
The species lived in Africa with early humans for millennia before moving across to Europe around 300,000 years ago.
They were later joined by humans, who entered Eurasia around 48,000 years ago.
Southern Siberia has previously been very fruitful for ancient DNA research, and is the location of the Denisova Cave, where Denisovan hominin remains were found.
Denisovans are another population of early humans who lived in Asia at least 80,000 years ago and were distantly related to Neanderthals.
The new study looked at remains found in the Chagyrskaya Cave and Okladnikov Cave, both about 60 miles (100 kilometres) away from the Denisova Cave.
Neanderthals briefly occupied these sites around 54,000 years ago, leaving several hundred thousand stone tools and animal bones.
They hunted ibex, horses, bison and other animals that migrated through the nearby river valleys, and collected raw materials for their tools from dozens of miles away.
More than 80 bone and tooth fragments of Neanderthals have also been collected, which revealed that groups inhabiting the Chagyrskaya and Okladnikov caves were closely linked.

Since the first Neanderthal draft genome was published in 2010, researchers from the German institution have sequenced a further 18 genomes from 14 different archaeological sites in Eurasia.
While this genetic data provided insights into the broader history of the ancient people, little was revealed about individual communities.
For the study, published today in Nature, Dr Skov and colleagues obtained and analysed genetic data from the remains of 11 Neanderthal individuals from Chagyrskaya Cave and two from Okladnikov Cave.
It is the largest known genetic study of Neanderthals reported to date.
These 13 people were seven men and six women, of which eight were adults and five were children and young adolescents.
This included a Neanderthal father and his teenage daughter, as well as a pair of second degree relatives: a young boy and an adult female.
These two could be cousins, aunt and nephew or grandmother and grandson.
The researchers also looked at the DNA within the Neanderthals' mitochondria, and found special kinds of genetic variants called 'heteroplasmies' shared between individuals.
These are passed through the female line and only persist for a small number of generations, suggesting that they all lived and died at around the same time.
More than 80 bone and tooth fragments of Neanderthals have been collected from the Chagyrskaya and Okladnikov caves. Pictured: Dental (left) and other (right) remains from the Chagyrskaya Cave used in this study
Genetic diversity of the Neanderthals is much lower than those recorded for any ancient or present-day human community, and is more similar to that of a group of endangered animals that are the last of their species. Pictured: Average proportion of the genome that inherited the same versions of a genomic marker from each parent (homozygosity) for Chagyrskaya Neanderthals (blue), early modern humans (orange) and present-day gorilla (green) and human populations (coloured according to the geographical region - see colour key)
The mitochondrial DNA also gave an insight into the genetic diversity within the community, which is very low and consistent with a group size of 10 to 20 people.
This is much lower than those recorded for any ancient or present-day human community, and is more similar to that of a group of endangered animals that are the last of their species.
It was also found that the genetic diversity of Y chromosomes, which pass down the male line, was a lot lower than that of the mitochondrial DNA, which is inherited from mothers.
This suggests that the communities were primarily linked by female migration, and that at least 60 per cent of the women moved to join their mates' families while the males stayed put.
Additionally, despite the proximity to Denisova Cave, these migrations do not appear to have involved Denisovans.
No evidence was found of Denisovan gene flow into the Chagyrskaya Neanderthals in the 20,000 years before they lived.
The researchers want future studies to include more individuals from other Neanderthal communities, to see if this social organisation was widespread.
Benjamin Peter, the study's last author, said: 'Our study provides a concrete picture of what a Neanderthal community may have looked like. It makes Neanderthals seem much more human to me.'
A close relative of modern humans, Neanderthals went extinct 40,000 years ago
The Neanderthals were a close human ancestor that mysteriously died out around 40,000 years ago.
The species lived in Africa with early humans for millennia before moving across to Europe around 300,000 years ago.
They were later joined by humans, who entered Eurasia around 48,000 years ago.
The Neanderthals were a cousin species of humans but not a direct ancestor - the two species split from a common ancestor - that perished around 50,000 years ago. Pictured is a Neanderthal museum exhibit
These were the original 'cavemen', historically thought to be dim-witted and brutish compared to modern humans.
In recent years though, and especially over the last decade, it has become increasingly apparent we've been selling Neanderthals short.
A growing body of evidence points to a more sophisticated and multi-talented kind of 'caveman' than anyone thought possible.
It now seems likely that Neanderthals had told, buried their dead, painted and even interbred with humans.
They used body art such as pigments and beads, and they were the very first artists, with Neanderthal cave art (and symbolism) in Spain apparently predating the earliest modern human art by some 20,000 years.
They are thought to have hunted on land and done some fishing. However, they went extinct around 40,000 years ago following the success of Homo sapiens in Europe.
Since the first Neanderthal draft genome was published in 2010, researchers have sequenced a further 18 genomes from 14 different archaeological sites in Eurasia.
Vloten van UFO's verschenen aan tientallen vliegtuigen die de Stille Oceaan overstaken
Vloten van UFO's verschenen aan tientallen vliegtuigen die de Stille Oceaan overstaken
Een onderzoeker heeft in een video de dramatische beelden van de luchtverkeersleiding vrijgegeven van Amerikaanse piloten die vreemde waarnemingen van niet-geïdentificeerde vliegende objecten (UFO's) melden terwijl ze over de Stille Oceaan vlogen.
Ervaren piloten meldden dat ze in augustus en september "felle lichten in langwerpige cirkels" hoog in de lucht zagen bewegen tijdens het vliegen van Japan en Hawaï naar de westkust van de Verenigde Staten . Zelf probeerden ze vanuit hun hutten de groep van drie tot vijf heldere objecten te filmen, die leek te vliegen in het gebied van de lucht waar het sterrenbeeld Grote Beer zich bevindt.
Deze grafiek toont de locatie en data van verschillende gerapporteerde UFO-waarnemingen, voornamelijk in de Stille Oceaan, in augustus en september.
'We hebben hier een paar vliegtuigen die in noordelijke richting vliegen en ze cirkelen, veel hoger dan wij. Enig idee wat ze zijn?'vroeg Mark Hulsey, een piloot die een Gulfstream-chartervliegtuig bestuurt voor de kust van Los Angeles.
De piloot beschreef dat hij daar "misschien drie vliegtuigen " zag en 23 minuten later belde hij het Air Route Traffic Control Centre (ARTCC) met de mededeling "er zijn er nu zo'n zeven" en schatte dat ze "ten minste 5 of 10.000 voet boven de grond waren". ." boven ons."
Deze afbeelding toont de helderheid van de UFO in vergelijking met de drie sterren (binnen rode cirkels).
Gevraagd door de controller om meer details, voegde Hulsey eraan toe: " Ze blijven maar in cirkels draaien ." "Ik was een F-18-piloot bij het Korps Mariniers en ik zeg je dat ik veel onderscheppingen heb gedaan, ik heb nog nooit zoiets gezien", vertelde hij aan verslaggevers.
Chris Van Voorhis, 63, vertelde dat hij tussen de drie en vijf objecten zag, veel helderder dan de sterren om hem heen, vervagend zonder waarneembaar patroon en bewegend in een cirkelvormige "racebaan" -beweging terwijl hij in augustus van Honolulu naar Los Angeles vloog.
De ervaren piloot zei dat de objecten zich in een baan om de aarde of zelfs verder in de ruimte leken te bevinden , gezien hun voortdurende positie nabij het sterrenbeeld Ursa Major terwijl ze urenlang over de oceaan vlogen.
"De andere luchtvaartmaatschappijen zeiden: "Hé, zie je wat wij zien?" , herinnerde de ervaren piloot zich. "Het waren lichten die heel intens aangingen, je zag ze bewegen en toen gingen ze uit" en hij verduidelijkte dat het geen satellieten konden zijn omdat ze lineair en in dezelfde richting zouden bewegen.
Ervaren piloten meldden dat ze urenlang "felle lichten in langwerpige cirkels" hoog in de lucht zagen bewegen terwijl ze routes van Japan en Hawaï naar de Amerikaanse westkust vlogen.
"Het moest in een zeer, zeer hoge baan om de aarde zijn, of zelfs in de ruimte, vrij ver van alles wat een satelliet zou kunnen zijn, want elke keer dat we het zagen, bevond het zich in de rechter benedenhoek van de Grote Beer, wat er ook gebeurde. deel van de wereld waarin we ons bevonden. Het duurde zo lang dat het eigenlijk bijna saai werd."
Van Voorhis zei dat UFO-waarnemingen heel gewoon zijn onder piloten: "Van mijn pilootvrienden heeft minstens 50% een of andere anomalie gezien", zei hij.
Ben Hansen, een voormalig FBI-agent en presentator van het Discovery+ -kanaal " UFO Witness "-programma, verzamelde tussen 6 augustus en 23 september accounts van piloten van meer dan 15 commerciële vluchten voor Southwest Airlines , Hawaiian Airlines en anderen . dezelfde lichten aan de hemel als Van Voorhis.
"Veel van deze piloten hebben er alle vertrouwen in dat de lichten niet slechts in één richting gingen, maar in beide richtingen, wat zeer ongebruikelijk is voor satellieten. In het geval van Hulsey zouden ze uit het noorden komen en dan over hun schip gaan, waar hij moest zijn nek uitstrekken om ze vanaf het bladerdak te kunnen zien," zei hij.
Piloot Chris Van Voorhis vertelde dat hij tussen de drie en vijf UFO's zag, veel helderder dan de omringende sterren, vervagend zonder waarneembaar patroon en bewegend in een cirkelvormige "racebaan" -beweging, terwijl hij in augustus van Honolulu naar Los Angeles vloog.
"In dit geval hebben we een wereldwijd fenomeen van West-Japan tot Oost-Miami. Wat het ook is, piloten zien het vanaf de andere kant van de wereld," zei hij.
Maar Hansen zei dat er momenteel geen goede procedure is voor het melden van dergelijke waarnemingen, zelfs niet van vreemde objecten die een veiligheidsrisico kunnen vormen voor commerciële luchtvaartmaatschappijen.
