By a stroke of luck, a team led by Dutch Ph.D. student Martijn Oei has discovered a radio galaxy of at least 16 million light-years long. The pair of plasma plumes is the largest structure made by a galaxy known thus far. The finding disproves some long-kept hypotheses about the growth of radio galaxies.
A supermassive black hole lurks in the center of many galaxies, which slows down the birth of new stars and therefore strongly influences the lifecycle of the galaxy as a whole. Sometimes, this leads to tumultuous scenes: the black hole can create two jet streams, that catapult the building material for baby stars out of the galaxy at almost the speed of light. In this violent process, the stardust heats up so much that it dissolves into plasma and glows in radio light. The international team of researchers from Leiden (The Netherlands), Hertfortshire, Oxford (both UK), and Paris (France) have now collected that light—with the pan-European LOFAR telescope, whose epicenter lies in a marshy Dutch 'radio dark' nature reserve, where your smartphone deliberately loses signal.
Record length
The picture of the two plasma plumes is special, because never before scientists saw a structure this big made by a single galaxy. The discovery shows that the sphere of influence of some galaxies reaches far from their direct environment. How far, exactly? That is hard to determine. Astronomical pictures are taken from a single viewpoint (Earth), and therefore do not contain depth.As a result, scientists can only measure a part of the radio galaxy length: a low estimate of the total length. But even that lower bound, of more than 16 million light-years, is gargantuan, and comparable to one hundred Milky Ways in a row.
Visible with the naked radio eye
Because Earth does not occupy a special place in the universe, it was never very likely that such a largest galactic structure would reside in our own backyard. And indeed: the radio giant is three billion light-years away from us. Despite that mind-boggling distance, the giant looms as large in the sky as the moon—an indication that the structure had to have a record length. The fact that the radio eyes of the LOFAR telescope only saw the giant just now, is because the plumes are relatively faint. By reprocessing a set of existing images in such a way that subtle patterns stood out, the scientists were suddenly able to spot the giant.
The giant Alcyoneus
The researchers named the giant structure Alcyoneus, after the son of Ouranos, the Greek primordial god of the sky. This mythological Alcyoneus was a giant that fought against Heracles and other Olympians for supremacy over the cosmos. In the world-famous Pergamon Altar in Berlin, a sculpture of this Alcyoneus is carved out.
Ghostly dance
Alcyoneus' plumes possibly reveal information about the mostly elusive filaments of the Cosmic Web. The Cosmic Web is another name for the contemporary, grown-up universe, that looks like a network of threads and nodes that astronomers call filaments and clusters, respectively. The galaxies in filaments and clusters are clearly visible themselves, but detecting the medium between galaxies has only been successful in clusters—barring a handful of exceptions. Could Alcyoneus change this?
Because Alcyoneus, just like the Milky Way, inhabits a filament, its plumes feel a headwind while moving through the medium. This subtly changes the direction and shape of the plumes: They perform a slow dance with an invisible partner. For many years, scientists have proposed that the shapes of and pressures in the plumes of radio galaxies could relate to filament properties, but never before did they find an example where that connection is as plausible as with Alcyoneus. Namely, Alcyoneus' plumes are so big and rarefied that the surrounding medium can relatively easily mold them.
Black holes are cosmic mainstays
The Cosmic Web retains its form because the attractive force of gravity is compensated by the heat pressure of the medium in filaments and clusters. In the past two decennia it has become clear that the glowing stardust that jet streams eject from galaxies, keeps the Web warm. In this way, the central black holes in galaxies contribute to sustain the large-scale structure of our universe. That is extra noteworthy because black holes are very small compared to filaments and clusters. It is as if something the size of a marble regulates the Earth's temperature.
Mysterious origin
What has given Alcyoneus its record length, remains a mystery for now. The scientists first thought of an exceptionally massive black hole, an extensive stellar population (and so a lot of stardust), or extraordinarily powerful jet streams. Surprisingly enough, Alcyoneus appears to be less than average on all these aspects compared to its smaller sisters and brothers. In the times ahead, the team will therefore now investigate whether the environments of radio galaxies could explain the growth of giants instead.
Astronomen ontdekken per toeval grootste radiosterrenstelsel ooit: “Vergelijkbaar met honderd Melkwegen op een rij”
Per toeval heeft een team van astronomen het grootste radiosterrenstelsel ooit ontdekt. Het stelsel is minstens 16 miljoen lichtjaar lang, vergelijkbaar met honderd Melkwegen op een rij. Dat meldt de Universiteit van Leiden. De structuur voldoet niet aan eerdere ideeën over de vorming van een radiostelsel, aldus onderzoeksleider Martijn Oei.
Voor een ander onderzoek moesten bestaande astronomische foto’s opnieuw gemaakt worden, maar dan op lage resolutie. Daarop zag Oei twee grote pluimen, het tot dan toe nog onontdekte radiosterrenstelsel. “Ik wist toen nog nauwelijks wat radiosterrenstelsels waren. Met een online calculator probeerde ik even uit te rekenen hoe groot dat stelsel dan moest zijn, en dat was groter dan waar ik ooit van had gehoord.” Radiostelsels zijn uitvloeisels van sterrenstelsels, legt Oei uit. In een sterrenstelsel vindt een soort eruptie plaats die materiaal van het sterrenstelsel naar buiten schiet.
Bestaande theorieën overboord
Samen met het team probeerde hij te achterhalen hoe het mogelijk was dat dit radiostelsel zo ver reikt. De bestaande oorzaken moesten de onderzoekers echter één voor één overboord gooien. “Misschien was er een groot zwart gat, bevatte het stelsel heel veel sterren of waren de straalstromen heel krachtig”, zegt Oei. “Maar dat was allemaal niet het geval, het stelsel is in die opzichten heel gemiddeld.” In de studie noemen de onderzoekers het stelsel ook wel “verdacht gewoon”.
De komende tijd gaan de wetenschappers daarom meer onderzoek doen naar de oorzaak voor de grootte van het radiosterrenstelsel. De indrukwekkende vondst kreeg de naam Alcyoneus, naar de machtigste van de Giganten (een soort reuzen in de Griekse mythologie). “Er is nog één theorie die we moeten testen”, vertelt Oei. “Het zou kunnen dat het stelsel zich in een ijle omgeving bevindt, waardoor het radiostelsel verder reikt.”

Even groot als maan
Door het onderzoek is in elk geval duidelijk dat sommige sterrenstelsels tot ver buiten hun directe omgeving nog invloed hebben op hun radiostelsel. Het is ook mogelijk dat Alcyoneus nog groter is dan 16 miljoen lichtjaar. De Aarde bevindt zich op zo’n 3 miljard lichtjaar van het radiosterrenstelsel. Van bij ons gezien zou het stelsel ongeveer even groot aan de hemel moeten zijn als de maan.
De wetenschappers van de universiteiten in Leiden, Hertfordshire, Oxford en Parijs publiceren het onderzoek binnenkort in het vakblad ‘Astronomy & Astrophysics’.
A supermassive black hole has been discovered hiding inside a cloud of cosmic dust at the center of a galaxy 47 million light years from the Earth.
Detailed images of the dust cloud were taken using the European Southern Observatory's Very Large Telescope Interferometer (ESO's VLTI), in Chile.
They turned the observatory to the galaxy Messier 77, which is about 47 million light years away, finding a thick ring of cosmic dust, hiding a supermassive black hole.
Where exactly within this cloud of dust the black hole sits has been a mystery for decades, but the team used the detailed images from VLTI to measure the temperature at different points within the cloud, creating a map.
Known as an active galactic nuclei (AGN), the cloud surrounding the black hole are feeding it, letting off intense light that can outshine stars in the galaxy.
These are some of the brightest and most mysterious objects in the universe, sitting at the heart of galaxies - and the findings could help pin down the history of the supermassive black hole at the center of the Milky Way, Sagittarius A*.
This image, captured with the MATISSE instrument on ESO’s Very Large Telescope Interferometer, shows the very inner region of the active galaxy Messier 77.
Before the gas and dust in an AGN is eaten up by the black hole, the material spirals towards it, releasing huge amounts of energy in the process, often outshining all the stars in the galaxy - as viewed by telescopes on the Earth.
Finding the black hole, which emits no light of its own, is a tricky process that involves solving a detailed puzzle.
The team used detailed images, and analysis of changes in dust temperature to build a picture of the dust and pinpoint where the black hole must lie.
The astronomers suggest the dust with the black hole at its core supports a decades-old model, known as the Unified Model of AGNs.
Violeta Gamez Rosas, lead researcher, said: 'The real nature of the dust clouds and their role in both feeding the black hole and determining how it looks when viewed from Earth have been central questions in AGN studies over the last three decades.
Spiral galaxy Messier 77 and its surroundings are visible here. Messier 77 appears at the centre and the edge-on galaxy NGC 1055 to its upper-right
ESO's Very Large Telescope (VLT) has captured a magnificent face-on view of the barred spiral galaxy Messier 77. Hidden at the center is a supermassive black hole
BLACK HOLES HAVE A GRAVITATIONAL PULL SO STRONG NOT EVEN LIGHT CAN ESCAPE
Black holes are so dense and their gravitational pull is so strong that no form of radiation can escape them - not even light.
They act as intense sources of gravity which hoover up dust and gas around them. Their intense gravitational pull is thought to be what stars in galaxies orbit around.
How they are formed is still poorly understood. Astronomers believe they may form when a large cloud of gas up to 100,000 times bigger than the sun, collapses into a black hole.
Many of these black hole seeds then merge to form much larger supermassive black holes, which are found at the centre of every known massive galaxy.
Alternatively, a supermassive black hole seed could come from a giant star, about 100 times the sun's mass, that ultimately forms into a black hole after it runs out of fuel and collapses.
When these giant stars die, they also go 'supernova', a huge explosion that expels the matter from the outer layers of the star into deep space.
Whilst no single result will settle all the questions we have, we have taken a major step in understanding how AGNs work.'
These bright phenomena were first spotted in the 1950s, and astronomers have been curious about them ever since.
Using the Very Large Telescope Interferometer, the researchers have taken a step towards understanding how they work and what they look like up close.
Astronomers know there are different types of AGN, with some appearing brighter than others, and the model states that despite their differences, they all have the same basic structure – a supermassive black hole surrounded by a thick ring of dust.
According to the 30-year old Unified Model of AGNs, which these observations confirm, any difference in appearance between AGNs results from the angle at which the black hole and its thick ring are seen from Earth.
The type of AGN seen depends on how much of the space dust ring blocks the black hole from view, sometimes completely hiding it.
Astronomers had found some evidence to support the Unified Model before, including spotting warm dust at the centre of Messier 77.
However, doubts remained about whether this dust could completely hide a black hole and hence explain why this AGN shines less brightly in visible light than others.
Ms Gamez Rosas said: 'Our results should lead to a better understanding of the inner workings of AGNs. They could also help us better understand the history of the Milky Way, which harbours a supermassive black hole at its centre that may have been active in the past.'
This chart shows the location of the active galaxy Messier 77 in the constellation of Cetus (The Sea Monster). It shows most stars visible to the unaided eye on a dark and clear night
This illustration shows what the core of Messier 77 might look like. As other active galactic nuclei, the central region of Messier 77 is powered by a black hole that is surrounded by a thin accretion disc, which itself is surrounded by a thick ring or torus of gas and dust
The team also used data from the Atacama Large Millimeter/submillimeter Array, co-owned by ESO, and the National Radio Astronomy Observatory’s Very Long Baseline Array to construct their picture.
The researchers are now looking to use ESO's VLTI to find more supporting evidence of the Unified Model of AGNs by considering a larger sample of galaxies.
Team member Bruno Lopez, the MATISSE Principal Investigator at the Observatoire de la Côte d'Azur in Nice, France, said: 'Messier 77 is an important prototype AGN and a wonderful motivation to expand our observing programme and to optimise MATISSE to tackle a wider sample of AGNs.'
ESO's Extremely Large Telescope (ELT), set to begin observing later this decade, will also aid the search, providing results that will complement the team's findings and allow them to explore the interaction between AGNs and galaxies.
THE VERY LARGE TELESCOPE IS A POWERFUL GROUND-BASED INSTRUMENT IN CHILE
The European Southern Observatory (ESO) built the most powerful telescope ever made in the Atacama Desert of northern Chile.
It is called the Very Large Telescope (VLT) and is widely regarded as one of the most advanced optical instruments ever made.
It consists of four telescopes, whose main mirrors measures 27 feet (8.2 metres) in diameter.
There are also four movable six feet (1.8 metre) diameter auxiliary telescopes.
The large telescopes are called Antu, Kueyen, Melipal and Yepun.
The European Southern observatory (ESO) built the most powerful telescope ever made in the Atacama Desert of northern Chile and called it the Very Large Telescope (VLT).
The first of the Unit Telescopes, 'Antu', went into routine scientific operations on April 1, 1999.
The telescopes can work together to form a giant 'interferometer'.
This interferometer allows images to be filtered for any unnecessary obscuring objects and, as a result, astronomers can see details up to 25 times finer than with the individual telescopes.
It has been involved in spotting the first image of an extrasolar planet as well as tracking individual stars moving around the supermassive black hole at the centre of the Milky Way.
It also observed the afterglow of the furthest known Gamma Ray Burst.
Superzwaar zwart gat verscholen in een ring van kosmisch stof
In het centrum van het sterrenstelsel Messier 77 is een wolk van kosmisch stof waargenomen die een superzwaar zwart gat aan het zicht onttrekt, zo heeft de Europese Zuidelijke Sterrenwacht (ESO) woensdag bekendgemaakt. De ontdekking bevestigt voorspellingen van zo'n dertig jaar geleden en geeft astronomen nieuw inzicht in de 'actieve galactische kernen', die tot de helderste en meest raadselachtige objecten in het heelal behoren.
Actieve galactische kernen (Engelse afkorting: AGNs) zijn extreem energetische bronnen, aangedreven door superzware zwarte gaten, die zich in het centrum van sommige sterrenstelsels bevinden. Deze zwarte gaten voeden zich met grote hoeveelheden kosmisch stof en gas. Voordat dit materiaal wordt opgeslokt, spiraalt het naar het zwarte gat, en daarbij komen enorme hoeveelheden energie vrij. Daardoor straalt een actieve kern vaak feller dan alle sterren in het omringende sterrenstelsel bij elkaar. Al vanaf het moment dat wetenschappers deze heldere objecten in de jaren vijftig voor het eerst opmerkten, zijn astronomen nieuwsgierig naar AGNs.
Een team onder leiding van Violeta Gámez Rosas van de Universiteit Leiden loerde nu met de VLT-telescoop in Chili naar het centrum van het sterrenstelsel Messier 77, ook bekend als NGC 1068. De vorsers ontdekten een dikke ring van kosmisch stof en gas die een superzwaar zwart gat verbergt. De ontdekking levert cruciaal bewijs voor een dertig jaar oude theorie die het Unified Model of AGNs wordt genoemd.
Er zijn verschillende soorten AGN's. Sommige AGN's produceren bijvoorbeeld uitbarstingen van radiostraling en andere niet; en sommige AGN's zijn heldere bronnen van zichtbaar licht, terwijl andere - zoals Messier 77 - meer getemperd zijn. Het Uniform Model stelt dat alle AGN's - ondanks hun grote onderlinge verschillen - dezelfde basisstructuur hebben: ze bestaan uit een superzwaar zwart gat, omgeven door een dikke ring van stof.
Volgens het model zijn de verschillende verschijningsvormen van AGN's eenvoudigweg het gevolg van de hoek waaronder we het zwarte gat en de dikke ring vanaf de Aarde waarnemen. Het soort AGN hangt af van de mate waarin de ring het zwarte gat aan het zicht onttrekt en in sommige gevallen zelfs helemaal verbergt.
Now look at this! Its a UFO sphere on live cam, but its over the Washington DC area...not far from the US Presidential White House. That really tells me a lot right there! Aliens clearly were trying to observe and record the US presidents emotions and thought using telepathic abilities. President Biden is under a lot of stress right now from Russia wanting to go to war with Ukraine...and China doing the same with Taiwan. Stress levels in the White House right now are off the charts. Nuclear war is a possibility. And Aliens want to know, not so much for saving humanity as much as keeping their planet safe. Yes, this planet belonged to aliens long before humanity even existed. And we claim it to be ours. It's like a kid saying the house is belongs to him...but it's really his fathers. This video is 100% proof that aliens are watching US President Biden ever move, feeling and thought.

The mind blowing bizarre and most mysterious Alien Encounters of all.
40 years ago, a remote forest in Suffolk was the scene of one of the most famous purported UFO sightings in history. The Rendlesham UFO sighting. So what happened, and will we ever know for sure? Larry Warren and Georgina Bruni claim to have witnessed alien life forms. They saw a giant object that had landed on the earth’s surface. They say the massive shape was more than 50ft wide, had a strong definition, was multiple colors, and the most important thing about this incident was that were more than 30 witnesses in this sighting. The United States Air Force (USAF) security personnel stationed at nearby RAF Woodbridge had even reported seeing strange lights in the surrounding forest.

Planet Found in the Habitable Zone of a White Dwarf
Planet Found in the Habitable Zone of a White Dwarf
Most stars will end their lives as white dwarfs. White dwarfs are the remnant cores of once-luminous stars like our Sun, but they’ve left their lives of fusion behind and no longer generate heat. They’re destined to glow with only their residual energy for billions of years before they eventually fade to black.
Could life eke out an existence on a planet huddled up to one of these fading spectres?
For life to exist around a white dwarf, the white dwarf would have to have planets in its slowly shrinking habitable zone. Astronomers have found what appear to be planets in the habitable zone of a white dwarf about 117 light-years away. The planet might be nestled in a protoplanetary disk of debris.
A new study led by researchers from the University College of London announces the findings. The title is “Relentless and complex transits from a planetesimal debris disc.” It’s published in the Monthly Notices of the Royal Astronomical Society, and the lead author is Professor Jay Farihi from the UCL Department of Physics & Astronomy.
“This is the first time astronomers have detected any kind of planetary body in the habitable zone of a white dwarf.”
Professor Jay Farihi, UCL Dep’t. of Physics and Astronomy.
The star’s name is WD1054–226. The researchers behind this work observed WD1054-226 for 18 nights with the ESO’s New Technology Telescope (NTT) at their La Silla Observatory, observing dips in starlight as something passed between us and the star. They used the NTT’s ULTRACAM high-speed camera to capture data images of the white dwarf. They also examined data on the same star from NASA’s Transiting Exoplanet Survey Satellite (TESS.)

What were the results of those observations?
The team found dips in light that they interpret as 65 clouds of planetary debris. The clouds are evenly spaced and orbit the white dwarf every 25 hours. What causes such regularity? The researchers say that a planet must be there, which forces these debris clouds into a precise orbital pattern. They say the planet is similar in size to rocky planets in our Solar System and that it’s only about 2.5 million km (1.55 million miles) from the star. That’s about 1.7% of the distance between Earth and the Sun.
Alongside the regular dips in starlight is an ever-present obscuration that the team says is debris in a planetary disk around the star. These structures are in a region that would have been overcome when the white dwarf went through its preceding red giant phase. It’s doubtful that any of these structures could have survived the red giant phase, so they must have formed more recently in the aftermath. If there is a planet in the habitable zone, it can’t be a hold-over from the star’s previous life as a main-sequence star. If all of the circumstances lined up just right—and that’s an enormous if—life would potentially have about two billion years to do its thing on the purported planet, with one of those billions in the future.
“This is the first time astronomers have detected any kind of planetary body in the habitable zone of a white dwarf,” said Professor Farihi. The planet’s presence is inferred from the regular dips in the light of all the other objects in the system.
This figure from the study shows the first three nights of ULTRACAM observations of WD1054-226. The figure shows a notable and easily recognized recurring feature, the double-dip structure that recurs every 25.2 hours and occurs just before hours 2, 27, and 52. The authors say that “Using this structure as a visual anchor, the adjacent, antecedent, and subsequent transits can all be seen to have the same morphology over all three nights.”Image Credit: Farihi et al. 2022.
“An exciting possibility is that these bodies are kept in such an evenly-spaced orbital pattern because of the gravitational influence of a nearby major planet,” Professor Farihi said in a press release. “Without this influence, friction and collisions would cause the structures to disperse, losing the precise regularity that is observed. A precedent for this ‘shepherding’ is the way the gravitational pull of moons around Neptune and Saturn helps to create stable ring structures orbiting these planets.”

Not all of the team’s observational data repeats with predictable regularity. The researchers also found at least two transient drifters in the data. “At least two drifting transits may be seen to recur over three or more nights,” the team writes in their paper. The faster of the two has a period of about 22.9 hours, and the slower of the two has a period of about 25.5 hours.
This figure represents ULTRACAM data showing two transients. The more rapid of the two is on the left in blue, and the slower one is on the right in green. Image Credit: Farihi et al. 2022.
There are indications of other drifters, but their data gets progressively weaker. The team explains this in their paper: “There are a number of dips that are either transient or cannot be confidently shown to recur, which are thus challenging to quantify. It is important to note that the process … can only effectively remove recurring signals where multiple-night coverage is available at a given phase. Thus, some phases will suffer artifacts in this process, especially where coverage – either in the light curve or subtracted data – includes only a single night. Thus, not all light-curve residual structures are real.” Such are the ways of astronomy.
The 65 separate structures the astronomers found could be moons or nascent moons. But if they are, they’re nothing like the moons we’re accustomed to. “The moon-sized structures we have observed are irregular and dusty (e.g. comet-like) rather than solid, spherical bodies. Their absolute regularity is a mystery we cannot currently explain,” said lead author Farihi.
In their paper, the authors explain the 65 structures, saying that “There is no evidence for solid-body transits in any of the data, and the underlying transit sources are presumably relatively small but with extended comae of dust and gas.” That’s where their “comet-like” description comes from. “It cannot yet be determined what fraction of the stellar disc is constantly occluded, which could be significant,” they write. “However, the duration of the transit events provides clear indications that the occulting clouds are non-spherical.”
The data is intriguing, but the authors are the first to point out that any firm conclusions are premature. “The possibility of a major planet in the habitable zone is exciting and also unexpected; we were not looking for this. However, it is important to keep in mind that more evidence is necessary to confirm the presence of a planet. We cannot observe the planet directly, so confirmation may come by comparing computer models with further observations of the star and orbiting debris,” Professor Farihi said.
If there are indeed clouds of material orbiting the white dwarf, they’re likely outside the Roche limit. The authors say that debris clouds probably come from collisions or tidal disruption events. “From a dynamical and evolutionary perspective, the origin of the large occulting clouds is likely the result of tidal disruption or collisions in the vicinity of the Roche limit,” they write in their conclusion.
It’ll be up to further observations with the James Webb Space Telescope to provide better data. The JWST has the power to better define the debris disk and its components. But if there is a roughly Earth-sized rocky planet there, it’s an intriguing possibility with liquid water potential.
Marginally habitable situations may be relatively common in the Milky Way and the Universe. Life might arise countless times and never evolve the complexity that life on Earth has become. The Moons of our Solar System might harbour life for some time. Mars may have harboured life for some time.
Now, maybe, we can add white dwarf planets to that list.
SpaceX ‘destacks’ Starship and Super Heavy: what’s next?
SpaceX ‘destacks’ Starship and Super Heavy: what’s next?
On February 14th, a bit less than four days after the giant rocket was used as a backdrop for CEO Elon Musk’s first Starship presentation in years, SpaceX lifted Starship off of the Super Heavy booster and lowered the upper stage to the ground.
In early August 2021, the same pair – Booster 4 and Ship 20 – were stacked for the first time for what was described as a fit test. After briefly forming the largest rocket ever assembled, the stages were ‘destacked’ about an hour later and would ultimately return to the Starbase factory for finishing touches. Six months, one ship cryoproof, three booster cryoproofs, and three ship static fire tests later, Ship 20 and Booster 4 were once stacked to form a massive 119-meter-tall (390 ft) tall rocket
This time around, Starship S20 was stacked on top of Super Heavy B4 not with a giant crane but with a ‘launch and integration tower’ that had been outfitted with three giant arms in the interim. The tower’s main pair of arms – ‘chopsticks’ – lifted the ~100-ton (~220,000 lb) Starship almost 100 meters off the ground, swung it over Super Heavy, and then carefully lowered the stages until Super Heavy was able to latch on.
On its first true demonstration, the complex process went far smoother than anyone outside of SpaceX expected, taking the tower just four or so hours from the start of the lift to hard mate. On February 10th, shortly before Musk’s Starship update, SpaceX even opened the ‘chopsticks’ to their full breadth, leaving all of Starship S20’s weight on Super Heavy B4 and also demonstrating what the pad will likely look like moments before the first orbital Starship launch.
On February 14th, after about four days fully stacked, the tower arms reattached to Ship 20, detached from Super Heavy, and lowered the Starship back to the ground, where it was eventually installed on a transport stand. Later that night and early the next day, SpaceX then moved the ship to a small concrete pad adjacent to the launch tower that’s believed to be meant for cryogenic proof testing. It’s unclear why SpaceX didn’t tested the fully stacked Starship given that both ship and booster have already completed multiple cryogenic proof tests (or wet dress rehearsals with real propellant) over the last few months.

It’s also unclear what more SpaceX can gain from testing Ship 20 on the ground, short of full-stack operations. On Sunday, February 13th, SpaceX did, however, begin filling the orbital launch site’s fuel tanks with liquid methane (LCH4) for the first time. It’s possible that instead of using Ship 20 to test any aspect of the relatively ancient Starship prototype, SpaceX will use Ship 20 to test the orbital tank farm – particularly the fuel side of the farm, which has yet to be tested. Perhaps after testing those systems on the ground, SpaceX will re-stack Ship 20 and Booster 4 and perform a similar wet dress rehearsal to test the tower’s plumbing, the ship-fueling arm, and the overall structural integrity of the fully-stacked rocket.
SpaceX has test windows tentatively scheduled on February 16th, 17th, and 18th.
This is a video by Terrys Theories channel on Youtube. Hes a friend who does some deep investigations into sightings and here he does it again. He got a mail in report about two glowing pink lights in the sky on his way home from work. the lights seem to be huge, about the size of a minivan and the objects shape is very similar to many others seen in past UFO reports. Are aliens looking over Ukraine...trying to prevent, help or just watch and record the future events with Russia? The pressure on Ukraine is huge right now...possible war with Russia may be taking place already as you read this. Aliens often are seen during such events, like the Foo Fighter glowing whit spheres during WWII. Mind boggling stuff.

UFO Flashes To Eyewitnesses At Beach In Brazil, Feb 2, 2022, Video, UFO Sighting News.
Date of sighting: Feb 2, 2022
Location of sighting: Brazil beach
The spectators watching this UFO over a beach in Brazil really excited the onlookers. You can hear them gasp and ask questions of what it could possibly be. This UFO flashes several times...because its trying to say hello to the people below in the only way its allowed. Every alien species has different contact rules about humans...this one has to keep a distance, but apparently there was no rule about deliberately flashing to catch humans attentions below. Awesome work around and goes to show...even aliens have rules, mandates, necessary things they need to follow. They seem a bit more like us now don't they?
Kid records unknown glowing object...another eyewitness in India UFO Sighting, Video, Feb 14, 2022.
Kid records unknown glowing object...another eyewitness in India UFO Sighting, Video, Feb 14, 2022.

This is another video of the India event. A young boy recorded the UFO over his area. Since the eyewitness is a child...I didn't want to ask any more information so that his safety is kept. A childs' safety is always most important. But this is clearly the exact same glowing object seen in two earlier posts I made today. Absolutely breaking raw video. Seen over many different cities in India! Aliens are clearly trying to be noticed.

Date of sighting: Feb 14, 2022
Location of sighting:Auroville, India
This is a mind-blowing event that was seen by thousand of people in India so I'm expecting many videos of this event. I just did an earlier post about the same event, but different eyewitness. Here the eyewitness gives his account and shows raw footage of two eyewitnesses at two different locations. Aliens are really trying to get noticed so that they can make humans accustomed to the existence of other intelligent species...little by little. This is undeniable proof that aliens exist. However...I'm sure the India gov willl come up with some excuse to blame it on military exercises, Venus, swamp gas or some other lame excuse to try to keep the public in the dark about the truth.

This eyewitness talks about his sighting that took place in India. He states,
"I was walking along the beach this morning. It was around 6 o'clock, and the sky was still dark. And I noticed a strange pattern of clouds. Which was really amazing. It was as if the cloud was painted in a very strange way. So I was standing and staring at the cloud, and I turned around and looked in the other direction and noticed this strange object. It was like a torch light. It stayed for a while and then disappeared." He then goes on to talk about calling up a friend in another city who also saw the same thing and they compared videos of the event.

Location of sighting: Electric City, Bangalore, India
An eyewitness recorded two short videos of some unknown sky phenomenon the both frightened and excited his community. The UFO left a glowing trail with it as well as it being escorted by a smaller glowing sphere behind it. You can hear the excitement and dismay as these UFOs pass overhead. I do not thing they are rockets or missiles. The India news doesn't have any mention of rockets this week at all. These two glowing objects are genuine UFOs. Even the eyewitness titles the video, "UFO spotted in Electronic city of Bangalore || Live footage captured on camera!" And this witness is 100% correct. He witnessed a rare and important event.
PHOENIX LIGHTS 2022?? UFOs multiplying over Phoenix, Arizona 14-Feb-2022
PHOENIX LIGHTS 2022?? UFOs multiplying over Phoenix, Arizona 14-Feb-2022
Strange lights were recorded in the sky above Phoenix in Arizona on 14th February 2022. Another episode of famousPhoenix lights?
Witness report:
With the binocs I could see they were flickering different colors like a juul in party mode when it goes all rainbowy. Some would move apart from the spot they were staying in and then come back. We drove to get closer and then it was just one light and that disappeared eventually. I’m skeptical and was just talking today about how skeptical I am of stuff people say they see in the sky and then this happened lol. Thought they might be lanterns till I saw through the binocs. I’d like to see the footage you got. It’d be cool to see that wheel drawing in the sky. This was recorded with an iPhone 13 zoomed into the horizon at night. We were south of Maricopa, Arizona facing north towards Maricopa and Phoenix at 7:51. The lights were flickering different colors and appearing and disappearing. Lasted about 20 minutes. I had binocs and could see them clearer than this video.
We've never seen a planet being formed in this much detail.

An international team of astronomers has managed to capture some extraordinarily rare images of planetary systems being born, hundreds of light-years away.
While we’ve seen images of “protoplanetary disks” before, we’ve never seen the process captured in such detail.
An team of astronomers has managed to take some extremely rare images of the process of planetary systems being born hundreds of light-years away. Kluska et al.
“In [earlier] pictures, the regions close to the star, where rocky planets form, are covered by only few pixels,” lead author Jacques Kluska, from KU Leuven in Belgium, said in a statement.
The images show the inner areas around young stars where planets start taking shape, accumulating matter from dust and gas. Dust grains build up into larger rocks, some of which eventually grow into entire rocky planets.
“We needed to visualize these details to be able to identify patterns that might betray planet formation and to characterize the properties of the disks,” Kluska said.
The researchers had to use a relatively new imaging technique called infrared interferometry at the European Southern Observatory (ESO) in Chile to capture the images.
The technique doesn’t produce an image directly. Using mathematical models — not unlike the way the first-ever images of a black hole were created — the team was able to separate the disks from the light emitted by the star itself.
The level of detail of the new images is astonishing.
“Distinguishing details at the scale of the orbits of rocky planets like Earth or Jupiter (as you can see in the images) — a fraction of the Earth-Sun distance — is equivalent to being able to see a human on the Moon, or to distinguish a hair at a 10 km distance,” Jean-Philippe Berger, principal investigator from the Université Grenoble-Alpes, France, explained in the statement.
So what did they end up seeing in the new images? Brighter and darker spots of light could be a sign that “there could be instabilities in the disk that can lead to vortices where the disk accumulates grains of space dust that can grow and evolve into a planet,” according to Kluska.
NASA deelt voor het eerst beelden van mysterieuze planeet Venus
NASA deelt voor het eerst beelden van mysterieuze planeet Venus
NASA deelt voor het eerst beelden van de planeet Venus. Een reizende ruimtesonde toont een gedetailleerde kijk op het oppervlak. Door middel van een wide-field imager kan de sonde verschillende kenmerken waarnemen, zoals continentale regio’s, vlakken en plateaus. Volgens wetenschappers wijst het er zelfs op dat Venus ooit bewoonbaar is geweest.
Voor het eerst werden er beelden van het oppervlak van Venus in zichtbaar licht - het licht dat het menselijk oog kan zien - vanuit de ruimte vastgelegd. Het is een absolute mijlpaal voor het onderzoek naar de raadselachtige planeet die iedere nacht aan onze hemel schittert. Bekijk hierboven de beelden van de primeur.
De afbeeldingen kunnen aanwijzingen bevatten over het mysterieuze verleden van Venus.
Verbluffende beelden gemaakt door NASA's Parker Solar Probe. De allereerste zichtbare glimp van het gloeiend hete oppervlak van Venus gegeven, waardoor continenten, vlaktes en plateaus op de vulkanische wereld zichtbaar werden.
Terwijl ze onder de dikke en giftige Venus-wolken tuurden met het Wide-field Imager for Parker Solar Probe (WISPR)-instrument, zagen NASA-wetenschappers een hele reeks geologische kenmerken oplichten in de zwakke gloed van het nachtelijke oppervlak van Venus, naast een lichtgevende halo van zuurstof in de atmosfeer van de planeet.

Aliens Create Heart In Sky Over Florida, Feb 14, 2016, UFO Sighting News.
Date of sighting:Feb 14, 2016
Location of sighting: Florida, USA
Source: Twitter account @SaechemClouds
Although this photo is from six years ago, it's fitting for the day. Now this photo was posted to twitter by a young woman who works in a the Florida Cloud Appreciation Society. She calls herself a cloud spotter that that she surely is. She saw a heart shaped cloud in the sky. I quickly tweeted back to her saying, "fantastic catch, but also...what is that round object leaving the heart with a trail behind it? You saw them...and they...saw you." There is a UFO in the photo. The UFO is semi cloaked in a cloud sphere disguise and is moving away from the top of the heart. There is a cloud trail behind it. It looks like aliens have a heart too.
