Searching for Outbursts in the Ground-Based Photometry of 67P Churyumov-Gerasimenko by Daniel Gardener et al. on Monday 17 October 67P/Churyumov-Gerasimenko is a Jupiter-family comet that was the target of the Rosetta mission, the first mission to successfully orbit and land a probe on a comet. This mission was accompanied by a large ground-based observing campaign. We have developed a pipeline to calibrate and measure photometry of comet 67P during its 2016 perihelion passage, making use of all visible wavelength broadband imaging collected across a wide range of facilities. The pipeline calibrates the brightness of the comet to a common photometric system (Pan-STARRS 1) using background stars within the field allowing for compilation and comparison of multiple data sets. Results follow the predictions based on previous apparitions: 67P shows no obvious change in activity levels from orbit-to-orbit and coma colours remain constant throughout the apparition. We detected an outburst on 2015 August 22 of $sim$0.14 mag. The brightness and estimated mass of this outburst puts it in line with the outbursts directly observed on the nucleus by Rosetta. An in situ outburst was observed at the same time as the one seen from the ground, however linking these two events directly remains challenging. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.08915v1

Discovery of double BSS sequences in the old Galactic open cluster Berkeley 17 by Khushboo K Rao et al. on Monday 10 October Blue straggler stars (BSS) are peculiar objects which normally appear as a single broad sequence along the extension of the main sequence. Only four globular clusters (GCs) have been observed to have two distinct and parallel BSS sequences. For the first time for any open cluster (OC), we report double BSS sequences in Berkeley 17. Using the machine-learning based membership algorithm ML-MOC on Gaia EDR3 data, we identify 627 cluster members, including 21 BSS candidates out to 15 arcmin from the cluster center. Both the BSS sequences are almost equally populated and parallel to one another in Gaia as well as in Pan-STARRS colour-magnitude diagram (CMD). We statistically confirm their presence and report that both BSS sequences are highly segregated compared to the reference population out to $sim$5.5 arcmin and not segregated thereafter. The lower densities of OCs make BSS formation impossible via the collisional channel. Therefore, mass transfer seems to be the only viable channel for forming candidates of both sequences. The gap between the red and blue BSS sequences, on the other hand, is significant and presents a great opportunity to understand the connection between BSS formation and internal as well as external dynamics of the parent clusters. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.02061v2

Using machine learning to investigate the populations of dusty evolved stars in various metallicities by Grigoris Maravelias et al. on Wednesday 14 September Mass loss is a key property to understand stellar evolution and in particular for low-metallicity environments. Our knowledge has improved dramatically over the last decades both for single and binary evolutionary models. However, episodic mass loss although definitely present observationally, is not included in the models, while its role is currently undetermined. A major hindrance is the lack of large enough samples of classified stars. We attempted to address this by applying an ensemble machine-learning approach using color indices (from IR/Spitzer and optical/Pan-STARRS photometry) as features and combining the probabilities from three different algorithms. We trained on M31 and M33 sources with known spectral classification, which we grouped into Blue/Yellow/Red/B[e] Supergiants, Luminous Blue Variables, classical Wolf-Rayet and background galaxies/AGNs. We then applied the classifier to about one million Spitzer point sources from 25 nearby galaxies, spanning a range of metallicites ($1/15$ to $sim3~Z_{odot}$). Equipped with spectral classifications we investigated the occurrence of these populations with metallicity. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.06303v1

A machine-learning photometric classifier for massive stars in nearby galaxies I The method by Grigoris Maravelias et al. on Wednesday 14 September (abridged) Mass loss is a key parameter in the evolution of massive stars, with discrepancies between theory and observations and with unknown importance of the episodic mass loss. To address this we need increased numbers of classified sources stars spanning a range of metallicity environments. We aim to remedy the situation by applying machine learning techniques to recently available extensive photometric catalogs. We used IR/Spitzer and optical/Pan-STARRS, with Gaia astrometric information, to compile a large catalog of known massive stars in M31 and M33, which were grouped in Blue, Red, Yellow, B[e] supergiants, Luminous Blue Variables, Wolf-Rayet, and background galaxies. Due to the high imbalance, we implemented synthetic data generation to populate the underrepresented classes and improve separation by undersampling the majority class. We built an ensemble classifier using color indices. The probabilities from Support Vector Classification, Random Forests, and Multi-layer Perceptron were combined for the final classification. The overall weighted balanced accuracy is ~83%, recovering Red supergiants at ~94%, Blue/Yellow/B[e] supergiants and background galaxies at ~50-80%, Wolf-Rayets at ~45%, and Luminous Blue Variables at ~30%, mainly due to their small sample sizes. The mixing of spectral types (no strict boundaries in their color indices) complicates the classification. Independent application to IC 1613, WLM, and Sextans A galaxies resulted in an overall lower accuracy of ~70%, attributed to metallicity and extinction effects. The missing data imputation was explored using simple replacement with mean values and an iterative imputor, which proved more capable. We also found that r-i and y-[3.6] were the most important features. Our method, although limited by the sampling of the feature space, is efficient in classifying sources with missing data and at lower metallicitites. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2203.08125v2

The 2019 Discovery of a Meteor of Interstellar Origin

The 2019 Discovery of a Meteor of Interstellar Origin by Amir Siraj et al. on Thursday 01 September The earliest confirmed interstellar object, `Oumuamua, was discovered in the Solar System by Pan-STARRS in 2017, allowing for a calibration of the abundance of interstellar objects of its size $sim 100;$ m. This was followed by the discovery of Borisov, which allowed for a similar calibration of its size $sim 0.4 - 1 mathrm{; km}$. One would expect a much higher abundance of significantly smaller interstellar objects, with some of them colliding with Earth frequently enough to be noticeable. Based on the CNEOS catalog of bolide events, we identify the $sim 0.45$m meteor detected at 2014-01-08 17:05:34 UTC as originating from an unbound hyperbolic orbit with 99.999% confidence. The U.S. Department of Defense has since verified that "the velocity estimate reported to NASA is sufficiently accurate to indicate an interstellar trajectory." We infer that the meteor had an asymptotic speed of $v_{infty} sim 42.1 pm 5.5; mathrm{km ; s^{-1}}$ outside of the solar system. Its origin is approximately towards R.A. $49.4 pm 4.1^{circ}$ and declination $11.2 pm 1.8^{circ}$, implying that its initial velocity vector was $58pm6; mathrm{km;s^{-1}}$ away from the velocity of the Local Standard of Rest (LSR). Its high LSR speed implies a possible origin from the deep interior of a planetary system or a star in the thick disk of the Milky Way galaxy. The local number density of its population is $10^{6{^{+0.75}_{-1.5}}} ; mathrm{AU^{-3}}$ or $9 times 10^{21{^{+0.75}_{-1.5}}} ; mathrm{pc^{-3}}$ (necessitating 0.2 -- 20 Earth masses of material to be ejected per local star). We show that the detections of CNEOS 2014-01-08, `Oumuamua, and Borisov collectively imply that the differential size distribution in good agreement with a collisional distribution, with a power-law slope is $q sim 3.6 pm 0.5$, where the quoted uncertainty corresponds to $2 sigma$. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/1904.07224v5

Scooping Interstellar Fragments from the Ocean FloorAlbert Einstein famously argued in a letter to the physicist Max Born in December 1926 that God does not play dice. The letter referred to the probabilistic nature of Quantum Mechanics but it can also be interpreted more broadly as if nature does not make random choices. In fact, it is the duty of a scientist to make sense of nature's choices. Otherwise, reality looks random to those who do not understand it. Weather was perceived this way before satellite and ground-based data allowed modern science to make weather forecasts a week in advance. The fundamental insight we learned as an advanced scientific civilization is that we should be guided by evidence rather than prejudice. The range of possibilities, as often imagined in mathematics or science fiction stories, is far greater and sometimes has no overlap with what is actually realized in nature.On April 6, 2022, the United States Space Command tweeted a formal letter confirming that a meteor identified in the CNEOS catalog by my student Amir Siraj and me in 2019 as originating from outside the Solar system based on its high speed, is indeed interstellar. The meteor detection on January 8, 2014 predated the first reported interstellar object, `Oumuamua, by almost four years and should be recognized as the first interstellar object ever discovered. The meteor paper was initially doubted because the uncertainties in the velocity measurements were classified. The release of the confirmation letter is a watershed moment in which the government assists scientific progress by confirming the interstellar origin of this so-called CNEOS-2014–01–08 meteor at the 99.999% confidence.Our discovery of an interstellar meteor heralds a new research frontier, in which the Earth serves as a fishing net for massive interstellar objects. As a result of encountering Earth and rubbing against its atmosphere, an interstellar object burns up in a bright fireball. This fireball is detectable by satellites or ground-based sensors even for relatively small interstellar objects like CNEOS-2014–01–08, which was about a meter in size and created a fireball carrying a percent of the energy of the Hiroshima bomb. This size scale is a hundred times smaller than `Oumuamua, which was discovered by the Pan STARRS telescope through its reflection of sunlight. This alternative detection method allows existing survey telescopes to discover only objects larger than a football field, within the orbit of the Earth around the Sun.There should be a million objects as small as CNEOS-2014–01–08 within that volume for every `Oumuamua-size object, but only a tiny fraction of them is seen as meteors because of the small size of our “fishing net”, the Earth. The situation is analogous to finding many more small fish than whales in the ocean. But we should also keep in mind that most meteors originate from the Solar system, but the interstellar ones can be flagged by their high speeds.The interstellar meteor discovery is very important from another perspective. One can imagine a billion dollar mission to land on an interstellar object like `Oumuamua and return a sample of it to Earth, similar to the OSIRIS-REx mission that landed on the asteroid Bennu and will return material from it in September 2023. But at a cost that is ten thousand times smaller, one could scoop fragments left over from an interstellar meteor and study them in our laboratories.The debris from CNEOS-2014–01–08 landed on the ocean floor near Papua New Guinea and it is possible to scoop them with a magnet. Once collected, we could place our hands around sizeable chunks of interstellar matter and examine its composition and nature. The ocean on site is a couple of kilometers deep and the impact region is uncertain to within ten kilometers. But an expedition to explore this region for meteor fragments is feasible and we are currently engaged in designing it.The fundamental question is whether any interstellar meteor might indicate a composition that is unambiguously artificial in origin? Better still, perhaps some technological components would survive the impact. My dream is to press some buttons on a functional piece of equipment which was manufactured outside of Earth.This gives a whole new meaning to a “fishing expedition”; in this case, of extraterrestrial equipment.In February 1954, just 14 months before he died, Einstein wrote a letter to the physicist David Bohm, in which he stated: “If God created the world, his primary concern was certainly not to make its understanding easy for us.” I wonder whether our expedition to Papua New Guinea might replace the word `God' in Einstein's statements by the term `an advanced scientific civilization'.ABOUT THE AUTHORAvi Loeb is the head of the Galileo Project, founding director of Harvard University's — Black Hole Initiative, director of the Institute for Theory and Computation at the Harvard-Smithsonian Center for Astrophysics, and the former chair of the astronomy department at Harvard University (2011–2020).

Den 6. november 2018 sendte NTB ut denne meldingen: Et sigarformet objekt som i fjor ble observert i vårt solsystem, kan ha vært et utenomjordisk romskip sendt for å observere jorda, mener Harvard-forskere. Objektet fikk kallenavnet «Oumuamua», som betyr «en budbringer fra en fjern fortid» på hawaiisk. Objektet ble først observert i oktober i fjor av teleskopet Pan-STARRS 1 på Hawaii. Tucker Carlson har vært opptatt av UFO-besøk i lang tid og viet ekstra oppmerksomhet til den mystiske gjenstanden som skled forbi solen og ble oppdaget ved en tilfeldighet. «Skipet» ble anslått å være 400 meter langt og det beveget seg med en hastighet på 315.000 km i timen. Vi har sett filmer som 2001 A Space Odyssey av Stanley Kubrick og Christopher Nolans Interstellar. Dette kan være the real thing. I en studie argumenterer forskere ved Harvard Smithsonian Center for Astrophysics for at det lange mørkerøde objektet, som er ti ganger lenger enn det er bredt og som ble observert med en hastighet på 315.400 kilometer i timen, kan være av «kunstig opprinnelse». – Oumuamua kan være en fullt fungerende sonde sendt med hensikt til jordas nærområder av en utenomjordisk sivilisasjon, skriver forskerne i studien, som er signert professor Abraham Loeb og Shmuel Bialy og sendt til Astrophysical Journal Letters for publisering. Forskernes teori er basert på objekts uventede økning i hastighet og bane da det reiste gjennom og til slutt ut av vårt solsystem i januar i år (2018). (NTB) Hva vil en interstellar budbringer eller speider? Hvis de kan reise så langt har de neppe problemer med å forstå vår kommunikasjon. Hva vil de? Pentagon vil de nærmeste dagene offentliggjøre hva deres kontor har samlet over flere år. Det kan virke som konklusjonen er uunngåelig: Vi er ikke alene i universet.

In 2017, the Pan-STARRS telescope in Hawaii spotted an interstellar object passing by Earth for the first time. Shortly after, Harvard’s Prof Avi Loeb was met with a backlash from the scientific community for suggesting it could be of alien origin.Now, several years on, he has written a book, Extraterrestrial: The First Sign of Intelligent Life Beyond Earth, outlining why we still can’t out rule the possibility, and why scientists should always keep an open mind.We speak to Avi on this week's episode of the Science Focus Podcast. He tells us why he believes the object, 'Oumuamua, was of alien origin, and what problems this reveals about the way modern physics is conducted.Read an edited excerpt of this interviewLet us know what you think of the episode with a review or a comment wherever you listen to your podcasts.Subscribe to the Science Focus Podcast on these services: Acast, iTunes, Stitcher, RSS, OvercastRead the full transcription of this episode [this will open in a new window]Listen to more episodes of the Science Focus Podcast:Dr Douglas Vakoch: Should we try to contact aliens?Bergur Finnbogason: Project Discovery and its search for exoplanetsDr Erin Macdonald: Is there science in Star Trek?What if the Earth’s magnetic field died? – Jim Al-KhaliliBuilding a base on the Moon, and crafting believable sci-fi – Andy WeirDr Becky Smethurst: How do you actually find a black hole?

On October 19th, 2017 Robert Weryk turned to a new part of the sky with the Pan-STARRS telescope at Haleakalā Observatory in Hawaii and spotted something that would earn him international acclaim and leave physicists and astronomers scratching their heads for years. Scientists have long pondered the possibility of Interstellar Travel. Even though, Weryk might not be the first astronomer to discover how to travel outside our solar system he just might be the first astronomer to discover evidence of Interstellar Travel. No, it's not Aliens. Well, actually, it might be Aliens. Whatever it is, scientists have finally settled on the name 'Oumuamua which is Hawaiian for scout. The name alone tells us they know what we hope it is, Aliens.

En 2017 se produjo la detección de un cuerpo en nuestro sistema solar que se movía a gran velocidad. El artífice del descubrimiento fue el Telescopio de Sondeo Panorámico y Sistema de Respuesta Rápida (Pan-STARRS), de la Universidad de Hawái. Entonces se bautizó con el nombre de Oumuamua. A partir de entonces se han desatado toda suerte de especulaciones por parte de los científicos. ¿Es un cometa, un asteroide o una nave extraterrestre? Esta noche conoceremos todas las novedades en torno a este enigma y entrevistaremos a Abraham Loeb, director del Departamento de Astronomía de la Universidad de Harvard (EE.UU.), que defiende que este objeto interestelar no puede ser ni un cometa ni un asteroide, inclinándose por la tecnología de origen extraterrestre.

The next generation of surveys, e.g. the Dark Energy Survey, PanSTARRS, LSST, Euclid and others, aim to study the nature of Dark Energy and alternatives. The talk will discuss how the Dark Energy paradigm evolved over the past 20 years, and the cosmic probes which will help us to test it. In particular the surveys rely on accurate of photometric redshifts for the determination of cosmological quantities such as Dark Energy parameters and neutrino masses. The talk will describe photometric redshift methods and their impact on analysing galaxy clustering and weak lensing data and on the derived cosmological parameters.

For this reason a baseball pitcher tries to have a long pull on the ball before releasing it.Astronomers have a theory, called the Yorp effect, that light from the Sun produces a very tiny torque which increases the rate of spin of an object. The effect is so small that it would take billions of years to be produce a measurable outcome. How can such an idea ever be tested?In September of 2013, the Pan-STARRS group found a strange moving object in the night sky. The plot thickened when the Keck Telescope on Mauna Kea Hawaii found that instead of being a single body it appeared to be three small objects embedded in a cloud of gas and dust several thousands of miles in diameter. The Hubble Space Telescope was used to see what is going on.Hubble found that this object changes significantly over a period of months, that it has 6 tails, and that pieces of it continue to emerge from the center and slowly move away at a walking pace.An asteroid collision is too violent to cause what is seen. The object is too cold for expanding gases to cause it to break up. The best explanation which fits the data is that Sun light has slowly, over billions of years, increased P/2013 P5's rate of spin causing it to gently come apart. Some of the dust and small particles which escape from it will orbit the Sun.

They happened to land in a gravitational dip which has allowed them to remain relatively undisturbed for billions of years.The asteroid Hektor orbits the Sun at a point where the gravity of the Sun and Jupiter create a stable point 60 degrees in front of the giant planet. In 1907 Hector was discovered as a moving point of light in the night sky. For the next 99 years its true nature remained unknown. In the past few years the Keck Telescope in Hawaii has discovered that the main body is a 230 mile long peanut shaped object. Most recently Keck was used to discover that Hektor has a 7.5 mile diameter moon which has a dense core surrounded by icy layers. This asteroid moon orbits the peanut shaped Hektor in a stable orbit every 3 hours.Recently, NASA scientists using the Goldstone Radar telescope were taking advantage of a close approach of a potentially hazardous asteroid to obtain radar images. These data show 2006 DP14 is a peanut shaped object about 1300 feet long. It slowly spins with a 6 hour period. Previous data from Goldstone and the Arecibo Observatory in Puerto Rico suggests that more than 10 % of near Earth asteroids larger than 650 feet in diameter have a peanut shape.

Fortunately none of them were on a collision course with Planet Earth.Interest in smaller space rocks has increased since a semitrailer truck sized asteroid entered the Earth's atmosphere over Russia in February of 2013. Most of the nearly 1500 injuries could have been avoided if people in the impact area had been warned to stay away from windows.In January of 2014 a refrigerator sized asteroid was discovered about 20 hours before it exploded over the Atlantic Ocean off the coast of Africa. It is estimated that there are a billion near Earth Asteroids of similar size.It is likely that we have discovered 90% of the approximately one thousand near Earth asteroids whose impact would cause global climate change. There are probably 300,000 smaller Earth approaching asteroids whose impact would devastate thousands of square miles of the Earth's surface. So far we have discovered about 5,000 of them.

After becoming gravitationally-trapped, the four potentially interstellar objects — 2011 SP25, 2017 RR2, 2017 SV13, and 2018 TL6 — are thought to spend most of their time between the orbits of Jupiter and Neptune. In a paper submitted to the Monthly Notices of the Royal Astronomical Society, Harvard co-authors Amir Siraj and Abraham Loeb, compare the orbital characteristics of theoretical high-inclination objects to those of the centaurs, the most similar population of known asteroids. “We find that there should be hundreds of Oumuamua-size interstellar objects identifiable by Centaur-like orbits,” write the authors. 1I/2017 U1 Oumuamua, the first bona fide interstellar object, was discovered Oct. 19, 2017 by the University of Hawaii's Pan-Starrs telescope. But the authors note that there should be at least 66 possible other interstellar objects in their calculations, ranging in diameter from roughly 100 meters to 10 kilometers in size. And all of these potential interstellar interlopers should be detectable by the LSST (Large Synoptic Survey Telescope), currently under construction in Chile. “ We do not know if they are comets, asteroids, or artifacts ,” Amir Siraj, a Harvard University undergraduate in astrophysics, told me They pass near Earth on timescales of some 20 to 120 years so it will be another 20 years until we can photograph one of them, he says.

After becoming gravitationally-trapped, the four potentially interstellar objects — 2011 SP25, 2017 RR2, 2017 SV13, and 2018 TL6 — are thought to spend most of their time between the orbits of Jupiter and Neptune. In a paper submitted to the Monthly Notices of the Royal Astronomical Society, Harvard co-authors Amir Siraj and Abraham Loeb, compare the orbital characteristics of theoretical high-inclination objects to those of the centaurs, the most similar population of known asteroids. “We find that there should be hundreds of Oumuamua-size interstellar objects identifiable by Centaur-like orbits,” write the authors. 1I/2017 U1 Oumuamua, the first bona fide interstellar object, was discovered Oct. 19, 2017 by the University of Hawaii's Pan-Starrs telescope. But the authors note that there should be at least 66 possible other interstellar objects in their calculations, ranging in diameter from roughly 100 meters to 10 kilometers in size. And all of these potential interstellar interlopers should be detectable by the LSST (Large Synoptic Survey Telescope), currently under construction in Chile. “ We do not know if they are comets, asteroids, or artifacts ,” Amir Siraj, a Harvard University undergraduate in astrophysics, told me They pass near Earth on timescales of some 20 to 120 years so it will be another 20 years until we can photograph one of them, he says.

Ulkoavaruuden hiippari Oumuamua hämmentää - oliko kyseessä komeetta vai vieraan sivilisaation avaruusalus?

Tiedeykkönen

Aurinkokunnassamme vieraillut outo avaruuskappale Oumuamua on noussut jälleen otsikoihin. Harvardin yliopiston tutkijat, professori Abraham, Avi Loeb ja tutkijatohtori Shmuel Bialy kohahduttivat julkistamalla vastikään tutkimuksen, jossa he ehdottavat että kyse saattoi olla vieraan sivilisaation avaruusaluksesta. He ovat tehneet päättelynsä laskelmista, jotka on julkaistu arXivissa ja Astrophysical Journal Lettersissä. Päätelmä on kohahduttanut tutkijayhteisöä kautta maapallon. Useimmat heistä ovat tätä päätelmää vastaan, koska kyseisen kappaleen outo liikehdintä voidaan selittää myös luonnollisen kappaleen liikkeenä. Tiedeykkösessä pohditaan Oumuamuan mahdollista rakennetta ja liikkeitä aurinkokunnassa. Haastateltavana on Mikael Granvik, joka on Luulajan teknillisen yliopiston professori ja akatemiatutkija Helsingin yliopistossa. Mikael Granvikin mukaan tällaisia ulkoavaruuden kappaleita havaitaan tulevina vuosina yhä enemmän koska käytettävissä on entistäkin parempia havaintolaitteita. Mikael Granvikia haastattelee Sisko Loikkanen. PanStarrs -teleskooppi Havaijilla havaitsi Oumuamuan lokakuussa 2017. Sille annettiin havaijinkielinen nimi Oumuamua, joka tarkoittaa kaukaa avaruudesta tullutta vierasta. Oumuamua on ensimmäinen havainto ulkoavaruudesta aurinkuntaamme tulleesta kappaleesta.

Fue descubierto por el telescopio Pan-Starrs de Hawai, y en las imágenes de radar, una de sus caras aparecía como una terrorífica calavera. Eso hizo que enseguida adquiriese notoriedad, y que recibiera distintos apodos. Este oscuro asteroide tiene unos 650 metros de diámetro, su periodo de rotación ronda las cinco horas, tarda 3,04 años en completar su órbita y refleja aproximadamente un 6 % de la luz que recibe del Sol, prácticamente igual que la luna, mientras que la Tierra refleja más del 37 % Por su tipo de órbita, 2015 TB145, perdón… el asteroide Halloween, se considera un asteroide tipo Apolo, aunque los astrónomos piensan que en realidad puede ser un antiguo cometa que perdió sus compuestos volátiles tras múltiples pasos alrededor del Sol. En general, los asteroides son más rocosos y metálicos mientras que los cometas presentan una mayor proporción de hielo con algo de roca. Ambos tipos de objetos se formaron hace unos 4.600 millones de años, cuando nació nuestro sistema solar y han sido testigos de su evolución… como si fueran fantasmas que observan desde las sombras del universo.

Oumuamua is the first known interstellar object to pass through the Solar System. Formally designated 1I/2017 U1, it was discovered by Robert Weryk using the Pan-STARRS telescope at Haleakala Observatory, Hawaii, on 19 October 2017, 40 days after it passed its closest point to the Sun. When first seen, it was about 33,000,000 km from Earth (about 85 times as far away as the Moon), and already heading away from the Sun.

UFO author Stanley Romanek sentenced to 2 years to halfway house for child pornography possession Article link: http://www.coloradoan.com/story/news/2017/12/14/ufo-author-stanley-romanek-sentenced-2-years-halfway-house-child-pornography-possession/952799001/ Four months after his conviction for possession of child pornography, Romanek was sentenced to two years in Larimer County community corrections, a halfway house program for criminal offenders. Friends and family of the 55-year-old Loveland UFO author who says he is an alien abductee spoke of a man who was selfless and caring and would not hurt anyone. Prosecutors described the lengths of deception and denial he took to avoid a guilty verdict and blame anyone but himself. Blanco acknowledged Romanek's and his supporters' statements and said she had no doubt that he had some good in him. But still, considering the materials found on his computer over a period of time, along with the continued denial and deception, "there's a good argument for you to go to prison." She reminded Romanek that there was no longer a presumption of his innocence. But she said there may be some hope for rehabilitation, and therefore, he would be sentenced to Community Corrections based on recommendations from multiple professionals. Stephen Hawking wary of mysterious flying object, says it may be ‘interstellar spacecraft' Article link: https://technology.inquirer.net/70419/stephen-hawking-wary-of-mysterious-flying-object-says-it-may-be-interstellar-spacecraft This artist's impression shows the first interstellar asteroid: Oumuamua. This unique object was discovered on Oct. 19, 2017, by the Pan-STARRS 1 telescope in Hawaii In October, scientists discovered a massive, cylindrical object visiting our solar system, which has been dubbed “Oumuamua,” a Hawaiian term that means “a messenger from afar arriving first.” The unidentified flying object has become the subject of fascination among astrophysicists—primarily for its dubious origin. “Researchers working on long-distance space transportation have previously suggested that a cigar or needle shape is the most likely architecture for an interstellar spacecraft, since this would minimise friction and damage from interstellar gas and dust,” he was quoted as saying in a report from the Daily Star. “While a natural origin is more likely, there is currently no consensus on what that origin might have been, and Breakthrough Listen is well positioned to explore the possibility that Oumuamua could be an artefact,” he added. Hawking's findings, meanwhile, comes from a scientific body called Breakthrough Listen, a £74-million (P5.02-billion) search for intelligent alien life, which uses the world's largest maneuverable radio telescope. The project is based in Green Bank in West Virginia, USA, and is currently focused on tracking Oumuamua's movement.
