Black hole near Earth: What will Happen According to Scientists We have said it many times, but it is really worth repeating: the black hole is one of the most mysterious and at the same time disturbing celestial bodies that scientists have been able to observe in our skies. No wonder, then, that the presence of one of these enigmatic and impenetrable elements "lurking" in the universe has aroused not a little hype. What does "lurking"mean? Just what we imagine: the recently observed black hole is located in an area of space not too far from Earth and, until now, had gone unnoticed. Revealing its presence was the death of an unfortunate star, violently sucked by its gravitational field. The Mysterious Glow in the Sky and the Black Hole Hypothesis But what exactly happened? In essence, a group of astronomers, astrophysicists and researchers from UC Santa Cruz, the Niels Bohr Institute of the University of Copenhagen and theash As extraordinary as it may seem, in reality, this type of study is routine: in our sky, in fact, cosmic explosions and those stellar explosions are physiological. What the international team of scientists could not imagine, however, is that by means of observation with Pan-STARRS telescopes (which capture thousands of light curves per second) they would have captured a truly mysterious glow, which briefly eclipsed all the starlight of a dwarf galaxy "only" a million light years away from Earth. Scientists immediately agreed: only a celestial body could produce that kind of glow, and it was a black hole intent on "eating". The devoured star and the revealed black hole This has, at the moment, created a bit of panic. The scientists that conducted the survey, as seen from the ambitious Young Supernova Experiment, macrostudio on the energies transitional flock to the universe) have wondered how a black hole could actually be in that the dwarf galaxy and how is it possible that is escaped to the prior years. Before concluding that this arcane celestial body was present in that area of space, they therefore carried out a series of observations, also going backwards and comparing the images detected by the telescopes. There was no doubt: the images, basically, captured the passage of an unfortunate star that was orbiting in that area. At the exact moment when the star reached a specific point, the black hole revealed itself, dramatically attracting it to itself. He then ripped and devoured it, starting the so-called Tidal Disruption Event, which spaghettifies (yes, literally reduces it to spaghetti-like filaments) the star and causes a glow of electromagnetic radiation: just the glow spotted by scientists. What does the presence of the "lurking"black hole reveal to us? But what does the presence of this previously unnoticed black hole, which remained hidden for so long, reveal to us? According to the researchers, the answer is as simple as it is compelling and mysterious: that black holes have different shapes and sizes, ranging from the supermassive ones we "well" know to the tiny ones, passing through intermediate sizes. According to researchers at UC Santa Cruz, the Niels Bohr Institute at the University of Copenhagen and the Ashington State University, in particular, the "lurking" black hole would be of intermediate size. "If we can analyze the population of intermediate-mass black holes in the universe-said one of the team's scientists, Enrico Ramirez – Ruiz-by understanding how many there are and where they are, we can finally understand if our theories of supermassive black hole formation are correct and we can refine the classic" black hole hunting"techniques, which may be more deficient than we imagine.

NASA selects potatoes to grow (perhaps) on Mars One hundred varieties of tubers growing in the Andes will be grown in a laboratory simulating the Martian atmosphere. Those who pass the test could end up on the Red Planet.

It is almost a ritual, which is repeated every year. It is one of the rare occasions to observe a celestial phenomenon with the naked eye; sometimes obvious sometimes fleeting, if the sky is not covered or polluted by smog and lights and the timing of Return of the meteor dust swarms is right, the show will be suggestive. Poets, astronomers, aspiring astronauts, romantics. Space! Last Frontier, these are the shows aboard the Spaceship Earth !

Once again, a science fiction bestseller (almost) anticipated the future: in 1956, Philp K. Dick's minorit Report Report - which in 2002 became Spielberg's film of the same name starring Tom Cruise - imagined that, in a 2054ash IA serving the police. Now, in 2022, a team at the University of Chicago has created an artificial intelligence (AI) model that can predict the location of the next crime - and not criminals, as in the novel - , a week before it happens, with 90% accuracy: the algorithm, trained on data regarding violent crimes (such as murders or assaults) and against property (robberies of various types) that occurred between 2014 and 2016 in Chicago, has so far been tested in eight US cities. "We created a digital copy of an urban environment," explains Ishanu Chattopadha "If you feed AI with data of what happened in the past, it tells you what will happen in the future. The results of the study were published in Nature Human Behavior. Statistics and AI a combination that could, perhaps not too distant tomorrow, make life more difficult for the ill-intentioned. Useful for prevention, but let's not forget a good educational support for civil coexistence. This is intelligence, simple intelligence.

The Dart probe has started that in October 2022 will impact against an asteroid, in an attempt to divert it. This is a test to develop a strategy for any future emergencies. At 1 and 21 O'clock ( Atlantic coast of the United States) on November 24, 2021 NASA'S DART probe was launched from a Falcon 9 rocket to an asteroid, called Dydymos. The objective of the mission – which has made even treasure of the data acquired during the japanese mission Hayabusa 2 on Ryugu – will be to hit the moon of the asteroid, Dimorphos, impacting at a speed of 23.760 kilometers per hour. More generally, the mission wants to experiment with a strategy to deflect an asteroid that, in the future, was on a collision course with the Earth. The launch of DART took place as planned: the probe now flies free to its target, on which it will arrive on October 2, 2022. The impact will occur when the probe and asteroid are located just over 13 million kilometers from Earth.

Il progetto Asgardia e' talmente avanti... che quando mi volto indietro... vedo solo il futuro...

Hi everyone, i'm new to this community. Is there a Startup Incubator in Asgardia? Would you like to create one? Thank you

With a Crew Dragon spacecraft equipped with the largest porthole ever sent into space, SpaceX will once again be the first to inaugurate the true season of space tourism, with a first flight that will fund research activities on tumors. If we have so often said, "this is the first flight of the space tourists", there is, however, always been at least a new, large or small, has made us think again: we don't want food controversies between space company, but to SpaceX at the time scheduled for September 25, has all the numbers to truly be a pleasure trip, a tourist, in fact. Flight Inspiration4 (I4) will not go to the Space Station (as the first space tourists did, from Dennis Tito onwards), but will reach Earth orbit and stay there for about four days, floating in space (as Virgin Galactic and Blue Origin flights did not): the crew will be entirely composed of tourists, from the pilot to the passengers. They will depart from the Kennedy Space Center Launch Complex 23 aboard The Crew Dragon Resilience spacecraft, launched by a Falcon 9. Fundraising. The crew is composed of civilians, women and men who are space beginners, that is, who have never had experience of spaceflight - in short, it is an entirely private flight. The objective is to raise funds (millions of dollars) for the research and treatment of cancer - in particular, those pediatric - St. Jude Children's Research Hospital, Memphis (Tennessee, USA), whose operating costs are of the order of us $ 2.8 million a day, but nothing is charged to the patients. In the intentions of the crew it is therefore a flight full of symbols that have been carved on them, designed to encourage humanity to take ever better roads. Crew. Jared Isaacman embodies the leadership; founder and ceo of Shift4Payment (platform for digital payments), you will be the commander of the I4: founded his company at the age of 16 years, at 21, he obtained the licence of the pilot and then became a pilot of commercial and military aircraft, collecting several records in the world (from the performances in the air-on the show, around the world in a jet in a little less than 62 hours); on the 12th of August, he announced that the edge of the Resilience there will be 32 kg of hops that, back to the Ground, will be auctioned off to finance the projects of the St Jude. The hope is the story of Hayley Arceneaux, 29 years old, assistant physician to St. Jude Children's Research Hospital, a medical officer aboard the I4: born in Louisiana (USA), at the age of 10 years, was diagnosed with osteosarcoma (bone cancer); successfully treated at St. Jude, he is now working in the same hospital with patients suffering from leukemia and lymphoma - will now become the youngest american to reach orbit. For the prosperity, there is Sian Proctor, pilot of the mission: born in Hagåtña (Guam, USA), geoscienziata, explorer and a specialist in scientific communication, Proctor is a professor of geology at the South Mountain Community College (Phoenix, Arizona), where he is also responsible for education aerospace for the Arizona Wing of the Civil Air Patrol. In the field for generosity will be Christopher Sembroski with the role of mission specialist: engineer and veteran of the US Air Force, consultant for Space Camp (program to bring children and young people closer to space and science), works as an engineer at Lockheed Martin. Training. The crew underwent a relatively short, but very intensive training. Isaacman and Proctor have learned to control the spacecraft in the unlikely event that they are required to take control of it during the flight-which is expected to be fully controlled from the ground. During the training the four tourists aspiring astronauts familiarized themselves with the spacecraft and its emergency systems; they studied the launch operations of the previous missions, and the phases of ditching; they undertook zero-gravity flight training to familiarize themselves with the feeling of weightlessness and the immediate effects on the body. In mid-July they wore SpaceX spacesuits for the first time, and on August 9 and 10 they trained on decommissioned military jets to familiarize themselves with the gravitational forces to which they will be subjected to launch. Mission. For the Falcon 9 booked for the I4 will be the third flight, Resilience, officially the Crew Dragon C207, although modified, was that of the SpaceX Crew-1, the first mission of operation (after the mission demonstration of may 2020) that brought the astronauts of NASA and Jaxa on the space Station in November 2020 - may 2021): in particular, you removed the system docked to the ISS, and in its place was located a gigantic dome that will provide the crew with a view of the unprecedented of the Earth 360 degrees - it is the largest "window" never carried into space until now. The flight will not exceed 5 days, maximum time for which the spacecraft was built before having to dock for supplies: it has not yet been declared what will be done on board, but it will probably be a nice tourist flight, with very few tasks to perform except those of enjoying the view of land and space from a privileged position.

The future of mobiles and PCs? They invented an electrical circuit that uses droplets of liquid metal as conductors. And ensures flexibility, strength and recyclability.The technology of the most modern smartphones combined with the resistance of older phones: not a utopia, but a possible goal thanks to the invention of a flexible, resistant and recyclable electrical circuit. The team of researchers that conducted the study, the details of which have been published in Communications Materials, he is convinced that this discovery will pave the way for a new type of electronic devices that will be able to repair itself and reconfigure themselves, and can be fully recycled at the end of their life.Endless possibilities. Devices currently on the market, such as mobile phones or PCs, contain rigid cables and welded together, which stop working if they fail or are cut. The revolution of flexible circuits lies precisely in their resistance: even if punctured or damaged, they continue to function and transmit electricity. All this is possible thanks to the use of tiny drops of metal that pass inside an elastomer (a kind of "rubber") to be isolated. "To create circuits, we connect the metal drops together," explains Ravi Tutika, head of the studio. "We can then decide to separate them locally to rebuild new circuits, or even dissolve all the bonds and start from scratch by recycling the materials entirely."Indestructible. The circuits are flexible and continue to work even if they are extremely damaged: if they are pierced, instead of losing the connection totally, as in the case of traditional electrical cables, the droplets join around the hole formed and continue to transmit energy. The circuits can also stretch and continue to work: during the studies, the team managed to extend the device up to ten times its original length. "It's an exciting discovery, "says Michael Bartlett, one of the authors,"that projects us directly into a future of new flexible and sustainable technologies, more resilient and environmentally friendly."

A Japanese Transformer on the Moon The JAXA sends to the Moon a small robot transformer, quite similar to those of the famous comic. It will prepare the return of human astronauts. The robot of the JAXA: it splits into two hemispheres and changes shape as in a science fiction film. The robot of the JAXA: it splits into two hemispheres and changes shape as in a science fiction film. JAXA The next rover that will land on the Moon could be quite similar to the Transformer robots protagonists of the eponymous manga. JAXA, the Japanese space agency, has asked several companies and research bodies to make a small robot to be sent to our satellite to explore its surface and check the soil conditions. Objective of the mission: to collect data and information useful for the design of a future inhabited moon base. A very serious toy. The project involves researchers from Doshisa University, Sony Corporation and also Tomy Company, a toy manufacturer. The request of JAXA is to make the most of the technologies and to develop a robot that, at launch, is small and light. The agency asked its employees to work on a sphere of 8 centimeters in diameter and weighing not more than 250 grams. The result is the project of a spherical robot, which once landed on the Moon divides into two hemispheres joined together by an axis. The two halves thus become the wheels of the small rover that will have as its main objective to test the regolith, the very fine dust that covers the lunar soil, and gather useful information for the design of a larger rover, perhaps guided by a flesh-and-blood astronaut. The small transformer will collect soil samples, carry out analysis and take photographs: all the data will be transmitted to the lander (the shuttle dropped on the moon) that took it to the Moon and from here to Mission Control On Earth. JAXA and the Japanese government have made it clear several times that they do not want to be excluded from a hypothetical, future, international moon station. For this reason the project of the minilander is proceeding at a rapid pace and the space agency expects to send it to our satellite already by the end of 2022.
