SANDY, Utah--(BUSINESS WIRE)--Jun 2, 2023--

Scientists have found an array of “dashes” within our universe, all arranged in an unexpected pattern. The vast structures are lying in the middle of our Milky Way galaxy and point towards the black hole at its core. There are hundreds of them, each five to 10 light-years long, researchers say. “It was a surprise to suddenly find a new population of structures that seem to be pointing in the direction of the black hole,” Northwestern University’s Farhad Yusef-Zadeh, who led the research. “I was actually stunned when I saw these. We had to do a lot of work to establish that we weren’t fooling ourselves. And we found that these filaments are not random but appear to be tied to the outflow of our black hole. By studying them, we could learn more about the black hole’s spin and accretion disk orientation. It is satisfying when one finds order in a middle of a chaotic field of the nucleus of our galaxy.” Scientists have no confirmed explanation for where the structures came from, and much about their existence remains a mystery. But one possible explanation is that they were thrown out from after some activity a few million years ago. In the early 1980s, Professor Yusef-Zadeh found a set of gigantic, one-dimensional filaments hanging across our galaxy, near Sagittarius A*, the black hole at the heart of the Milky Way. The new filaments were previously undiscovered, and are much shorter and lie across, spreading out from the black hole. “We have always been thinking about vertical filaments and their origin,” he said. “I’m used to them being vertical. I never considered there might be others along the plane.” The research is described in a new paper, ‘The Population of the Galactic Center Filaments: Position Angle Distribution Reveal a Degree-scale Collimated Outflow from Sgr A* along the Galactic Plane’, published in The Astrophysical Journal Letters.

Scientists have been left baffled by the discovery of the wreck of a 2,000-year-old “computer” that is amazingly complex. The Antikythera mechanism – an astronomical calendar – has been dubbed “‘the first computer” and has baffled scientists for generations after it was first discovered inside a Greek shipwreck in 1901. The device is a hand-powered time-keeping instrument that used a wing-up system to track the sun, moon and planets’ celestial time. It also worked as a calendar, tracking the phases of the Moon and the timing of eclipses. Despite sounding relatively simple, the mechanism was actually ahead of its time, being more technically sophisticated than any other tool that was invented over the next 1,000 years. In its current condition, the mechanism is in 82 separate fragments with only a third of its original structure remaining, including 30 corroded bronze gearwheels. Sign up to our free Indy100 weekly newsletter Research into the device from experts at University College London involved 3D computer modelling and helped them solve the mystery of how the device worked, revealing a “creation of genius”. Adam Wojcik, a materials scientist at UCL said at the time: “We believe that our reconstruction fits all the evidence that scientists have gleaned from the extant remains to date.” They theorised that the device tracked the movement of the sun, moon and planets on concentric rings, as the ancient Greeks believed that the sun and planets revolved around Earth, rather than the sun. The researchers explained in Scientific Reports: “Solving this complex 3D puzzle reveals a creation of genius—combining cycles from Babylonian astronomy, mathematics from Plato’s Academy and ancient Greek astronomical theories.” Have your say in our news democracy.
