Teleios: A mysterious sphere floating in the Milky Way
Teleios (Image source: Scientists are puzzled by the discovery of a perfectly spherical object floating in the Milky Way , which emits only radio signals. Named Teleios , this strange structure does not give off visible light, infrared glow, or detectable X-rays, only faint radio emissions. The discovery defies simple explanations and raises questions about how such a perfectly round object could exist in space. Teleios first drew attention when scientists observed a circular region emitting subtle radio waves, despite showing no signs of light or heat. The object was discovered by a team led by Professor Miroslav D. Filipović of Western Sydney University , using data from Australia's ASKAP (Australian Square Kilometre Array Pathfinder) telescope. Strange sphere, Teleios found in the Milky Way Although located within our galaxy, Teleios is completely invisible to the human eye. It lies thousands of trillions of miles from Earth, yet its radio signals traveled all the way to our telescopes. According to experts believe Teleios has a low surface brightness; its soft radio glow was detected during an all-sky survey carried out by ASKAP. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Esta nueva alarma con cámara es casi regalada en Rafael Castillo (ver precio) Verisure Undo Its remarkable symmetry is challenging scientists to reconsider common assumptions about space structures. Based on the radio data, scientists estimate Teleios could be up to 157 light-years in diameter. While some researchers believe it might be the remnant of a long-ago stellar explosion, its smooth, round shape has also led to speculation that it could be a young supernova remnant or a more mature structure. What scientists do agree on is that Teleios lies in a remote, quiet region of space, expanding silently and standing out due to its near-perfect symmetry. As one researcher noted, 'This unique object has never been seen at any wavelength, including visible light Is Teleios a supernova Some members of the research team suggest Teleios might be a massive bubble formed by stellar winds, but they can't rule out the possibility that it's an expanding cloud of gas and dust left behind after a star exploded. Teleios has only been detected in radio wavelengths, which are the longest waves in the electromagnetic spectrum. This highlights the important role of radio telescopes in spotting rare cosmic objects that would otherwise go unnoticed by human eyes or regular optical instruments. The debate continues. Some scientists believe a white dwarf may have caused the explosion, slowly gaining mass far from crowded star clusters. Others think Teleios may have exploded in a quiet, outer part of the Milky Way, where fewer stars and less gas allowed it to expand in a smooth, undisturbed way. One theory proposes that the star blew away surrounding material before it exploded, making the nearby space even emptier and allowing for its perfectly rounded shape. Unanswered questions about Teleios Scientists are planning follow-up observations to see if Teleios changes shape over time or remains spherical. Future studies using different wavelengths might help confirm whether stellar winds, debris, or a rare kind of stellar event shaped this symmetrical shell. Right now, no single piece of evidence gives a clear answer. Teleios remains a mystery, and each clue brings more questions. Even the presence or absence of faint remnants inside the sphere could challenge our current understanding of how stars live and die, or reveal rare cosmic conditions we've never seen before.

Scientists baffled by mystery sphere in space that could provide 'rare' universe insight
An incredible phenomenon in the depths of our galaxy has left scientists baffled. A perfectly spherical object, lying trillions of miles away from Earth but still in our Milky Way galaxy, has dumbfounded experts. Featuring 'remarkable circular symmetry', the sphere is defying space theories and going against the logic of what scientists thought they knew about the universe. Experts have named the sphere 'Teleios', which means 'complete' or 'perfect' in ancient Greek and refers to its perfect shape. It was first picked up by Australia's ASKAP telescope and is estimated to measure up to 157 light years wide. Estimate to be either 7,100 or 25,100 light years from Earth, the researchers' calculations are the equivalent of thousands of trillions of miles. The technology, named the Australian Square Kilometre Array Pathfinder (ASKAP), refers to an array of radio telescopes set in the country's Western Australia desert. Of the sphere, an international team of scientists said: 'The most obvious characteristic of Teleios is its remarkable circular symmetry, coupled with a low surface brightness.' Writing for The Conversation, they added: 'Teleios [is] named from the Greek Τελεɩοσ ('perfect') for its near-perfectly circular shape. 'This unique object has never been seen in any wavelength, including visible light, demonstrating ASKAP's incredible ability to discover new objects.' Researchers are not sure exactly what the sphere is composed of, but theories of what it might be include a 'supernova remnant', a term for debris left over after a supernova. That process is where a star explodes and launches debris and particles into space, which would mean the sphere could be made up of elements including carbon, oxygen, neon and silicon. The experts said: 'Remarkably, Teleios has retained its symmetrical shape as it aged even to such a diameter. 'The shape indicates Teleios has remained relatively untouched by its environment. This presents us with an opportunity to make inferences about the initial supernova explosion, providing rare insight into one of the most energetic events in the universe.' They said it could also be a stellar-wind bubble – a large cavity of gas launched by the upper atmosphere of a star. However, the scientists warned that the sphere needs more investigation before the sphere's nature can be confirmed. READ SOURCE

Scientists stumped by perfect sphere in Space sending out radio signals
A globe that looks like an alien world has been picked up by Australia's ASKAP telescope which has "remarkable circular symmetry" and defies current space theories A "perfect" sphere with 'low surface brightness' picked up by a radio telescope defies Space theories and has left scientists baffled. The floating globe that looks like an alien world was picked up by Australia 's ASKAP telescope hiding in our Milky Way trillions of miles away and is thought to be expanding. Invisible to the naked eye, what is really surprising is its shape. Scientists have named it Teleios, from the ancient Greek word for 'complete' or 'perfect' due to its 'remarkable circular symmetry' and they are so far at a loss to how it came to exist as it doesn't follow our current understanding of Space. The current size of Teleios is as big as possibly 157 light-years in diameter and can be made out in fuzzy blue and green images. What is also strange about the sphere is that it can only be seen in radio waves - the longest wavelengths in the electromagnetic spectrum. It means that scientists can't see it clearly as it can't be picked up through X-rays or for example infrared light. 'Teleios [is] named from the Greek Τελεɩοσ ('perfect') for its near-perfectly circular shape,' says the international team of researchers. 'The most obvious characteristic of Teleios is its remarkable circular symmetry, coupled with a low surface brightness.' The team led by astrophysicist Miroslav Filipovic at Western Sydney University in Australia added: 'This unique object has never been seen in any wavelength, including visible light, demonstrating ASKAP's incredible ability to discover new objects.' Teleios was spotted by the Australian Square Kilometre Array Pathfinder (ASKAP) which is a series of radio telescopes located in the desert in Western Australia. Although it is in our galaxy it is still thousands of trillions of miles away. While the scientists don't know what the sphere is, they do have theories including that it is a Type la supernova remnan'. A supernova occurs when a star explodes and throws debris into space - which also leads to it losing mass. A Type la supernova is one that doesn't destroy the white dwarf completely but leaves behind a zombie-like remnant and this would fit in with Teleios' properties, reported ScienceAlert. "We have made an exhaustive exploration of the possible evolutionary state of the supernova based on its surface brightness, apparent size and possible distances," said the scientists in their study. "All possible scenarios have their challenges, especially considering the lack of X-ray emission that is expected to be detectable given our evolutionary modelling. While we deem the Type Ia scenario the most likely, we note that no direct evidence is available to definitively confirm any scenario and new sensitive and high-resolution observations of this object are needed."

Scientists are BAFFLED after discovering a perfect sphere emitting radio signals from deep space
It looks like an alien world, or a floating snow globe suspended in space. At first glance it could even be a cue ball on a snooker table. But this perfect sphere, hiding in our Milky Way galaxy trillions of miles away, is leaving scientists baffled. The mysterious round object with 'remarkable circular symmetry' is defying current space theories, making its origin and nature unclear. Picked up by Australia's ASKAP telescope, researchers think it is probably expanding, although it is invisible to the naked eye. They have named it Teleios which comes from ancient Greek and means 'complete' or 'perfect' due to its stunning shape. Located in our galaxy, Teleios could be up to 157 light-years in diameter. 'The most obvious characteristic of Teleios is its remarkable circular symmetry, coupled with a low surface brightness,' say the international team of researchers. Teleios was discovered using the Australian Square Kilometre Array Pathfinder (ASKAP), an array of radio telescopes located in Western Australia's remote desert. It is either 7,100 or 25,100 light years away from Earth (2.2 or 7.7 kiloparsecs away), the researchers estimate – equating to thousands of trillions of miles. What's weird is Teleios is only visible in radio waves, which are the longest wavelength part of the electromagnetic spectrum. So Teleios can't be viewed in X-rays, infrared light or visible light, meaning we couldn't see it even if we were able to get close to it. 'Teleios [is] named from the Greek Τελεɩοσ ('perfect') for its near-perfectly circular shape,' the experts say in a piece for The Conversation. 'This unique object has never been seen in any wavelength, including visible light, demonstrating ASKAP's incredible ability to discover new objects.' While the academics don't know exactly what the space sphere is or how it formed, they do have a few solid theories. It could be a 'supernova remnant' – the debris left behind after a supernova, composed largely of elements such as carbon, oxygen, neon and silicon. A supernova occurs when a star spectacularly explodes, ejecting debris and particles into space, losing most of its mass in the process. Supernova remnants are composed largely of elements produced by nuclear fusion, such as carbon, oxygen, neon, and silicon. According to the team, who published their findings in arXiv, it also has a very low surface brightness for a supernova remnant. it could be either a young supernova remnant (under 1,000 years old) or a somewhat older supernova remnant (over 10,000 years old). But Teleios's 'exceptional circularity' is unusual for a supernova remnant, which may suggest that this classification may be not quite right. Supernova remnants are usually distorted, although if it had a region of space that's empty enough it could expand asymmetrically. 'Remarkably, Teleios has retained its symmetrical shape as it aged even to such a diameter,' they add. 'The shape indicates Teleios has remained relatively untouched by its environment. 'This presents us with an opportunity to make inferences about the initial supernova explosion, providing rare insight into one of the most energetic events in the universe. Another possibility is it could also be a stellar-wind bubble – an enormous cavity of gas ejected from the upper atmosphere of a star. The researchers caution that more study is needed on Teleios and other incredibly faint circular objects, which tend to show up with radio signals. 'No direct evidence is available to definitively confirm any scenario and new sensitive and high-resolution observations of this object are needed,' they conclude. The ASKAP telescope is undergoing one of its major observing programs called EMU (Evolutionary Map of the Universe). 'EMU is mapping the entire southern sky with an unprecedented sensitivity and will deliver the most detailed map of the southern hemisphere sky to date – a spectacular new radio atlas that will be used for decades to come,' they add. A supernova occurs when a star explodes, shooting debris and particles into space. A supernova burns for only a short period of time, but it can tell scientists a lot about how the universe began. One kind of supernova has shown scientists that we live in an expanding universe, one that is growing at an ever increasing rate. Scientists have also determined that supernovas play a key role in distributing elements throughout the universe. There are two known types of supernova. The first type occurs in binary star systems when one of the two stars, a carbon-oxygen white dwarf, steals matter from its companion star. Eventually, the white dwarf accumulates too much matter, causing the star to explode, resulting in a supernova. The second type of supernova occurs at the end of a single star's lifetime. As the star runs out of nuclear fuel, some of its mass flows into its core. Eventually, the core is so heavy it can't stand its own gravitational force and the core collapses, resulting in another giant explosion.

Astronomers Spot a Strangely Perfect Sphere Thousands of Light-Years Away
Here's what you'll learn in this story. Scientists using radio wavelength data from the Australian Square Kilometre Array Pathfinder (ASKAP) spotted a strangely symmetrical sphere located thousands of light-years away. The 'sphere' is likely the result of a Type 1a supernova shockwave, though astronomers aren't sure exactly how far away the this supernova remnant is from Earth—either 7,175 light-years or 25,114 light-years. Regardless of this distance discrepancy, the near-perfect spherical nature of the remnant gives scientists the opportunity to learn more about one of the most energetic events in the universe. The amount humanity has learned about the cosmos in just the past century is truly staggering. A little over a century ago, American astronomer Edwin Hubble announced to the world that the Milky Way was actually just one galaxy among many in the known universe. Now, we know the universe contains hundreds of billions—if not trillions—of galaxies, and engineers have developed space-based telescopes capable of spying some of the oldest ones in existence. Of course, that doesn't mean mysteries don't remain—both large and small. On the big side of the equation, dark matter and dark energy remain perplexing conundrums, but science's array of detectors often posit smaller puzzles. One such mystery is the curious case of supernova remnant (SNR) G305.4–2.2, nicknamed Teleios. A Greek word meaning 'perfect,' Telelios references the near-perfect symmetry of what appears to be a sphere of ejected star material—aka a supernova remnant. Initially captured by the Australian Square Kilometre Array Pathfinder (ASKAP), Teleios's origin isn't the real head-scratcher. Instead, scientists like Miroslav Filipović, an astrophysicist from Western Sydney University in Australia, are more perplexed by its near-perfect shape, an extreme rarity for such an SNR throughout the universe. 'The supernova remnant will be deformed by its environment over time,' Filipovic, along with a cadre of other Australian astrophysicists, wrote in an article on The Conversation in March. 'If one side of the explosion slams into an interstellar cloud, we'll see a squashed shape. So, a near-perfect circle in a messy universe is a special find.' In an analysis submitted to the Publications of the Astronomical Society of Australia and published on the preprint server arXiv, Filipović—the lead author of the study—and his team discovered that Teleios only glows faintly in radio wavelengths. Armed with this information, the astronomers could reasonably deduce that Telelios originated from a Type 1a supernova, which typically form from binary star systems where one of the stars is a white dwarf. Because these types of supernovae are consistent in their peak brightness, astronomers have used them for decades to measure cosmic distances (with none other than the Hubble telescope among others). However, in this instance, astronomers haven't been able to quite nail down Teleios's exact distance, but they've drawn up three best guesses. If it is the results of a Type 1a supernova, then its likely that this symmetrical mystery is either 7,175 light-years or 25,114 light-years away, making the sphere either 46 light-years across or 157 light-years across, respectively. This distance also reflects its age, meaning it's either less than 1,000 years old or greater than 10,000 years old. So, lots of room for further exploration. The study also posits the idea that it could be a Type 1ax supernova where the supernova instead leaves behind a 'zombie star' remnant, according to Live Science. However, in this scenario, the supernova would be only 3,262 light-years away and around 11 light-years across. Whatever the scenario, Teleios—which is just one of the many interesting things discovered by ASKAP—still presents a remarkable opportunity to learn more about supernovae. 'This presents us with an opportunity to make inferences about the initial supernova explosion, providing rare insight into one of the most energetic events in the universe,' Filipovic co-authors in The Conversation. In 100 years from now, who knows what the universe might look like to our 22nd-century enlightened minds.
