Astronomers using the MeerKAT radio telescope found a new population of horizontal, 5–10 light-year filaments near the Galactic Center that point toward Sagittarius A*. Their thermal emissions and alignment along the galactic plane differ from previously known vertical filaments, suggesting a past energetic outflow from the Milky Way’s central black hole and offering clues about its accretion disk orientation and history.
Astronomers using the Atacama Large Millimeter/submillimeter Array released the largest, most detailed image of the Milky Way's center, revealing long gas filaments feeding star formation and offering a connected view of our galaxy’s core that will be explored further with JWST and the ELT, though telescope time remains highly oversubscribed.
A Curtin University study published in Forensic Chemistry shows that infrared spectroscopy of 3D-printing filaments can distinguish many filament types and link seized ghost guns to their source, challenging the notion that ghost guns are truly untraceable; however, some filaments remain indistinguishable, and researchers plan to add more analytical techniques to strengthen traceability.
Astronomers using FAST have discovered a highly complex, supersonic network of tangled filaments in the gas cloud G165, revealing that turbulence and magnetic fields, rather than gravity, shape early interstellar cloud structures, offering new insights into galactic evolution.
Astronomers have captured the first direct image of a filament in the cosmic web, revealing gas flowing between two ancient quasars over 11 billion light-years away, confirming theories about how galaxies grow by siphoning gas along web-like structures and providing new insights into dark matter and galaxy formation.
Astronomers using ESA's XMM-Newton and JAXA's Suzaku telescopes have discovered a massive filament of hot gas, bridging four galaxy clusters and potentially explaining some of the universe's missing baryonic matter, aligning with cosmological models and shedding light on the cosmic web's structure.
Astrophysicists have discovered one-dimensional filaments between 5-10 light-years in length in the Milky Way, thought to be outflows from Sagittarius A, a supermassive black hole at the center of the galaxy. These filaments are exceptionally long strings of electrons interacting with a magnetic field and only appear on one side of Sag A, pointing radially toward the black hole. The discovery was made possible by enhanced radio astronomy technology, specifically the South African Radio Astronomy Observatory’s MeerKAT telescope. The filaments could help scientists learn more about the way Sag A spins and its orientation relative to the rest of the Milky Way.
New filaments have been discovered near the Milky Way's supermassive black hole, Sagittarius A*. These filaments are shorter and lie horizontally, pointing directly to Sagittarius A*. They are related to the activity of Sagittarius A*, but it is unclear if the two types of filaments are related. The vertical filaments are magnetic accelerating particles close to the speed of light, while the horizontal ones appear to emit heat, accelerating thermal material in a molecular cloud. The newly discovered filaments are estimated to be about 6 million years old and may have originated from an outflow from an activity that happened a few million years ago.
An international team of astrophysicists has discovered hundreds of mysterious structures in the center of the Milky Way galaxy. These one-dimensional cosmic threads are hundreds of horizontal or radial filaments, slender, elongated bodies of luminous gas that potentially originated a few million years ago when outflow from Sagittarius A*, the Milky Way’s central supermassive black hole, interacted with surrounding materials. The researchers found the structures by analyzing images produced by the South African Radio Astronomy Observatory’s MeerKAT telescope.

An international team of astrophysicists has discovered a new population of threads at the center of the Milky Way, which differ from their vertical counterparts, being significantly shorter and arranged horizontally or radially, resembling spokes radiating outward from the black hole, like Morse code's dots and dashes. While the vertical filaments sweep across the galaxy, towering as high as 150 light-years, the horizontal filaments punctuate only one side of Sagittarius A* and exhibit a pattern akin to Morse code.
Astronomers have discovered hundreds of mysterious filaments pointing towards the Milky Way's supermassive black hole, Sagittarius A*. The filaments, which are less than 10 light years in length, are estimated to be about six million years old and appear to be tied to activities in the galactic center. The discovery was made possible by the South African Radio Astronomy Observatory's MeerKAT telescope. The filaments could provide insights into the black hole's spin and accretion disk orientation.
Astronomers have discovered hundreds of previously unknown "filaments" at the center of the Milky Way, each measuring between 5 and 10 light-years in length and visible only in radio wavelengths. These structures appear to point directly at the central supermassive black hole, Sagittarius A*, suggesting that they may be the unhealed scars of an ancient, high-energy black hole outburst that tore through the surrounding clouds of gas. The filaments were likely created by bursts of high-energy particles that are invisible to the naked eye, and may have been caused by an eruption of energy from the black hole around 6 million years ago.
Astrophysicists have discovered a new group of horizontal filaments radiating from the supermassive black hole at the center of the Milky Way, which could provide more insights into the black hole’s spin and accretion disk orientation. The filaments, each measuring 5 to 10 light-years in length, likely originated a few million years ago when outflow from the black hole interacted with surrounding materials. The discovery builds on four decades of research and was made possible by enhanced radio astronomy technology, particularly the MeerKAT telescope.
