Astronomers localized FRB 20250316A (RBFLOAT), the brightest fast radio burst to date, to a region in the nearby spiral galaxy NGC 4141 using the CHIME/FRB Outrigger VLBI network. JWST follow-up detected a faint infrared signal at the same location. The burst did not repeat in hundreds of hours of CHIME data, challenging the idea that all FRBs are repeaters and offering new constraints on their origins.
An international team using China's FAST (Five-hundred-meter Aperture Spherical Radio Telescope) in Guizhou monitored the repeating FRB 20220529 and observed a sudden change in Faraday rotation, signaling interaction with dense plasma and supporting the idea that at least some fast radio bursts originate in binary systems; the bursts release energy equivalent to the Sun’s output over a week, marking a significant advance in understanding FRB origins.
Astronomers detected the brightest fast radio burst (FRB) ever, named RBFLOAT, from a galaxy 130 million light-years away, using advanced telescopes including CHIME and the James Webb Space Telescope. The observations suggest magnetars as a potential source and provide precise localization, helping to unravel the mystery of FRBs' origins and whether they repeat or vary in nature.
Scientists have successfully traced the brightest known fast radio burst, FRB 20250316A, to its origin in a galaxy 130 million light-years away using a network of telescopes, marking a significant milestone in understanding these mysterious cosmic flashes and suggesting magnetars as a possible source.
Astronomers detected the brightest fast radio burst (FRB) ever, called RBFLOAT, from a galaxy 130 million light-years away, using advanced telescopes including CHIME and Webb. This discovery helps pinpoint the burst's origin and supports the theory that magnetars could be the source, offering new insights into the nature and potential repetition of FRBs, which remain one of the universe's enduring mysteries.
Scientists have identified the origin of a powerful fast radio burst (FRB) from outer space, using the new CHIME Outrigger telescope, shedding light on these high-energy space signals that last only milliseconds but carry vital information about energetic cosmic phenomena.
Astronomers have identified the source of the brightest fast radio burst ever observed, named RBFLOAT, originating from a region in galaxy NGC 4141 about 130 million light-years away, using the CHIME telescope and JWST, which could shed light on the origins of these mysterious cosmic phenomena.
Astronomers using the MeerKAT telescope have discovered the most distant fast radio burst, FRB 20240304B, originating just 3 billion years after the Big Bang at a redshift of 2.148, providing new insights into the early universe and galaxy formation.
Scientists have traced a fast radio burst (FRB 20240304B) back to a galaxy just 3 billion years after the Big Bang, using the MeerKAT radio telescope and the James Webb Space Telescope. This discovery pushes the observational boundary of FRBs to earlier in cosmic history, providing new insights into the universe's evolution, star formation, and magnetic fields across gigaparsec scales.
Astronomers using the ASKAP radio telescope identified a nanosecond bright radio burst originating from a 60-year-old satellite, Relay 2, likely caused by electrostatic discharge or micrometeoroid impact, highlighting new ways to monitor satellite activity and understand fast radio bursts within our galaxy.
Astronomers using the ASKAP radio telescope in Australia detected a brief, bright radio burst originating from within 4500 km of Earth, traced to the old Relay 2 satellite, likely caused by an electrostatic discharge or space debris impact. This discovery highlights the potential for ground-based monitoring of satellite activity and the ongoing search for cosmic signals.
A mysterious radio burst detected in 2024 was traced to NASA's decommissioned Relay 2 satellite, likely caused by electrostatic discharge or micrometeoroid impact, highlighting the importance of understanding anthropogenic signals and space environment hazards.
A dead NASA satellite from 1964, Relay-2, unexpectedly emitted a powerful radio burst nearly 60 years after its launch, likely due to electrical buildup or impact, highlighting challenges in distinguishing cosmic signals from space debris.
A team of astronomers discovered that a mysterious fast radio burst (FRB) detected last year originated from the long-dead NASA satellite Relay 2, which was passing overhead at the time, rather than a distant cosmic source, revealing new insights into signals from space and space debris.
Researchers have detected a new and extremely powerful fast radio burst (FRB) originating from a group of merging galaxies located more than halfway across the universe. This FRB, named FRB 20220610A, is four times more energetic than other FRBs and its discovery sheds light on the mysterious origins of these astronomical events. The use of the Hubble Space Telescope was crucial in pinpointing the exact location of the FRB, which is in a peculiar environment of a galaxy interacting with at least six others. The findings were presented at the 243rd meeting of the American Astronomical Society, and researchers hope that further discoveries of FRBs will provide more insights into their causes and origins.
