In a groundbreaking discovery, astronomers have detected a mysterious radio-emitting celestial object that defies current astrophysical understanding. This revelation, brought to light by the CHIME/FRB Pulsar Survey, introduces a unique cosmic entity that could challenge and expand our comprehension of long-period radio transients. Known as CHIME J1634+44, this extraordinary object not only spins at an unusually slow pace but also exhibits a rare phenomenon of accelerating rotation. Such an object has never been observed before, making this discovery a beacon for future astronomical research and exploration. A Signal with an 841-Second Beat and a Unique Pulse Structure The enigmatic CHIME J1634+44 impresses with its remarkable spin period of 841 seconds, placing it among the slowest-rotating radio emitters ever documented. Even more intriguing is its secondary periodicity of 4,206 seconds, suggesting a possible interaction with a companion object, likely through gravitational or material dynamics. Since its discovery in October 2022, CHIME J1634+44 has been observed experiencing reactivation bursts, totaling an impressive 89 unique bursts over a span of 4.5 years. This object stands out because of its consistent emission of fully circularly polarized radio bursts, a rarity among long-period emitters. Such characteristics imply that CHIME J1634+44 might not be a typical slow-rotating pulsar but rather something more exotic. It could potentially be a magnetic white dwarf, a magnetar, or an entirely new form of celestial object. This opens up exciting possibilities for scientists to explore and understand the nature of such cosmic phenomena. 'They Built Them by the Water!': New Study Uncovers Lost Nile Branch That Once Guided the Construction of the Egyptian Pyramids A Discovery Born from High-Precision Sky Monitoring The revelation of CHIME J1634+44 was made possible by the CHIME/FRB single-pulse pulsar survey, which utilizes an advanced triggering algorithm to isolate signals within the Milky Way based on dispersion measures (DM). The researchers, as documented in their study, meticulously used the CHIME/FRB trigger criteria for all sources with a DM low enough to be considered within the Milky Way galaxy, according to both the NE2001 and the YMW16 DM models. The Canadian Hydrogen Intensity Mapping Experiment (CHIME) has been pivotal in uncovering a wide array of transient radio phenomena, ranging from fast radio bursts (FRBs) to more slowly varying emitters like CHIME J1634+44. Its capability to monitor vast sections of the sky with high sensitivity and temporal resolution is ideal for detecting these elusive, low-frequency signals, making CHIME an essential tool in the study of cosmic radio transients. 'They Can See Us Even in Silence': China's New Magnetic Wake Tech Shatters Submarine Stealth in Shallow Waters Like the Taiwan Strait Acceleration in Spin Suggests Powerful Forces at Play A particularly unusual characteristic of CHIME J1634+44 is its accelerating spin, marked by a negative period derivative of approximately −9.03 seconds per second. This finding is unexpected, as known neutron stars or pulsars typically exhibit spin-down behavior due to energy loss through radiation or winds. The observed spin-up suggests either material accretion from a companion star or possibly energy injection via gravitational wave radiation. If confirmed, this would make CHIME J1634+44 the first known long-period transient to exhibit such spin behavior, challenging current theoretical models and paving the way for new insights into angular momentum transfer in extreme astrophysical systems. This discovery could significantly alter our understanding of how these cosmic entities function and evolve, providing a fresh perspective on traditional pulsar mechanics. 'They Can Dodge Anything We Throw at Them': China's Secret Algorithm Outsmarts Even America's Most Advanced Hypersonic Defenses A Key to Unraveling the Long-Period Transient Puzzle Long-period transients remain among the least understood types of radio sources. Their origins, emission mechanisms, and evolutionary pathways are largely speculative. The unique attributes of CHIME J1634+44 may hold the key to unraveling the mysteries surrounding this enigmatic class of astrophysical phenomena. The researchers emphasize the scientific potential of CHIME J1634+44, describing it as an important test bed for long-period transient emission theories. Its distinctive traits—particularly the combination of long periodicity, spin acceleration, and circular polarization—set it apart from the known neutron star and magnetar populations. If ongoing and future observations can clarify the mechanisms behind its emissions, they may help astrophysicists distinguish between competing origin models and inspire new theoretical frameworks. This discovery not only poses new questions about the nature of cosmic radio emitters but also challenges existing paradigms in astrophysics. As researchers continue to study CHIME J1634+44, they are likely to uncover insights that may redefine our understanding of the universe. What other cosmic mysteries lie hidden, waiting to be discovered through the eyes of advanced astronomical technology?

This Satellite Died in 1967. For Some Reason, It Just Spoke to Us Again.
Here's what you'll learn when you read this story: A fast radio burst (FRB) was detected coming from near-Earth orbit, which is unusually close considering the closest known FRB was detected tens of thousands of light-years away. It turned out that the signal came from a satellite that had been decommissioned in the late 1960s after its instruments broke down. What triggered the electrostatic discharge that caused the signal is still uncertain, but investigating further could help us figure out how to prevent damage to live spacecraft. Space is chock-full of mysterious signals. While most come from natural cosmic phenomena, one recent fast radio burst (FRB) had all the markings of advanced technology, which baffled scientists until they traced it back to a surprising source: our own space junk. The accumulation of human junk has gone beyond Earth's landfills. Orbiting our planet is an entire cosmic dumpster of space garbage, from the 23,000-ish larger pieces of refuse, such as decommissioned satellites, to over 100 million stray fragments of metal and glass and whatever else is flying around. Satellites that retire are deorbited into a graveyard orbit within 25 years of their missions ending. This is the case with NASA's Relay 2 satellite, which took off in 1964 until its transponders glitched. It hung dead in near-Earth orbit by 1967 and has beamed nothing down since—until now. Get the Issue Get the Issue Get the Issue Get the Issue Get the Issue Get the Issue Get the IssueGet the Issue Get the Issue Relay 2 didn't suddenly reactivate. Instead, something triggered it to send a FBR so fast it was gone in a nanosecond, to the surface, which was then picked up by the Australian Square Kilometer Array Pathfinder (ASKAP). Astronomer Clancy James and his research team found the source coming just 4,500 km (about 2,796 miles) from Earth. This meant that it couldn't possibly have issued from a neutron star, magnetar or zombie galaxy. When the researchers tracked it to Relay 2, they figured something must have been interacting with the Apollo-era relic. 'The charging of spacecraft in orbit due to interactions with the space environment has been a well-known phenomena since the early days of the space program,' the scientists said in a study recently accepted for publication in The Astrophysical Journal Letters and posted on ArXiv. 'Accumulation of electrons and ions can lead to large voltage differentials between spacecraft surfaces, and between the spacecraft and space plasmas.' The most likely culprits? Electrostatic discharge (ESD) or plasma discharge caused by a collision with a rogue micrometeoroid. Spacecraft that are still alive and carrying out their missions need to be designed to avoid hazardous ESD currents. That still doesn't make spacecraft totally immune. Most don't have onboard monitors to detect levels of charge buildup, and that buildup usually isn't detected until after damage has been done. This is why scientists have proposed that ground-based radio monitors watch for ESD, but no system is yet capable of simultaneously observing large numbers of spacecraft. On June 13, 2024, ASKAP caught the FRB from Relay 2 using its Commensal Realtime ASKAP Transients Survey (CRAFT) detection system. FRBs are so powerful that they take only milliseconds to emit the radio energy of 500 million suns. They can travel anywhere from millions to billions of light-years through the void of space, with the closest one coming from a magnetar in our galaxy that is 30,000 light-years away. This is why finding an FRB so close to Earth threw James off until he found it originated from Relay 2. While this FRB could have been set off by a micrometeoroid, which can also produce radio emissions, James thinks it is more likely the signal was the result of electrostatic discharge. The electrons and ions accumulated by satellites can eventually reach a high enough voltage to release discharge. ESD is already known to cause radio frequency pulses. Such a powerful burst as an FRB was unexpected, and the researchers have yet to find what exactly the trigger was. Future investigations could help them figure out ways to protect live spacecraft. 'When sufficient voltage is achieved, electrostatic discharge (ESD) occurs, typically be- tween nearby surfaces/materials on the spacecraft. ESD does not depend on the operational nature of the spacecraft,' the scientists said. 'So ESD from a satellite decommissioned 60 years ago is entirely plausible.'
