Earth's radio bubble, originating from the first broadcast in 1906, has expanded to a radius of 119 light-years, reaching some nearby stars but only a tiny fraction of the Milky Way, and is gradually diminishing as technology advances.
Humans have inadvertently created a human-made barrier around Earth by using radio waves in the VLF range, which influence the Van Allen radiation belts and could potentially be used to protect the planet from cosmic radiation and solar storms.
Astrophysicists have detected radio signals from the exoplanet YZ Ceti b, suggesting it may have a magnetic field that interacts with its star, providing insights into how rocky planets can retain their atmospheres despite stellar activity.
Israeli scientists have proposed a novel method to study dark matter by detecting faint radio waves emitted during the universe's early period, potentially revealing the properties of dark matter through space-based observations, such as those planned with the Square Kilometre Array.
Strange circular radio wave structures in space, known as odd radio circles (ORCs), have puzzled astronomers since their discovery in 2019. A recent study of one such ORC, J0356-4216, suggests they may be caused by shock waves from past galaxy activity, such as black hole flares or galaxy collisions. These structures are visible only in radio wavelengths and could provide new insights into cosmic phenomena.
A new study suggests that radio waves can be used to safely and painlessly restore the sense of smell by targeting brain nerves, showing promise for treating olfactory loss without surgery or chemicals, though further research on affected individuals is planned.
A NASA satellite that went offline in 1967 emitted a brief, bright radio signal in 2024, likely caused by a spark of built-up electricity or space debris impact, providing insights into electrostatic discharges in Earth's orbit.
Astronomers have discovered the most distant mini-halo surrounding a galaxy cluster from 10 billion years ago, revealing that energetic processes involving black holes and cosmic collisions have shaped galaxy clusters throughout most of the universe's history, providing new insights into the early universe's formation.
A defunct NASA satellite, Relay 2, unexpectedly emitted a powerful radio wave in 2023, possibly due to electrostatic discharge or micrometeoroid impact, highlighting the mysterious reactivation of old satellites and the potential for space debris to generate signals detectable from Earth.
Scientists using the ANITA experiment in Antarctica have detected mysterious radio signals from beneath the ice that defy current understanding of physics, possibly indicating unknown particles or interactions, prompting further research with advanced detectors like PUEO.
NASA's ANITA experiment detects mysterious upward-moving radio pulses from deep beneath the Antarctic ice, which cannot be explained by known particles like neutrinos, suggesting potential new physics or unknown radio propagation effects, with future missions like PUEO expected to shed more light on these anomalies.
University of Wisconsin-Milwaukee researchers, as part of a global team, discovered a unique space object emitting both radio waves and X-rays, potentially leading to the identification of a new star type and advancing understanding of the universe. The discovery involved advanced telescopic techniques and may influence technological fields like AI and algorithms, inspiring future generations of scientists and technologists.
Astronomers have discovered a unique cosmic object, ASKAP J1832-0911, 15,000 light-years away in the Milky Way, that emits both radio waves and X-rays in a 44-minute cycle, potentially revealing new physics or stellar evolution models. The simultaneous detection by radio and X-ray telescopes suggests many more such objects may exist, challenging current understanding of stellar phenomena.
A mysterious object in our galaxy, ASKAP J1832-0911, pulses every 44 minutes emitting both radio waves and X-rays, challenging existing classifications of stars like pulsars, white dwarfs, or magnetars, and prompting new theories about stellar magnetic fields and behaviors.
Astronomers have discovered a new mysterious object in the Milky Way emitting both radio waves and X-rays with a 44-minute cycle, possibly a highly magnetized dead star or an unknown exotic object, located 15,000 light-years away, raising questions about its nature and whether more such objects exist.
