Stellar activity and plasma turbulence can significantly distort narrow radio signals before they exit their planetary systems. This phenomenon may help explain the prolonged silence observed…
While direct evidence of extraterrestrial life remains elusive unless aliens reside close to our solar system, the search for signs of life beyond Earth continues. Astrobiologists…
Radio signals are a fundamental element of the first contact subgenre in science fiction. Carl Sagan’s Contact features a compelling narrative that centers around Liu Cixin’s…
Diagram of Exoplanet K2-18b NASA Exoplanet K2-18b has generated immense intrigue due to hints of potential life; however, an extensive analysis of radio signals revealed no…
Drones are now crucial in the Russia-Ukraine conflict Diego Herrera Charcedo/Anadolu via Getty Images Stealth military radios, designed to mask signals from ambient noise, are exceptionally…
Designated FRB 20250316A, this event, referred to as rbfloat (the brightest radio flash recorded to date), took place in the outer region of the nearby Spiral…

A magnetar, a type of neutron star, can be the source of fast radio bursts Science Photo Library/Alamy A peculiar burst of light from the early…
The primordial stars, known as group III, likely formed from the abundant gases present in the young universe. These stars were responsible for generating the first…
Illustration of NASA’s Relay 1 satellite, in front of Relay 2 NASA A long-dormant satellite unexpectedly emitted a powerful radio pulse, momentarily surpassing all other celestial…
An unusual radio pulse was identified by the Antarctic Impulsive Transient Antenna (ANITA) Experiment. Various instruments were deployed on NASA balloons over Antarctica, aiming to detect…
A new batch of Starlink satellites deployed via Falcon 9 Rocket SpaceX Astronomers have raised concerns that SpaceX’s Starlink satellites emit radio waves that may jeopardize…
Askap J1832-0911 – Likely a magnetar or a highly magnetized white dwarf star – emits radio signals and X-ray pulses for 2 minutes every 44 minutes.…
A significant storm is forecasted to impact Alabama this week, as the National Weather Service has halted radio services that deliver vital weather updates for the…
Astrophysicists have discovered ILT J110160.52+552119.62, a recently discovered temporary radio source, and that the arrival of that approximately one minute pulse with a periodicity of 125.5…
The newly discovered radio jet is associated with J1601+3102, a highly radioloud kusar that spans an astounding 215,000 light years and exists just 1.2 billion years…
The source of the newly detected fast radio burst, FRB 20240209A, is located 2 billion light-years from Earth, on the remote outskirts of an ancient elliptical…
A new study has provided the first definitive evidence that fast radio bursts can originate from the magnetosphere, the highly magnetic environment immediately surrounding very compact…
Four years after the radio telescope at Puerto Rico’s Arecibo Observatory collapsed. Report from the National Academies of Sciences, Engineering, and Medicine sheds light on the…
Fast radio bursts (FRBs) are millisecond-long events detected from beyond the Milky Way. The radiative properties of FRBs favor magnetars as their source, as evidenced by…
The TRAPPIST-1 system is a compact system of at least seven exoplanets that are similar in size to Earth. Astronomers from Pennsylvania State University and the…
Neutron stars typically spin quickly, taking just a few seconds or even a fraction of a second to complete one revolution around their axis, but one…
Astronomers using the Karl G. Jansky Very Large Array have observed long-lasting aurora-like radio bursts above sunspots. This discovery could help us better understand the behavior…
It may be hard to miss, but unimaginably strong bursts of cosmic radiation happen possibly a thousand times every day. They are bright enough to overwhelm…
