Flights Grounded In Greece Due To Radio Frequency Loss
Flights at Greek airports were cancelled or delayed Sunday after a technical problem knocked out airspace radio frequencies, the country's civil aviation authority said, calling the outage "unprecedented".

New Analysis of 1977 Wow! Signal Reveals Stronger Cosmic Mystery
The famous 1977 “Wow!” signal — a mysterious radio burst detected by Ohio’s Big Ear telescope — has been reanalyzed using modern computing techniques. Researchers digitized old telescope records, finding the signal was about four times stronger than first thought, peaking at 250 Janskys. The recalculations also refined its frequency and s...

Tracked, Locked, Confirmed Kill: New Akash Missile Destroys Targets In Ladakh
At 15,000 feet in Ladakh, the Army achieved a significant milestone with the Akash surface-to-air missile. The new variant of the system - Akash Prime - scored two confirmed kills during a test run.

NASA Astronauts Williams and Wilmore Complete Successful Spacewalk to Remove Faulty Unit
NASA astronauts Sunita Williams and Barry Wilmore successfully completed a 5-hour and 26-minute spacewalk on January 30, 2025, to remove a faulty radio frequency group (RFG) from the International Space Station (ISS). Despite several failed attempts in 2023 and 2024, their persistence paid off, marking a significant achievement. Williams also set a...

Astronomers Uncover New Details of CIZA0107 Galaxy Cluster Merger with VLA
A team of astronomers, led by Emma Schwartzmann from the U.S. Naval Research Laboratory, used the Very Large Array (VLA) to study the nearby galaxy cluster merger CIZA J0107.7+5408 (CIZA0107). The observations provided new insights into the dynamics of galaxy mergers, revealing a disturbed system with two subclusters and diffuse radio emission span...

Asteroids Impacting Neutron Stars May Be the Cause of Fast Radio Bursts
Research suggests asteroid impacts on neutron stars may be the cause of mysterious fast radio bursts (FRBs). These collisions release enormous energy and match observed FRB frequency. Scientists believe interstellar objects colliding with neutron stars could account for their rate and occurrence, while repeating FRBs may stem from asteroid belts. O...

What Is A Pager And Why Hezbollah Still Relies On This Outdated Device
A pager or ‘beeper’ is a small, portable communication device that receives short messages, typically numeric or alphanumeric, over a radio frequency signal.

SETI Uses Radio Frequencies to Look for Alien Life in More Than 1,000 Galaxies
Search for Extraterrestrial Intelligence (SETI) recently conducted a search of more than 1,300 galaxies for signs of alien life using unexplored low radio frequencies. The search was reportedly performed using the Murchison Widefield Array (MWA), a radio telescope located in the Australian outback. This effort targeted radio frequencies in the 80...

Indian Astronomers Discover 34 New Enormous Cosmic Radio Sources
The GMRT, located near Pune, India, played a crucial role in this discovery. This powerful telescope surveyed the radio sky at a low frequency, making it ideal for detecting these faint, distant objects.
