Exclusive: New Drone Built By IIT Jammu Can't Be 'Jammed Or Detected'
Unlike others, the drone developed by IIT Jammu students evades detection by ditching traditional radio frequencies using advanced technology.

US Pilots Land In Trouble For 'Meowing' And 'Barking' On Emergency Flight Channel
A viral audio clip of pilots meowing and barking over an emergency aviation frequency has triggered an investigation by FAA.

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...
