Despite the name, some black holes effectively “shine” as they suck up nearby material with such force that it begins to glow. New research reveals a new method for detecting these active black holes.
After six decades during which it tracked lunar missions, spotted distant pulsars and quasars, and even expanded our concept of the size of the Universe, the Parkes telescope is still going strong.
Astronomers have taken a close-up look at the jets of plasma streaking away from a supermassive black hole - one of the strangest and most energetic features of galaxies.
Fast radio bursts are the focus of a young and fascinating field of astronomy. Researchers just released data on more than 500 new bursts, quadrupling the total number of detected events.
Wi-Fi has become a fundamental part of modern digital life, but its foundation is the same as the technology that allowed your great-grandparents to listen to their favorite radio programs.
When the USSR launched the world’s first satellite, Sputnik 1 didn’t do much other than regularly “beep” over the radio. Yet, this simple sound is associated with the beginnings of space exploration.
Should we be concerned about the health effects of 5G? The short answer is no – there’s no substantiated evidence that the electromagnetic energy used by mobile telecommunications causes harm.
Astronomers found something not predicted by current theory when they took a closer look at the emissions from a neutron star with a very strong magnetic field.
Did your holiday gift list include radiation-shielding undies to protect your privates from cellphone radio waves? A radiation expert explains they’re unnecessary – your phone won’t affect your fertility.
The Murchison Widefield Array sits in remote Western Australia far from noisy civilisation so it can help us understand the universe by tuning into radio waves from the distant cosmos.
New research provides a compact but powerful way for Mars rovers to communicate directly with Earth via an array of smaller antenna elements, bypassing the need for an intermediary.
