Visible light is just one part of the electromagnetic spectrum that astronomers use to study the universe. The James Webb Space Telescope was built to see infrared light, other space telescopes ...

Today's robots tend to use one of three imaging techniques: cameras, LIDAR, or radar. Cameras see virtually the same views we do, meaning they're susceptible to smoke, fog, light reflections, and ...

Researchers propose that hydrogen gas from the early Universe emitted detectable radio waves influenced by dark matter. Studying these signals, especially from the Moon’s radio-quiet environment, ...

Supermassive black holes reside in some of the biggest galaxies in the universe. They tend to be billions of times more massive that our Sun, and not even light itself can escape a black hole once it ...

New research has traced a radio burst from deep in the Milky Way back to its original source. Mark Garlick/University of Warwick/ESO Astronomers are dialed in for this discovery. Researchers for the ...

Add Yahoo as a preferred source to see more of our stories on Google. Antarctica’s vast ice sheet conceals a world of mysteries, from ancient river-carved landscapes to unexplained radio pulses. Cover ...

Pulsars are ultra-dense, rapidly spinning, and highly magnetized remnants of dead stars. They act like cosmic lighthouses, sending out regular pulses of radio waves and sometimes gamma rays in beams ...

Electromagnetic waves are packets of energy travelling all around us. Some of these waves have lots of energy, and some have less. We call the lowest energy electromagnetic waves radio waves. There’s ...

An intensely magnetic neutron star roughly 15,000 light-years from Earth is stumping astronomers with its ultra long periods, unleashing radio waves into the cosmos every 22 minutes. Neutron stars ...

Brown dwarf stars rarely emit radio waves. Here scientists have found the coldest star yet emitting at these long wave lengths. Understanding the science of 'ultracool brown dwarfs' will help deepen ...

Have you ever wondered what the invisible world of radio waves might look like if you could actually see it? Rootkid explains how his project, the Spectrum Slit, transforms the unseen chaos of ...
