A closed door feels absolute. Light stays in one room, darkness settles in the next, and the boundary seems obvious enough to ...

Astronomers from the International Center for Radio Astronomy Research (ICRAR), in collaboration with international teams, have made a startling discovery about a new type of cosmic phenomenon. The ...

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 ...

When the New York Times first wrote about "mysterious radio waves" from the cosmos in 1933, they made sure to note one fundamental caveat: "No Evidence of Interstellar Signaling." Indeed, the radio ...

WASHINGTON — Researchers have developed a new metasurface-based antenna that represents an important step toward making it practical to harvest energy from radio waves, such as the ones used in cell ...

Slowly repeating bursts of intense radio waves from space have puzzled astronomers since they were discovered in 2022. In new research, we have for the first time tracked one of these pulsating ...

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 ...

A team of international astronomers have discovered a new cosmic object emitting both radio waves and x-rays. Astronomers from the International Centre for Radio Astronomy Research (ICRAR), in ...

Researchers report that lab tests of a new metasurface-based antenna that can harvest 100 microwatts of power, enough to power simple devices, from low power radio waves. This represents an important ...
