Scientists say that the construction of a vast new radio telescope array in the Utah desert — known as the Deep Synoptic Array 2000 — could uncover some of the biggest outstanding mysteries in ...

A new three-dimensional (3D) vector parabolic equation method (PEM) is proposed to study the propagation of electromagnetic waves in tunnels, which is particularly useful for modeling wave propagation ...

Scientists say the phenomenon could “hint at” new particles or interactions between known particles that haven’t been ...

Radio telescopes saw a strange burst of unknown energy in June 2024. Now we know it was from Relay 2, an early ...

Using the Very Large Array (VLA), astronomers have performed radio observations of a galaxy cluster Abell 2744, nicknamed ...

A NASA satellite that’s been orbiting as space junk since 1967, Relay 2, emitted an unexpected, powerful radio burst that ...

This paper analyzes radio wave propagation characteristics in a tunnel with a rectangular cross section and multi-layer-structure walls. These walls consist of a surface moisture layer, concrete, ...

Around midday on June 13 last year, my colleagues and I were scanning the skies when we thought we had discovered a strange ...

Astronomers detect 10 billion-year-old radio waves from a distant galaxy cluster SpARCS1049, revealing a mini-halo that ...
