The basic design of the radio antenna hasn’t changed in a century. The antenna is usually a set of metal rods roughly half the size of the wavelength they are designed to receive. The electric field ...

There is more to light than meets the eye, and it teaches us a lot about the universe. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Parts of ...

Pyramid power: radio waves incident from above are focussed to a region below the pyramid (shown in red). Also in red are the waves concentrated in the rectangular King's Chamber within the pyramid.

Free-space (a) and guided-wave (b) and (c) ranging experimental schematics. Using parameter estimation techniques on interference-class waveforms, we estimate the distance between two scattering ...

How much does the universe weigh? It’s a simple question with an answer so complex that scientists have devised several ways to calculate the mass of, well, everything and arrived at many different ...

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 ...

Astronomers have discovered a new type of stellar object that could change their understanding of extreme celestial bodies in the universe. Initially, Curtin University doctoral student Tyrone ...

Due to how light travels, we can only see the most eye-popping details of space—like nebulas, supernovas, and black holes—with specialized telescopes. Electromagnetic Spectrum: the visible range ...
