Antenna

The world's largest radio telescope is taking shape. The Square Kilometre Array will be of a scale never seen before, and with the first prototype dish recently unveiled, the search for answers to some of the most fundamental questions about the universe and its origins is set to begin.

To look through space is to look through time. Astronomers have now peered right back to the “Cosmic Dawn” – when the first stars were beginning to fire up – by picking up an extremely faint radio signal that marks the earliest evidence of hydrogen, just 180 million years after the Big Bang.

Though a long accepted tenet in physics, no experiment has ever directly observed the wave/particle duality of light. Now researchers at the École polytechnique fédérale de Lausanne (EPFL) in Switzerland claim to have captured a photograph of light as both waves and particles in the same image.

The CSIRO's ASKAP radio telescope in Western Australia that will eventually form part of the upcoming Square Kilometer Array (SKA) recently began producing high-quality images of the sky using only six of its 36 antenna array.

Contrary to recent reports, the High Frequency Active Auroral Research Program, also known as HAARP, is currently in hiatus between two operating contractors rather than being permanently shut down.

A new "Wi-Vi" system developed at MIT can see through walls to track moving people using low-cost Wi-Fi technology.

Scientists from Tel Aviv University are creating what could be much more efficient solar panels, utilizing metallic "nanoantennas" instead of silicon semiconductors.

Using carbon nanotubes, MIT chemical engineers have now found a way to concentrate solar energy 100 times more than a regular PV cell.
