Debate still raging on site for super-telescope

An international consortium planning to build the world's most powerful radiotelescope is still debating whether South Africa or Australia should host the $2 billion project, an official said Friday.

Hybrid nanoantenna designed to manipulate visible light

A nanoscale optical antenna developed by researchers at A*STAR allows the manipulation of visible light waves on the scale of microchips. Such nanoantennae may enable the development of high-resolution imaging systems in ...

The Very Large Array: Astronomical shapeshifter

When the Very Large Array was completed forty years ago, it was a different kind of radio telescope. Rather than having a single antenna dish, the VLA has 27. The data these antennas gather is combined in such a way that ...

Final North American ALMA antenna delivered

(Phys.org)—After an odyssey of design and construction stretching across more than a decade, North America has delivered the last of the 25, 12-meter-diameter dish antennas that comprise its share of antennas for the international ...

NASA's new experimental antenna tracks deep space laser

An experimental antenna has received both radio frequency and near-infrared laser signals from NASA's Psyche spacecraft as it travels through deep space. This shows it's possible for the giant dish antennas of NASA's Deep ...

Dead stars could be the future of spacecraft navigation

Scientists at the National Physical Laboratory (NPL) and the University of Leicester have been commissioned by the European Space Agency (ESA) to investigate the feasibility of using dead stars to navigate spacecraft in deep ...

Video: Drone test of Hera mission's asteroid radar

This drone hauled a model of the Juventas CubeSat high into the air, as a practical test of the antennas designed to perform the first radar sounding of the interior of an asteroid.

New radio telescope will listen to the Universe on the FM-band

(PhysOrg.com) -- The first major radio telescope to be built in Britain for many decades will 'listen' to the sky at FM frequencies, providing vast quantities of data to a supercomputer in Holland, paving the way for unexpected ...
