Earth-sized planet behind unusual star signals say astronomers
... are made up of many dishes or antennas spread over a wide area to collect the radio emission. This is because radio waves are a lot longer than visible-light waves, so the signals need to be collected in a different way. LOFAR for example has...

Hunting for neutrinos in the ice of Antarctica
.... In this charge separation, a changing current is created along the shower axis, which leads to an emissions of radio waves. In contrast to light, radio emission travel longer distances through ice before being attenuated which therefore allows for...
