Researchers have found that the young giant planet PDS 70c emits radio light from ionized gas rather than the dusty disk astronomers long expected around such worlds. That unexpected signal reveals ...

From GPS satellites to mobile networks, modern technology relies on ultra-precise radio signals. Engineers have long tried to generate them on chips using interactions between light and sound, but the ...

One of the longest-standing techniques in humanity’s search for life beyond Earth may be causing scientists to miss alien signals entirely, a new study finds. Since the very beginnings of the search ...
