For decades, astronomers have searched for signs of extraterrestrial intelligence using radio telescopes and optical instruments, scanning the skies for artificial signals. Now, researchers are taking ...

Researchers at Carnegie Mellon University have presented some remarkable audio from a new optical microphone system that uses cameras to see and reconstruct sonic vibrations. Remarkably, it can ...

Astronomy has always relied on optical instruments, from the early Galilean telescope to fiber-fed spectrographs, so much so that astronomy and modern optics are called astrophotonics. Since ...
