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 the University of Illinois Urbana-Champaign developed an instrument to measure the density of the dust that kicks up when spacecraft thrusters interact with planetary surfaces as it ...

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 ...

An interdisciplinary team of researchers from the Georgia Institute of Technology has received a $2 million federal grant to create tools that will provide the clearest three-dimensional images yet of ...
