(Phys.org) -- In free-space optical communications (FSO), data is wirelessly transmitted by light propagating through open space. Among their applications, FSO systems are used for communications between spacecraft and have ...
Global warming, pollution and diminishing resources are generating great urgency among scientists seeking solutions by expanding frontiers of exploration and developing new technologies.
A team of physicists at the University of Edinburgh's School of Physics and Astronomy has used mathematical calculations to show that quantum communications across interstellar space should be possible. In their paper published ...
A team of space scientists at NASA has published a Perspective piece in the journal Nature calling for the establishment of a methodical approach to identifying life beyond Earth. In their paper, the group suggests the space ...
Astronomers accidentally discovered the footprints of a monster galaxy in the early universe that has never been seen before. Like a cosmic Yeti, the scientific community generally regarded these galaxies as folklore, given ...
