Reliably guiding and capturing optical waves is central to the functioning of various contemporary technologies, including communication and information processing systems. The most conventional ...

Advanced space travel relies on a fundamental understanding of the restricted three-body problem (RTBP), in which one of the three bodies—typically a spacecraft—is so small that its gravity doesn’t ...

Physicists have discovered a tiny asteroid, about one kilometer wide, that is locked into the same orbit as Earth—only the second such cosmic body of its type that has been identified to date. And now ...
