(Phys.org) -- Mechanical energy is all around us, whether in the form of a vehicle's vibrations, ocean waves, or vibrating train tracks. However, much of this energy is irregular and oscillatory - for example, road bumps ...
An international team of researchers has found evidence of a ridge of radio emissions joining two galaxy clusters. In their paper published in the journal Science, the group describes their find and how it fits into cosmological ...
(Phys.org) —NASA's Voyager 1 spacecraft has experienced a new "tsunami wave" from the sun as it sails through interstellar space. Such waves are what led scientists to the conclusion, in the fall of 2013, that Voyager had ...
