Astronomers have found a clever new way to slice and dice the flickering light from a distant star in a way that reveals the strength of gravity at its surface. That is important because a star’s ...

Observation and origin of the elastogravity signal preceding direct seismic waves. The map shows the location of the seismometers (triangles) detecting the prompt signals just after the beginning of ...
