A stellar concert is playing out in the night sky, and scientists are learning how to listen to it like never before. Deep inside stars, sound waves move through hot gas, creating vibrations. These ...

Sound is usually treated as the most familiar of physical phenomena, the background noise of daily life rather than a frontier of fundamental physics. Yet in laboratories around the world, carefully ...

In context: Sound waves typically propagate in forward and backward directions. This natural movement is problematic in some situations where unwanted reflections cause interference or reduced ...

Earthquakes create ripple effects in Earth's upper atmosphere that can disrupt satellite communications and navigation systems we rely on. Scientists have now used Japan's extensive network of Global ...

Scientists at MIT have directly captured signs of “second sound” in a superfluid for the first time. This bizarre phenomenon occurs when heat moves like sound waves through an unusual state of matter.

Global Navigation Satellite System (GNSS) receivers help with precise location tracking and can detect disturbances in the upper atmosphere (ionosphere) by measuring delays and changes in ...
