On Dec. 27, 2004, scientists detected the largest gamma-ray burst ever recorded. It came from a magnetar–a neutron star with an enormous magnetic field–50,000 light years away. Its powerful rays ...

Cassini mission data shows Saturn’s moon Enceladus generates Alfvén waves extending over 504,000 km, circulating energy and momentum through Saturn’s magnetosphere, according to Universe Today and ...

Scientists at Japan’s Nagoya University have used Japan’s extensive network of GNSS receivers to create the first 3D images of atmospheric disturbances caused by the 2024 Noto Peninsula Earthquake.

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 ...

Photo of the Earth with radio waves, depicted in purple, flowing across it. HF and VHF waves travel through the ionosphere. But a phenomenon called sporadic-E can interfere with these frequencies.

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 ...
