Hot spots and tunnels to neighboring "superbubbles" seem to have been created by supernovas and infant star outbursts.

A small but mighty cluster of sunspots have made their biggest mark yet on Earth's magnetosphere—and on the radio signals that pass below it. After releasing an X2.3-class solar flare on Nov. 6, radio ...

In this instance, with such an intense amount of ultraviolet (UV) radiation that accompanied the flare, a shortwave radio ...
