Shake, Rattle, and Probe

by Damond Benningfield 25 August 202217 January 2023

Helioseismology allows scientists to study the interior of the Sun, solve some basic physics mysteries, and forecast space weather.

In this digital illustration, three small rocky planets orbit a pulsar. One planet is large in the foreground and has a polar aurora and cratered surface. The other two are smaller in the background. A pulsar appears at top left in the image and is depicted as a bright white point source emitting white beams at 5 o’clock and 11 o’clock. Purple and green loops and swirls surround the point of light and represent the strong magnetic field of a pulsar.
