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.

We are in the middle of solar cycle 25, which means that the Sun has been slowly ramping up its sunspot and flare activity for the past few years.

11 Discoveries Awaiting Us at Solar Max

by Kimberly M. S. Cartier 25 August 202230 September 2022

Each solar cycle might seem like the same old story, but one thing has changed significantly since the previous solar maximum–our technology.

The Sun, a round orange orb, is observed through an ultraviolet filter that gives its surface a mottled deep orange look. There are a few prominences along the edge of the circular disk and one loop at around one o’clock, but there are no sunspots visible on the surface.
