A mysterious, 100-year solar cycle may have just restarted
New research suggests that the unexpected intensity of the ongoing solar maximum may be partly tied to a lesser-known, 100-year solar cycle. If true, solar activity could spike further in the coming decades. But some experts are skeptical.
SpaceX's Starlink satellite constellation 'under threat' by Russia and China
