Dark Sun
From Starsonata Wiki
Dark Suns, also known as dark stars, are an unusual type of star that reduce visibility rather than raise it. They are the opposite of Suns and oftentimes give a shield aura. Like suns, some can cause damage to ships that fly too close, and they can produce various auras as well.
Anti-panels must be used in the presence of a dark sun as Solar Panels will drain energy.
