In ancient times, Theta Eridani was among the brightest stars, but now its light has faded. It turned out to be a temporary flare: two stars in its system drew so close that one began to swallow the other, triggering an energy burst. Similar processes could explain unexpected brightness changes in other stars.
🎯 At its peak brightness, Theta Eridani rivaled Vega, one of the main stars of the summer sky.
