The article explores the awe-inspiring night sky, highlighting that while we perceive awe-inspiring celestial bodies, many truths about stars, light, and visibility remain hidden. Notably, half of the stars are in multi-star systems, and the most common type, red dwarfs, are invisible to the naked eye. It is noted that stars are dynamic, moving and changing brightness, contrary to their perceived constancy. Furthermore, the article emphasizes that light pollution is decreasing the visibility of stars at an alarming rate, revealing that our view of the cosmos is diminishing.
Many glittering, twinkling stars aren't singlets like our Sun. 50% of stars exist within multi-star systems, but unaided eyes can't resolve multiple components.
Zero naked-eye stars are of the most common variety: red dwarfs. About 75% of all stars are faint, cool red dwarfs: too dim for the naked eye.
Stars' positions and brightnesses aren't eternal and unchanging. They also vary in brightness and evolve, mostly undetectable by human perceptions.
Fewer stars are now visible from Earth than ever before. Light pollution, worsening globally by 9.6% annually, means fewer visible stars than ever.
