Feeling a bit "starstruck" by Medusa's infamous gaze? Good news: you'll live to see another day as her head resides well up in the night sky as Algol, the "Demon Star" whose brightness had people’s heads spinning like a Greek tragedy: In actuality, this cosmic luminary in the Perseus constellation owes its fluctuating radiance to an eclipsing binary system, where components Beta Persei Aa1 and Beta Persei Aa2 orbit, and occasionally eclipse, each other every 681 Earth days.

5. Algol: Celestial Drama Queen

Once upon an ominous night, the Perseus constellation threw a star-studded party, and its most scandalous guest, Algol (aka the Demon's Head), had a very public face-off – but fear not, no stardust was spilled: In reality, the Algol star system is an eclipsing binary, which means its brightness fluctuates as one star passes in front of the other, and despite its eerie reputation, modern astronomers leverage this system to study binary stars and unravel the mysteries of stellar evolution.

6. Desperate Housewives of the Cosmos

It's a celestial case of neighbors with the starriest of feuds; think "Desperate Housewives" of the cosmos, only involving Greek myths instead of TV drama: Despite the connection between Cassiopeia and Perseus in mythology, the two constellations hold court in separate quadrants of the night sky, each with its own distinct origins and lore. Curiously, both can be spotted in a friendly celestial tête-à-tête from latitudes north of 35°N, giving stargazers in the Northern Hemisphere a double dose of astronomical royalty.

7. Perseus & Medusa's Galactic Battle

In a celestial twist worthy of a blockbuster sequel, the Perseus constellation found itself embroiled in an epic battle of the stars, thanks to its namesake hero's (literally) head-turning victory over Medusa: The constellation is linked to the legendary story of Perseus, who decapitated the snake-haired Gorgon, Medusa, and used her petrifying gaze to vanquish foes. Some stars in this heavenly assemblage even adopt character names from the tale – such as Algol, symbolizing Medusa's eye – though, rest assured, no interstellar hand-me-downs from Perseus have been discovered thus far.

9. Algol: The Temperamental Star Diva

Ever heard of a star that's more temperamental than a reality TV diva? Enter Algol, the celestial drama queen: This star in the Perseus constellation is actually a prototype of a group of eclipsing binary stars called Algol variables, aptly named after the Arabic term for "The Demon's Head". At a distance of 92.8 light-years away from Earth, Algol puts on quite a show with its regular dimming and brightening, thanks to its two stars playfully eclipsing one another and causing noticeable variations in its brightness.
