🪐 In the constellation Hydra, astronomers have found R Hydrae, a star that pulses in brightness over a period of about 385 days. This "Mira variable" expands and contracts like a cosmic heartbeat, changing size and light output as it nears the end of its life, giving scientists clues about the future fate of our own Sun. ✨ #stars⚡#hydra⚡#pulsation⚡#nasa⚡#galaxy⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries

🪐 In the constellation Vela, the star system HD 74423 displays an unusual cosmic phenomenon: its shape is teardrop-like rather than round, caused by the powerful gravitational pull of a nearby red dwarf companion. This distortion leads to "heartbeat" pulsations—brightenings and dimmings in rhythm with the stars’ orbits—making HD 74423 the first known one-sided pulsating star in our galaxy. ✨ #Vela⚡#heartbeatstars⚡#pulsation⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries
