Better than a Game of Thrones spinoff! 🌟
 In a groundbreaking feat, the @hubbleesa has directly measured the mass of a solitary white dwarf – the remnant core of a Sun-like star. Weighing in at about 56% of our Sun’s mass, this measurement supports current theories on star evolution and white dwarf structure. Using gravitational lensing, where Hubble tracked the faint bending of light from a distant star, astronomers achieved precision thought impossible for stars beyond our own Solar System.
