  "account": "According to recent research published in The Astrophysical Journal Letters, Chinese scientists have discovered a real three-star system using the world's largest single-dish radio telescope, FAST. This system, located approximately 7,000 light years from Earth, consists of two dead stars and a living one, all orbiting each other in a harmonious cosmic dance. One of the dead stars is a pulsar, a rapidly spinning core left behind after a massive star's explosion, which completes an orbit around its partner white dwarf every eight days. Meanwhile, a sun-like star orbits the pair from a distance, taking 73.5 years to complete one lap. This particular system is unique, as it is the second known example of a three-star system containing a millisecond pulsar, a highly rare phenomenon due to the instability caused by the pulsar's explosion. The discovery has the potential to test key aspects of Einstein's theory of gravity, particularly the strong equivalence principle, which states that all objects fall at the same rate regardless of their mass. Due to its peculiar characteristics, such as the pulsar's unexpectedly rapid slowdown, scientists hypothesized the presence of a sun-like star in the system, which they confirmed by combining data from FAST with observations from other telescopes. The researchers believe that the three stars originated from the same gas cloud and have aged at different rates due to their varying masses. As the sun-like star completes its orbit in 2036, scientists anticipate a more precise measurement of the system's dynamics.",
  "summary": "In author and computer engineer Liu Cixin’s science fiction hit The Three-Body Problem, three suns throw a doomed world into chaos. Chinese astronomers say they have found a real three-star system that is far better behaved. Using FAST, the world’s biggest single-dish radio telescope in southwestern China, the researchers found two dead stars and a “living” one locked in a steady cosmic dance…",
