For just a split second, a signal like a heartbeat flickered in a gamma-ray burst. The frequency of 909 Hz is the spin of a newborn neutron-star magnetar. Such cosmic 'lighthouses' could explain the most powerful explosions in the Universe.
🎯 A neutron star is the core of a dead star, compressed to the size of a city: a teaspoon of its material would weigh billions of tons.
🎬 In the novel 'Dragon's Egg', Robert Forward imagined life on the surface of a neutron star, where monstrous gravity speeds up time thousands of times.
