Neutron stars are created when massive stars reach the ends of their lives and are composed of the densest matter in the known universe.
Neutron stars are not only mines for clues to dense matter physics but may also be the auspicious sources of half of all nuclei heavier than A = 60 in the universe, including the auric isotopes. Although the cold dense matter above the nuclear saturation density cannot be directly explored ...
They could potentially take a census of black-hole mergers, spot the collisions of ultra-dense neutron stars(中子星),probe the inner dynamics of exploding stars and discover theoretical “cosmic strings” left over from the big bang. These waves will be particularly useful for studying black ...
It’s so dense that the mass of all living humans would fit into one cubic centimeter of neutron star matter. That’s roughly a billion tons in a space the size of a sugar cube. Put another way, that’s Mount Everest in a cup of coffee. From the outside, a neutron star is ...
objects orbiting into each other. The black hole collision was just one example of what gravitational waves can tell us. Other high-energy astronomical events will leave gravitational echoes, too. The collapse of a star before it explodes in a sup...
With almost all the material inside the star converted into a dense neutron soup, further collapse is prevented by the neutron degeneracy pressure, capable of forming a remnant core a couple of times the mass of the sun but no bigger than a small town: a neutron star. Neutron stars have ...
The inner zone, its nuclear fires no longer burning, will begin to collapse under the influence of its own weight and will contract into a tiny hot core, dense and dim. An opposite fate will await the outer region, a loosely held-together ball of gas. A shock wave caused by the inner...

(Neutron stars are so dense, a "sugar-cube-sized amount of material would weigh more than 1 billion tons, about the same as Mount Everest!" NASA explains.) Another group of researchers found the object was smaller, at some 1.6 and 4.4 times the mass of the sun. An object some 1.6 ...
