City-sized neutron stars may actually be larger than we thought

Scientists have made new estimates of the size of mysterious neutron stars, revealing that the ultra-dense stellar corpses are slightly larger than previously thought.

According to the new estimates, published on April 27 in the journal Physical Review Letters, neutron stars – the densest known objects in the universe other than black holes – have a radius between 8.2 and 8.9 miles (13.25 and 14.25 kilometers).
