How neutron stars ‘playing cool’ can unlock exotic physics

Scientists have discovered that there are three neutron stars born in the fires of other exploding stars, have cooled surprisingly quickly, bringing us closer to understanding the exotic nature of the matter in the cores of these extreme objects.

The discovery was made by a Spanish team led by Alessio Marino from the Institute of Space Sciences (ICE-CSIC) in Barcelona, ​​using European and American space telescopes that work with X-ray light.
