Summary:
- Astronomers have finally solved the mystery of the origin of cosmic X-ray blasts, which are powerful bursts of X-ray radiation coming from deep space.
- These X-ray blasts are caused by the collision of two dense neutron stars, which are the collapsed cores of massive stars that have exploded as supernovae.
- The collision of the neutron stars creates a black hole and releases a huge amount of energy in the form of X-rays, which can be detected by telescopes on Earth.
