Old stars blast heavy metal

[scourge]

Astronomers have now found the signature of heavy particles moving at two-thirds the speed of light in the jet from a stellar-mass black hole candidate. María Díaz Trigo and colleagues monitored the X-ray and radio emissions from a binary system thought to contain a black hole and found strong emission most consistent with highly ionized iron atoms accelerated to high velocity. Since this system is typical of other black holes in the Milky Way, this new observation indicates that similar systems are likely to all blast protons and nuclei into the surrounding space.

Cliff Richards sounds the death-knell for Heavy Metal.
Gee, that's too bad
