She claimed a "black hole" in the nation's finances meant winter fuel payments would have to be axed for millions of pensioners and National Insurance hiked for employers.

By studying how this light is polarized, scientists can gain valuable clues about the shape and behavior of the extremely hot gas and debris swirling around black holes at extreme speeds.

The new results confirm earlier observations in which researchers studied quasars, the extremely bright centers of distant galaxies where supermassive black holes consume matter and emit enormous amounts of energy.

Almost every galaxy, including our Milky Way, has a black hole at its centre.

They resolve the long-debated origin of the "knee" and provide compelling observational evidence for the role of black hole systems in producing cosmic rays.
