Ring of fire around black hole revealed for first time
... observed a ring of extremely fast moving material racing around near Sag A*’s event horizon at about 30 percent the speed of light. As tantalising as the observation was, the massive cavernous abyss of the black hole still remained elusive. Even...

Researchers probe black-hole mergers with fast-powered winds
...a type of non-thermal radiation generated by charged particles spiralling around magnetic field lines at close to the speed of light. An advantage of the synchrotron radio signals is that the emission is long-lasting, hence follow-up observations can...

The mystery of neutrino mass to be solved by a calcium isotope
... electric charge. Unlike photons or charged particles, neutrinos can travel across the universe (at essentially the speed of light) without interference as they are not absorbed by intervening matter or deflected by interstellar magnetic fields. This...
