The electrons may have wafted off the young stars and then been energized by the intense magnetic field around an unseen neutron star or a black hole somewhere inside the cluster.

(Sunspots are relatively cool because their intense magnetic fields keep a lid on the heat rising from inside the sun.)

As these monsters feast on clouds of gas, their intense magnetic fields could thrust jets of high - energy particles out into space at virtually the speed of light.

Observers spotted them with the Hubble Space Telescope in 2012, detecting the fluorescence of oxygen and hydrogen in the water molecules as they were bombarded by electrons whipped up by Jupiter's intense magnetic fields.
