Scientists have discovered the most powerful blasts of energy in the known universe. Dubbed extreme nuclear transients, or ENTs, the cosmic explosions are unprecedented in their intensity.

"The explosions of white dwarfs play a crucial role in astronomy," stated Priyam Das, a PhD student at the University of New South Wales Canberra and study leader. Das further described the findings ...
