This is reported by Space telescope.

Despite the fact that the galaxy looks calm enough recently, inside it there was a powerful explosion.

NASA noted that large-scale energy emissions are among the most rare cosmic phenomena and last from a few seconds to an hour. But at the same time, a bright glow after a flash is retained for a long time.

We add that so far scientists have not been able to find out why an explosion took place on a spiral galaxy.

Recall, as previously reported "URA-Inform", in Antarctica, a giant iceberg with an area of ??267 square kilometers, which recently broke away from the ice sheet, split into pieces.
