A mysterious cosmic explosion was seen by NASA. Scientists believe that it was due to a first-time destructive event.

NASA reported how the agency's Chandra X-ray Observatory using its deepest X-ray Image discovered a mysterious cosmic explosion. The origin of the cosmic explosion was still unknown but some scientists believe that it was due to a destructive event of the stars.

The mysterious cosmic explosion lasted for about a day and had completely faded after being caught up by the Chandra Deep Field-South or CDF-S. According to Economic Times, scientists believe that the mysterious cosmic explosion seen using the X-rays started from a faint and small galaxy with a distance of about 10.7 billion years.

Franz Bauer of the Pontifical Catholic University of Chile in Santiago, Chile said that ever since the mysterious cosmic explosion was discovered, his team have been struggling to understand how it originated. "It's like we have a jigsaw puzzle but we don't have all the pieces," Bauer said.

However, though the source of the mysterious cosmic explosion is yet unknown, scientists explained three main possibilities of the event. One belief on the source of the gamma-ray burst of GRB explosion was triggered by a massive star which collapsed. Or it might be due to a merger of a neutron star with a black hole or another neutron star.

While the second explanation for the mysterious cosmic explosion is GRB that was not pointed down towards Earth or a GRB in a small galaxy. And the last possibility might be the result of a medium-sized black hole that shredded into a white dwarf star.

Consequently, co-author from the Pontifical Catholic University, Ezequiel Treister said that none of the three ideas used for explaining the mysterious cosmic explosion perfectly fits the data. But, Treister said this is a rare event and was not seen in similar events that NASA Chandra X-ray has found and they are still waiting for the results to show the possible occurence of the mysterious cosmic explosion.
