Unique explosion shakes space (VIDEO)

UNITED STATES (OBSERVATORY NEWS) — NASA has reported a powerful thermonuclear explosion in space, writes Science Alert. It could come from a pulsar named SAX J1808.4-3658 (or J1808).

Nasa Neutron’s instrument star Interior Composition Explorer (NICER) has captured X-rays in the form of an intense beam, Science Alert reports. The explosion at its origin would be the most powerful ever detected.

“This explosion is exceptional,” announced in a statement Peter Bult, astrophysicist of the Goddard Space Flight Center who led the research within NASA.

A distant pulsar named SAX J1808.4-3658 (or J1808) would be responsible for this explosion. In 20 seconds, it emitted a quantity of energy equivalent to what the Sun releases in 10 days, says the journal Astrophysical Journal Letters.

Explosion caused by helium

According to the specialists, the thermonuclear explosion was caused by helium which penetrated below the surface of the pulsar before forming a carbon ball.

“Then, helium explodes violently and releases a thermonuclear” fireball “over the entire surface of the pulsar,” says Zaven Arzoumanian, director of NICER.

Pulsars are neutron stars with a very fast rotation frequency.
