NASA: A Huge X Ray burst detected from outer space
NASA’s NICER (Neutron star Interior Composition Explorer) telescope detected a sudden spike of X Rays. The spike was caused by a massive thermo nuclear flash on the surface of a pulsar.
Pulsar
- A Pulsar is a neutron star whose compact core is left behind when a massive star runs out of fuel. It later collapses under its own weight and explodes.
- A Pulsar spins rapidly and becomes a host to several X-Ray emitting hotspot. As the object spins it produces regular pulses of high-energy radiation.
Findings
- The Explosion releases as much as energy in 20 seconds as that released by the sun in 10 days.
- The Explosion was caused as the hydrogen gas accredited and formed a disk. As the disk becomes denser, the gas ionizes. This traps more and more energy inwards causing the explosion
Significance
Like other astronomical bodies, the sun emits X Rays as well. Therefore, studying about these sources will help to learn about the future of the sun.
