NASA's Crab Nebula Image Shows Eerie Glow of a Dead Star Which has a Heart Beating
Astronomers discovered a real "tell-tale heart" in space, 6,500 light-years from Earth. The "heart" is the crushed core of a long-dead star, called a neutron star, which exploded as a supernova and is now still beating with rhythmic precision. Evidence of its heartbeat are rapid-fire, lighthouse-like pulses of energy from the fast-spinning neutron star. The stellar relic is embedded in the center of the Crab Nebula, the expanding, tattered remains of the doomed star. CREDIT NASA and ESA

The star ‘Crab Nebula’ had previously exploded after going supernova but its pulse still beats with rhythmic precision

The NASA Hubble Space Telescope has obtained some very interesting images of the dead star Crab Nebula. It seems the ghoulish looking dead star still has a heartbeat.

The eerily glowing star had gone supernova long ago and exploded but its pulse at the center still beats with rhythmic precision. The crushed core of an exploded star is considered as its heart and often times it is even referred to as a ‘Neutron Star’.

Such a dead star has the same mass as that of a sun but all of it has been squeezed into an ultra-dense sphere. The sphere is only a few miles long but its strength is believed to be a 100 billion times greater than steel, making it a virtual powerhouse. 

The heartbeat of the Crab Nebula was recognized as the dead sphere spins about 30 times per every second. This revelation is believed to be a tremendous dynamo.

The dead star center is also capable of producing a deadly magnetic field which can generate even up to 1 trillion volts. Energetic activity of such a magnitude can lead to the production of wisp-like waves.

These waves in turn form expanding ring of gas which glow due to the radiation likes radio to X-rays. The Hubble telescope took in these gas glows as black-and-white exposures in images.

NASA then added the green hue to the images to give it a Halloween theme. The observation of Crab nebula’s pulse was originally recorded in between January and September 2012.

Crab Nebula is one of the oldest recorded dead stars which went supernova with observations recorded back in 1054 A.D. Nebula is believed to be 6,500 light-years away even from the constellation Taurus.
