NASA Hubble captures the beating ‘heart’ of Crab Nebula – VIDEO
The Crab Nebula may be one of the most famous and its glow creates a true spectacle, as seen in the latest images captured by NASA’s Hubble Space Telescope.
The telescope revealed the beating heart of one of the most historic remnants of supernova, an exploding star. The inner region sends out clock-like pulses of radiation and tsunamis of charged particles embedded in magnetic fields.
The heart, which is called a neutron star, is the crushed core of the exploded star. Located near the center of the supernova remnant, the heart is about same mass as the sun. Spinning 30 times a second, the neutron star shoots out detectable beams of energy that make it look like it’s pulsating. These interstellar “lighthouse beacons” are invaluable for doing observational experiments on a variety of astronomical phenomena, including measuring gravity waves, according to nasa.gov.
When this “heartbeat” radiation signature was first discovered in 1968, astronomers realized they had discovered a new type of astronomical object.
The first recorded observation of the Crab Nebula can be traced back to 1054 A.D. Chinese astronomers recorded seeing the nebula and considered it a “guest star” appeared in daytime for 23 days. The same star, which appeared to be six times brighter than Venus, was also observed by stargazers living in different countries, including Japan, Middle East and America.
