Hubble Telescope reveals Spinning Core of Crab Nebula
As per a Chinese tale about a millennium old, astronomers from China noticed a bright new star in the constellation Taurus. The most interesting thing about the star was that it was noticed for few weeks, even in daylight. It starts fading after some time and vanished after some years. Astronomers, that time, who didn’t have high-quality telescopes like today’s astronomers, were surprised to see that strange star.
Today, astronomers have succeeded in finding out that the strange astronomical occurrence was a supernova, an explosion of stars that takes place in space. That star disappeared from the astronomers’ sight after puzzling them for several years, but it left a celestial treat that we even see today: the Crab Nebula in the constellation of Taurus.
The nebula, which is known as the first astronomical object with a historical supernova explosion, is some 6,523 light years away from us. Now, the Hubble Space Telescope of NASA has succeeded in getting a view of Crab Nebula’s inner structure. It clicked three high-resolution pictures that provide an insight into the core of the star. The combination of the image showed the star that died a long time ago is still breathing life into nearby gas.
The nebula’s core, which is known as neutron star, rotates about 30 times in one second. “The rapid motion of the material nearest to the star is revealed by the subtle rainbow of colors in this time-lapse image, the rainbow effect being due to the movement of material over the time between one image and another”, as per a statement by NASA.
