When a star dies in a violent, fiery death, it spews its innards out across the sky, creating an expanding wave of gas and dust known as a supernova nebula. Arguably, the most famous of these supernova remnants is M1, also called the Crab Nebula, a blob-like patch visible in low-powered binoculars.



The nebula stretches 10 light-years across, though it continues to expand. It lies approximately 6,300 light-years from Earth, in the constellation of Taurus. M1 can be seen with the naked eye in a dark sky, but only barely. A pair of binoculars will turn up a dim patch, while more of the identifying features of the nebula become visible with a low-magnification telescope. A higher-grade, 16-inch telescope will begin to refine more of the nebula. 1968, astronomers in Puerto Rico discovered a pulsing radio source. Determined to be a pulsar, the object is a rapidly-rotating, town-sized star that flashes about 30 times a second. Known as NP0532, or the Crab Pulsar (a remnant of the supernova SN 1054), the neutron star is 100,000 times more energetic than the sun. Though only a few tens of miles across, it shines about as brightly as our nearest sun.

More…Chinese astronomers watching the sky on July 4, 1054, noted the appearance of a new or “guest” star just above the southern horn of Taurus . But knowledge of star-fields was not necessary to spot this surprising visitor — according to records, the, shining six times as brightly as. Those well-versed with the night sky would have been able to see it for 653 days — almost two years — with the naked eye. Other observations of the explosion were recorded by Japanese, Arabic, and Native American stargazer. ( Crab Nebula Album ).If you ask yourself how a supernova explosion looks like as seen from Earth, here is the answer (Betelgeuse explosion footage as seen from Earth):https://youtu.be/dtWeH4-Ugy4 Betelgeuse can break at any time !!! This star is gonna blow! 430 light-years away in the constellation of Orion Betelgeuse is dying. It reached the end of it’s life and currently in the terminal throes of shedding vast bubbles of gas into space. Some scientist believe that Betelgeuse will become a second sun.Have something to say?
