Messier 1 is easily visible with any telescope, but a 16” or bigger instrument will reveal details within the gases. The debris cloud has been expanding ever since the original explosion, and now it covers an area of space about 10 light-years across. Crab Nebula: A Cosmic ' Generator' Producing Energy at a Rate Equal to 100,000 Suns The Crab Nebula is the remnant of a star that was observed to explode in 1054 A.D. The event was visible to the naked eye for 653 days at night. The Crab Nebula (catalogue designations M1, NGC 1952, Taurus A) is a supernova remnant and pulsar wind nebula in the constellation of Taurus.The common name comes from William Parsons, 3rd Earl of Rosse, who observed the object in 1840 using a 36-inch telescope and produced a drawing that looked somewhat like a crab. Compared to a star's entire history, the visual appearance of a supernova is very brief, perhaps spanning several months, so that the chances of observing one with the naked eye is roughly once in a lifetime. Expert Answer . The “guest star” they observed was actually a supernova explosion, which gave rise to the … By measuring the proper motion of the supernova debris across the plane of the sky over 17 years, this group of astronomers was able to confirm the 1054 explosion date. The known history of supernova observation goes back to 185 AD, when supernova SN 185 appeared; which is the oldest appearance of a supernova recorded by humankind. It was observed as a supernovae in AD 1054. With the advent of satellites that can probe different parts of the electromagnetic spectrum, we have increased our knowledge of this strange object manyfold. The nebula lies at an approximate distance of 6,500 light years from Earth. Astronomers confirm date by comparing photographs taken 17 years apart to study the famous supernova's expansion speed. It is located 6,000 light years away in the constellation of Taurus, and is a strong source of wavelengths from radio waves through gamma ray waves. In 1054, Chinese astronomers took notice of a “guest star” that was, for nearly a month, visible in the daytime sky. Emission lines in the spectrum of the Crab Nebula exhibit a Doppler shift, which indicates that gas in the nebula … It is located 6,000 light years away in the constellation of Taurus, and is a strong source of wavelengths from radio waves through gamma ray waves. Explode definition, to expand with force and noise because of rapid chemical change or decomposition, as gunpowder or nitroglycerine (opposed to implode). The Crab nebula, or M1, was first discovered on July 4, 1054 by Chinese astronomers.However, it was not know to be a supernova and was recorded only as a "guest" star. Astronomers and careful observers saw the supernova in the year 1054. The Earl of Rosse observed the nebula at Birr Castle in the 1840s, and referred to the object as the Crab Nebula because a drawing he made of it looked like a crab.

As a final thought, The Crab Nebula is approximately 4,000 light years away, so if the Chinese saw it explode 1000 years ago, how many years ago did it actually blow up? The distance to the Crab Nebula is about 2000 parsecs. Later Messier ceded the discovery to Beavis when informed of the prior discovery, but Messier was the first to record it in a catalogue.
