This nebula was also observed by Johann Baptist Cysat in 1618. However, the first detailed study of the Orion Nebula was not performed until 1659 by Christiaan Huygens, who also believed he was the first person to discover this nebulosity. [11] In 1715, Edmond Halley published a list of six nebulae.
The nebula is seen in the visible spectrum at 550 nm (green light). The Crab Nebula was the first astronomical object recognized as being connected to a supernova explosion. [13] In the early twentieth century, the analysis of early photographs of the nebula taken several years apart revealed that it was expanding. Tracing the expansion back ...
As the Orion Nebula was the 42nd object in his list, it became identified as M42. Henry Draper's 1880 photograph of the Orion Nebula, the first ever taken. One of Andrew Ainslie Common's 1883 photographs of the Orion Nebula, the first to show that a long exposure could record new stars and nebulae invisible to the human eye.
The first planetary nebula discovered (though not yet termed as such) was the Dumbbell Nebula in the constellation of Vulpecula.It was observed by Charles Messier on July 12, 1764 and listed as M27 in his catalogue of nebulous objects. [10]
The Crab Nebula is a pulsar wind nebula associated with the 1054 supernova. The known history of supernova observation goes back to 1006 AD. All earlier proposals for supernova observations are speculations with many alternatives. Since the development of the telescope, the field of supernova discovery has expanded to other galaxies. These ...
Pease 1 is a planetary nebula located within the globular cluster M15 33,600 light years away in the constellation Pegasus.It was the first planetary nebula known to exist within a globular cluster when it was discovered in 1928 [2] (for Francis G. Pease), and just four more have been found (in other clusters) since. [1]
SN 1054 is a supernova that was first observed on c. 10 July [O.S. c. 4 July] 1054, and remained visible until c. 12 April [O.S. c. 6 April] 1056. [ 2 ] α The event was recorded in contemporary Chinese astronomy , and references to it are also found in a later (13th-century) Japanese document and in a document from the Islamic world .
The Cat's Eye was the first planetary nebula to be observed with a spectroscope by William Huggins on August 29, 1864. [ 11 ] [ 12 ] Huggins' observations revealed that the nebula's spectrum was non-continuous and made of a few bright emission lines, first indication that planetary nebulae consist of tenuous ionised gas.
