Messier 1

Discovered by John Bevis in 1731.
Independently rediscovered by Charles Messier on August 28, 1758.

Messier: M1.

1758 September 12. 1. 5h 20m 02s (80d 00' 33") +21d 45' 17"
Nebula above the southern horn of Taurus, it doesn't contain any star; it is a whitish light, elongated in the shape of a flame of a candle, discovered while observing the comet of 1758. See the chart of that comet, Mem. Acad. of the year 1759, page 188; observed by Dr. Bevis in about 1731. It is reported on the English Celestial Atlas.

[A note in Messier's handwriting added in the margin of his copy of the Connoissance des Temps for 1783 reads:]
This nebula reported on the great English atlas: Seen by Dr Bevis about 1731. according to his letter written to me on 10th June 1771.

[In the Mem. Acad. for 1959, the discovery announce for this nebula is described in the memoir by Delisle on the comet of 1758, Comet De la Nux: Report of M1's discovery by Messier, from: Joseph Nicholas Delisle, 1759. Mémoire sur la comète de 1758 (Memoir on the comet of 1758). Mém. Acad. 1759, p. 154-188]

[p. 165. Discovery of a new nebula.] [On August 28, 1758,] M. Messier discovered there a light almost resembling that of the Comet, but which was even more vivid, whiter & a bit more elongated than the Comet he observed at that time: That comet had appeared to him always almost round in its coma, without an appearance of either a tail or a beard. When the discovery of this new light or nebulous star didn't come to an end of the observations of that morning session, before the sky covered, M. Messier didn't have the time to determine its exact situation with respect to the neighboring stars of the southern horn of Taurus: there will be reported the details of observations, & there will be marked the precise position of that new nebula, its magnitude & the degree of its light compared to that of the Comet of 1758, [..]
[p. 169] [Messier] also has determined exactly on [September] 10 in the morning the position of the nebula, which he had commenced to perceive on August 28 in the morning near the southern horn of Taurus.
[p. 170. Difference of the appearances of the Comet & the new nebula.] [The night of September 11 to 12] .. having compared the appearance or the light of the Comet with that of the nebula of the southern horn of Taurus, one finds there well a difference, the light of the nebula was considerably stronger in this morning than that of the Comet; instead of, like the two preceding days, when the two lights were approaching equality to each other, that of the Comet was always fainter [..]

[A position is given at the end of this paper, on p. 188, as follows:]
Nebulous star discovered on August 28, 1758: Observed Right Ascension: 80d 0' 33" (5h 20m 02s), observed Northern Declination: 21d 45' 27"; observed [ecliptical] Longitude: Gemini 20d 43' 30" (80d 43' 30"), observed Latitude: South 1d 23' 28".

[Mem. Acad. for 1771, p. 435-436 (first Messier catalog)]
The Comet of 1758, on August 28, 1758, was between the horns of Taurus, I discovered above the southern horn, & little distant from the star Zeta of that constellation, a whitish light, elongated in the form of the light of a candle, which didn't contain any star. This light was of almost the same as that of the Comet which I observed at that time; yet it was a bit more vivid, more white & a bit more elongated than that of the Comet which to me had always appeared almost round in its coma, without the appearance of a tail or beard. On September 12 of the same year, I determined the position of this nebula, ist right ascentsion is 80d 0' 33", & its declination 21d 45' 27" north. This nebula is placed [printed] on the chart of the route of the Comet of 1758 (a: Mémoires de l'Académie, year 1759, page 188).

It happened during the observations of this comet [1758 De la Nux], that I discovered a nebula little distant from the star Zeta in the southern horn of Taurus. That nebula is the first of all that I have discovered; of it there is given the position, which has been well to report, referring to the luminosity and extension, with the comet I observed, as one can see in the description which I have given in the Memoir cited by M. de l'Isle [see above].

A nebula without stars.
On November 8 [1774], I looked up the nebula which Mr. Messier has discovered in 1758 according to the French memoirs, situated obliquely north above Zeta at the southern horn of Taurus. I found this object soon with the 7-foot telescope, and in the position listed by Mr. Messier relative to the stars situated closest to it, as the 8th figure shows.

8. Of objects of ambiguous construction
".. But when an object is of such a construction, or at such a distance from us, that the highest power of penetration, which hitherto has been applied to it, leaves it undetermined whether it belongs to the class of nebulae or of stars, it may be called ambiguous. As there is, however, a considerable difference in the ambiguity of such objects, I have arranged 71 of them into the following four collections. [First collection contains M1]
The first contains seven objects that may be supposed to consist of stars, but where the observations hitherto made, of either their appearance or form, leave it undecided into which class they should be placed.
..
The objects in this collection must at present remain ambiguous."

Observations of the 1st of the connoissance des temps.
"1783, 1794, 7 feet [FL] telescope. With 287 [magnification], light without stars."
"1805, 1809, 10 feet telescope. It is resolvable [mottled]. There does not seem any milky nebulosity miced with what I take to be small lucid points."
"1783, 1784, 1809, 20 feet telescope. Very bright, of an irregular figure; full 5 minutes in longest direction. I suspect it to consist of stars."
"1805, large 10 feet telescope. With 220 the diameter is 4'0"; with this power and light it is what must be called resolvable [mottled]."
As all the observations of the large telescopes agree to call this object resolvable, it is properly a cluster of stars at no very great distance beyond their gaging powers; its profundity may therefore be of about the 980th order. It is near the milky way.

[with drawing]
A large nebula, pearly white, about a degree north-west of the star Zeta on the tip of the Bull's southern horn, and on the outskirts of the galaxy. It is of an oval form, with its axis-major trending np to sf, and the brightest portion toward the south. Sir John Herschel registers this in his Catalogue of 1833, as a "barely resolvable cluster;" and figures it with a fair elliptical boundary. He applied his 7, 10, and 20-foot reflectors, and endeavoured to ascertain its relative distance by a modification of their space-penetrating capacities. "As all the observations," he concluded, "of the large telescopes agree to call this object resolvable, it is probably a cluster of stars at no very great distance beyond their gauging powers; its profundity may therefore be of about the 980th order." All this shows the difficulty of what, to my view, is rather a milky nebulosity than a cluster. Thhe powerful telescope constructed by Lord Rosse, however, not only displays the component stars distinctly, but also shows several fringy appendages around, and a deep bifurcation to the south. So do siderial wonders increase with our means of optical practice!
This fine nebula is remarkable as having been discovered by M. Messier - the comet-ferret of Louis XV. - while observing Zeta Tauri and a comet in 1758, when he cought up a "a whitish light, elongated like the flame of a taper." This accident induced him to form his wellknown and useful Catalogue of nebulae and clusters, from the observations of himself, La Caille, and Méchain, in order to prevent astronomers from mistaking any of those for comets; and the List of 103 which he furnished to the public, was considered to have scraped them all together, as far as climate permitted. Whence D'Alembert, speaking of Messier, observed, "on ne peut s'empêcher de regretter qu'un Observateur si exact et si plein de zèle, n'ait pat été placé dans un climate plus heureux." But the progress of astronomy has not depended on climate, as the names Tycho, Römer, Flamsteed, Bradley, Hevelius, Huygens, Schroeter, Olbers, and others of the Iera Phalanx [written in Greek], abundantly testify. Indeed, in the department before us, within twenty years of Messier's publication, the illustrious Sir William Herschel increased the 103 by 2500 new members, in the decried climate of England, thus affording a strong instance how moral causes can control the physical. Piazzi, whose observatory in the Conca d'Oro was to the eye most charmingly situated, was so troubled with a peculiar flickery hot aerial refraction, that one night he exclaimed to me, "Ah, Greenwich is the paradise for an observer!"
It is rather curious, on recollecting that this nebula was the first caught up in seeking the comet of 1759, that it was also a mare's nest to more than one astronomical tyro in August, 1835, when on the look-out for the return of Halley's comet, in the very month in which it had first been seen seventy-five years before: and Zeta Tauri was also the star which served as "pointer", on that interesting advent.

[Phil. Trans. 1844, p. 321-324, drawing on plate XVIII, Fig. 81; on his observation with his 3-feet (36-inch) aperture telescope]
"Fig. 81 is also a cluster; we perceive in this [36-inch telescope], however, a considerable change of appearance; it is no longer an oval resolvable [mottled] Nebula; we see resolvable filaments singularly disposed, springing principally from its southern extremity, and not, as is usual in clusters, irregularly in all directions. Probably greater power would bring out other filaments, and it would then assume the ordinary form of a cluster. It is stubbed with stars, mixed however with a nebulosity probably consisting of stars too minute to be recognized. It is an easy object, and I have shown it to many, and all have been at once struck with its remarkable aspect. Everything in the sketch can be seen under moderately favourable circumstances."

Messier 1. R.A. 5h 28m.5, N. 21d 57'. - The famous "crab nebula" in Taurus. It lies about 1 degree north preceding the star Zeta Tauri. It was first seen by Bevis in 1731. It was again seen by Messier in 1758 while observing the comet of that year, and its rediscovery induced him to form his catalogue of nebulae, to help observers in distinguishing these objects from comets. Sir John Herschel thought it was a cluster of stars at a distance "of about the 980th order," that is 980 times the distance of Capella or Vega. Lord Rosse's telescope is said to have resolved it into stars, but photographs taken by Dr. Roberts in 1892 and 1896 show a very nebulous appearance, and with but little of the "crab-like" form depicted in Lord Rosse's drawing.

M.1. Taurus. Nebula with stars.
Messier's Description: "Nebula above the southern horn of Taurus, it doesn't contain any star; it is a whitish light, elongated in the shape of a flame of a candle, discovered while observing the comet of 1758."
Messier has added, in the margin, a writing which is still very readable: "This nebula is reported in the great english atlas. Seen by the doctor Bévis, in 1731, according to a letter to me from him, of June 10, 1771."
Seen on August 28, and the position determined on September 12 (1758).
It is on lurking on the return of the comet of Halley, of which we have talked more extensively, that Messier did this first discovery, near the star Zeta Tauri.
Observed by John Herschel, Admiral Smyth, d'Arrest, Lord Rosse, Schoenfeld, Lassell, Secchi, Dreyer, Webb, etc., it has received by Lord Rosse the name Crab Nebula. At most, it offers a little resemblance with the crabs which one finds at the shore of the English Channel, irregularly round, and much more like the elongated figure which I have published in Les Étoiles [The Stars], after Lord Rosse. The diverse drawings which have been made of it differ enormously.
This nebula has been photographed often enough at Juvisy since 1902. We have reobserved it in September and October 1917. The photograph reproduced here has been taken by M. Quénisset, on October 18 with a Voigtlender lens (exposed 1h 30m), and the drawing has been made by him on October 15.
Its shape is oval, almost quadrangular, measures 5' 1/2 in length and 3' 1/2 in width. Partly resolvable in more powerful instruments.
