Die Barnard Objekte / The Barnard Objects
Edward Emerson Barnard
Edward Emerson Barnard, 16. Dezember 1857 - 06. Februar 1923
Er war einer der Pioniere für die Astrofotografie, insbesondere der Milchstraße. Viele seiner Aufnahmen von Emissions- und Dunkelnebeln sind bis heute unübertroffen.
Edward Barnard wurde als Sohn von Reuben Barnard und Elizabeth Jane geb. Haywood geboren. Sein Vater starb vor seiner Geburt, und der Sohn wuchs in ärmlichen Verhältnissen auf. Im Alter von neun Jahren wurde er Helfer in einem Fotostudio und erwies sich als technisch begabt. Als er auf der Straße eine beschädigte Linse fand, baute er damit sein erstes Fernrohr und begann mit Himmelsbeobachtungen.
Barnard war Autodidakt und konnte sich erst 1876 ein 5-Zoll-Teleskop kaufen; die 380 $ waren sein halber Jahresverdienst. Fünf Jahre später entdeckte er seinen ersten Kometen. In den folgenden Jahren war Barnard als Kometensucher so erfolgreich, dass er von den Prämien, die ein Sponsor für (US-amerikanische) Kometenentdeckungen ausgesetzt hatte, ein Haus für sich und seine junge Frau finanzieren konnte. Ein besonderer Fall war der von ihm 1885 entdeckte Komet 1886 II, dessen Bahn sich durch Bahnstörungen von einer langgestreckten Ellipse zu einer Hyperbelbahn wandelte.
Bei einer wissenschaftlichen Tagung lernte er Simon Newcomb kennen, der den wissenshungrigen jungen Mann motivierte, Mathematik zu lernen. Gleichzeitig erhielt er ein Stipendium für ein Studium an der Vanderbilt University, das er mit 30 Jahren abschloss. Danach wurde er 1888 Mitarbeiter am neu eingerichteten Lick-Observatorium mit dem damals weltgrößten 36 Zoll-Riesenteleskop.
1892 beobachtete er eine Nova und registrierte dabei als Erster eine sich ausdehnende Gaswolke. Hieraus leitete er ab, dass es sich um die Explosion eines Sterns handeln müsse. Im selben Jahr entdeckte er den 5. Jupitermond (Amalthea) - die erste Entdeckung eines Jupitermondes seit Galileo Galilei im Jahr 1610 - und gleichzeitig die letzte (?) derartige Entdeckung mittels visueller Beobachtung. Bald unternahm er erste Versuche in der Himmelsfotografie und entdeckte vier weitere kleine Jupitermonde.
1895 wurde Barnard Professor für Astronomie an der Universität Chicago. Zwei Jahre später wechselte er aus fachlichen und persönlichen Gründen zum Yerkes-Observatorium unter George Ellery Hale. Dort waren jedoch die atmosphärischen Bedingungen für seine geplante fotografische Milchstraßen-Durchmusterung nicht so günstig. So versuchte er 1904, die Mittel zu erhalten, um diese Aufnahmen auf dem Mount Wilson zu machen, wo Hale ein Sonnenobservatorium plante. Im Januar 1905 war es soweit: Mit dem Catherine-Bruce - Doppelastrografen mit der 10-Zoll-Optik (?) von John Brashear gelangen ihm die ersten langbelichteten Fotos. Bis zum Spätsommer produzierte er 480 Aufnahmen von hervorragender Qualität und in den Folgejahren insgesamt 4000. Sie wurden die Basis für seine Entdeckung (die er sich mit Max Wolf teilte), dass bestimmte dunkle Gebiete in der Milchstraße nicht Löcher im Sternenschleier sind, sondern im Gegenteil fein verteilte, aber ausgedehnte Staubmassen, die das Licht der dahinter liegenden Sterne absorbieren. In der Folge erstellte er einen Katalog derartiger Dunkelwolken, den Barnard-Katalog.
1916 entdeckte Barnard den schnellsten bekannten Schnellläufer unter den Fixsternen, den „Barnardschen Pfeilstern". Dieser ist bislang mit einer Entfernung von 5,94 Lichtjahren der unserem Sonnensystem zweitnächste Fixstern (nach Alpha Centauri mit 4,22 LJ). Weiters entdeckte er den großen Emissionsnebel, der den Orion-Komplex einhüllt („Barnards Loop"), sowie die nach ihm benannte Barnards Galaxie im Sternbild Schütze, die nahe Zwerggalaxie NGC 6822.

| 8 | 4 | 17 | 50 | +55 14 | ? | Center of a dark, irregular lane about 2.6 degrees long and 22' + or - across; very much like the dark lanes E. of Rho Ophiuchi | 28 3 | Camelopardalis | |
| 9 | 4 | 18 | +55 3 | ? | Dark, irregular vacancy. This is the middle of a great vacancy extending east and west, the continuous part of which is 2.5 degrees long and about .5 degree wide. It really extends in a more or less broken form for about 6 degrees. There is a wide region extending south of it for a couple of degrees, nearly to the star BD +53 750 (magnitude 5.0) whose position is 4h6m58s, N 53 18' (1875.0). To the east it breaks up into more or less separate spots, somewhat resembling those at the east end of the great lane from Rho Ophiuchi, but unlike that lane it does not originate in a larger vacant space or a nebula. Its borders are not so definite as the Rho Ophiuchi lane. It is approximately bounded by the coordinates 3h58m, N54.7 and 4h20m, N54.8. The individual positions of some of the spots are given in the catalogue. | 28 | Camelopardalis | ||
| 10 | 4 | 18 | 41 | +28 16 | 8 | 5 | The brightest part of B 7 | 78 | Taurus |
| 11 | 4 | 26 | 37 | +55 2 | 3 | East end of irregular lane, B 8 | 28 | Camelopardalis | |
| 12 | 4 | 29 | 47 | +54 14 | 24 | 5 | Isolated dark spot SE of B 11; irregularly round with extension E. from the NE side | 28 | Camelopardalis |
| 13 | 4 | 31 | 18 | +54 53 | 11 | 4 | Irregular; irregularly darker inside with a rather sharp, short, narrow extension toward the S. | 28 | Camelopardalis |
| 14 | 4 | 39 | 59 | +25 44 | 3 | ? | Very small, bright nebula; a bright spot in the dark nebula B 22. (Position given in Astrophysical Journal, 49:14, (1919ApJ.49.1B) in error by 10m in right ascension.) | 78 | Taurus |
| 15 | 4 | 31 | 56 | +46 37 | 13 | 5 | Elliptical; diameter 15' x 10' slightly NW and SE. One of the finest examples of a dark object seen against the ordinary sky and away from the Milky Way. The background on which the stars shine is uniform over the entire plate. The object is in a region somewhat larger than itself, where there are relatively few stars, and is black by contrast with the sky alone. It clearly shows the presence of a feeble uniform luminosity in space which, from the appearance of similar objects in widely different parts of the sky, leads to the belief that this feeble illumination of distant space is universal. If this object were seen against the star clouds of the Milky Way it would appear strikingly black. | 42 | Perseus |
| 16 | 4 | 32 | 26 | +46 36 | 5 | Very small; elongated N and S; close to SE edge of B 15 | 42 | Perseus | |
| 17 | 4 | 32 | 30 | +46 31 | 5 | Very small; elongated N and S; close to E edge of B 15 | 42 | Perseus | |
| 18 | 4 | 31 | 13 | +24 21 | 60 | 5 | Group of dark spots | 78 | Taurus |
| 19 | 4 | 33 | +26 16 | 60 | ? | Large, indefinite | 78 | Taurus | |
| 20 | 4 | 37 | 4 | +50 58 | 60 | 2 | In S part of larger, relatively vacant area; this is the dark object mentioned by Espin in Monthly Notices, 58, 334, (1898MNRAS..58..334E). It is close north of a small group of faint stars and is 6' or 8' in diameter. In a somewhat larger vacant space (sic). It is not so definite as B 15. | 42 | Perseus |
| 21 | 4 | 37 | 57 | +55 21 | 10 | 4 | Indefinite; irregularly round | 28 | Camelopardalis |
| 22 | 4 | 38 | +26 3 | 120 | 4 | Irregular; unequally dark; extended SE and NW; this is a very large region of obscure nebulosity with several darker streaks in it trending northwest. It is partly separated from another starless region lying about 2 degrees to the west and north. Near the middle of the first of these regions is a small luminous nebula with a faint fan-shaped extension for 10' to the northeast (B 14). This is undoubtedly a brighter condensation of the great obscuring mass surrounding it. The position of this small nebula is 4h32m20s, N25 30' (1875.0). | 78 | Taurus | |
| 23 | 4 | 40 | 33 | +29 52 | 5 | 5 | Sharply pointed to the SE; BD +29 728 (magnitude 6.5) in N part | 59 | Taurus |
| 24 | 4 | 42 | 53 | +29 44 | 8 | 5 | Sharply pointed to the S | 59 | Taurus |
| 25 | 4 | 52 | 4 | +46 0 | 8 | 3 | Irregularly round; a good example of a dark or more or less starless region. | 42 | Auriga |
| 26 | 4 | 54 | 38 | +30 37 | 5 | 6 | Irregular; B 26, 27, 28 are close NW of BD +30 741 (mag 6.8), which is involved in feeble nebulosity | 59 | Auriga |
| 27 | 4 | 55 | 8 | +30 33 | 5 | 6 | Irregular | 59 | Auriga |
| 28 | 4 | 55 | 52 | +30 38 | 4 | 6 | Irregular | 59 | Auriga |
| 29 | 5 | 6 | 23 | +31 35 | 10 | 6 | Round; indefinite | 59 | Auriga |
| 30 | 5 | 30 | 16 | +12 46 | 67 | 4 | Large dark area with few stars. There is a nebulous border, .5 degree wide, to the semi-vacant region extending 1 degree east and north from BD +12 803 (magnitude 7.0). Apparently this nebulous border extends many degrees east in a very diffused manner. There is a narrow dark lane extending south from the semi-vacant region, running close west of BD +12 803 to a point nearly 1 degree south of BD +12 801 (mag 6.9). There is a small fan-shaped nebula close north of small star in the position 5h24m30s, +12 3.9' (1875.0). A small strip of nebulosity extends 5' southwest from this star. These two nebulae are probably the brighter parts of a large obscure nebulosity. | 96 | Orion |
| 31 | 5 | 32 | 1 | +12 45 | 30 | 4 | Extended NE and SW; the E. and darkest part of B 30 | 96 | Orion |
| 32 | 5 | 32 | 8 | +12 25 | 3 | Dark projection from S. end of B 31 to the E. | 96 | Orion | |
| 33 | 5 | 40 | 52 | - 2 27 | 4 | 4 | Dark mass, on nebulous strip extending S from Zeta Orionis (see Astrophysical Journal, 38, 500, (1913ApJ....38..496B), and Plate XX) | 116 | Orion |
| 34 | 5 | 43 | 30 | +32 38 | 20 | 4 | Round; starless; indefinite | 59 | Auriga |
| 35 | 5 | 45 | 30 | + 9 3 | 15 | 2 | Elongated E and W, 20'x10', with an extension SE; three small stars N of it. | 96 | Orion |
| 36 | 5 | 49 | + 7 25 | 120 | 4 | Irregular, narrow dark lane, NE and SW. The NE end connects brokenly with B 35. Well shown on Plate 21, Lick Observatory Publications, 11, 1913. | 96 | Orion | |
| 37 | 6 | 32 | +10 28 | 175 | 4 | Irregular, semi-vacant region. This region is abruptly terminated on the S side by the nebulosity extending north from 15 Monocerotis. Its west side ends abruptly at 6h22m15s, +12 26' (1875.0). B 37, 38, and 39 are shown in Plates 28 and 29, Lick Observatory Publications, 11, 1913. | 96 | Monocerus | |
| 38 | 6 | 33 | 41 | +11 4 | 60 | 4 | Irregular vacancy. This seems to refer to a portion of B 37. | 96 | Monocerus |
| 39 | 6 | 38 | 2 | +10 19 | 5 | Small, sharply defined, elongated spot in the nebulosity NW of 15 Monocerotis. | 96 | Monocerus | |
| 40 | 16 | 14 | 38 | -18 58 | 15 | 3 | Diffused dark spot; small star in it. This spot and B 41 are connected with the great nebula about Nu Scorpii and are doubtless denser opaque masses of the nebula. There is a larger dark region belonging to this same system in B 43, from which broken dark lanes somewhat like those from Rho Ophiuchi, though less marked, run eastward for some degrees. | 147 | Scorpius |
| 41 | 16 | 22 | 17 | -19 37 | 45 | 3 | Diffused dark spot | 147 | Scorpius |
| 42 | 16 | 25 | -23 26 | 6 | Great nebula of Mu Ophiuchi; this object is put in the list because, though not wholly dark, it is partly so, and the evident obscuration produced by it puts it in the class for which the catalogue is made. The semi-vacant region in which this, the great nebula of Rho Ophiuchi, lies is about 3.5 degrees in diameter. For references to the visual discovery and early observations of this strange region see Astronomische Nachrichten, 138, 211, 1895; Popular Astronomy 5, 227, 1897; 14, 581, 1906; Lick Observatory Publications, 11, 19, 1913 and Plate 36. | 147 | Ophiuchus | ||
| 43 | 16 | 30 | -19 46 | 4 | Large dark region | 147 | Ophiuchus | ||
| 44 | 16 | 40 | -24 4 | 5 | Dark lane E. from Rho Ophiuchi region. This is the middle of the main part of the great vacant lane that runs east from the region of Rho Ophiuchi. It is about 32' wide and has its beginning in a vacant area in which is the star 22 Scorpii (CD -24 12695, magnitude 5.5). It runs slightly northeast to about 16h40m, -23 40' (1875.0). From this point it extends in a broken chain of dark spots to a little south of B 63. Its total length is therefore about 10 degrees. | 147 | Ophiuchus | ||
| 44a | 16 | 44 | 45 | -40 20 | 5 | 5 | Irregular; sharpest on SE side; CD -40 10662 (mag 9.0) close N. Apparently a real dark object. | 164 | Scorpius |
| 45 | 16 | 46 | -21 35 | 120 | 5 | Rather definite; Extended NE and SW with an irregular projection SW that connects it with the Rho Ophiuchi region. This appears to be a real, dark object. | 146 | Ophiuchus | |
| 46 | 16 | 57 | 12 | -22 43 | 6 | Irregular; definite; a string of small stars in the middle. | 146 | Ophiuchus | |
| 47 | 16 | 59 | 42 | -22 38 | 15 | 5 | Irregular; definite; connected with B 51 by two sharp lanes. | 146 | Ophiuchus |
| 48 | 17 | 1 | -40 41 | 40 | 5 | Fairly well defined; 15' W and N of CD -40 11088 (magnitude 8); seems to be a real object. | 164 | Scorpius | |
| 49 | 17 | 2 | 39 | -33 16 | 3 | Small; close SE of and involving CD -33 11668 (magnitude 9.3). | 164 | Scorpius | |
| 50 | 17 | 2 | 54 | -34 23 | 15 | 6 | Large, irregular dark space; this is an irregular square, sharply defined on the east side and diffused on the west, where there are broken extensions for 30'. The star CD -34 11418 (magnitude 9.8) is near the middle. The stars CD -34 11422 (magnitude 9.8) and -34 11427 (magnitude 9.9) are on the eastern border. | 164 | Scorpius |
| 51 | 17 | 4 | 44 | -22 15 | 20 | 6 | Definite; one of a straggling group toward the eastern end of the dark lane from Rho Ophiuchi. Two irregular, dark lanes run west from it to B 47. | 146 | Ophiuchus |
| 53 | 17 | 6 | -33 35 | 60 | 4 | Large; diffuse; extended N and S by 30'; curved toward the E at N end. | 164 | Scorpius | |
| 54 | 17 | 6 | 34 | -34 15 | 5 | 5 | Small; round; close S. of magnitude 11 star | 164 | Scorpius |
| 55 | 17 | 7 | 33 | -32 0 | 16 | 5 | Irregular; best defined SE.; CD -31 13582 (magnitude 8.9) near the center. | 164 | Scorpius |
| 56 | 17 | 8 | 48 | -32 5 | 3 | 5 | Small; close E of CD -31 13609 (magnitude 9.0). This seems to be a real object. | 164 | Scorpius |
| 57 | 17 | 8 | 22 | -22 49 | 5 | 6 | Elongated NE and SW | 146 | Ophiuchus |
| 58 | 17 | 11 | 12 | -40 24 | 30 | 6 | Slightly extended N and S; a darker core at NE side | 164 | Scorpius |
| 59 | 17 | 11 | 23 | -27 29 | 60 | 5 | Sink hole; at the W end of a wide broken lane from B 78 | 146 | Ophiuchus |
| 60 | 17 | 11 | 51 | -22 26 | 13 | 3 | Curved; extended NE and SW; this and B 57 are the most distinct of a group of dark spots SW of the square end of B 63. | 146 | Ophiuchus |
| 61 | 17 | 14 | 59 | -20 28 | 6 | Small; elongated E and W | 146 | Ophiuchus | |
| 62 | 17 | 16 | 12 | -20 52 | 19 | 6 | Very black in NW part; brightest of three stars in S part is BD -20 4690 (magnitude 9.4). Apparently a real object. | 146 | Ophiuchus |
| 63 | 17 | 16 | -21 28 | 60 | 3 | Large, definite, curved figure, convex to N; the W end abrupt; 97' E and W, 19' wide | 146 | Ophiuchus | |
| 64 | 17 | 17 | 18 | -18 29 | 6 | Cometary; W of M 9; This object is somewhat cometary in form and has a very black core or head that sharply abuts against the thick stratum of stars; from this it spreads out into a large dark area with much dark detail, filling quite a space close southwest of M 9. It thus resembles a dark comet with a dense and well-defined head and diffused widening tail. The position of the head is 17h9m57s, -18 20.6 (1875.0). | 146 | Ophiuchus | |
| 65 | 17 | 19 | 36 | -26 42 | 12 | 6 | Definite; elongated; 12' E and W | 146 | Ophiuchus |
| 66 | 17 | 19 | 57 | -26 53 | 8 | 6 | Definite; extended E and W; CD -26 12082 (magnitude 8.7) 5' from SE edge | 146 | Ophiuchus |
| 67 | 17 | 22 | 30 | -21 53 | 6 | Definite; extended N and S; connects B 65 and 66 | 146 | Ophiuchus | |
| 67a | 17 | 20 | 57 | -26 51 | 13 | 6 | Irregular; definite; BD -21 4591 (magnitude 9.5) in spot, near SE edge | 146 | Ophiuchus |
| 68 | 17 | 22 | 36 | -23 47 | 4 | 6 | Small; irregular; sharply defined; about 20' SW of B 72 | 146 | Ophiuchus |
| 69 | 17 | 22 | 55 | -23 55 | 6 | Very small; irregular; sharply defined; extends N and S 4' | 146 | Ophiuchus | |
| 70 | 17 | 23 | 32 | -24 2 | 4 | 4 | Sharply defined on W side | 146 | Ophiuchus |
| 71 | 17 | 23 | 2 | -24 0 | 1 | ? | Very small; extends 1.25', plus or minus | 146 | Ophiuchus |
| 72 | 17 | 23 | 35 | -23 37 | 6 | S-shaped; this is a striking object. It is a thin, curved black marking, the exact form of the letter S or the figure 5, as the imagination or point of view may dictate. The SE branch runs E for some distance passing close S of the star CD -23 13376 (magnitude 9.1). Its average thickness is about 2'-3'. The position in the catalogue is for the southern part of the figure, or the bottom of the S (see Astrophysical Journal, 49, (1919ApJ....49....1B), Plate III). | 146 | Ophiuchus | |
| 73 | 17 | 24 | 8 | -24 17 | 1 | ? | Very small; extended N and S 4' | 146 | Ophiuchus |
| 74 | 17 | 25 | 8 | -24 12 | 5 | Slightly curved, extending 5' N from CD -24 13325 (magnitude 7.1). Sharpest on W and S sides. | 146 | Ophiuchus | |
| 75 | 17 | 25 | 17 | -22 1 | 5 | Curved and scalloped marking; BD -21 4598 (magnitude 8.3) on N edge (see Astrophysical Journal, 49, Plate II, 1(1919ApJ....49....1B) | 146 | Ophiuchus | |
| 76 | 17 | 25 | -24 24 | 4 | Irregular, narrow black strip, 30' long E and W | 146 | Ophiuchus | ||
| 77 | 17 | 28 | -23 51 | 60 | 3 | Indefinite; connected by a vacant strip with B 78 | 146 | Ophiuchus | |
| 78 | 17 | 32 | -25 35 | 180 | 5 | Very large; CD -26 12152 (magnitude 6.2) S of the middle. This vacant region, with its extension to the west running south of Theta Ophiuchi, is visible to the naked eye (see Popular Astronomy, 14, 580, 1906.) | 146 | Ophiuchus | |
| 79 | 17 | 37 | 23 | -19 36 | 30 | 6 | 30' long SE and NW; narrow; sharply defined | 146 | Ophiuchus |
| 80 | 17 | 37 | 42 | -21 16 | 2 | 3 | Small, definite; 3' x 1', SW and NE; close SE of BD -21 4674 (magnitude 80 8.1). | 146 | Ophiuchus |
| 81 | 17 | 38 | 32 | -23 55 | ? | Very small; diffused; close SW of NGC 6401 | 146 | Ophiuchus | |
| 82 | 17 | 38 | 37 | -23 46 | 3 | Small; angular; well defined; 8' N of NGC 6401 | 146 | Ophiuchus | |
| 83 | 17 | 45 | 18 | -20 0 | 7 | 6 | Irregular; several small stars in it; narrow extension to the S | 146 | Ophiuchus |
| 83a | 17 | 38 | 58 | -24 10 | 4 | 6 | Small; definite; diam. 4', N and S; about 5' SE of BD -19 4698 (magnitude 9.5) | 146 | Ophiuchus |
| 84 | 17 | 46 | 25 | -20 15 | 6 | Irregular looped figure; sharply defined; 22' long E and W; extension from it 20' toward the NW. BD -20 4865 (magnitude 8.2) near W end and BD -20 4860 (magnitude 9.1) near east end. | 146 | Sagittarius | |
| 84a | 17 | 57 | 37 | -17 40 | 16 | 5 | Round; diam. 16', with extension 45' S; BD -17 4967 (magnitude 9.1) in center; perhaps some detail in it | 146 | Sagittarius |

In Monthly Notices, 69 (1908MNRAS..69..117W), Dr. Max Wolf gives a photograph of the nebula, stating that the object was discovered by Dr. Kopff at Heidelberg on October 12, 1908. It is conspicuous on a photograph of mine made with the Willard lens at the Lick Observatory, September 24, 1895, with 5h0m exposure. It is also shown on a photograph of mine made with the Bruce telescope, July 20, 1904, with an exposure of 3h1m. By inadvertence reference to this object was omitted in Lick Observatory Publications, 11, where it is cut out by the matting in Plate 83. | 9 3 | Cepheus | |
