Messier 24 and the large molecular cloud Lynds 291 in the
constellation Sagittarius |
|
Object description:
In our wide-field image, the gigantic, dark molecular
cloud Lynds 291 with the subregions LDN 314
and 315 dominates in the center of the image. In the middle of the molecular
cloud are the emission nebulae IC 1283 and IC 1284, as well as the small blue
reflection nebulae NGC 6589 and NGC 6595. This region was often erroneously
named NGC 6590 in the past. Of this central region we also show
here a higher resolution image, taken with longer focal
length and detailed image description.
To the north (at the top of our
image) lies Messier 24 along with the two
prominent dark nebulae Barnard 92 and
Barnard 93. |

Messier 24 is a visible region of
the Sagittarus spiral arm in view of the central regions of the Milky Way that
is not obscured by dark clouds of gas and dust. The light absorption of gas and
dust in the denser regions of LDN 291 is between 30 and 40 magnitudes. The
distance of M 24 to the solar system is only vaguely known and depends on which
narrow region is studied. The indications are between 10 000 and 15 000 light
years.
B 92 and B 93 were discovered photographically by Edward Barnard
in 1915. Barnard 92 has the popular name "black
hole".
From the
central region we also have a higher resolution image
that we show here.
