Short Object description:
The globular cluster NGC 6441 in the constellation
Scorpius (the Scorpion) is about 38 000 light-years away from Earth. It's
located in the so-called galactic bulge (part of the Milky Way around the
galactic center) on the far side of our home galaxy "behind" the galactic
center. The light of the cluster is clearly reddened due to the interstellar
extinction (E (B-V) = 0.47 mag) and it appears to us in a yellowish tone. The
star cluster forms an interesting pair together with the 3.2 mag star G Scorpii
in between thousands of stars of our Milky Way. The small green nebula just
northwest of G Scorpii is the planetary nebula PK 353.5-04.9.
G Scorpii
is a orange K-giant star with a diameter 16 times of our sun. Distance to our
solar system ist more or less about 126 light years. |

| Unfortunately the seeing and transparency was very bad in that night,
so that NGC 6441 could only be partially resolved into single stars. For the
comparison with the size of the Moon and the position of the planetary nebula
please move the mouse over the image. Click here or the thumbnail image a comparison with the
size of the Moon. |
