Object description:
The Antares region - probably the most colorful region
of the sky - offers an impressive impression at different focal lengths. Here a
subregion, west of Antares, the emission nebula Sh2-9, consisting of the
subregions LBN 1101, 1105 and 1106. Left in the image foothills of the
yellowish reflection nebulae around Antares.
The bright star in the
center of the image is Alniyat (sigma Scorpio). It is a blue giant star of
spectral class B1 and it is a periodic variable with low fluctuating amplitude.
Alniyat is a classical representative of the ß-Cephei variable and
probably the system consists of 4 stars. Its distance to the solar system is
about 700 light years. |
