Reflection Nebula - This image, centred on the B[e] star HD 87643, beautifully shows the extended nebula of gas & dust that reflects the light from the star. The central star's wind appears to have shaped the nebula, leaving bright, ragged tendrils of gas & dust. A careful investigation seems to indicate that there are regular ejections of matter from the star every 15-50 yrs. The image was taken with the Wide Field Imager on the MPG/ESO 2.2-metre telescope at La Silla.

Star on a #Hubble diet. The star cluster Pismis 24 lies in the core of the large emission nebula NGC 6357 that extends one degree on the sky in the direction of the Scorpius constellation. Part of the nebula is ionised by the youngest (bluest) heavy stars in Pismis 24. The intense ultraviolet radiation from the blazing stars heats the gas surrounding the cluster and creates a bubble in NGC 6357. The presence of these surrounding gas clouds makes probing into the region even harder.
Rho Ophiuchus Nebula Complex This amazing complex of nebulosity revealed on long exposure color photographs is one of the most beautiful areas of the entire night sky. It contains dark nebulae where lanes of obscuring dust hide background stars, blue reflection nebulae where the dust is illuminated by nearby stars and red emission nebulae where the hot hydrogen gas itself is glowing.
