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.

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.
NGC7129: star-forming region & reflection nebula in Cepheus; it is about 3000 ly away; stars in this nebula are very young, about 1 Ma old. The red blobs above & below the nebula are Herbig Haro objects, the result of jets of gas streaming away from young stars in the nebula
Finnish astrophotographer J-P Metsävainio observed IC 1396, making a gorgeous image of it. But he wasn’t satisfied just doing that. He’d been playing with making 3D images for some time, and decided this might be a good opportunity to make a model of the structure of the nebula, and then create an animated GIF of it.
Look close, Stare far away, There you will find beauty. But, first look.
M78 is a section of the cloud just above Orion’s Belt. This image is a combination of 2 views: one in visible light from the Digitized Sky Survey, and the other from the APEX telescope, which can see light in the submillimeter wavelength range. Only cold/cold objects emit at this wavelength - a few degrees above absolute zero. The cold dust is falsely colored and glows orange. The blue material is gas/dust which can be seen in visible light.
