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.
Glowing Nebula Reveals Cosmic Cat's Paw Credit: ESO This new portrait of NGC 6334 (the Cat's Paw Nebula) was created from images taken with the Wide Field Imager instrument at the 2.2-metre MPG/ESO telescope at the La Silla Observatory in Chile, combining images taken through blue, green and red filters, as well as a special filter designed to let through the light of glowing hydrogen.
This is a deep image of the Sword of Orion - the three stars that make up the weapon hanging off the belt of this famous celestial hunter. The image showcases the amazing mix of physical and optical processes including atomic emission, Rayleigh scattering, reflection and absorbtion of light, that go on in this star forming region to create this kaleidescope of colours and details.
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.
Image Credit & Copyright: César Blanco González The Orion Nebula spans about 40 light years and is located about 1500 light years away in the same spiral arm of our Galaxy as the Sun. The Great Nebula in Orion can be found with the unaided eye just below and to the left of the easily identifiable belt of three stars in the popular constellation Orion. The above image shows the nebula in three colors specifically emitted by hydrogen, oxygen, and sulfur gas.
This image of the region surrounding the reflection nebula Messier 78, just to the north of Orion’s belt, shows clouds of cosmic dust threaded through the nebula like a string of pearls. The submillimetre-wavelength observations, made with the Atacama Pathfinder Experiment (APEX) telescope and shown here in orange, use the heat glow of interstellar dust grains to show astronomers where new stars are being formed. They are overlaid on a view of the region in visible light.
Central area of the Milky Way galaxy, released by astronomers at the European Southern Observatory's Paranal Observatory in Chile. The photo shows 84 million stars in an image measuring 108,500×81,500, which contains nearly 9 billion pixels, and is actually a composite of thousands of individual photographs shot with the observatory's VISTA survey telescope.
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
~~Bubble Nebula ~ NGC 7635, also called the Bubble Nebula is a nebula in the constellation Cassiopeia. It lies close to the direction of the open cluster Messier 52. The "bubble" is created by the stellar wind from a massive hot young central star. The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow | Wikipedia~~
The Cat's Eye Nebula or NGC 6543, is a planetary nebula in the constellation of Draco. Structurally, it is one of the most complex nebulae known, with high-resolution Hubble Space Telescope observations revealing remarkable structures such as knots, jets, bubbles and sinewy arc-like features. In the center of the Cat's Eye there is a bright and hot star; around 1000 years ago this star lost its outer envelope, producing the nebula.---Wikipedia
