The Elephant Trunk Nebula is an elongated emission nebula IC 1396 in the constellation Cepheus dark globule. Located at a distance of 2,450 light-years, the globule is a condensation of dense gas that is barely surviving the strong ionizing radiation from a nearby massive star. The globule is being compressed by the surrounding ionized gas. The dark globule is seen in silhouette at wavelengths of visible light, illuminated by the light of a bright star to the left of the field of view.
The appearance of filaments globule results are the effects of sculpture competing physical processes. The winds of a massive star, located to the left of the image, producing a circular comprising the 'head' of the globule and aerodynamic tail of an edge dense gas.

A couple of young stars (349 LkHa c LkHa and 349) have been formed from the dense gas has cleared a spherical cavity inside the head of glóbulo.Podemos see the presence of a thick disk of dust around LkHa c 349. such circumstellar discs are the precursors of planetary systems. They are much thicker in the early stages of star formation when the material forming the placental planet (gas and dust) is still present.
Jets and winds of particles emitted from this star are also away the gas and dust environment. Nearly 3,000 light years distant, the relatively faint IC 1396 complex covers in the sky a much larger region than shown here, with an apparent width of more than 10 moons.

NGC7000 Narrow Band



http://www.sky-astrophotography.com/ind ... re&id=1104

NGC 7000 is an emission nebula in the constellation Cygnus, located near Deneb (α Cygni), which is also called the North America Nebula. The dark central region is called The Gulf of Mexico, as in some astronomical plates many years ago it resembled that region of the Earth. NGC 7000 is a large nebula that covers an area equivalent to the full moon, but its low surface brightness makes it normally not visible to the naked eye (however, on a dark night and using a UHC filter it can be seen without optical aid ). The dark area of ​​the center is a very dense region of interstellar material that is in front of the nebula and absorbs the light of the nebula, giving the whole its characteristic shape. The distance that separates us from NGC 7000, or the star responsible for the ionization of the hydrogen produced by the emission of light, is not known precisely. If, as some sources point out, Deneb is the star that illuminates the nebula, the distance from NGC 7000 to Earth would be on the order of 1800 light years.

NGC6960



http://www.sky-astrophotography.com/ind ... re&id=1045

10,000 years ago, before the dawn of the first human writings, a new light was seen in the night sky that was dissipating over the weeks. Today we know that light was a star that exploded and left a colorful expanding cloud called the Veil Nebula. The image above is the west of this nebula technically known as NGC 6960 and less formally as the witch's broom nebula. The gas we see gains in color thanks to the impact of a nearby gas that was already excited. The supernova remnant lies about 1400 light-years away in the constellation of the Swan. The Bruja broom currently occupies about 3 times the angular size of the full moon. The bright blue star 52 Swan is seen with the naked eye from a dark spot (in the middle of the photo), but it has nothing to do with this ancient supernova.

NGC6992



http://www.sky-astrophotography.com/ind ... re&id=1042

The Veil Nebula is a cloud of gas and dust heated and ionized in the constellation Cygnus. It constitutes the visible parts of the Cygnus Loop (W78 or Sharpless 103 radio source), large but relatively weak supernova remnant. The supernova source exploded some 5,000 to 8,000 years ago, and the remains have since expanded to cover an area of about 3 degrees in diameter (about 6 times the diameter, or 36 times the area of the full moon). The distance to the nebula is about 1470 light-years. Analysis of the nebula emissions indicate the presence of oxygen and hydrogen

IC1805 Heart Nebula



http://www.sky-astrophotography.com/ind ... re&id=1046

IC 1805 and IC 1848 are two emission nebulae located in the constellation of Cassiopeia at 7500 light years from the Solar System, in the Perseo spiral arm of the Milky Way. Both make up the stellar association Cassiopeia OB6. Also near IC 1805 are Maffei I and Maffei II, two of the brightest galaxies of the Maffei Group. It has a size of almost 200 light years, and its source of ionization are the stars of the young (1.5 million year old) Melotte 15 open cluster, located inside and have been formed in it.

The Seven Sisters (Pleiades, M45)
Copyright: Sebastiano Recupero

The Pleiades is an open star cluster very close to us, around 440 light years, in the constellation of Taurus. It can be easily spotted to the naked eye from suburban skies. It contains hot and extremely luminous B-type stars that have formed within the last 100 million years and the brightest of them are surrounded by interstellar dust that forms a faint reflection nebulosity that can be seen in long exposure photographs. Astronomers estimate that the cluster will survive for about another 250 million years, after which it will disperse due to the strong winds that comes from these stars and the gravitational interactions with its galactic neighborhood.
