ASA N16 f 3,6 Davd Cuc , USA www.sa.nVDB-152 (Complex DUSty regioN iN CepheUS).Van den Bergh 152 is of ten descr ibed as a dusty cur tain or ghost ly appar i t ion , this myster ious ref lect ion nebula is very faintand l ies about 1400 l ight -years away, along the edge of a large molecular c loud. Pockets of cosmic dust in the region block l ightfrom background stars and scat ter l ight f rom the embedded br ight s tar ( top) giving par ts of the nebula a character is t ic blue co lor .

ASA N10 f 3,6 gad Baca, Aus a www.bas.c/baca/as/NgC 6188 (emiSSioN NeBUlA iN ArA).The emiss ion nebula is found near the edge of an otherwise dark large molecular c loud in the southern constel lat ion Ara, about4,000 l ight -years away (the pic ture spans about 300 l ight -years) . Formed in that region only a few mil l ion years ago, the mass iveyoung stars of the embedded Ara OB1 assoc iat ion sculpt the fantast ic shapes and power the nebular glow with s tel lar winds andintense ul t ravio let radiat ion.

ASA N10 f 3,6 gad Baca, Aus a www.bas.c/baca/as/iC 1318 (emiSSioN NeBUlA iN CygNi).This large area of emiss ion nebulos i ty surrounds Sadr (Gamma Cygni) , the br ightest s tar in this photo and the hear t of theconstel lat ion of Cygnus the Swan. Numerous s tar c lusters can also be found embedded in the nebulos i ty . The two sect ions of br ight(yel low) nebulos i ty to lef t of Sadr are cal led the But ter f ly Nebula ( IC 1318); the large area of dark nebulos i ty that separates thetwo halves of the But ter f ly is LDN 889. The smal l open c luster NGC 6910 is just lef t and above of Sadr .

ASA N8 f 3,6 gad rann, Aus a www.assud.aiC 2631 & CeDerBlAD 111 (DArk CloUD Complex iN ChAmAeleoN).This very rare amateur wide f ield image shows both nebulae IC 2631 (to the lef t ) and Ced 111 (to the r ight) . The c louds are par t of the Chamaeleondark c loud complex, the c losest low-mass s tar format ion region to the sun. The complex contains dust that ref lect s the blue l ight of nearby B- typestars , a few pink areas glow where energet ic s tar l ight manages to make hydrogen f luoresce. The c louds l ie 520 l ight -years away.

ASA N10 f 3,6 Ann pz, San www.das.f .u.s/%7eaz/asna_n.iC 1848 (emiSSioN NeBUlA iN CASSiopeiA).In the constel lat ion Cass iopeia you wi l l f ind two br ight emiss ion nebulas nicknamed Hear t and Soul . The Soul Nebula -off ic ia l ly dubbed IC 1848 - shines br ight ly in the red l ight of energized hydrogen. Several young open c lusters of s tarspopulate the image which spans roughly 150 l ight years across . The n ebula is around 6,000 l ight years from ear th.

ASA N10 f 3,8 Ann Fnandz, San www.assuf.c/afnandz/NgC 6992 (SUperNoVA remNANt iN CygNUS).Cataloged as NGC 6992, these glowing f i laments of inters tel lar shocked gas are par t of a larger spher ical supernova remnant known asthe Cygnus Loop or the Vei l Nebula expanding debr is f rom a s tar which exploded over 5,000 years ago. Seen from our perspect iveagainst a r ich Mi lky Way star f ield, the Vei l Nebula is now known to l ie some 1,400 l ight -years away toward the constel lat ion Cygnus.

ASA N12 f 3,6 gad rann, Aus a www.assud.aiC 4628 (emiSSioN NeBUlA iN SCorBiUS).South of Antares, in the tai l of the nebula- r ich constel lat ion Scorpius, l ies emiss ion nebula IC 4628. Nearby hot mass ive s tars - onlymil l ions of years young - radiate into the nebula with invis ible ul t ravio let l ight , s t r ipping elect rons from atoms. The elect rons eventual lyrecombine with the atoms to produce the vis ib le nebular glow. At an est imated dis tance of 6,000 l ight -years , the region shown is about250 l ight -years across .

ASA N10 f 3,6 gad Baca, Aus a www.bas.c/baca/as/NgC 7000 - North AmeriCA NeBUlA (emiSSioN NeBUlA iN CygNUS).This emiss ion nebula is famous par t ly because i t resembles Ear ths cont inent of Nor th Amer ica. To the r ight of the Nor th Amer icaNebula is the less luminous Pel ican Nebula. The two emiss ion nebulae measure about 50 l ight -years across , are located about 1500l ight -years away and are separated by a dark absorpt ion c loud. The nebulae can be seen with binoculars from a dark locat ion.

ASA N12 f 3,6 Wfan p, Ausa www.as- cs.cm 31 - the ANDromeDA gAlAxy (A loCAl groUp gAlAxy).The Andromeda Galaxy is a spiral galaxy approx imately 2,5 Mi l l ion l ight -years away in the direct ion of the constel lat ionAndromeda. I t i s the nearest spiral galaxy to our own galact ic Mi lky Way. In 2006 observat ions by the Spitzer Space Telescoperevealed that M 31 contains one t r i l l ion s tars , more than twice the nu mber of s tars in our own galaxy.

ASA N8 f 3,6 mca man, Swss ://snwa.fasw.c/m 45 - pleiADeS (opeN StAr ClUSter iN tAUrUS).Perhaps the most famous s tar c luster on the sky, the Pleiades can be seen without binoculars from even the depths of a l ight -pol lutedci ty . Also known as the Seven Sis ters and M 45, the Pleiades is one of the br ightest and c losest open s tar c lusters . M 45 contains over3000 stars , i s 13 l ight years across and is about 400 l ight years away from ear th. Quite evident in the above photograph are the blueref lect ion nebulae that surround the br ighter c luster s tars .

ASA N16 f 3,6 Davd Cuc , USA www.sa.nm 78 (reFleCtioN NeBUlA iN orioN).The dark f i lamentary dust not only absorbs l ight , but also ref lect s the l ight of several br ight blue s tars that formed recent ly in thenebula. M 78 is about f ive l ight -years across and l ight of the above image took roughly 1600 years to arr ive at ear th. M 78 belongsto the larger Or ion Molecular C loud Complex that contains the Great Nebula in Or ion and the Horsehead Nebula.

ASA N10 f 3,6 Ann Fnandz, San www.assuf.c/afnandzm 42 - the greAt orioN NeBUlA (DiFFUSe NeBUlA iN orioN).The Or ion Nebula is a dif fuse nebula s i tuated south of Or ions Belt . I t i s one of the br ightest nebulae, and is vis ib le to the nakedeye in the night sky. M 42 is located at a dis tance of 1,344 20 l ight years and is the c losest region of mass ive s tar format ion toEar th. I t i s est imated to be 24 l ight years across .
