&lt;b&gt;Descrizione&lt;/b&gt;:&lt;br /&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
M109 ha un&#39;estensione angolare massima di circa 7-8 minuti d&#39;arco, una magnitudine apparente tra 9.5 e 9.6 e un diametro reale di circa 130.000 anni luce. Questa galassia recede da noi alla velocità di 1142 km/s. Una supernova di tipo Ia è esplosa sul bordo sudorientale di questa galassia il 17 marzo 1956; fu catalogata come SN 1956A e raggiunse la magnitudine apparente 12,8. È stata l&#39;unica supernova osservata fra i bracci di questa galassia.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
M109 ha tre galassie satelliti, catalogate come UGC 6923, UGC 6940 and UGC 6969, e probabilmente ve ne sono anche altre più piccole; sono state condotte su queste galassie compresa la primaria un buon numero di osservazioni nella linea di emissione dell&#39;idrogeno. La distribuzione delle regioni H I di M109 è regolare, con un&#39;estensione radiale di basso livello all&#39;esterno del disco galattico, mentre nella regione della barra è presente un buco nella distribuzione dell&#39;idrogeno neutro.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
M109 è la galassia più brillante del Gruppo di M109, un grande gruppo di galassie situato nella costellazione dell&#39;Orsa Maggiore che potrebbe contenere anche più di 50 galassie.&lt;/div&gt;

&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
M106 è un esempio di galassia di Seyfert; la rilevazione di inconsuete emissioni di onde radio e raggi X osservate tramite il radiotelescopio Very Large Baseline Array indica che probabilmente parte della galassia sta precipitando in un buco nero supermassiccio situato nel suo centro: nel nucleo infatti sembra che sia contenuta una massa pari a 36 milioni di masse solari, concentrata in un volume compreso fra 1/24 e 1/12 di anno luce, ossia fra 12000 a 54000 UA.&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
La forma di M106 ricorda quella della Galassia di Andromeda (M31), ma con una diversa inclinazione, in modo che siano così visibili perfettamente tutte le strutture delle nubi di polveri sul piano galattico; i bracci di spirale sono ricchi di regioni H II che nelle immagini si mostrano di colore blu e rosso, a seconda se siano associate o meno ad ammassi di stelle particolarmente calde e luminose. Nel 1981 fra i suoi bracci è apparsa una supernova, classificata come SN 1981K, che raggiunse la sedicesima magnitudine apparente; non essendo stato analizzato lo spettro, non si è mai saputo che tipo di supernova fosse. La distanza della galassia è stimata sui 21-25 milioni di anni luce e la sua massa totale è pari a circa 190 miliardi di masse solari; si allontana da noi alla velocità di 537 km/s.&lt;/div&gt;
&lt;/div&gt;

Visibile anche con modesti strumenti, in telescopi da 200mm di apertura la vista è stupenda: per l&#39;intera lunghezza della galassia è ben evidente una fascia oscura, in posizione leggermente asimmetrica rispetto al nucleo, che la rende straordinariamente simile alla nostra Galassia, alla quale per altro si avvicina sia come forma reale, sia come dimensioni. Dista dalla Via Lattea circa 52 milioni di anni-luce.&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;

La galassia Girasole è una spirale del tipo Sb o Sc, che mostra un irregolare disegno a spirale; apparentemente sembra formare un gruppo fisico con la&amp;nbsp;Galassia girandola, la&amp;nbsp;Galassia Vortice&amp;nbsp;e molte altre galassie minori; potrebbe appartenere al&amp;nbsp;Gruppo di M101&amp;nbsp;(sottogruppo di M51). Il nome proprio&amp;nbsp;&lt;i&gt;girasole&lt;/i&gt;&amp;nbsp;è dovuto al grandissimo numero di segmenti di spirali che circondano il nucleo, ben avvolte attorno ad esso e pervase da un gran numero di nubi di&amp;nbsp;polvere interstellare; la&amp;nbsp;massa&amp;nbsp;totale della galassia sarebbe compresa fra le 80 e le 140 miliardi dimasse solari, con un diametro di 90000&amp;nbsp;anni luce, ossia simile a quello della nostra&amp;nbsp;Via Lattea. La distanza è stimata sui 37 milioni di anni luce e si allontana da noi alla velocità di 580&amp;nbsp;km/s.&lt;br /&gt;Nel maggio del&amp;nbsp;1971&amp;nbsp;è stata osservata fra i suoi bracci una&amp;nbsp;supernova di tipo Ia, che raggiunse la&amp;nbsp;magnitudine apparente&amp;nbsp;11,8.&lt;/div&gt;

&lt;br /&gt;
&lt;b&gt;
Descrizione:&lt;/b&gt;&lt;br /&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
M13 ha una magnitudine apparente di 5,8. Il suo diametro angolare è di 23&#39;, mentre il suo diametro reale è di circa 165 anni luce.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
M13 contiene diverse centinaia di migliaia di stelle, la più brillante delle quali è di magnitudine 11.95. Attorno al suo nucleo, le stelle sono circa 500 volte più concentrate che nei dintorni del sistema solare. L&#39;età di M 13 è stata stimata tra i 12 e i 14 miliardi di anni. La sua distanza dalla Terra è di 23.157 anni luce. Apparendo così luminoso ad una così grande distanza, la sua luminosità reale è elevatissima, oltre 300.000 volte quella del Sole.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
La velocità radiale è di circa 250 km/s in avvicinamento. Questo moto risulta dalla combinazione di tre diverse velocità: la rotazione della Galassia, il moto del Sole nello spazio, e il moto di rivoluzione dell&#39;ammasso attorno al centro galattico.&lt;/div&gt;
&lt;div&gt;

&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;b&gt;Descrizione:&lt;/b&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
M101 è una galassia di notevole estensione se comparata con la Via Lattea;
 secondo diversi studi la sua massa sarebbe di circa 16 miliardi di 
masse solari, ma sembrerebbe essere un valore troppo basso, forse dovuto
 alla bassa luminosità superficiale della galassia; secondo le nuove 
scoperte, che comprendono l&#39;individuazione di regioni H II e una forte velocità di rotazione, la massa di M101 sarebbe compresa fra 100 e 1000 miliardi di masse solari.&lt;sup class=&quot;reference&quot; id=&quot;cite_ref-NASA_Mass_Estimate_5-0&quot;&gt;&lt;/sup&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Un&#39;altra proprietà particolare di questa galassia è la presenza di 
vaste e luminosissime regioni H II, che nelle fotografie raggiunge il 
numero di 3000 unità; queste regioni, in cui ha luogo la formazione stellare, contengono un gran numero di stelle giovani e calde, di colore blu.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Da un lato la galassia presenta un&#39;asimmetria; si crede che si sia 
formata in tempi astronomicamente recenti a causa dell&#39;interazione con 
un&#39;altra galassia, che ne ha deformato i bracci a causa delle potenti 
forze mareali. Inoltre, questo incontro ha amplificato le onde di 
densità del bracci della galassia, che ha causato a sua volta la 
compressione del mezzo interstellare con conseguente aumento dell&#39;attività di formazione stellare.&lt;/div&gt;

&lt;div style=&quot;text-align: justify;&quot;&gt;
M82 è la galassia più grande del Gruppo di M81, un gruppo che conta 34 galassie situate nella costellazione dell&#39;Orsa Maggiore; la distanza media di questo gruppo è di circa 11,7 milioni di anni luce, pari a 3,6 milioni di parsec, rendendolo così uno dei gruppi di galassie più vicini al nostro Gruppo Locale.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
M82 come già visto è in interazione con la vicina Galassia di Bode (M81) e NGC 3077;
 questa interazione ha strappato via alle tre galassie una discreta 
quantità di gas idrogeno, che ora forma delle strutture a filamenti che 
collegano le tre galassie. Inoltre, hanno anche causato la caduta di parte di questo gas sulla Galassia Sigaro e di NGC 3077, causando una grande attività di formazione stellare nei centri di queste due galassie.&lt;/div&gt;

&lt;br /&gt;
&lt;br /&gt;
&lt;b&gt;Descrizione&lt;/b&gt;:&lt;br /&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
La &lt;b&gt;Nebulosa Rosetta&lt;/b&gt;&amp;nbsp; è un&#39;ampia regione H II di forma rozzamente circolare situata ai confini di una nebulosa molecolare gigante, nella costellazione dell&#39;Unicorno.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
La nebulosa ha un diametro angolare di 1,3° e si trova a una distanza di 1600 parsec (circa 5200 anni luce)&lt;sup class=&quot;reference&quot; id=&quot;cite_ref-Phelpsetal2005_2-1&quot;&gt;&lt;/sup&gt; dal sistema solare; ha una dimensione approssimativa di 100 anni luce.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Al centro della Nebulosa Rosetta si trova un brillante ammasso aperto, noto come NGC 2244; le stelle blu dell&#39;ammasso, facenti parte dell&#39;associazione OB nota come Monoceros&amp;nbsp;OB2, emettono radiazione ultravioletta, che eccita il gas della nebulosa portandolo ad emettere luce rossa. Si pensa che il vento stellare del gruppo di stelle O e B
 eserciti pressione sulla nube interstellare causando una compressione, 
seguita dalla formazione di stelle; nella regione infatti sono stati 
osservati molti globuli di Bok, ritenuti sede di formazione stellare.&lt;/div&gt;

&lt;b&gt;
Descrizione :&lt;/b&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
È parte di un turbine di gas e polveri, sagomato come la testa di un cavallo, da qui il 
nome. È una delle nebulose 
maggiormente riconoscibili e note del cielo, anche se è difficile poterla 
osservare visualmente: la sua forma caratteristica si può individuare solo 
attraverso le fotografie dell&#39;area. La prima foto della nebulosa risale al 1888, presa presso l&#39;Harvard College Observatory.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
È talvolta confusa con IC 434, che 
è in realtà la nebulosa a emissione alle sue spalle, di 
colore rosso, originato prevalentemente da idrogeno ionizzato dalla vicina e brillante Sigma Orionis. L&#39;oscurità 
della nebulosa è principalmente causata da polvere densa, anche se la parte più 
bassa del &quot;collo&quot; getta un&#39;ombra sulla sinistra. I flussi di gas che lasciano la 
nebulosa sono incanalati da un forte campo magnetico. Le macchie brillanti alla base 
della nebulosa sono giovani stelle in formazione. La luce della nebulosa Testa di Cavallo impiega circa 1500 
anni per raggiungere la Terra.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;

&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;b&gt;Descrizione:&lt;/b&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Le &lt;b&gt;Pleiadi&lt;/b&gt; (conosciute anche come le &lt;b&gt;Sette sorelle&lt;/b&gt;, la 
&lt;b&gt;Chioccetta&lt;/b&gt; o con la sigla &lt;b&gt;M45&lt;/b&gt; del catalogo di Charles Messier) sono un ammasso aperto visibile 
nella costellazione del Toro. Questo ammasso, piuttosto vicino 
(440 anni luce), conta diverse stelle visibili ad occhio nudo; anche se dagli ambienti cittadini solo 
cinque o sei delle stelle più brillanti sono visibili, da un luogo più buio se 
ne possono contare fino a dodici. Tutte le sue componenti sono circondate da 
leggere nebulose a riflessione, osservabili 
specialmente in fotografie a lunga esposizione prese con telescopi di dimensione ragguardevole.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
I membri visibili delle Pleiadi sono stelle blu o bianche, molto luminose; 
l&#39;ammasso conta in realtà centinaia di altre stelle, la gran parte delle quali 
sono troppo deboli per essere visibili ad occhio nudo. Le Pleiadi sono un 
ammasso giovane, con un&#39;età stimata di circa 100 milioni di anni, e una vita 
prevista di soli altri 250 milioni di anni, a causa della sua bassa densità.&lt;sup class=&quot;reference&quot; id=&quot;cite_ref-seds_4-3&quot;&gt;&lt;a href=&quot;http://www.blogger.com/blogger.g?blogID=4521562965254081511#cite_note-seds-4&quot;&gt;&lt;/a&gt;&lt;/sup&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
A causa della loro brillantezza e vicinanza fra loro, le stelle delle Pleiadi 
sono note dall&#39;antichità: Omero le citava, 
come pure Tolomeo ed 
altri autori dell&#39;età classica. Da 
quando fu noto che le stelle erano corpi celesti simili al Sole, si iniziò ad ipotizzare che fossero in qualche modo 
legate fra loro; con lo studio del moto proprio degli astri e la determinazione delle 
distanze, fu chiaro che le Pleiadi fossero realmente legate gravitazionalmente e 
che avessero un&#39;origine comune.&lt;sup class=&quot;reference&quot; id=&quot;cite_ref-moto_7-0&quot;&gt;&lt;a href=&quot;http://www.blogger.com/blogger.g?blogID=4521562965254081511#cite_note-moto-7&quot;&gt;&lt;/a&gt;&lt;/sup&gt;&lt;/div&gt;

&lt;br /&gt;
&lt;b&gt;Descrizione:&lt;/b&gt;&lt;br /&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
La &lt;b&gt;Galassia di Andromeda&lt;/b&gt; (nota talvolta anche con il vecchio nome 
&lt;b&gt;Grande Nebulosa di Andromeda&lt;/b&gt; o con le sigle di catalogo &lt;b&gt;M&amp;nbsp;31&lt;/b&gt; e 
&lt;b&gt;NGC&amp;nbsp;224&lt;/b&gt;), è una galassia spirale 
gigante facente parte del Gruppo Locale, assieme alla Via Lattea; si trova a circa 2,5 milioni di anni luce dalla 
Terra,in direzione della costellazione boreale di Andromeda, da cui prende il nome. Si 
tratta della galassia spirale di grandi dimensioni più vicina alla nostra 
Galassia; è visibile anche ad occhio nudo e si tratta dell&#39;oggetto più lontano 
visibile da occhi umani senza l&#39;ausilio di strumenti di osservazione.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
La Galassia di Andromeda è la più grande del Gruppo Locale, un gruppo di 
galassie formato dalla Via Lattea, Andromeda e dalla Galassia del 
Triangolo, più circa cinquanta altre galassie minori, molte delle quali satelliti delle 
principali. Sebbene sia la più estesa, sembra che non sia la più massiccia, 
poiché alcuni studi suggeriscono che la Via Lattea contenga più materia oscura e potrebbe 
così essere quella con la massa più grande del gruppo.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Secondo gli studi pubblicati negli anni duemila, derivati dalle osservazioni del Telescopio Spaziale Spitzer, la 
Galassia di Andromeda conterrebbe circa mille miliardi di stelle, un numero 
molto superiore rispetto a quello della nostra Galassia;sulla massa e sul numero di 
stelle ci sono tuttavia opinioni discordanti: alcuni studi indicano un valore di 
massa per la Via Lattea pari all&#39;80% di quello di Andromeda, mentre secondo altri 
studi le due galassie avrebbero delle dimensioni simili fra loro.&lt;sup class=&quot;reference&quot; id=&quot;cite_ref-CfA_6-0&quot;&gt;&lt;a href=&quot;http://www.blogger.com/blogger.g?blogID=4521562965254081511#cite_note-CfA-6&quot;&gt;&lt;/a&gt;&lt;/sup&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Con una magnitudine apparente pari a 4,4, la 
Galassia di Andromeda è uno degli oggetti di Messier più luminosi.&lt;/div&gt;

&lt;span style=&quot;font-family: inherit;&quot;&gt;Si individua verso l&#39;area centrale del grande complesso nebuloso noto come IC 1396, pochi primi d&#39;arco ad ovest dell&#39;ammasso aperto associato alla nebulosa; nonostante le sue ridotte dimensioni, si evidenzia con una discreta facilità, a causa della sua profonda oscurità e per la sua forma, che le ha conferito il soprannome di Proboscide di Elefante. Trovandosi a declinazioni molto settentrionali, si presenta circumpolare dalla gran parte dell&#39;emisfero boreale; tutt&#39;attorno appare circondata da un campo stellare relativamente ricco, e la presenza della nebulosità diffusa di IC 1396 ne risalta ulteriormente la sua natura di nebulosa oscura. La scia scura è interrotta da due stelle di ottava magnitudine.

&lt;span style=&quot;font-family: sans-serif; font-size: x-small;&quot;&gt;&lt;span style=&quot;line-height: 19.1875px;&quot;&gt;La Neblosa Trifida dista circa 5.000 anni luce dalla Terra, venendosi così a trovare nel Braccio del Sagittario, ossia il braccio di spirale immediatamente più interno del nostro. La singola stella massiva visibile al centro è fonte della gran parte dell&#39;illuminazione dell&#39;intera nebulosa; ha un&#39;età stimata di circa 300.000 anni, che ne farebbe la più giovane regione di formazione stellare conosciuta.&lt;/span&gt;&lt;/span&gt;&lt;span style=&quot;font-family: sans-serif; font-size: x-small;&quot;&gt;&lt;span style=&quot;line-height: 19.1875px;&quot;&gt;Le stelle che eccitano i suoi gas sono giganti blu di classe spettrale O e di magnitudine assoluta pari a -5, dell&#39;età di circa 7 milioni di anni; i vari colori sono dati dai diversi elementi: il rosso è tipico dell&#39;idrogeno, mentre l&#39;azzurro dell&#39;ossigeno. Le bande oscure sono invece polveri e gas freddi e non illuminati.&lt;/span&gt;&lt;/span&gt;&lt;span style=&quot;font-family: sans-serif; font-size: x-small;&quot;&gt;&lt;span style=&quot;line-height: 19.1875px;&quot;&gt;Alla lunghezza d&#39;onda di 9,4 cm la nebulosa emette onde radio, causata dalla collisione fra elettroni e protoni, che generano calore fino a raggiungere temperature di 10.000 K. Al centro si trova la stella ADS 10991, una stella tripla con componenti di magnitudine 7,6, 10,7 e 8,7.&lt;/span&gt;&lt;/span&gt;&lt;span style=&quot;font-family: sans-serif; font-size: x-small;&quot;&gt;&lt;span style=&quot;line-height: 19.1875px;&quot;&gt;Il Telescopio Spaziale Hubble ha mostrato nella nube una regione di polvere e gas, una &quot;culla di stelle&quot; piena di embrioni di stelle. Questa nube dista circa 8 anni luce dalla stella centrale della nebulosa. Il piccolo e stretto getto che sporge dalla testa della nube in direzione dell&#39;angolo superiore sinistro è grande circa tre quarti di anno luce (cioè circa 7.000.000.000.000 km). La fonte del getto è un giovanissimo oggetto stellare nascosto dentro la nube. I getti come questo sono i &quot;gas di scarico&quot; della formazione stellare.[4]&lt;/span&gt;&lt;/span&gt;&lt;span style=&quot;font-family: sans-serif; font-size: x-small;&quot;&gt;&lt;span style=&quot;line-height: 19.1875px;&quot;&gt;La foto mostra anche un &quot;gambo&quot; (l&#39;oggetto a forma di dito alla destra del getto). Questo gambo rappresenta un notevole esempio di EGG (Evaporating Gaseous Globules, Globuli Gassosi in Evaporazione) che è sopravvissuto perché sulla sua punta c&#39;è un nodo di gas sufficientemente denso da resistere alla corrosione della potente radiazione stellare.&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;

&lt;b&gt;Descrizione:&lt;/b&gt;&lt;br /&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
NGC 6888 (nota anche come Nebulosa Crescente o con la sigla C 27) è una nebulosa diffusa visibile nella parte meridionale della costellazione del Cigno.&lt;/div&gt;
&lt;br /&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
La nube risplende per riflessione, a seguito dell&#39;energia ricevuta durante l&#39;esplosione della stessa supernova. Nel giro di pochi millenni si prevede che l&#39;oggetto svanirà del tutto, disperdendosi nel mezzo interstellare. I gas della nebulosa appaiono centrati su una stella di Wolf-Rayet (HD 192163), che si trova ora al suo interno; questa stella sarebbe anche la responsabile della nebulosa, che costituirebbe il materiale degli strati più esterni della stella espulsi, che avrebbero poi colliso con altre nebulose creando così la forma che si osserva. Secondo altri studi si tratterebbe invece di un resto di supernova la cui stella progenitrice faceva parte del sistema di HD 192163. La nebulosa si estende nello spazio per una dimensione di circa 16 anni luce.&lt;/div&gt;

&lt;br /&gt;
&lt;strong&gt;Descrizione:&lt;/strong&gt;&lt;br /&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
La nebulosa ricorda un pellicano, a causa di una nebulosa oscura che segna il bordo settentrionale dell&#39;oggetto, facendolo così rassomigliare ad un becco di pellicano; si tratta da un punto di vista astronomico di una nebulosa ad emissione, molto studiata a causa dei fenomeni di formazione stellare che avvengono al suo interno. A causa delle forti dinamiche dei suoi gas, la nebulosa varierà forma relativamente in fretta.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
La Nebulosa Pellicano appartiene allo stesso complesso nebuloso molecolare della Nebulosa Nord America, una regione identificata con la sigla W58 o DR 27; la principale responsabile della ionizzazione dei gas di entrambe le nebulose è nota come 2MASS J205551.25+435224.6; si tratta di una sorgente particolarmente isolata situata oltre la banda oscura di LDN 935, ben visibile nella banda del vicino infrarosso, coincidente con una giovane stella blu di classe spettrale O5V. La sua posizione è particolarmente interessante poiché viene a trovarsi esattamente al centro geometrico del complesso nebuloso.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
La regione di cielo in direzione delle nebulose Nord America e Pellicano presenta un gran numero di oggetti stellari giovani, come è testimoniato dalla presenza di stelle con emissioni nella banda dell&#39;Hα, in particolare stelle T tauri, diverse centinaia di sorgenti infrarosse e oltre quaranta oggetti HH; fra questi, nella Nebulosa Pellicano spicca HH 555, ben evidente sul bordo orientale della parte rappresentante il &quot;becco&quot; del pellicano. HH 555 è un getto bipolare situato sulla punta di una struttura allungata a forma di proboscide che emerge dalla nube, con i getti deviati verso ovest probabilmente a causa dall&#39;espansione della regione H II.&lt;/div&gt;
