Planeta Jupiter, arată mai diferit, în lumină infraroșie. Pentru
a înțelege mai bine, mișcările norilor, Planetei Jupiter și
pentru ca, naveta spațială Juno, de la NASA, să înțeleagă că,
Telescopul Spațial Hubble este îndreptat, spre câmpul vizual
regulat, al întregului gigant Jovian. Culorile Planetei Jupiter,
depășesc limitele vizuale, umane și normale, pentru a include,
atât lumina ultravioletă, cât și cea infraroșie. Fotografia
prezentată aici, realizată în anul 2016, cu 3 benzi de lumină, de
tip infraroșie, aproape au fost redistribuite, în format digital,
într-o fotografie colorată, cartografiată. Jupiter, apare diferit
în infraroșu - parțial, deoarece, cantitatea de lumină solară,
reflectată în spate este distinctă, astfel, oferind diferite
înălțimi ale norilor și latitudini diferite. Cu toate acestea,
rămân multe trăsături familiare, ale lui Jupiter, inclusiv zonele
luminoase și centurile întunecate, care circulă pe Planeta
Jupiter, din apropierea ecuatorului. Marele punct roșu, din partea
stânga jos și sistemele de furtuni, cu șirul de perle, la Sud, de
Marea Pată Roșie. Stâlpii strălucesc, pentru că, înălțimea de
altitudine ridicată este alimentată, de particulele încărcate,
din magnetosfera lui Jupiter. Naveta spațială Juno, a finalizat
acum, cea de a zecea misiune orbitală, dintr-un număr total de 12
misiuni orbitale, științifice și care au fost planificate, pentru
cercetarea Planetei Jupiter și continuă să înregistreze date,
care astfel, ajută omenirea, să înțeleagă, nu numai vremea pe
Jupiter, ci și ce se află sub norii groși, ai lui Jupiter.</span></span>

<span style="font-family: Georgia,"Times New Roman",serif;"><span lang="ro-RO">Explicație:
Ce s-a întâmplat, cu partea superioară a Soarelui ? Săptămâna
trecută, părți ale emisferei sudice, a Planetei noastre Pământ,
au trecut printr-o eclipsă parțială, a Soarelui, unde Luna,
blochează o parte a Soarelui. Fotografia prezentată, a fost
realizată, spre sfârșitul eclipsei, de pe coasta Uruguay-ului, cu
vedere spre Buenos Aires, din Argentina. Casa de lumină, împodobită
cu insula Farallón este văzută în prim planul fotografiei, iar un
avion este vizibil, doar în partea din stânga, a Soarelui.
Fotografia este de fapt, o combinație digitală, compusă din două
expuneri, consecutive, realizate cu aceeași cameră fotografică,
utilizând aceleași setări, una, realizată cu peisajul și una, cu
Soarele, aflat în depărtare. Următoarea eclipsă, a Soarelui, va
fi vizibilă, de pe Planeta Pământ, când va fi o altă eclipsă
parțială, produsă la jumătatea lunii Iulie și va fi vizibilă,
din anumite părți, ale Australiei de Sud, inclusiv în Tasmania.</span></span>

<span style="font-family: Georgia,"Times New Roman",serif;">Explicație:
Cum s-a ajuns aici ? Știm că, trăim pe o planetă, care orbitează
în jurul unei stele, care la rândul ei, orbitează într-o galaxie,
dar, care a fost procesul de apariție, pentru această formă ?
Pentru a înțelege mai bine, detaliile fotografiei, astrofizicienii
au îmbunătățit faimoasa ilustrație cu simularea, denumită:
Illustris Simulation in IllustrisTNG, acum în prezent, fiind cel mai
sofisticat și complex, model de calculator, al modului în care,
galaxiile au evoluat, în Universul nostru. În mod specific, acest
videoclip, prezintă câmpurile magnetice, de la Universul timpuriu
(red-shift 5), până în ziua de astăzi (red-shift 0). Aici, în
fotografie, culoarea și nuanțele de albastru, reprezintă câmpurile
magnetice, care sunt relativ slabe, în timp ce, culoarea și
nuanțele de alb sunt puternic pronunțate. Aceste câmpuri
magnetice, de tip B sunt compatibile, se potrivesc și sunt strâns
conectate, cu galaxiile și grupurile de galaxii. Pe măsură ce,
începe simularea, o cameră virtuală, înconjoară Universul
virtual, al modelului galactic și digital, denumit pe scurt:
IllustrisTNG, prezentând o regiune tânără, aflată la o distanță
de: 30 milioane de ani lumină, să fie destul de filamentară.
Gravitatea, determină galaxiile, să se formeze și să se îmbine,
așa cum Universul nostru, se extinde și evoluează. În final,
Universul IllustrisTNG simulat este un proces statistic bun, raportat
la Universul nostru, real și actual, deși, apar unele diferențe
interesante: de exemplu, o discrepanță, care implică la rândul
ei, puterea în undele radio, emise de particulele, rapid încărcate.</span></div>

de gaz și cu praf. Această apropiere estetică, a noriilor cosmici
și a vânturilor stelare, prezintă steaua variabilă LL Orionis,
care astfel, interacționează cu fluxul din Nebuloasa Orion. Adrift,
se află în grădina stelară, a Nebuloasei Orion, încă din anii
formațiunii, steaua variabilă LL Orionis, produce un vânt stelar,
care este mai energic, decât vântul stelar, de la propriul nostru
Soare, care este de vârstă mijlocie. Pe măsură ce, vântul
puternic stelar, trece printr-un gaz lent, astfel, se formează un
front de șoc, analog cu valul, în formă de arc, la fel, ca și al
unei bărci, care se deplasează prin apă sau la fel, ca și un
avion, care călătorește la viteză supersonică. Structura mică,
arcantă și grațioasă, din partea de, deasupra și din partea
stângă a centrului este șocul cosmic, al arcului, al stelei
variabile Orionis LL, măsurând aproximativ, o jumătate de an
lumină. Gazul mai lent, ce decurge din clopotul central și cald, al
Nebuloasei Orion este Trapezul, aflat în colțul din partea din
stânga sus, al fotografiei. În 3 dimensiuni, frontul de șoc, al
stelei variabile Orionis LL este în formă de castron, care este cel
mai strălucitor, atunci când este văzut, de-a lungul marginii "de
jos". Această frumoasă fotografie, ca și de pictură este
parte cuprinzătoare, dintr-o viziune mozaică, de dimensiune mare, a
grădinii stelare și foarte complexe, din Nebuloasa Orion, umplută
cu o multitudine de forme fluide, asociate cu formarea stelelor.</span></span><span style="text-decoration: none;">

din timpul nopții, din data de 13 Februarie. Prezenta fotografie
este compusă, dintr-o serie de expuneri digitale, poza monocromă
(cu o singură culoare), amintește de momentul, în care filmul, a
fost alcătuit, doar din cele două culori sensibile, de contrast:
alb și negru. A fost o alegere tradițională, pentru o noapte
înstelată și pentru astro-fotografie. Cu o durată de: două
minute și 4 zeci de secunde, cele 22 de cadre suprapuse, cuprind
ansamblul peisagistic, cu Parcul Central, din New York (Central Park,
from New York). În timp ce, stelele trasează linii luminoase, pe
cerul nopții, în timp ce, norii plutesc și formează modele pe
cer. Trasată de sus, în jos, linia punctată, în scena

bine expuse și prelucrate, extraordinara poză, a fost obținută,
dintr-o cameră digitală, foarte sensibilă. Imaginea digitală, se
compune din: nori colorați și nebuloase întunecate, adâncite în
spațiul cosmic, altfel sunt prea insesizabile, pentru a fi văzute
cu ochiul liber. În partea dreaptă sus, a fotografiei este
Nebuloasa din California (cu seria: alias NGC 1499), care are o formă
recunoscută. Litoralul său, are o lungime de peste 6 zeci de ani
lumină și se află la o distanță aproximativă de 1</span></span><span lang="ro-RO"><span style="text-decoration: none;">'</span></span><span lang="ro-RO"><span style="text-decoration: none;">500
ani lumină. Luminozitatea pronunțată și roșiatică, a
nebuloasei, se datorează atomilor de Hidrogen, ionizați, de la
stelele albastre și luminoase: Xi Persei, aflate chiar sub ea.
Nucleul de jos al centrului, fiind de fapt, cunoscutul roi de stele,
denumit Pleiades și care se află la o distanță de 4 sute de ani
lumină și ocupă un spațiu de 15 ani lumină. Culoarea sa,
albastră și foarte spectaculoasă, se datorează, reflectării
luminii stelelor, prin praful interstelar. Printre altele, mai sunt
și stelele fierbinți, ale Asociației Perseus, cu seria OB2 și
nebuloasele întunecate, adâncite în spațiul cosmic, situate de-a
lungul marginilor, norilor moleculari și masivi: Taur și Perseus.
Emisiile, provenite din moleculele, neobișnuite, care conțin
MonOxid de Carbon, ionizat și pozitiv (având formula chimică CO
+). Moleculele neobișnuite devin fluorescente, în prezența luminii
Soarelui și sunt în mare parte, responsabile de formarea nuanței
de culoare albastră, împreună cu trecerea zgomotoasă, a coamei
remarcabile, a cometei. Atunci, când a fost realizată fotografia,
cometa era la aproximativ 17 minute lumină, de Planeta noastră
Pământ.</span></span><span style="text-decoration: none;"> </span>

Mai întâi, nebuloasa are o dimensiune mare de emisie, numită IC
1805 și arată, privită ca și un întreg, la fel, ca și o inimă
umană. Este o formă potrivită, probabil, pentru renumita „ziuă
a îndrăgostiților”, această inimă, strălucește intens, în
lumină roșie, emisă de cel mai proeminent element: Hidrogenul.
Strălucirea roșie și forma mai mare sunt create de un mic grup de
stele, aproape de centrul nebuloasei. În interiorul nebuloasei, sub
formă de inimă sunt vedetele stelelor tinere, din clopotul deschis,
denumit Melotte 15, care astfel, erodează câțiva stâlpi de praf,
într-un spațiu pitoresc, împreună cu lumina și vânturile lor,
energetice. Roiul stelelor, conține câteva stele strălucitoare,
care sunt de aproape 5 zeci de ori, mai mari, decât masa Soarelui
nostru, multe stele negre, reprezintă doar o fracțiune, din masa
Soarelui nostru și un microquasar absent, care astfel, a fost
expulzat, în urmă, cu o perioadă de timp, de câteva milioane de
ani. Nebuloasa Inimii este situată la o distanță de aproximativ

<span style="font-size: small;"><span style="font-family: Georgia,"Times New Roman",serif;"><span lang="ro-RO"><span style="text-decoration: none;">Explicație:
Săptămâna trecută, o mașină a fost lansată, pe orbita Planetei
noastre Pământ. Masina, creată de oameni și roboți, de pe
Planeta noastră Pământ, a fost lansată de către compania SpaceX,
pentru a demonstra, capacitatea Falcon-ului său, de a lansa naveta
spațială, în Sistemul nostru Solar. Pur și simplu, concepută ca
fiind capricioasă, mașina electrică, a fost considerată un obiect
demonstrativ, mai bun, decât blocurile de beton. Un manechin
îmbrăcat și așezat într-un cărucior, numit Starman, stă pe
scaunul șoferului. Fotografia recomandată, reprezintă un singur
cadru, obținut dintr-un videoclip, realizat de una, din cele 3
camere de filmat, instalate pe mașină. Aceste camere, care au fost
conectate la bateria autovehiculului, nu mai sunt la curent. Mașina,
atașată unei rachete secundare, a părăsit de curând, orbita
Planetei noastre Pământ și va orbita între Soarele, Pământul
nostru și centura de asteroizi, până la nesfârșit sau poate,
până la câteva miliarde de ani, de acum încolo, când Soarele
nostru, se va extinde și se va transforma într-un Gigantic Roșu.
Dacă, se va recupera vreodată, ceea ce a rămas, din mașină, ar
avea posibilitatea de a deveni, o fereastră unică și
reprezentativă, pentru tehnologiile dezvoltate, pe Planeta noastră
Pământ, în timpul secolelor XX și începutul secolului XXI.</span></span><span style="text-decoration: none;">

Pleiades ? Se pare că este Cometa cu seria C / 2016 R2 (denumită
PanSTARRS), dar aici, aparențele sunt înșelătoare. În partea
dreaptă și în depărtarea fotografiei, faimosul roi de stele, al
lui Pleiades este dominat de lumina albastră, a stelelor tinere și
masive. În partea stângă și prin vizitarea Sistemului nostru
Solar, din interior este Cometa PanSTARRS, care este un bloc de
gheață, din Sistemul nostru Solar, din exterior, care în prezent,
călătorește o coadă lungă, formată din ioni, dominată de
lumină albastră, provenită dintr-o abundență, neobișnuit de
mare, alcătuită din monoxid de Carbon ionizat. Cometa PanSTARRS, se
deplasează de fapt, spre partea de sus, a fotografiei și punctele
ei, de coadă ionică sunt situate departe de Soarele nostru, dar
sunt afectate, de un vânt solar și un complex de particule, care se
strecoară, din Soarele nostru. Vizibilă, chiar și printr-un
telescop mic, cometa se estompează, pe măsură ce, se îndepărtează
de Planeta noastră Pământ, chiar și dacă, ajunge la punctul cel
mai apropiat, de Soarele nostru, de la începutul lunii Mai.</span></span><span style="text-decoration: none;">

Australia și Asia. În special, fotografia prezentată, preluată de
la „Mall of Asia”, văzându-se în depărtare „peretele
mării”, a fost surprinsă o fază parțială și eclipsată, a
Soarelui, peste Golful Manila, din Filipine. Ambarcațiuni și
instalații navale sunt vizibile, în siluetă, în prim planul
fotografiei. Farmecul eclipsei și entuziaștii de ceruri, bine
plasați, au capturat multe alte fotografii interesante și
artistice, ale eclipsei solare inelare, care include, printre altele,
filme, măști de umbre, de la eclipsă și inele de foc. În ziua de
Joi, părțile din Soarele nostru, vor deveni din nou, blocate,
pentru un scurt timp, de Lună, din nou vizibile, doar de unii, ca și
o eclipsă parțială a Soarelui. Eclipsa din ziua de Joi, totuși,
va fi vizibilă, doar din anumite părți, din partea sudică a
continentului Americii de Sud și din Antarctica.</span></span><span style="text-decoration: none;">

Nu intrați în panică. Este doar un manechin cu înălbire, care se
numește Starman. Pe măsură ce, semiluna însorită, a Planetei
noastre Pământ, se retrage în depărtare, Starman este așezat
confortabil, la volanul mașinii numite Tesla Roadster, din
fotografia finală, cu încărcătura utilă, care a fost lansată,
de o rachetă spațială, denumită Falcon Heavy, pe data de 6
Februarie. Pe plan internațional, are seria 2018-017A, Mașina Tesla
Roadster și Manechinul Starman sunt îndreptate, spre spațiul
cosmic, dincolo de orbita Planetei Marte. Racheta spațială Falcon
Heavy, cu o lansare reușită, a devenit acum, cea mai puternică
rachetă spațială, aflată în circulație și mai este mașina
electrică, cu numărul 4, lansată de pe Planeta noastră Pământ.
Celelalte 3 mașini electrice, au fost lansate pe Lună, de rachete
spațiale, mai puternice (dar, care nu au fost reutilizabile),
rachete spațiale, de tip Saturn V. Totuși, mașina Tesla Roadster
(roadster - automobil deschis), al manechinului Starman este probabil
a fi, singurul care ar avea posibilitatea de a fi considerat legal,
de a circula pe stradă.</span></span>

Această imagine, care a fost prelucrată în mod complet digital și
compusă în mod creativ, din două eclipse celebre: eclipsa lunară
totală (din partea stângă) a zilei, din data de 31 Ianuarie și
eclipsa totală a Soarelui, din data de 21 August 2017. Luna apare,
aproape de mijlocul total, în ambele eclipse totale, de la spate, la
spate. În eclipsa lunară, suprafața acesteia, rămâne slab
luminată, în umbra întunecată a Planetei noastre Pământ. Dar,
în eclipsa de Soare, Luna este în siluetă, împotriva discului
luminos al Soarelui, în cazul în care, suprafața lunară, altfel
întunecată este doar vizibilă, datorită strălucirii Planetei
noastre Pământ. De asemenea, văzute în perechea de imagini,
lunare și aliniate sunt stele subțiri, pe cerul de noapte, care
înconjoară Luna eclipsată. Detalii uimitoare, ale proeminențelor
și fluxurile coronale, înconjoară Soarele eclipsat. Faza totală,
a marei eclipse americane, din data de 21 August, a durat aproximativ
două minute sau o mai mică durată de timp, pentru locații, aflate
de-a lungul căii de umbră a Lunii. Din partea nocturnă, a Planetei
noastre Pământ, totalitatea pentru Luna superioară, asemănătoare
culorii de sânge albastru, din data de 31 Ianuarie, a durat o
perioadă de timp, cu mult peste o singură oră.</span></span><span style="text-decoration: none;">

August 21</span></a></span></span><span style="text-decoration: none;">,
2017. The Moon appears near mid-totality in both the back-to-back
total eclipses. </span><span style="color: navy;"><span lang="zxx"><a class="western" href="https://www.nasa.gov/content/eclipses-and-transits-overview"><span style="text-decoration: none;">In
the lunar eclipse</span></a></span></span><span style="text-decoration: none;">,
its surface remains faintly illuminated in Earth's dark </span><span style="color: navy;"><span lang="zxx"><a class="western" href="https://apod.nasa.gov/apod/ap180203.html"><span style="text-decoration: none;">reddened
shadow</span></a></span></span><span style="text-decoration: none;">.
But in the solar eclipse the Moon is in silhouette against the Sun's
bright disk, where the otherwise dark lunar surface is just visible
due to </span><span style="color: navy;"><span lang="zxx"><a class="western" href="https://apod.nasa.gov/apod/ap170831.html"><span style="text-decoration: none;">earthshine</span></a></span></span><span style="text-decoration: none;">.
Also seen in the lunar-aligned image pair are faint stars in the
night sky surrounding the eclipsed Moon. Stunning details of
prominences and coronal streamers surround the eclipsed Sun. The
total phase of the Great American Eclipse of August 21 lasted </span><span style="color: navy;"><span lang="zxx"><a class="western" href="https://apod.nasa.gov/apod/ap170922.html"><span style="text-decoration: none;">about
2 minutes</span></a></span></span><span style="text-decoration: none;">
or less for locations along the Moon's shadow path. From planet
Earth's night side, totality for the Super Blue Blood Moon of January
31 lasted </span><span style="color: navy;"><span lang="zxx"><a class="western" href="https://apod.nasa.gov/apod/ap180208.html"><span style="text-decoration: none;">well

<span style="font-family: "georgia" , "times new roman" , serif;"><span lang="ro-RO"><span style="text-decoration: none;">Explicație:
La data de 31 Ianuarie, o frumoasă eclipsă lunară, s-a bucurat de
toată noaptea, văzută de pe Planeta noastră Pământ, fiind prima
eclipsă, dintre cele 3 eclipse totale și consecutive ale Lunii.
Această fotografie dramatică a timpului, a urmat performanța
cerească, timp de peste 3 ore, într-o serie compusă de expuneri,
din provincia Hebei, din nordul Chinei. Fixat pe un suport, de tip
trepied, aparatul de fotografiat, înregistrează Luna întunecată,
alunecând printr-un cer senin. Prea luminos, chiar înainte și după
eclipsă, traseul în formă de arc de Lună, crește îngustat și
apare în culoarea roșie, în timpul fazei întunecate și totale,
de eclipsă, care a durat un timp de o singură oră și 16 minute.
În unghiul vizual îndepărtat sunt traseele colorate, ale stelelor,
din arcurile concentrice, deasupra și sub ecuatorul ceresc.</span></span><span style="text-decoration: none;">

Frumoasa galaxie, în formă de spirală mare, înregistrată cu
seria NGC 7331 este adesea prezentată, ca și un analog, al Galaxiei
noastre Calea Lactee. Localizată la aproximativ 5 zeci de milioane,
de ani lumină, în Constelația nordică Pegasus, Galaxia cu seria
NGC 7331, a fost recunoscută devreme, ca o nebuloasă, în formă de
spirală și este de fapt, una dintre cele mai strălucite galaxii,
care nu au fost deja incluse, în celebrul catalog, al renumitului
Charles Messier, din secolul al XVIII-lea. Deoarece, discul galaxiei
este înclinat, spre linia noastră de vedere, expunerile lungi
telescopice, formează adesea o fotografie, care evocă, un sentiment
puternic de profunzime. Fotografia a fost obținută de Telescop
Spațial Hubble. Brațele spirale magnifice ale galaxiei, prezintă
benzi închise și întunecate de praf, roiuri luminoase, colorate în
albastru, de stele tinere și masive, împreună cu strălucirea
roșiatică, a regiunilor active, care formează stele. Regiunile
centrale și luminoase, găzduiesc mulțimile de stele, care sunt mai
vechi și mai reci. La fel, ca și în Galaxia noastră Calea Lactee,
o gaură neagră supermasivă, se află în centrul frumoasei
galaxii, în formă de spirală, cu seria NGC 7331.</span></span></div>

Straturile multiple de emisie, apar ciudat de complexe și
neașteptate, având în vedere, aspectul relativ fără chip, al
galaxiei eliptice, văzut în fotografii mai apropiate. Cauza cojilor
este în prezent necunoscută, dar eventual fluxuri de maree sunt
legate de resturile rămase, de la absorbția a numeroase galaxii mai
mici, în ultimele câteva miliarde de ani. În mod alternativ,
învelișurile au posibilitatea de a fi asemănătoare, unor valuri
într-un iaz, unde coliziunea, care este în curs de desfășurare,
cu galaxia spirală, chiar deasupra de Galaxia NGC 474, provoacă
valuri de densitate, prin intermediul gigantului galactic. Indiferent
de cauza reală, fotografia prezentată, evidențiază în mod
dramatic, consensul aflat în creștere, pentru motivul că, minim
unele galaxii eliptice, s-au format în trecutul recent și că,
halo-urile exterioare, ale celor mai multe galaxii mari, nu sunt
chiar netede, dar au diverse complexități, induse de interacțiunile
frecvente, cu acreții, ale unor galaxii mai mici, din apropiere.
Halo-ul propriei noastre Galaxii, Calea Lactee este un exemplu de
complexitate neașteptată. Galaxia cu seria NGC 474, se întinde pe
o suprafață de aproximativ 250 de mii, de ani lumină și se află
la o distanță de aproximativ o sută de milioane, de ani lumină,
față de Constelația Peștilor (Fish - Pisces).</span></span><span style="text-decoration: none;">

Bubble, cu seria NGC 7635 este împinsă de vântul stelar, al stelei
masive BD + 602522, care este vizibilă în culoarea albastră, spre
partea dreaptă a fotografiei, în interiorul nebuloasei. Alături,
totuși, trăiește și un nor molecular, mai obositor, vizibil în
partea dreaptă a fotografiei, în culoarea roșie. În acest spațiu,
o forță irezistibilă, întâlnește într-un mod interesant, un
obiect cosmic. Norul este capabil, să conțină expansiunea gazului
cu bule, dar este influențat de radiația fierbinte, provenită din
steaua centrală, a (nebuloasei) bulei. Radiația, încălzește
regiunile dense, ale norului molecular, care îi provoacă
strălucirea. Nebuloasa cu bule, ilustrată aici este de aproximativ
10 ani lumină și este parte dintr-un complex, mult mai mare, de
stele și cochilii. Nebuloasa cu bule, poate fi văzută, prin
utilizarea unui telescop mic, spre Constelația Reginei din Aethiopia
(Cassiopeia).</span></span></span>

tip neobișnuit de eclipsă a Soarelui, a fost în anul 2012. De
obicei este Luna, Planetei noastre Pământ, care eclipsează
Soarele. În acel an, fiind cel mai neobișnuit, Planeta Venus, a
evidențiat o schimbare. Ca și o eclipsă a Soarelui, de către
Lună, faza Planetei Venus, a devenit o creșcență continuă și
subțire, Venus devenind, din ce în ce, mai bine aliniat, cu
Soarele. În cele din urmă, alinierea a devenit perfectă, iar faza
lui Venus, a scăzut la zero. Punctul întunecat, al Planetei Venus,
a trecut prin vedeta noastră părintească. Situația deosebită, ar
fi posibil, etichetată tehnic, ca și o eclipsă inelară venusiană,
cu un inel, extraordinar de mare, de foc. Imaginați aici, în timpul
ocultirii, Soarele a fost înregistrat, în 3 culori ale luminii
ultraviolete, de către Observatorul Solar Dynamics (denumire, din
limba engleză, </span><span lang="ro-RO">Solar Dynamics</span><span lang="ro-RO">
Observatory - SDO), aflat pe orbita din jurul Planetei noastre
Pământ, cu regiunea întunecată, către partea dreaptă a
fotografiei, care corespunde unei găuri coronale. Câteva ore mai
târziu, când Planeta Venus, continuă pe orbită, apare din nou, o
fază ușoară. Următorul tranzit venusian, de-a lungul Soarelui, va
avea loc în anul 2117.</span></span></span>

circulară, raportată la distanța Lunii este mai ușor de văzut,
în timpul unei eclipse lunare. De fapt, în această fotografie
telescopică și compozită, realizată de pe partea de noapte, a
Planetei noastre Pământ, pe data de 31 Ianuarie, umbra Pământului,
a luat o nuanță roșiatică. Extinderea umbrei, de-a lungul orbitei
lunare este ilustrată, prin alinierea a 3 cadre, obținute chiar
înaintea începerii eclipsei lunare, aproape de mijlocul și
imediat, după terminarea fazei totale, de eclipsă lunară, care a
durat aproximativ 76 de minute. În partea dreaptă, superioară și
mai ușor de văzut, în timpul fazei totale și întunecate a
eclipsei lunare este M44, unul dintre cele mai apropiate roiuri de

este de asemenea, cunoscut și sub numele de Praesepe sau Roiul

</span></span><span style="font-family: Georgia,"Times New Roman",serif;"><span style="font-size: small;"><b>Explanation: </b>The Earth's dark umbral shadow is shaped like
a cone <a href="https://apod.nasa.gov/apod/ap060909.html">extending
into space</a>. Of course its <a href="https://apod.nasa.gov/apod/ap130425.html">circular
cross section</a> at the distance of the Moon is more easily seen
during a lunar eclipse. In fact, in this composite telephoto image
from Earth's night side <a href="https://svs.gsfc.nasa.gov/cgi-bin/details.cgi?aid=4614">on
January 31</a>, the Earth's shadow has taken on a reddish tinge. <a href="http://www.eclipsewise.com/oh/ec2018.html">The
extent</a> of the shadow along the lunar orbit is illustrated by
aligning three frames taken just before the start, near the middle
of, and just after the end of the total eclipse phase that lasted
about 76 minutes. At the upper right and more easily seen during the
eclipse's darker total phase is M44, one of the closest large star
clusters. A mere 600 light-years away, M44 is also known as the
Praesepe or the <a href="https://apod.nasa.gov/apod/ap140222.html">Beehive
Cluster</a>.

Fotografia atmosferică, a unui orizont îndepărtat, se îndreaptă
spre vârfurile înalte ale Trisul-ului, din munții Himalaya, în
India. Fotografia a fost realizată, dintr-o locație îndepărtată,
pe data de 31 Ianuarie 2018, cea mai strălucitoare stea: Sirius,
strălucește în partea dreaptă sus. Luna (Roșie), văzută în
culoare roșie, aflată în creștere, alunecă prin umbra Planetei
noastre Pământ, în timpul eclipsei lunare totale, anticipate, de
seară. Bucurându-se de partea laterală a Planetei noastre Pământ,
eclipsa a fost prima, dintre cele două eclipse lunare totale, în
anul 2018, lansându-se astfel, un an bun, pentru astronomii
lunetiști. Dar, a fost o raritate. Luna eclipsată, a străbătut,
de asemenea, marea perigee apropiată, fiind cel mai apropiat punct
al orbitei sale, în timpul, celei de-a doua fază de Lună Plină, a
Lunii, mai este cunoscută și sub numele de Luna Albastră. Pentru
eclipsa lunară totală, din data de 27 Iulie 2018, Luna Plină, va
fi foarte aproape de apogeu.</span></span></span>

data de 31 Ianuarie 1958, Primul explorator, de tip satelit, denumit
„Explorer”, a fost lansat cu succes, de către Agenția Armatei,
pentru rachete balistice, lansat de pe o rachetă spațială, din
clasa Jupiter-C. Inaugurând epoca explorării spațiului, pentru
Statele Unite ale Americii, Explorer, am fost un satelit, cu
greutatea de 30 de kilograme, care purta instrumentele pentru
măsurarea temperaturilor și a impactului micrometeorit, împreună
cu un alt experiment, proiectat de James A. Van Allen, pentru a
măsura densitatea electronilor și a ionilor din spațiu.
Măsurătorile efectuate de experimentul lui Van Allen, au condus la
o descoperire neașteptată și apoi surprinzătoare, a două benzi
de înfășurare, a Planetei noastre Pământ, cu electroni de mare
energie și ioni prinși în magnetosferă. Acum sunt cunoscute, cu
denumirea de centurile de radiație Van Allen, regiunile sunt situate
în magnetosferă, în partea interioară, dincolo de orbita Planetei
noastre Pământ. Satelitul Explorer, a încetat să mai transmită
date spre noi, cu data de 28 Februarie 1958, dar, a rămas pe orbita
Planetei noastre Pământ, până în luna Martie, din anul 1970.</span></span><span style="text-decoration: none;">

de Planeta noastră Pământ ? Pentru a afla mai bine, Japonia, a
lansat naveta spațială, robotizată, numită Akatsuki, care s-a
aflat pe orbită, în jurul Planetei Venus, la sfârșitul anului
2015, după o aventură neplanificată, cu o durată de 5 ani, în
jurul Sistemului nostru Solar, din zona interioară. Chiar dacă
Akatsuki, a trecut de viața planificată inițial, naveta spațială,
robotizată și instrumentele sale, funcționau atât de bine, încât
o mare parte, din misiunea sa inițială, a fost restabilită. De
asemenea, cunoscut ca „Venus Climate Orbiter”, instrumentele lui
Akatsuki, au investigat date necunoscute, despre planeta soră” a
Planetei noastre Pământ, inclusiv, dacă vulcanii sunt încă
activi, dacă fulgerul are loc în atmosfera densă a ei și de ce
viteza vânturilor, depășește cu mult, viteza de rotație, a
Planetei Venus. În fotografia prezentată aici, obținută de la
aparatul de fotografiat denumit IR2, al lui Akatsuki, partea de
noapte, a lui Venus, arată ca o bandă ecuatorială și pe margini,
cu nori întunecați, absorbind lumina infraroșie, din straturile
mai fierbinți și mai adânci, din atmosfera lui Venus. Formațiunea
portocalie și neagră, strălucitoare, de pe partea dreaptă, sus
este un artificiu digital și fals, care acoperă o parte a feței
planetare, luminoase a zilei. Ziua este cu mult mai strălucitoare,
pe Planeta Venus. Analizele realizate asupra fotografiilor și
datelor obținute, de la naveta spațială, robotizată Akatsuki,
ne-au arătat că, Planeta Venus, are un jet ecuatorial, asemănător
fluxului de jet ecuatorial, al Planetei noastre, Pământ.</span></span><span style="text-decoration: none;">

Păianjenul, va reușii vreodată, să zboare ? Nu, dacă ambele sunt
nebuloase mari, de emisie, spre Constelația Charioteer-ului

fiind IC 417, în timp ce, un nor mai mic, aflat în simularea unui
zbor prin spaţiul cosmic, în partea dreaptă a fotografiei este
catalogat ca fiind NGC 1931 și este atât o nebuloasă de emisie,
cât și o nebuloasă de reflecție. Aflate la o distanță
aproximativă de 10 mii de ani lumină, ambele formaţiuni cosmice,

Dacă, Luna plină, ar dispărea dintr-o dată, ce ați vedea ?
Răspunsul, din timpul eclipsei lunare, totale, în anul 2011, a fost
înregistrat, într-un video dramatic, din Tadjikistan. În timpul
unei eclipse totale de Lună, Planeta noastră Pământ, se
deplasează între Lună și Soare, ceea ce, determină ca Luna, să
se estompeze dramatic. Luna, nu ajunge niciodată întunecată, de
vreme ce, atmosfera Planetei noastre Pământ, reflectă lumina. Așa
cum începe videoclipul, scena poate părea, a fi în timpul zilei și
fiind însorită, dar de fapt este în timpul unei nopţi și lumina
este aprinsă, de la strălucirea Lunii pline. Pe măsură ce, Luna
devine eclipsată și dispare, vântul dispare și el și astfel,
stelele din îndepărtare, pot fi văzute și reflectate, pe
suprafața lacurilor primare. În mod spectaculos, cerul din jurul
Lunii eclipsate, pare dintr-o dată, plin de stele și subliniat de
planul ocupat al Galaxiei noastre, Calea Lactee. Secvența se repetă,
cu o vedere mai apropiată, iar imaginea finală, arată plasarea
Lunii eclipsate, în apropierea nobilelor: Eagle, Swan, Trifid și
Lagoon. Cu o durată de aproape două ore, după ce, eclipsa a
început, Luna izvorăște, din umbra Planetei noastre Pământ, iar
strălucirea plină de lumină, domină din nou, cerul. În ziua de
Miercuri, va avea loc o altă eclipsă lunară, totală, dar, aceasta
se va întâmpla, în timpul unei rare Luni, înfățişată într-o
culoare asemănătoare culorii sângelui şi în acelaşi timp,
foarte albastră.</span></span><span style="text-decoration: none;"> </span></span>
