Sh2-73 islada ahuleko nebulosa bat da Hercules
(Herkules) konstelazioan, gugandik 650 argi-urtera eta
nahiko latitude galaktiko altuan dagoena.
Oker HII eremu gisa sartu zen Sharpless katalogoan.
Geroago, hodei molekular bat zela aurkitu zen eta Esne
Bideak bere osotasunean argiztatzen duena, beraz, IFNren
(Fluxu Integratuko Nebulosa) eremua da.
Sh2-73 is a dim reflection nebula in the Hercules
constellation being just 650 light-years away and at
relatively high galactic latitude. It was mistakenly
included as HII region in the Sharpless catalog. Later
discovered to be a molecular cloud and illuminated by
the Milky Way as a whole and therefore part of IFN (Integrated
Flux Nebula). |

Hauts fluxus
osatutako nebulosak, gure galaxian dauden altitude
handiko nebulosak dira. Hauts partikulez, hidrogenoz eta
karbono oxidoz osaturik daude bere gehiengoan eta gure
galaxiako izarrek argiztatzen dituzte. Irudia Herensugea
konstelazioan kokatzen da.
Integrated Flux Nebula are high latitude galactic
nebulae in the Milky Way composed mainly of dust
particles, hydrogen and carbon monoxide and are
illuminated by stars in the Milky Way. Imaged here is
the IFN located in Draco constellation.

Coma
Berenice (Berenizeren adatsa) iparraldeko zeruko asterismo
zahar bat da, konstelazioetako bat bezala definitu dena. Leo
eta Boötes (Itzaina) konstelazioen artean dago eta bi
hemisferioetatik ikusten da. Latinez "Bereniceren ilea" esan
nahi du eta Egiptoko Berenice II.a erreginari egiten dio
erreferentzia, bere ile luzea sakrifikatu zuen boto-opari
gisa. Pertsona historiko bati izendatutako konstelazio
bakarra da.
Coma Berenices is an ancient asterism in the northern sky which
has been defined as one of the constellations. Located between
Leo and Boötes, and it is visible in both hemispheres. Its name
means "Berenice's Hair" in Latin and refers to Queen Berenice II
of Egypt, who sacrificed her long hair as a votive offering. It
is the only constellation named for a historic person.

Lynds Bright Nebula
691, Hartz Nagusian dagoen hodei molekularra, gure galaxian
dauden altitude handiko gune trinkoetako bat da. Hodei
mokelularra, izar-arteko hodei mota bat da non bertan molekulak
sortzeko nahikoa dentsitate eta tamaina dituen, gehienetan H2.
MBM 32 hodei molekularra lehenik LBN 691 bezala katalogatua izan
1965an eta ondoren MBM 32 bezala 1985an. Hartz Nagusiko Hodei
Molekular konplexuan kokaturik dago eta bertan lehen aldiz H2CO
eta NH3 konposatu kimikoak antzeman zituzten.
Lynds Bright Nebula 691 (MBM 32) is a molecular cloud in Ursa
Major, a dense core of high galactic cirrus cloud. A molecular
cloud, is a type of interstellar cloud, the density and size of
which permit the formation of molecules, most commonly molecular
hydrogen (H2). The molecular cloud MBM 32 was first catalogued
as LBN 691 by Lynds (1965) and later as MBM32 by MBM (1985). It
is located in the complex known as the Ursa Major cirrus cloud.
This cloud is one of the first cirrus clouds where H2CO and NH3
organic compounds were detected.

Izar
zirkunpolarra, Lurreko latitude jakin batetik ikusita,
zeruko poloetako baten hurbiltasunagatik ez da inoiz
horizontearen azpian sartzen. Izar zirkunpolarrak,
beraz, toki horretatik hurbileneko polorantz begiratuta
ikusten dira gau osoan, urteko gau guztietan.
A circumpolar star is a star that, as viewed from a
given latitude on Earth, never sets below the horizon
due to its apparent proximity to one of the celestial
poles. Circumpolar stars are therefore visible from said
location toward the nearest pole for the entire night on
every night of the year.

Barnard begizta
(Sh2-276) Orion konstelazioan dagoen igortze nebulosa da.
Begiztak arku itxura dauka, gutxi gorabehera Orion nebulosan
(M42) du bere erdigunea eta Orion Hodei Molekularraren zati bat
da.
Irudiaren eremuan, Barnard Begiztan erdigunean dauden LBN976,
LBN982 eta LBN985 nebulosak ikus daitezke.
Barnard's Loop (Sh 2-276) is an emission nebula in the
constellation of Orion. The loop takes the form of a
large arc centered approximately on the Orion Nebula
(M42) and it's part of the Orion Molecular Cloud Complex.
This field contains LBN976, LBN982 and LBN985 which are
located at the center area of the Barnard's Loop.

Taurus Hodei
Molekularra (TMC) Zezena eta Auriga (Gurdizaina) konstelazioetan
aurkitzen den hodei molekularra da. Gugandik, bakarrik 430
argi-urtera kokatzen da, izarrak sortzen ari diren eremu handi
hurbilena izanik. Perseus Hodei Molekularra (Per HM) berriz,
hodei molekular erraldoia da Perseus konstelazioan, 10000 eguzki
masa duen hauts eta gas hodeia gugandik 1000 argi-urtera
kokatzen da.
The Taurus Molecular Cloud (TMC) is a molecular cloud in the
constellations Taurus and Auriga. At only 430 light-years away
from Earth, the nearest large star formation region and has
hundreds of newly formed stars. The Perseus Molecular Cloud (Per
MCld) is a giant molecular cloud in the constellation of Perseus
at 1000 light-years and contains over 10,000 solar masses of gas
and dust. |

Irudi honek SU Cas izar aldakorraren inguruan izar-hautsez
betetako eremua erakusten du Cassiopeia (kasiopea)
konstelazioan.
Bertan izar-hauts kopuru handiak,
nebulosa ilunak eta islada-nebulosa ugari daude. LDN 1355,
LDN1357 eta 1358 nebulosa ilunek "esku laguntzaile" nebulosaren
ikuspegia osatzen dute.
This images
shows a dusty area around SU Cas variable star in the
constellation Cassiopeia. It contains large amount of
dust, dark nebula and some reflection nebula. LDN 1355,
LDN1357 and 1358 formed the view of the "helping hand"
nebula.

Perseus (Pertseo) iparraldeko zeruko konstelazio bat da eta II.
mendeko Ptolomeo astronomoak zerrendatutako 48 konstelazioetako
bat. Nazioarteko Astronomia Elkarteak
(IAU) definitutako 88 konstelazio modernoen artean dago.
Perseus-en inguruan Greziar mitologian oinarritutako konstelazio
ugari daude, Andromeda mendebaldean, Camelopardalis eta
Cassiopeia iparraldean. Perseus-ek ere mugakide ditu Aries,
Taurus baita Auriga eta Triangulum mendebaldean.
Perseus is a
constellation in the northern sky and It is one of the 48
ancient constellations listed by the 2nd-century astronomer
Ptolemy, and among the 88 modern constellations defined by the
International Astronomical Union (IAU. It is located near
several other constellations named after ancient Greek legends
surrounding Perseus, including Andromeda to the west,
Camelopardalis and Cassiopeia to the north. Perseus also is
bordered by Aries, Taurus also Auriga and Triangulum to the west. |
