Messier 81 (NGC 3031 or Bode's Galaxy refering to Johann Elert
Bode who discovered it) is a spiral galaxy about 12 million
light-years away in the constellation Ursa Major while the
Messier 82 (NGC 3034, Cigar Galaxy), about five times more
luminous than the whole Milky Way, is a starburst galaxy near to
M81. NGC 3077 is a small galaxy, also member of the M81 Group.
Despite looking much like an elliptical galaxy, shows wispy
edges and scattered dust clouds that are probably a result of
gravitational interaction with its larger neighbors.
Messier 81 (NGC 3031 edo Boderen Galaxia
bezala ezaguna, Johann Elert Bodek lehen aldiz aurkitu zuenez
bere oroimenez izendatua) galaxia espirala da gugandik 12 milioi
argi-urtera kokatzen delarik Hartz Handia konstelazioan. Messier
82 (NGC 3034 edo Zigarro Galaxia) berriz, Esne Bidea baino bost
aldiz distiratsuagoa da, M81 galaxiatik gertu leherketa
prozesuan dagoen galaxia da. NGC 3077 galaxia txikia da,
M81 galaxia-multzoko kide bat. Nahiz eta galaxia eliptikoa
dirudien izar-hodei barreiatuak ditu bere baitan, bere bizilagun
handiekiko grabitazio iterezioen ondorioa izan daitekela uste
da.
