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.
