A molecular cloud, discovered by IRAS satellite in 1984, is a type of interstellar cloud with density and size enough to permit the formation of molecules. This image centered at NGC7497 galaxy in Pegasus, the MBM54 molecular cloud can be seen over a 3.5º square field of view. While NGC7497 galaxy lies at 60 milion light years, the MBM54 is located in the "neighborhood" at only 900ly at high galactic latitudes in the Milky Way.

Hodei molekularra (IRAS sateliteak 1984an aurkitua) izar arteko hodei mota bat da non bertan molekulak sortzeko nahikoa dentsitate eta tamaina dituen. Irudiaren erdian NGC7497 galaxia ikus daiteke Pegaso konstelazioan, MBM54 hodei molekularra 3.5 gradu karratu dituen irudi-eremu osoan zehar ikus daiteke. NGC7497 galaxia 60 milioi argi-urtera dagoen bitartean MBM54 hodei molekularra 900 argi-urtera besterik ez dago, gure galaxiako latitude altuetan.
