Eine mehrjährige Studie der Whirlpoolgalaxie (M 51) hat unser Verständnis der riesigen Molekülwolken verändert, in denen Sterne geboren werden. Die Untersuchung mit einem Katalog von 1500 solcher Wolken zeigt, dass diese offenbar in eine Art diffuser Molekül-Nebelschwaden eingebettet sind, welche die gesamte galaktische Scheibe durchziehen. Der von diesen Nebelschwaden ausgeübte Druck bestimmt, ob sich in den Wolken neue Sterne bilden oder nicht. Geleitet hat die Studie Eva Schinnerer vom Heidelberger Max-Planck-Institut für Astronomie; sie beruht wesentlich auf Daten der Millimeter-Teleskope des Observatoriums IRAM.
Die meisten Sterne einer Galaxie werden im Innern von großen Molekülwolken (giant molecular clouds, GMCs) geboren -
