Falschfarbendarstellung der Daten, die ALMA bei Beobachtungen der Starburst-Galaxie NGC 253 aufgenommen hat. Die Farbe gibt die Intensität des empfangenen Lichts an, von schwachem Leuchten bei blauer bis hin zu starkem Leuchten bei rötlicher Färbung. Diese und ähnliche Visualisierungen haben den Astronomen dabei geholfen, das Ausströmen von molekularem Wasserstoffgas aus den Sternentstehungsregionen in den Zentralbereichen von NGC 253 nachzuweisen. Das hier gezeigte Bild ist Titelbild der Ausgabe vom 25. Juli 2013 der Fachzeitschrift 'Nature'.
