Caption: A combination of radio and visible light imaged with the Atacama Large Millimeter/submillimeter Array (ALMA) and European Southern Observatory's New Technology Telescope (NTT) revealing birth of a star forming the Herbig-Haro object HH 46/47. ALMA observations shown in orange and green unveil the energetic jet from the central protostar otherwise hidden at visible wavelength due to dust obscuration and dense gas. NTT observations in pink and purple highlight the visible light from the jet emitted towards the observer.

Caption: Una combinazione di luce radio e visibile ripresa dall'Atacama Large Millimeter/submillimeter Array (ALMA) e dal New Technology Telescope (NTT) dell'European Southern Observatory rivela la nascita di una stella che sta formando l'oggetto Herbig-Haro HH 46/47. Le osservazioni ALMA in arancione e verde svelano il getto d'energia della proto-stella centrale, altrimenti nascosto alla lunghezza d'onda visibile a causa dell'oscuramento della polvere e del gas denso. Le osservazioni NTT in rosa e viola evidenziano la luce visibile del getto, emessa in direzione dell'osservatore.
