Inside a gigantic cloud of dark molecules and gas is a pair of young stars known as HH46/47. One of these stars is going through a normal but violent phase where its magnetic poles act like railways to channel charged particles away from the star. ALMA observed tons of molecules traveling out of this star along these jets at superfast speeds. These outflows eventually distort and help clear away the cloud from around the star. In this false-color image from ALMA, blue shows jet material heading toward us and red marks the jet particles speeding in the opposite direction.
