Composite image of the OMC-1 cloud in Orion showing the sometimes explosive nature of star birth, when several young stars were ejected from the region about 500 years ago. The colors in the ALMA data represent the relative Doppler shifting of the millimeter-wavelength light emitted by carbon monoxide gas. The ALMA image is combined with a near infrared image from the Gemini South telescope showing shock waves produced by the explosion.
