Multi-color View of Young Star 177-341 W in Orion Nebula | ESO
This video shows images of the young stellar object 177-341 W in the Orion Nebula obtained with the Multi Unit Spectroscopic Explorer (MUSE) instrument in the European Southern Observatory’s Very Large Telescope (VLT). Each slice corresponds to a different color or wavelength. At certain wavelengths, corresponding to the emission of elements like hydrogen, nitrogen, oxygen, sulfur, and iron, the nebula shines brightly, revealing intricate structures.
The VLT is equipped with an adaptive optics facility that corrects atmospheric turbulence, making these images sharper than Hubble’s. The system relies on four lasers to create artificial “stars” high up in the atmosphere. Their twinkling is monitored in real time. The lasers have a wavelength of 589 nanometers, and MUSE has a special filter that blocks the light around that wavelength, as shown in the video, so that the lasers do not contaminate the scientific data.
