Object: M8
M 8, the Lagoon Nebula, is a giant interstellar gas cloud located 6500 light-years from Earth in the constellation Sagittarius. Measuring 60 light years across, this bright nebula is a naked eye object as observed from dark-sky locations.
This image was taken from the Las Campanas Observatory in Chile, where M 8 is positioned nearly overhead as it transits the meridian during its nocturnal trip across Southern winter skies. Composed as a 2-pane mosaic, the total exposure time for this image was 11 hours 30 minutes.
