Our glimpse into Orion with LVM. 108 tiles cover 4 deg × 4 deg (30 pc × 30 pc), producing a total of almost 195 000 spectra. Colors show different emission lines (Hα: orange, [S II]6717+6731: light blue, [O III]5007: magenta) trace the ionization structure of the nebula, and carve a bubble into surrounding dense gas (WISE 12 μm: yellow). The ionized gas emission traces wispy, filamentary structures and dusty eroding clouds and clumps. The iconic Horsehead Nebula sits at the bright filamentary ionization front and photo-disassociation region between the central ionized nebula IC 434 and the dark neighboring molecular cloud Orion B to the east, while channels for escaping radiation are apparent in the north.
