This image shows the Orion Nebula as observed by Local Volume Mapper, and published in Kreckel et al. 2024 (https://ui.adsabs.harvard.edu/abs/2024A%26A...689A.352K/abstract). Different emission lines (hydrogen, silicon and oxygen) are represented with different colour, tracing the ionisation structure of the nebula, carving a bubble in the surrounding dense gas shown by WISE 12micrometer imaging. The ionized gas emission traces wispy, filamentary structures and dusty eroding clouds and clumps. Figure taken from https://www.sdss.org/dr19/lvm/about/.

This image shows the location of Black Hole Mapper targets on the sky, with each purple point depicting an object. All fields are in the North taken with the Sloan Telescope at Apache Point Observatory in New Mexico, US. Fields in the South by the du Pont Telescope at Las Campanas Observatory will be part of the next data release, DR20. There is a pink blob around right ascension = 9 hours, which are the eFEDS fields (eROSITA Full Equatorial Depth Survey) released in DR18. Figure taken from https://www.sdss.org/dr19/bhm/

The figure is the banner from the SDSS website www.sdss.org. In the middle it has an image of the Milky Way, showing the bulge, disc and dust lanes. On the left we see an stylised version of the Hertzsprung Russel diagram, while on the right the image transforms into the cosmic web. This image showcases the range of science covered by the three mapper programs in SDSS-V.
