A compass and scale image titled NGC 1546 HST WFC3/UVIS, against the black background of space. Near top left is a color key with filters: blue (F438W), green (F555W), red (F814W). At center is a Hubble image of the nearby galaxy NGC 1546. The galaxy's orientation gives us a good view of dust lanes from slightly above and backlit by the galaxy's core. This dust absorbs light from the core, reddening it and making the dust appear rusty-brown. The core itself glows brightly in a yellowish light indicating an older population of stars. Brilliant-blue regions of active star formation sparkle through the dust. Several background galaxies also are visible, including an edge-on spiral just to the left of NGC 1546. At bottom right are white compass arrows. The arrow pointing to the 10 o'clock position is labeled E for east; the arrow pointing to the 2 o'clock position is labeled N for north. At bottom left is a scale bar labeled 9,700 light-years over 40 arc seconds.

| About The Image | |
| Color Info | These images are a composite of separate exposures acquired by the WFC3/UVIS instrument on the Hubble Space Telescope. Several filters were used to sample various wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Blue= F438W, Green= F555W, Red= F814W |
