This Hubble Space Telescope image shows the lenticular galaxy known as Mrk 820. Lenticular galaxies like Mrk 820 are in the transition zone between elliptical and spiral galaxies. A closer look at the appearance of Mrk 820 reveals hints of a spiral structure embedded in a circular halo of stars. Surrounding Mrk 820 in this image is good sampling of other galaxy types, both elliptical and spiral. Most of the smears and specks are distant galaxies, but the prominent bright object at the bottom is a foreground star called TYC 4386-787-1.
