Explanation: Big, beautiful spiral galaxy NGC 1055 is a dominant member of a
small galaxy group [8] a mere 60 million light-years away toward the
aquatically intimidating constellation Cetus [9] . Seen edge-on, the island
universe spans over 100,000 light-years, a little larger than our own Milky
Way [10] . The colorful stars in this cosmic close-up of NGC 1055 [11]  are in
the foreground, well within the Milky Way. But the telltale pinkish [12]  star
forming regions are scattered through winding dust lanes along the distant
galaxy's thin disk. With a smattering of even more distant background
galaxies, the deep image also reveals a boxy halo that extends far above and
below the central bluge and disk of NGC 1055. The halo itself is laced with
faint, narrow structures, and could represent the mixed and spread out debris
from [13]  a satellite galaxy disrupted by [14] the larger spiral some 10
billion years ago [15] .
