Explanation:
If not the most grand, then this
spiral galaxy is at least one of the most photogenic.
An island universe of about 100 billion stars,
32 million light-years away toward the
constellation Pisces,
M74 presents a
gorgeous face-on view.
Classified as
an Sc galaxy, the
grand design of M74's graceful spiral arms are traced by bright
blue star clusters and dark
cosmic dust lanes.
Constructed from archival images, this
sharp composite is from the
Hubble Space Telescope.
Spanning about 30,000
light-years
across the face of
M74, it includes exposures recording
emission from hydrogen atoms, highlighting
the reddish glow of the galaxy's large
star-forming regions.
