Some 4.5 hours of exposure reveal
Bode’s Galaxy (M81, upper center),
the Cigar Galaxy (M82, below center),
Holmberg 9 (upper right), Arp’s
Loop (lower right of M81), and the
Integrated Flux Nebula (throughout).
The two brightest galaxies lie roughly
12 million light-years away.

THE SILVERY MOON
Stars and moonlit clouds hang over
Joshua Tree National Park in California.
The bright star above center is
Sirius (Alpha [α] Canis Majoris). The
constellation Orion lies to its right.
The three stars of the Hunter’s Belt
point to Sirius. Note the reddish
glow of the Orion Nebula (M42).

- A NICE ENCOUNTER
Comet NEOWISE (C/2018 N1) passes
through the region of reflection
nebula IC 4603, which lies in the
constellation Ophiuchus. The bluish
nebulosity makes the green comet
stand out. • Gerald Rhemann - BALL OF SUNS
At magnitude 6.2, globular cluster M3
in the constellation Canes Venatici is
a tough naked-eye catch, although
many observers have observed it that
way. Through a telescope, M3 has a
wide bright center that accounts for
half its width. Surrounding the center
are dozens of stars whose density
gradually decreases as their distance
increases. • Andrew Hayslip/Discovery
