Explanation:
This
tall telescopic field of view
looks out along the plane of our Milky Way Galaxy
toward the nebula rich constellation
Cygnus
the Swan.
Popularly called the Tulip Nebula,
the brightest glowing cloud of interstellar gas and dust
above center is also found in the
1959 catalog
by astronomer Stewart Sharpless
as Sh2-101.
Nearly 70 light-years across the complex and beautiful Tulip Nebula
blossoms about 8,000 light-years away, shown in a
Hubble palette image that maps the glow of the
nebula's sulfur, hydrogen, and oxygen ions into
red, green, and blue colors.
Ultraviolet radiation from young energetic stars
at the edge of the Cygnus
OB3 association, including
O star HDE 227018,
ionizes the atoms
and powers the emission from the Tulip Nebula.
Also in the field of view is microquasar
Cygnus X-1,
one of the strongest X-ray sources in planet Earth's sky.
Driven by powerful jets from a black hole accretion disk,
its fainter bluish curved shock front is
only just visible though, directly
above
the cosmic Tulip's petals near the top of the frame.
