The Tulip and Cygnus X-1 | 2022-09-01


Framing a bright emission region,
this telescopic 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 reddish glowing cloud of interstellar gas and dust
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.

Ultraviolet radiation from young energetic stars at the edge of the Cygnus
OB3 association,
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.

Blasted by powerful jets from a
lurking black hole
its fainter bluish curved shock front is
only just visible though, beyond
the cosmic Tulip's petals near the right side of the frame.
