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.

Nice two tone tulip with a stinkbug at the base.

I think I saw Cynus in some old B&W SciFi flicks.

One of the many things we can thank The Almighty for is that there are about six thousand light-years of empty space between Cygnus X-1 and little ol’ us.

Which even at that seems a little too close.

To further your obnoxious thread distraction, add some mocking key words to the thread!

Actually the blue part of the tulip is a woman’s face with a shocked expression.

She has her head tilted about 20 degrees to the left.
Here eyes are dark blue compared to the lighter blue of her forehead.
Her nose is long and narrow and tip has a blush of red.
And the black leftmost antenna of the stink bug ends in her open black mouth.

I’ll call her Tulip Lady.

How many civilizations have been swallowed up in nebula’s as they pass around the galaxy? When they next appear out of the cloud they are living like caveman.

Hey Danny, why don’t you go over the the religious threads and obnoxiously crash them with your humorless garbage?

Be sure to report back.

Cygnus X-1 was the first object detected believed to be a Black Hole.
