Explanation: NGC 6888, also known as the Crescent Nebula, is a about 25 light-years across blown by winds from its central, bright, massive star. A triumvirate of astroimagers ( Joe, Glenn, Russell) created this sharp portrait of the cosmic bubble. Their telescopic collaboration collected over 30 hours of narrow band image data isolating light from hydrogen and oxygen atoms. The oxygen atoms produce the blue-green hue that seems to enshroud the detailed folds and filaments. Visible within the nebula, NGC 6888's central star is classified as a Wolf-Rayet star (WR 136). The star is shedding its outer envelope in a strong stellar wind, ejecting the equivalent of the Sun's mass every 10,000 years. The nebula's complex structures are likely the result of this strong wind interacting with material ejected in an earlier phase. Burning fuel at a prodigious rate and near the end of its stellar life this star should ultimately go out with a bang in a spectacular supernova explosion. Found in the nebula rich constellation Cygnus, NGC 6888 is about 5,000 light-years away.

Nehemiah 9:6
New International Version
6 You alone are the LORD. You made the heavens, even the highest heavens, and all their starry host, the earth and all that is on it, the seas and all that is in them. You give life to everything, and the multitudes of heaven worship you.

You made the heavens....

Hard to accept that atheists think all this happened by random molecular motion and just happened to turn out this way.

For such majesty and even things like the colors of miles of trees in the autumn, book author and Catholic radio host on EWTN Teresa Tomeo says "It's God showing off again."

So you are saying that the Crescent Nebula is God blowing bubbles...? : )

God is owed all the glory. Seeing such wonders makes me lift up praise to God in my heart.

It’s only 25 light years across. It’s a very tiny whiff of a bubble in space.

This one is a hard one to see visually, but, it can be done with an OIII filter.

Nearby is the star P Cyg. It’s a variable star and when in it’s bright phase, is probably the furthest star you can see naked-eye at 6,000 ly. Everything in the night sky that you can see as a star is closer.
