Explanation: Blown by the wind from a massive star, this interstellar apparition has a surprisingly familiar shape. Cataloged as NGC 7635, it is also known simply as The Bubble Nebula. Although it looks delicate, the 7 light-year diameter bubble offers evidence of violent processes at work. Above and left of the Bubble’s center is a hot, O-type star, several hundred thousand times more luminous and some 45 times more massive than the Sun. A fierce stellar wind and intense radiation from that star has blasted out the structure of glowing gas against denser material in a surroundingmolecular cloud. The intriguing Bubble Nebula and associated cloud complex lie a mere 7,100 light-years away toward the boastful constellation Cassiopeia. This sharp, tantalizing view of the cosmic bubble is a composite of Hubble Space Telescope image data from 2016, reprocessed to present the nebula’s intense narrowband emission in an approximate true color scheme.
After being married for 50 years, I took a careful look at my wife one day and said, “Fifty years ago we had a cheap house, a junk car, slept on a sofa bed and watched a 10-inch black and white TV, but I got to sleep with a hot 23-year-old girl every night.
Now, I have a $500,000 home, a $45,000 car, a nice big bed and a large screen TV, but I’m sleeping with a 69-year-old woman. It seems to me that you’re not holding up your side of things.”
My wife is a very reasonable woman. She told me to go out and find a hot 23-year-old girl and she would make sure that I would once again be living in a cheap house, driving a junk car, sleeping on a sofa bed and watching a 10-inch black and white TV.
Aren’t older women great? They really know how to solve an old guy’s problems.
