M2-9 Wings Of A Butterfly Nebula + William James Quote


Human beings, by changing the inner attitudes of their minds, can change the outer aspects of their lives. ~ William James

Explanation: Are stars better appreciated for their art after they die?  Actually, stars usually create their most artistic displays as they die.  In the case of low-mass stars like our Sun and M2-9 pictured above,  the stars transform themselves from normal stars to white dwarfs by casting off their outer gaseous envelopes. The expended gas frequently forms an impressive display called a planetary nebula that fades gradually over thousand of years. M2-9, a butterfly planetary nebula 2100 light-years away shown in epresentative colors, has wings that tell a strange but incomplete tale. In the center, two stars orbit inside a gaseous disk 10 times the orbit of Pluto. The expelled envelope of the dying star breaks out from the disk creating the bipolar appearance. Much remains unknown about the physical processes that cause planetary nebulae.

    Hey it’s noe from the 130fo. I just bought your book and can’t wait to read it at the 4th of July weekend party at the beach house. While everyone else is going out and getting bombed, I’ll be down at the beach, suntanning, and reading your book. Unless it rains, of course. If it’s anything like the excerpts and the way you write on the forums I know I will be delighted with it. Now, how am I going to get an autograph? LOL!

      Hi! Check your email.

      I put a note at the top of my webpage stating that my paperback is on sale for $12.99 (that includes shipping). I’ve got a box full of them here at the house.
