Work in Progress…… Read at your own peril, please. In four postings, I believe we have explained why a galaxy takes the spiral form it does using only two ingredients: a bunch of hydrogen and a black hole – all
The Rotten Fish Heat Engine – LDN1251 (Cepheus) in LRGB
There are so many things going on in this image, and in the object itself that I admired from others’ images that I just had to image it myself. Not only is every stage of star formation (from cloud collapse
Winding Problem Solved – Galactic Spiral Structure Part 4
With all the talk about turbulence in Part 3, I am hoping that I didn’t leave with the impression that our galaxy has been left simply chaotic, random, and just a mess as a result. Nothing could be further from
From Torus to Spiral Disk – Galactic Spiral Structure (Part 3)
Where I had hoped to leave you with in Part 2 is the view of a compressed molecular hydrogen cloud with the individual molecules orbiting a black hole with individual molecular angular momentum such that the outward centrifugal force on
Narrowband Light & Filters – A Quick Overview
Ou4 (The Squid Nebula) represents a nice challenge to astrophotography and I find myself going back to it almost annually to try another technique and see if my skill and available processing tools have improved. As part of my new
Torus of Gravity vs Momentum – Galactic Spiral Structure (Part 2)
In Part 1 of our Galactic Spiral Structure story, we discussed two necessary ingredients that we need to bring together to create our galaxy – a relatively small, but substantial piece of condensed matter (a neutron star or black hole
A Bunch of Hydrogen – Galactic Spiral Structure (Part 1)
As my first topic on my website, I wanted to tackle a subject that I believe hasn’t been given due attention elsewhere – why are there spiral galaxies and why do so many galaxies present themselves as spirals? To form
