The Hidden Galaxy – Now you see it
The Whirlpool Galaxy (M51) – In for Questioning
The unique question mark appearance of M51, its size (77 thousand light years, 90% of Milky Way) proximity to us (only 31 million light years) made it a galaxy of interest for me, so I brought it in for some

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
