The Crab Nebula supernova remnant is the crushed ultra-dense core of a collapsed star. It’s now pulsing like a wildly beating heart at a precise 30 times per second. Due to the neutron star’s rotation, it ejects twin beams of light like a lighthouse.

Core of the Crab Nebula

Even as a child I loved astronomy and stargazing. Is it any wonder I spent 30+ years creating a universe for my characters to play in? Articles like this excite me. I can’t wait to share them with others. I hope you enjoy the beauty as well as the amazing science behind these images.

I compiled notes from my 30 years of worldbuilding and created the Tarthian Empire Companion, an illustrated World-Building Bible and Guide to Writing a Science Fiction Series. The manual provides a look inside the magic that makes my worlds tick. I’m working on additional companion books for different sections of my universe. This book covers one empire. I have dozens. I’d like to create one book that’s dedicated to the immortals in my universe. Pietas and the other Sempervians have a rich history. They are “immortal” because of science, not magic. Genetically designed as superior servants to mankind, they became instead superior masters. The Sempervians have far more background than my books can show.
