I'm working on a huge VR astronomy world for Horizon Worlds and there are many maps (and a Star Cinema, and starships to travel the galaxy, and a meeting space, and a garden, and an observation deck, and the ability to view the sky in many different frequencies, and a cafe and ... much more).
I am redoing my maps to put the galactic centre towards the top for this VR app. Here is a revised 10 pc map.
@galaxy_map Why is #sirus in the center of a red circle? And also Keid system too?
And do you plan to put Black holes, Neutron Stars, #Pulsars and Magnetars in this map too?
@welkin7 Both the Sirius and Keid systems include very hot white dwarfs that although very tiny objects (about the size of the Earth) ionize hydrogen gas for large distances, causing it to glow a faint red.
This map is out to 10 parsecs (about 33 light years). There are several hundred M-type red dwarfs and a number of planets within that distance but no black holes, neutron stars, pulsars or magnetars.
@welkin7 By the way, there are a number of other white dwarfs on the map besides the ones in the Sirius and Keid systems but they are not hot enough to release enough ultra violet radiation to ionize hydrogen gas for a large distance. The Sirius and Keid white dwarfs are unusually hot.
The Sirius B white dwarf is especially hot and is the core of what was once a red giant star that was active during the age of the dinosaurs a few million years ago.
