A map of the quasi-linear reconstruction of the near field, featuring the Hercules galaxy supercluster. The image shows the entangled web of filaments in grey and knots in nuances of red that constitute the cosmic web. Galaxy clusters are shown as yellow spheres.

Now that I have learnt that boosting from other servers are not show in the local timeline, and proper quotation is also disabled indulge me to enhance discoverability by recommending locals some artist's accounts to follow from other servers in no particular order or style:
A tour of Laniakea, one of the biggest structures in the universe

Not everyone on Mastodon may know about my Bright Star Catalogue app. This is a web application that allows you to search for information about any naked eye star from Gaia DR3, Hipparcos and several other sources: https://gruze.org/bsc_app/
Someone asked me for great professional concept/scifi artists to follow on Mastodon. Here are a few:

@Ailantd
@alexconnolly
@badgertracks
@alexriesart
Other artists: don't hesitate to wave in comments. I'll do a better list next week :)

John Wick wrote a TTRPG with that theme. House cats are secretly intelligent, and they protect humans from monsters that humans cannot see.

Did you see how to do two-point perspective with rubber bands?

An interesting idea. I wonder how this would technically be affected by the 3D aspect of space battles vs the relatively 2D field of naval maneuvers (that is, until submarines enter the picture).
But then I think I read something ages ago that said that aspect tends to be neglected in fictional tactics, though I don't remember if it was about space or submarines or maybe even air battles.
(also I'd think that 16th century ships were made mostly of wood, which would surely make flammability a concern... *but* they can't catastrophically decompress either.)
@nyrath
any space drive worth it's weight can turn a ship into a missile, Spaceguard must be on constant watch to make sure traffic doesn't deviate suspiciously off course.
2/ Here's everything I wrote that is available on DriveThruRPG. A lot of these are journals I had articles in, some are freebies, some were written for a flat fee. But the Fantasy Games Unlimited items -- for Space Opera, Daredevils, and Villains & Vigilantes -- earn me a little royalty money. Handy during retirement!
