A drone shot of four huge telescope tomes on top of a mountain in the middle of the desert. The four domes are identical, all of them cylindrical and metallic, and their sliding doors are open. One of the telescopes is firing four bright laser beams towards the drone. The top of the hill is flat and also hosts other smaller domes and buildings.

#APOD is pretty killer today. B93 = 93rd entry in Barnard's catalogue of dark nebulae.

#Astronomy #astrodon

A nebula appears as a dark jellyfish-like floating ghost against a background of bright interstellar gas and a tapestry of stars.

Even asteroids need friends, so I hooked up the asteroid generator to a point cloud, tweaked a few things, and voila: asteroid fields!

The "merge" parameter doesn't really merge anything; it simply removes the randomization of the noise function per asteroid, so that nearby asteroids get similar noise values. I'm surprised how quick this still is. Granted, you need to lower the resolution, but its barely noticable from afar.

Screen capture of the Blender viewport, where I play around with different parameters for an asteroid field that, when very close together, merges into a single irregular-shaped lump of grey rock. When stretched out, the asteroids have different sizes and shapes.

Evening doodle: a quick and dirty asteroid generator in #Blender.

Using cascaded noise displacement along the normal vectors, and a bit of shader magic sprinkled on top to make even low-res meshes look decent.

Blender screen capture of an asteroid generator. Different sliders control noise scale, displacement strength and the random noise position. Everything looks snappy and real-time while showing high-resolution details on the asteroid's surface.

Heute Abend solltet ihr nach Sonnenuntergang tief im Südwesten die schmale Mondsichel finden. Links über ihr steht Saturn und rechts unterhalb sollte der flinke Merkur zu sehen sein. Viel Glück.

It's a problem that we only have one Universe. It's very hard to do statistics with N=1.
