Two freshly created pages for my new rubric Space, one of which lists the most interesting launch vehicles, the other deals with current positions of unmanned spacecrafts, landers and rovers.

During the pandemic, I bought a 6-inch telescope and have hardly done anything with it so far. Two of the few videos, recorded with a Raspberry Pi HQ-Cam, are halfway presentable. Maybe that will put me in the mood for more.

My Moon animations wanted to be improved further, so I added two missing things: The libration - the wobble of the Moon - and the earthshine - the sunlight reflected from Earth. The former is already working quite well, the latter could be further strengthened.

In October 2024, Comet Tsuchinshan-ATLAS C/2023 A3 could be seen over Cologne, shortly after sunset. Wolfgang Tubis photographed it at three days from the right bank of the Rhine River.

I haven't had much contact with artificial intelligence so far, but I try it again from time to time. Usualy the conversations get a bit out of hand, because in a way AI has a character that's a bit exhausting.

A short and unfinished video that was made during the search for a Povray rocket launch site. I have no idea if the macro collection behind it will ever be finished, but I still wanted to present the first test flight in advance as a teaser.

Till now I have deposited pictures and videos of planets rendered with Povray in the rubric astronomy, but it is slowly getting crowded there. So I moved them to a new one and added old star field animations.

I created a lite version of the current HYG star catalogue with 120,000 entries. It contains fewer columns, reduced accuracies and is half the size of the original. The result can be downloaded as a SQL import and in the form of Povray arrays.
