General suggestions for SpaceEngine

28951 different vision or filter like thermal,luminosity,big or small... What exactly do you mean by "luminosity" vision and "big/small" vision? You can currently control many settings related to magnitude of the objects and brightness sensitivity of the camera. You can go anywh...

History of SpaceEngine

28765 I'm curious, how much time it took to render that video, and on what kind of hardware. And, maybe more interesting, what software was used, and how long it took to create it and setup the scene. The info I was able to gather says that this was rendered by a raytracing algorithm in FORTRAN usi...

History of SpaceEngine



This is the first CGI rendering of a complex landscape (with 3D clouds, islands and water). It was done in 1981. I saw it today and it reminded me of SE. In some sense this is the beginning of it all.

28609 I explained that we could, for example, see the true colors of nebulae such as the Orion Nebula, which we can see in shades of grey from Earth. This would make people aware that telescope photographs are not necessarily in the visible light domain. And I would have liked to have your personal...

General suggestions for SpaceEngine

28575 My idea is to be able to spawn in 3D models, including stuff like Sol's heliosphere, the M87 black hole, IC 1101, etc. near something like the Solar System and be able to use a simple GUI to move the objects around, set transparency and rotate. It'd be awesome to be able to place the m87 blac...

The Future of Humanity & Intelligent life in the universe

This is a very interesting video, let me calculate some minor facts. The video starts with a 1 year/sec speed, which means that the video could have started 125 seconds before that (~2 minutes before) with real time flow (1 sec/sec speed), if we hold the "doubling of speed each 5 seconds" ...

17483 Great model, thanks! scr01150.jpg As with Mattias Malmer's Churyumov-Gerasimenko 3D model we now have a model (by NASA) for Asteroid Bennu with a resolution down to 75 cm. There are no textures for now and the model will probably improve in the near future but I thought I had to mention it if...

Luminosity of supergiant stars

I probably don't get the actual issue you are seeing here but for me this is completely normal. Absolute magnitude of a star is the apparent magnitude as seen at 32,6 light years from that star (10 parsec). In all your examples the stars are way closer to the observer so many of absolute magnitude -...

Astrophotography

Fun fact: The "Popping in of HD textures" bug in Space Engine has happened a lot of times in many versions (for Intel users is very common). https://cdn.discordapp.com/attachments/499019456874414100/499057827214655499/scr00547.jpg While reading this , I just remembered that the first time...

Cosmology Discussion Thread

This is so exciting! I have little background in the topic and a huge amount of questions (from the silly to the philosophical). Going to take notes of each one of your amazing explanations. Thanks for the effort of making this (and an entire cosmological simulator) just for us. I'm going to learn a...

Gaia DR2 White Dwarfs (NEW ADDON)

23516 "sdB" is a valid spectral class in SE. It is equivalent of "B VI". Ups, you are totally right. It wouldn't make sense if SE didn't have that sorry. And yes spectral classification is quite "an art" at some point. There are a lot of schemes when you go in detail a...

Gaia DR2 White Dwarfs (NEW ADDON)

For the 120 White Dwarf binaries I ask for a community addon here. You can take the data from the attached file. The spectral classes are similar to those used in SE but there might be some differences. For example, a DAB2.4+M is a binary with a DAB White Dwarf (SE allows for the specific kind of DA...

Gaia DR2 White Dwarfs (NEW ADDON)

23504 But this is solitary white dwarfs? WD in binary systems, which was not resolved by GAIA, still lurking there. Exactly! Yes, I should have noted that. If there is a high \Delta m in a binary (like the case of Sirius), the high contrast would still hide the White Dwarf. We have reached complete...
