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" ...

Work progress 0.990

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...

Gaia DR2 White Dwarfs (NEW ADDON)

23397 I hope the catalog will be included in SE 0.990. Regarding this I talked previously with Vladimir and he think it is better to have this as an addon for the moment until we can integrate a significant amount of Gaia data in Space Engine. Why? Because in this way we avoid having unrealistic pr...

Gaia DR2 White Dwarfs (NEW ADDON)

Gaia's White Dwarf catalog Size: 73.221 White Dwarfs It has been a while since I said I would start working on Gaia's DR2 implementation in Space Engine (and I haven't show anything until now). A lot of decissions are been made and we are still probing how well behaved is the astrometry and the...

The Future of Humanity & Intelligent life in the universe

That's very interesting An'shur . I'm very skeptical with FTL travel been possible at all but expansion rates are an interesting topic in relation to all the speculative field of the Fermi paradox. I'm also very skeptical of extraterrestrial intelligence at all. I like the fact you thought about...
