30229 Cant we determine the 3D position of any star for which we know the distance to?  Like for example, the Tycho catalogue. If you just know the distance and direction it is from Earth can you not plot its 3D position by placing the Earth at the center of a navigation grid?  You should be able t...

29301 Yes, I quite agree with you and like Carl Sagan once said, "Exceptional theories require exceptional evidence." Today this video was uploaded to youtube PLyEO0jNt6M In my opinion this is a very consistent way of analyzing the problem. The most clear "UFO evidence" is proba...

30037 galaxy distribution looks to even, lacks void size Expand on this please. Galactic stellar distribution seems right to me. Between spiral arms there are no voids just less density of massive stars. 30038 Would it be complicated to add all cataloged stars? What do you mean by all catalogued st...

Beautiful. That color contrast!

Watsisname did an excellent explanation in February of what would be like to accellerate with a ship at constant 1g . Now, the CoolWorlds Lab released a video just going through all the arguments :) b_TkFhj9mgk But before CoolWorlds Lab, even before Watsisname, there was this inspiring explanation ...

Qr Bbpost That's Jupiter you're thinking of, Saturn's axial tilt is much greater.

Again!? Haha sorry guys. That's true. I think I had read the value for the orbital inclination :S

29297 Just to correct you about S/2007 S 3, it is inclined 177.22° to the ecliptic, not Saturn's equator. The Wikipedia list on the moons of Saturn mentions that the listed inclination values of the retrograde satellites are to the ecliptic while the prograde values are to Saturn's equator. Good ca...

29294 The weird thing is they repeatedly talk about hypersonic flight and the objects coming to a sudden stop and turning on a dime.,  It was shocking to hear and see the Secy of Defense saying that the only two possibilities being extra terrestrial or another nation having developed more advanced ...

29293  Gulliver's Travels, the writer made predictions about the Martian moons that turned out to be relatively accurate! That's an awesome story. I heard that since the time of Galileo it was speculated that Mars had two moons, there was no observation to support the statement but rather a numerol...

29282 This has been all over the news around here https://www.nytimes.com/2019/05/26/us/politics/ufo-sightings-navy-pilots.html Experts were careful to note that there are many non-alien explanations for these unexplained sightings. Still, this isn’t the first major report on UFOs in recent years. ...

29290 I think Deimos does that? Both Phobos and Deimos are tidally locked to Mars. So probably no. If you are refering to the orbital motion it is also a no. Phobos and Deimos are both prograde (they orbit in the same direction of Mars's rotation). But an interesting thing happens: From the surface...

29245 When looking at a map of the universe, I see a bunch of strings throughout the image. What are they and why are they there? This is just the Laniakea supercluster of galaxies (Is the supercluster where the Milky Way is located and some 100.000 other galaxies). Important to note the difference...

29184 However, notice that it's "G!kunll'homdima," not "Gǃkúnǁʼhòmdímà." Just as I partially suspected, they slightly altered the weird characters What an awesome name. Sorry for the little off-topicness but if anyone was wondering the object's name apparently is pronunced like ...

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...

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...
