  • Planet Mars! part 13: Artifacts of Ancient Astronauts (Please discuss each item!)
    First, we go to the World-Wide Telscope http://worldwidetelescope.org/webclient/. Source: 11 months ago
  • How long would it take the JWST to map the entire sky with the detail of the first Deep Field image? Would it even be possible?
    Cool as it is, that link unfortunately only shows the initial release images; however, the full web-client has a JWST folder that is being updated with new stuff. Source: over 1 year ago
  • Signs of life? Recently Discovered Fast Radio Burst 190520B is now the 2nd of around 500 known FRBs to have a so-called PRS counterpart showing consistent activity.

  • Ok I’m biased because the Andromeda galaxy is the best galaxy, but this is my new favorite bookmark!
    Just posted! From a friend who works on a project called WorldWide Telescope, they just had a big launch update yesterday so made some bookmarks to promote it. :). Source: about 2 years ago

  • My 9 year old nephews drawing of stars
    I think Celestia could be a good one. I also thought about SpaceEngine, but AFAIK it was kind of terrible at generating realistic planetary systems, among other things (pricey, huge, etc.). Source: about 1 year ago
  • What are the best resources to explore space from my computer?
    Celestia was something I played with before. Pretty interesting. Source: over 1 year ago
  • Lunar Occultation of Mars
    Celestia looks as though it would do it. Source: over 1 year ago
  • Tips to visualize Apollo 17 trajectory
    I'm looking for data and software to visualize the Apollo 17 trajectory (especially the "powered descent", lunar rendezvous and entry). I'm thinking of using celestia. I'm look for a data tables as well (time stamp, position for each part of the stack). Any tips are appreciated. Source: over 1 year ago
  • Help rediscovering a certain night sky exploration program?
    Yes, that's Celestia most likely. I'm not sure it is still maintained though. Source: over 1 year ago
