  • SkyMap
    This is very cool, and looks like it targets you wanting to look stuff up and I will probably use it at some point. But I feel that anyone looking at this and thinking "oh that's cool" should also try installing Stellarium ( It lets you see what you can see in the night sky from any location/time on Earth, and is really useful for helping you identify what you're seeing in the night sky. I... - Source: Hacker News / 9 days ago

  • Not sure what this would be. Ive seen it for years and thought it was just a weirdly rectangular cluster of stars. What do you guys think?
    They're the Plieades. For future reference you can check on what's in the sky with software like Stellarium. Source: 9 months ago
  • ‘Limited' UFO disclosure believed to be used soon as a strategy of deception as end times Bible prophecy being fulfilled indicates. The truth about the future and how to be prepared.
    We have been experiencing distress and perplexity of nations upon the earth unlike anything in modern history. There have been record hurricanes, cyclones, typhoons, and flooding globally which appears to relate to “the sea and the waves roaring” and according to research using the Stellarium Astronomy Software, this was a one time alignment on September 23, 2017 involving the sun, moon, and stars that accurately...

  • When it comes to software what do you use and can you go a little bit into detail on how to use it

  • Floating Feature: A Sky Built Before Us - The History Of The Stars
    I did a bit of poking around using Stellarium and found two stars that I thought were admirable candidates, and I wasn't sure why Nell and Ruggles didn't think so: Phecta and Megrez, Gamma and Delta Ursae Majoris. These are the two stars that make the left side of the 'scoop' of the big dipper. According to Stellarium they were at their closest to being in a north-south alignment in the year -2586, that is 2587... Source: 12 months ago
  • I'd like to share my personal web project. Those who are into astronomy might wanna see this.
    But if you need an API I think has an one. Source: 12 months ago
  • Portable, cross-platform, reliable 3D library?
    If I wanted to build an app like Stellarium, displaying a 3D model, but not requiring fast animation, not a game, more visualization, what libraries should I be considering for the display/UI portion of this program? Source: 12 months ago
  • New scientific discoveries confirm the legitimacy of basic astrology. (The position of planets around the sun having an overall effect on the earth and the life on it).
    Once a formal relationship is proposed, like Depression = Birth Sign / Current Sign, or Lunacy = Moon Phase \ Distance to Saturn,* or probably something much more complex, more math can be used to draw up simple tables (or software) for laymen that predict more (or fewer) people are going to be depressed/go crazy when Saturn and the Moon line up just so. Then, we can compare the level of actual depression/lunacy... Source: 12 months ago
  • Date ideas when you live in a small village?
    Or just sit out and see the stars and galaxy's, no special equipment needed just 15-20 min darkness for your eyes to adjust (maybe a phone app like Stellarium phone app which will sync up so the phone will tell you what it is pointing at). Source: about 1 year ago
  • i have no clue what this is, if someone could help me that'd be great
    I'd guess Venus, but the best way to be sure is with software like Stellarium. Source: about 1 year ago
  • Help identifying flashing stationary object at night.
    You could download Stellarium. It's free. There's a satellite feature in there which allows you to see which satellites are above you. As to different intensities of the flashing, this is typical, as the angle of reflection of the sunlight from the satellite isn't always the same. And these aren't disco satellites, although there are a couple in orbit with reflective panels completely surrounding them. These are... Source: about 1 year ago
  • UK 11:30pm, can anyone quickly tell me what the object to the bottom right of the moon is, I don’t know where else to ask…..
    Plugging things into Stellarium, it's probably Venus. Source: about 1 year ago
  • Which star/planet would this be?
    I checked it using the free software package/website Stellarium. Source: about 1 year ago
  • Is this a star? It almost seems to change sizes also.
    Without a time, location, and direction, it's impossible to tell. In general, something like Stellarium will make it clear what the bright objects that are up near you are. Source: about 1 year ago
  • Northern Europe-based astrophotographers, what is good to photograph at this time of the year?
    Install stellarium and that'll give you a good idea of what's hanging out up there. Press F10 and go to the WUT (whats up tonight) tab. Play around with the controls at the bottom and left of the screen, you can also input your current time or just fast forward etc to when you plan to shoot. Ideally you should aim to shoot high above the horizon and away from city/urban lights etc. A light pollution filter can... Source: about 1 year ago
  • If we saw life on Pluto using some high powered telescopes on earth. How long "in the past" would we be seeing in real time?
    Pluto is, depending on where it is in its orbit ~30-50 au from earth, so the speed of light time is ~4-7 hours. (Stellarium says that it's currently ~4 hours, 47 minutes). This is of course, ignoring that we're not going to find life on the surface and that there was a spacecraft flyby of it in 2015. Which leads me to the question: were you thinking of an exoplanet? Source: about 1 year ago
  • why no stars?
    Download the free Stellarium app and look at it while on the ship. It will show you what you would be able to see if the ship’s lights didn’t overpower the stars. Source: about 1 year ago
  • First telescope purchase
    5) Once you have a list of things you want to observe, you may find a planetarium program like Stellarium quite useful. It will simulate the night sky and allow you to see where to point the telescope to observe specific objects. Source: about 1 year ago
