Is Celestia good?

• Show HN: The Atlas of Space

  Incredible work! My son really had a blast scrolling around and exploring last night. Did you take any inspiration from Celestia (https://celestiaproject.space)? It's been over 15 years since I last really used it (and starts with defaults not geared towards visualizing just our local solar system) but seems to have a lot of the features others have suggested. Might be useful to poke around and see how they solved... - Source: Hacker News / 9 months ago

• The Planets Today

  An honorable mention: https://celestiaproject.space This but in 3D and adjustable for any date. - Source: Hacker News / about 1 year ago

• ESASky

  Pretty much everything beyond our solar system is essentially fixed on a human timescale. Over 2000 years, a typical star will move about half a degree. That's the width of the moon in the sky. There are of course notable exceptions like Barnard's Star, whose movement is pretty obvious on photographs taken over several decades. If you want to explore how space changes over time, I recommend you look into... - Source: Hacker News / over 1 year 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: over 2 years ago

• What are the best resources to explore space from my computer?

  Celestia was something I played with before. Pretty interesting. Source: over 2 years ago

• Lunar Occultation of Mars

  Celestia looks as though it would do it. Source: almost 3 years 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: almost 3 years 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: almost 3 years ago

• Honestly can't tell you guys what this is, just know i was high asf and saw this during a late night smoke sesh. Thoughts? Salem OR.

  I hope this information has been useful to you, and enlightening. See the free PC programs Stellarium and Celestia if you'd like to learn more about the movement of the Earth and planets, as well as other objects in the night sky. Source: almost 3 years ago

• Stellarium 1.0

  Great news, thanks to all the maintainers! I wish someone with the right expertise could modernize Celestia[1] like that. [1] https://celestia.space. - Source: Hacker News / almost 3 years ago

• A very simple observation that destroys the ridiculous dome proposal. It's not flat guys, trust us on this one.

  If you wish to demonstrate this to yourself, grab Celestia, a free celestial exploration program that you can easily use to show the lack of change in star positions across seasons, but then move a substantial distance away in order to show the motion of stars over large distances. Here's an example. Source: about 3 years ago

• What do you suggest for A realistic sky map to observe stars, planets, satellites and constellations?

  What? You mean like Celestia or Sky Map? That's not really cosmology you know. Source: about 3 years ago

• There are many constellations visible from Earth. Has anyone worked out what would be visible from a planet that's very distant to us?

  I haven't used it, but the free program Celestia is supposed to be able to do this. Source: about 3 years ago

• Is there a program to show what the stars could look like in, for example, 3000 years?

  I think you can do this with either Celestia or Stellarium but they've been updated since I used them years ago. I know you go forward and backwards in time, but not sure 3,000 years is possible, but maybe. Here's another list of possibilities I found though. I think screen captures are possible with the first two. Source: about 3 years ago

• Genuine question: How is it that the Milky Way is in the constellation Sagittarius? I thought that was a constellation within the galaxy and I haven’t been able to find a clear answer online. I love learning about space but it’s super confusing!

  There are multiple. I like using SkySafari. Celestia is FOSS software that will also do this. Source: over 3 years ago

• 100,000 Stars - An interactive 3D visualization of the stellar neighborhood, including over 100000 nearby stars.

  If you like this, definitely check out Celestia, it's amazing. The download/install is super quick and you have a full program containing all known stars (I think). To feel proper awe, make sure to crank up "visible stars" with ] and then start zooming out. Source: over 3 years ago

• can you help please??

  If I may suggest Stellarium: https://stellarium.org/ A dark room with a projector would be nice, but a computer monitor also works. It's also good for letting you have an idea of what you can see & when. You can also try https://celestia.space/. Source: over 3 years ago

• Show HN: I made a site where you can travel in space in the browser

  Very neat! This is similar in concept to the Celestia: https://celestia.space/ Celestia has been around for years so the spaceinbrowser site can't really compare in terms of features. But being able to run in a browser rather than having to download and install a desktop application makes it so much more accessible. The effort put into performance optimization shows. I'd love to see more planets added. - Source: Hacker News / over 3 years ago

• Looking for the largest map of the Galaxy

  If you want a 3D representation of the Galaxy with procedurally generated stars, you'd be better off just downloading the Space Engine or Celestia. Source: over 3 years ago

• First time observing the moon side by side with my daughter (20 moons old)

  You could also just talk about the topic. Explain, in an age-appropriate manner, what stars, planets and moons are, how they behave in space, what they are like, show pictures and videos of them, use a program like Celestia or SpaceEngine to explore the galaxy a little, play some Kerbal Space Program with him, perhaps have him run around you like a moon would orbit a planet.

• Close to real time Earth satellite video in color from public data

  Celestia: https://celestia.space/ Stellarium's cool too, but it's more focused on what you see if you look up at the sky. Celestia's more of a broad "fly around the known universe"-type of simulator. - Source: Hacker News / over 3 years ago
