> Stellarium is a free open source planetarium for your computer. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope.

In case someone was wondering.

    It's pretty cool that they have a web client too

    I'm surprised at how much stuff there are above me if not for all the light polution

      I'm in the Southern Hemisphere and even in my nearest "large" city, you can still see the Milky Way on a clear night. Not in all its glory, mind, but you can see it, and Crux Australis, such a definitive Southern Hemisphere constellation that it appears on five national flags. Although it can be hard to see Epsilon Crucis in a city, as it's a bit dimmer than the four main stars.

      But then I travelled to far more densely populated Northern Hemisphere countries, and wow, I see what light pollution is, I really wanted to see Orion right side up, but wasn't able to get far enough away from populated areas when the sky was clear.

      Another benefit of living on a sparsely populated island I guess, not sure if it offsets all of the downsides (island "tax" is real, small economy makes it hard to challenge incumbents who dominate a market, we get very few concerts from the top bands, often left off maps), but it did make appreciate what we have in terms of the night sky.

      I'm a real big fan of dark sky reserves, it's a fantastic idea. [0]

        I'm from England, where we don't see many of the stars and when we were university students (over a decade ago now), my wife and I were in Switzerland, up a "hill" near Caux Palace; it was the first and only time I've seen the milky way and the only time I'd ever seen the night sky that way; without light pollution.

        I hope to do it again, somewhere, some day because it's an incredible experiencev to just lie on the grass in complete darkness like I've never known at home and let you eyes adjust to just show full the night sky is.

      I mean, it is the... entire visible universe. More than 100 billion stars in our galaxy. Maybe 200 billion galaxies in the visible universe. If you could see into infrared, you could see stuff 34 billion light years away:

      When I enter my correct location into the web interface, it thinks the sun has just set. It's actually the middle of the day here.

      I've tried slight variations of my current location in case it was just getting mixed up with other similarly named places elsewhere in the world. No luck.

      OTOH I already have the Android version on my phone and that has always worked just fine.


      • pbhjpbhj 2 months ago

        This seems like a reasonable choice though (same happens to me), they show you tonight's sky ... otherwise during the day they'd always show a star map with no stars.

        What would you want them to show during the day, on a star mapping website?

        • paledot 2 months ago

          At risk of sounding inane, the stars are still in the sky in the daytime. A star map showing what you would see during a solar eclipse is not an unreasonable choice either.

          • pbhjpbhj 2 months ago

            It's not stupid to show the stars over head right now, but the utility of showing stars as they appear next time you'll be able to see them seems clearly greater.

      • helb 2 months ago

        You can switch to current time (clock icon, then clock with arrow icon) and turn off the atmosphere (cloud icon) to see what's above you during daytime.

        The android app does the same for me, it shows a message with something like "it's daytime in X, fast forward time" and moves to the evening.

      • adastra22 2 months ago

        Maybe UTC vs. local time?

    • mceachen 2 months ago

      Wow, when did they add so many delightful high-resolution photos?

      Try zooming into the Moon, Mars, Saturn, or the Horsehead Nebula on a big monitor. It's gorgeous.

    • aptitude_moo 2 months ago

      The web version is a bit of a different project. Make sure to try the desktop version!

    • prox 2 months ago

      In the game Elite Dangerous, the galaxy contains 400 billion stars modeled by a Stellar Forge program. Since it’s launch about 7 years ago, less than 0.5% has been discovered, despite thousands of ships “in the black”.

      • Yoric 2 months ago

        They had the same problem with Elite Frontier, back in the days :)

        That was impressive for a game that fit on a single floppy disk. Well, there was a second floppy disk, but it only contained the midi version of the music, never quite understood what for.

    • chromatin 2 months ago

      Our forebearers had a totally different experience when viewing the night sky to be sure

    • daitangio 2 months ago

      On Polinesia island, in the night it is incredible! Give it a try if you can

Funny I should see this on the front page of HN the day before I finish my Stellarium port for Nintendo Switch [1]. Unfortunately a lot of the UI code in the 1.0 release made it harder to port so I'm currently basing the Switch version on the 0.xy tags, but it's still a great accomplishment for the Stellarium team!

1: Unless I get approval from Nintendo AND Noctua you will need an RCMed Switch with Atmosphere to run it.

  • Aissen 2 months ago

    Why wouldn't Noctua give their approval ? Why would they need to ? If they do, why would they be the only one who need to ? There does not seem to be a CLA for Stellarium.

    Now Nintendo has been very conservative with regards to what they accept, but it would be very interesting to try…

    Do you have a link to the nsp file?

Have been using it years for astrophotography planning.

I've never realized it was 0.x, as I haven't encountered a single bug with Stellarium in my lifetime either on desktop or on iOS.

Great to see it promoted to 1.0 (though I think its more of a symbolic thing)!

Lovely software, free and open source. Recommend to anyone who might want to explore astronomy.

  • cwillu 2 months ago

    Some projects use 0.x to indicate that there are features they want that they haven't written yet, as opposed to being an indication of stability.

As a telescope amateur, Stellarium is one of my favorite learning tools. Having used this happily for at least 15 years, I had no idea this amazing software wasn't at version 1 yet.

Abandoning 0ver after only 20 years. I guess it's never to late to drop down to 0.9.9

Nice to see projects like this reach their 1.0 milestone, even if the quality has already been there for quite a while.

Stellarium is such a great piece of software. Glad they are considering it stable now.

I’ve tried this with a low cost projector. I’m wondering if anyone experienced this with a better quality one?

  • Aachen 2 months ago

    I know of at least one planetarium that uses this software and the scripting interface for presentations. Nerdland festival had a dark tent with a projector that fills half a sphere this year with iirc a guide to star signs. Quality wasn't fantastic but for a sunny day and the limited budgets these places always have, it was quite acceptable.

I'm sure someone will explain how "not" can mean "is" in software policy-ease but it is still disappointing to read "Data Not Collected" (on the iOS store) when, in actual fact, data is collected, and shared.

  • bscphil 2 months ago

    For what it's worth, the app is a different (and closed source) project, even though there is significant developer overlap. I think if you reported this to them, they would probably be responsive, however.

    • IndySun 2 months ago

      Thank you. I have reported it to them, several weeks ago, and have yet to receive a response. I used the app and website contact emails and forms. Nothing.

At the moment from Eastern Time Zone, Mars, Aldebaran and Betelgeuse form a red right triangle in the eastern sky. I believe Mars will pass between Aldebaran and Pleiades in a week or so, forming a straight line with those two red stars as it passes, but I think the right triangle is more impressive. I haven't seen this announced in media. A month ago, Mars' transit close to Pleiades was announced, however.

  • lioeters 2 months ago

    I would love to receive a newsfeed of your astronomy observations, what to look for in the night sky.

    • Maursault 2 months ago

      Here[1] you go. I whipped this up last night for my brother and a friend. I just happened to be up late, only know about 4 constellations, and maybe half a dozen stars, saw Mars, distinctively bright red last night, and realized that two other red stars were nearby. Including Mars, there's only about 4 red stars that appear red that can be seen with the naked eye, the other being Antares (which at the time was well below the horizon). This will appear slightly different and the triangle slightly more oblique tonight as Mars continues (mostly due to Earth's changed position) along the ecliptic.


      • lioeters 2 months ago

        Ooh, thank you for the illustration. I was able to find the area on Stellarium Web. From where I am, it will be visible in the Eastern sky from around midnight, every night for a while as it gradually moves up. Cool! I'll keep an eye out. :)

Great news, thanks to all the maintainers!

I wish someone with the right expertise could modernize Celestia[1] like that.

A "1.0" release after more than 20 years... is remarkable.

Between Stellarium and Space Engine, you are in for a treat. Find an object in the sky with the former, and then visit it with the latter.
