What it does
Space-Time is a free, browser-based universe explorer and astronomy tool. No account, no ads, no install. You can fly from a planet's surface out to the edge of the observable universe, stand on the Moon or Mars and look up at the real sky for any date, watch real eclipses, and plan tonight's stargazing from your own backyard. It started as a passion project, basically the astronomy tool I wish I'd had in school. I'd love to hear what's confusing, what's missing, and what you'd build next.
Explore the solar system, stars, deep-sky surveys and the observed cosmic web in one continuous 3D universe. Free in your browser, with no account required.
Travel from the solar system to nearby stars, deep-sky objects and the observed cosmic web. Space Time brings astronomical catalogs, telescope surveys and computed motion into one navigable view. Distance determines which objects become visible. The same controls, selection and time system remain available from planets to large-scale structure. Planets give way to nearby stars, the Milky Way, galaxy clusters and the observed cosmic web as the camera moves outward. Swap the constellation figures, names and stories to Boorong, Inca, Māori, Hawaiian, Chinese and more. Dark-cloud figures like the Emu are drawn in the Milky Way dust, and every culture shows its authors, source and license. The…from space.pointdynamics.com

I really like Stellarium and SkySafari but I felt like these are primarily geared towards exploring the sky but not so much "here are the long list of things I want to see, when can I see them tonight and where". There's also not really a great option I've found that combines sky object planning + location weather details while still being free so I built this. The UI's heavily inspired by NINAs sky atlas + Robinhood. Right now you can: View the altitude chart of objects and 3D view Create lists of objects of interest View the annual max/min daily altitude of an object to find the best…

Galaxium, an experimental WebGPU space explorerAug 2026 · galaxium.app · ▲137Hello, I am the creator and maintainer of Stellarium Mobile. I have been working in my free time for about a year on this new project Galaxium, that is more about traveling in the universe rather than looking at the sky from Earth. It is still experimental, and at the moment I am not sure what it will become. Feedback is welcome.

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
