GoKawiilOpen-source astroterm brings an ASCII star map to the terminal
Astroterm is a C-based command-line program that renders real-time positions of stars, planets, constellations and moon phases as ASCII art, with views configurable by date, time and location. It is available via package managers including pacman, dnf, Homebrew and Nix, or can be built from source.
GoKawiil's interpretation of the reporting above, not reported fact.
The project offers a lightweight, no-GUI way for developers and hobbyists to visualize the night sky directly from a terminal, which could appeal to users on low-resource systems or those who prefer command-line tools. Its availability across multiple package managers suggests the maintainers are aiming for broad accessibility among Linux and macOS users.
- Astroterm renders real-time star, planet and constellation positions in ASCII within a terminal.
- Users can customize views by date, time, and location, including past or future sky states.
- It's installable via pacman, dnf, Homebrew, Nix, or built from source, and open to community contributions.
Celestron NexStar 130SLT Telescope — If mapping the night sky in your terminal with astroterm gets you excited about astronomy, why not take it further with an actual telescope? The NexStar 130SLT lets you locate and track the same stars, planets, and constellations astroterm renders in ASCII, but in real, observable detail. It's a great way to bridge the gap between command-line stargazing and genuine night-sky exploration.
