About AstraPixels
AstraPixels is a captivating animated, pixel-art map of the solar system that displays every celestial body at its real, current position. Rather than relying on copied lists, positions are dynamically computed directly from published orbital elements. Users can seamlessly zoom in and out from the blazing Sun all the way out to the distant Kuiper belt, exploring a rich catalog of 171 catalogued objects complete with sourced facts.
In addition to educational exploration and tracking what the night sky will do over the next six months, AstraPixels introduces a unique ownership feature. Every rock in the system is available for purchase: users can claim an asteroid for just $5, keep it forever, and assign it a custom name of their choice. Please note that names assigned here appear exclusively on AstraPixels and do not serve as official IAU designations.
Pros of AstraPixels
- Accurately positioned celestial bodies computed from published orbital elements
- Charming, nostalgic pixel-art aesthetic with smooth zooming from the Sun to the Kuiper belt
- Comprehensive database of 171 catalogued objects featuring sourced facts
- Interactive sky tracking showing celestial movements for the next six months
- Fun, affordable asteroid naming feature allowing users to claim a rock for $5
Cons of AstraPixels
- Custom asteroid names are exclusive to AstraPixels and do not constitute official IAU designations
- Limited to 171 catalogued objects mentioned in the current database scope
- Web-based application reliant on an internet connection
Frequently Asked Questions
What is AstraPixels?
AstraPixels is an animated, pixel-art map of the solar system where every celestial body is displayed at its real current position, computed directly from published orbital elements.
How are the positions of the celestial bodies calculated?
The positions are computed directly from published orbital elements rather than simply being copied from a static list.
Can I buy an asteroid on AstraPixels?
Yes! Every rock in the system is for sale. You can claim an asteroid for $5, keep it forever, and name it whatever you like.
Are names given on AstraPixels official designations?
No. A name given on AstraPixels is shown exclusively on the platform and is not an official International Astronomical Union (IAU) designation.
About framejs
framejs is an open-source tool designed to build and share interactive web applications that exist entirely within a URL. Unlike traditional platforms such as Streamlit or Observable that require active backend servers to host code and maintain state, framejs encodes your app's entire architecture—including JavaScript, CSS, and application state—directly into the URL itself.
With framejs, there is no need for server hosting infrastructure, deployment pipelines, or complex build setups. Users can prompt AI to construct an application or data visualization, copy the generated link, and distribute it anywhere. The application runs natively in the browser, providing a light, serverless way to create and present interactive web tools instantly.
Pros of framejs
- Encodes JavaScript, CSS, and application state directly into the URL
- Requires zero server hosting, deployment pipelines, or build setups
- Open-source software that can be used standalone or embedded into existing apps
- Works seamlessly with AI prompting for fast app creation and sharing
Cons of framejs
- Does not support server-side backend logic or persistent backend databases
- Execution is strictly limited to client-side browser capabilities
Frequently Asked Questions
How does framejs work?
framejs encodes the full application codebase—including JavaScript, CSS, and state—directly into the URL string. When opened, the application executes entirely within the user's web browser without connecting to a dedicated backend server.
How does framejs differ from Observable or Streamlit?
Observable and Streamlit rely on backend servers that must remain online to run interactive code. framejs completely removes the server requirement by storing the code and state inside the URL payload.
Is framejs open source?
Yes, framejs is open source. You can use it as a standalone tool or incorporate it directly into your own software projects.
Do I need to host or deploy my framejs apps?
No. framejs requires no deployment, hosting, or build process. You simply share the generated URL, and the interactive app runs wherever the link is opened.
