Data Sources & Attribution

AstroLAB is built almost entirely on open data published by public science agencies and open-source projects. This page lists every external source the site reads from, so you can go to the original if you want to check something or dig deeper.

Space Weather & The Sun

Solar and geomagnetic conditions — storm scales, solar wind, flare activity, and the aurora outlook — come from the NOAA Space Weather Prediction Center. Solar disk imagery and the activity time-lapse are served by Helioviewer, which draws on NASA and ESA observatories including SDO and SOHO. As works of the U.S. government, NOAA and NASA data are generally in the public domain.

Asteroids, Close Approaches & Fireballs

Near-Earth object close approaches, orbital elements, and fireball/bolide events come from NASA/JPL Solar System Dynamics and the Center for Near-Earth Object Studies (the SSD/CNEOS APIs).

Launches

Upcoming and recent launch schedules from Launch Library 2 by The Space Devs.

Space Headlines

Space news aggregated by the Spaceflight News API, which links back to the original publishers.

Astronomical Events & Calendar

Eclipses, meteor showers, and planetary events curated from NASA eclipse predictions, the International Meteor Organization, TimeAndDate.com, and In-The-Sky.org, whose event feed also supplies the annual calendar.

Sky Chart

The interactive sky chart is rendered with D3-Celestial, an open-source project by Olaf Frohn, together with its open star, constellation, and deep-sky catalogs. The library and its data are delivered by the jsDelivr CDN.

Observing Conditions & Place Lookup

Local weather and viewing conditions come from Open-Meteo, used under its free tier for non-commercial use, which also provides the place search and reverse lookup. Nearest-populated-place names for fireball events are derived from the GeoNames cities15000 dataset, used under CC BY 4.0.

Missions

Mission histories are compiled from public sources and link to official agency pages. Artemis II tracking uses official NASA mission resources, imagery, and feeds, including visualisations from the NASA Scientific Visualization Studio.

Catalogs & Reference

Messier and deep-sky catalog details draw on the SEDS Messier Database and Wikipedia, whose text is available under CC BY-SA. Impact, crater, and meteorite records are compiled from published scientific and reference sources, each linked from its entry.

Hosting

The site is hosted on Cloudflare Pages, with a small number of serverless Functions that proxy and cache several of the feeds above.

Licensing And Ownership

All third-party data, logos, and trademarks remain the property of their respective owners, and use is subject to each provider's terms and licensing rules. Original photography and written mission summaries on this site are the work of its operator.

Corrections
