Nuclides vs Satellite Tracker

Nuclides is a professional reference and calculation toolkit for nuclear technology, radiation protection, nuclear medicine, reactor data, and education. Key features: 1. Look up elements and nuclides, including half-life, decay modes, parent and daughter nuclides, radiation energies, and emission probabilities. 2. Explore extended nuclear data, including excited levels, gamma transitions, electron data, fission yields, nuclear moments, and ENSDF evaluation information. 3. Simulate gamma spectra from nuclide gamma-ray data with controls for live time, energy resolution, background, dead-time loss, and related detector parameters. 4. Run decay calculations, activity estimation, dose-rate estimation, effective dose estimation, radiation dose comparison, and unit conversions. 5. Use theranostics dosimetry tools for time-activity data, cumulated activity, and simplified MIRD relationships. 6. Consult radiation safety atlas entries, radiopharmaceutical references, material densities, physical constants, binding-energy charts, toxicity information, and the INES scale. 7. Browse nuclear power plant data, operating records, advanced reactor references, and small modular reactor information. Nuclides is designed for professionals, students, and users who need fast nuclear data lookup, radiation calculations, and clear technical references.

Every satellite in the sky, live on a spinning globe — all 14,000 of them. Satellite Tracker draws the whole catalog moving in real time: Starlink's woven shells, the GPS constellations, the ISS and Tiangong, spent rocket stages and tumbling debris. Filter by constellation or by nation, crank time to 600× and watch low orbits swirl while the geostationary ring hangs still. TONIGHT'S SKY See which satellites you can watch with your own eyes tonight — sunlit passes over your location, with rise direction, peak height and duration. Get an alert 10 minutes before, walk outside, look up. POINT YOUR PHONE AT IT AR mode draws satellites on your real sky. Pick the ISS, follow the arrow, and the station is right where your camera points. EVERY SATELLITE HAS A STORY Tap any dot for altitude, speed, period, inclination and its full orbit ring. Search 14,000 objects by name. Share any satellite with a friend. Works fully offline with a bundled catalog; live orbital elements when connected.
