Significant Content Expansion: Multi-Agency Integration This update represents a major architectural enhancement, expanding from a single data source (NASA) to four authoritative astronomical image archives: 1. NASA Open API (existing) 2. ESA/Hubble Space Telescope Archive (integrated) 3. ESA/Webb Space Telescope Archive (integrated) 4. ESO Public Image Archive (integrated) This expansion provides users with: - Significantly larger image collection (5x+ increase) - Diverse observational perspectives (optical, infrared, ground-based) - Comprehensive coverage of astronomical phenomena The multi-source architecture required extensive testing to ensure seamless integration and consistent user experience across all data sources.
