Interactive sky map with multiwavelength overlays: This image shows an interactive sky map with multiwavelength layers, including a Fermi color layer (highlighted in red). The map allows users to overlay multiple wavelength bands and visualize celestial sources, with an elliptical red frame marking a source that can be clicked for detailed information (such as basic data, historical alerts, and related papers from ADS). In the upper left corner, users can select different coordinate systems; the lower left corner displays the visible sky regions of different telescopes; and the upper right corner offers different projection modes.
