Discover interactive visualizations, up-to-date research summaries, and learning resources about our galaxy's supermassive black hole.
Sagittarius A* (Sgr A*) is the compact radio source at the center of the Milky Way associated with a supermassive black hole. We break down the observations, history, and significance of this object in accessible language for all audiences.
Launch interactive models and timeline tours that let you visualize orbits, gravitational effects, and multiwavelength observations.
Use the controls to toggle star orbits, view the accretion flow, and simulate how observations change across different wavelengths.
Curated summaries of peer-reviewed papers, mission results, and accessible explainers written for non-specialists.
Summaries of recent VLBI, infrared, and X-ray campaigns with implications for black hole physics.
