The 20 pages that link to Sagittarius A*, each with the reason it gives.

• Milky WayBroader topic: Its stellar orbits provide direct evidence for a roughly four-million-solar-mass black hole in the Galactic center.

• Black holeBroader topic: Stellar orbits around it provide direct evidence for a massive central object.

• Supermassive black holeBroader topic: Stellar orbits around it provide direct evidence for a supermassive black hole in our own galaxy.

• Event Horizon TelescopeBroader topic: The EHT produced the first image of its black-hole shadow in 2022.

• Chandra X-ray ObservatoryBroader topic: Chandra observations track X-ray flares and hot gas near the black hole.

• Galactic CenterBroader topic: It is the Galactic Center’s dominant compact object and anchors the surrounding stellar orbits.

• Very Long Baseline ArrayBroader topic: VLBA observations help measure its radio structure and the motions of nearby sources.

• Solar massBroader topic: Its mass illustrates how the same unit scales from stars to galactic centers.

• W. M. Keck ObservatoryBroader topic: Keck’s long-term measurements of nearby stars helped establish its mass and location.

• Galactic astronomyBroader topic: Its mass and activity inform studies of the central Galaxy, though its growth history remains unresolved.

• Andrea M. GhezBroader topic: Stars tracked by Ghez orbit this source, whose mass and compactness identify it as a black hole.

• Astronomical black holesBroader topic: Stellar orbits around it provide strong evidence for a central black hole in our galaxy.

• Black hole astronomyBroader topic: Its stars and radio emission provide unusually close evidence of a galactic-center black hole.
