Unveiling the Mysteries of Sagittarius A*: Recent Discoveries and Speculations

Science Space Exploration

Sagittarius A* is the enigmatic black hole at the center of the Milky Way, and recent discoveries have shed light on its behavior and the mysterious objects orbiting it. From unusual radio emissions to periodic patterns in radio and gamma waves, scientists are unraveling the secrets of this cosmic giant.

Unusual Radio Emissions

⚫️The black hole in the center of the Milky Way, known as Sagittarius A*, was officially discovered in 1974.

🔭Observing the orbits of stars in the region confirmed the existence of the black hole and its mass.

🌌Recent discoveries suggest the presence of something extreme orbiting very close to the central black hole.

🔍Black holes can only be observed in certain frequencies such as x-rays, gamma rays, and radio waves.

📡Strange radio filaments connected to Sagittarius A* have been discovered extending across the central region of the Milky Way.

Mysterious Objects and Periodic Patterns

🔍Observations of radio waves revealed periodic emissions every 76 minutes, half the frequency of previous emissions.

🔄The proposed explanation suggests an object in orbit around the black hole is causing these emissions as it passes through a certain point in the accretion disc.

🔬Further analysis using the firit telescope and gamma data confirmed the presence of the same periodic pattern.

💡The object is likely held together by a magnetic field and emits periodic emissions in radio light.

❓The nature of the object remains a mystery, and it could potentially be something entirely different, like a magnetic tire.
