Sagittarius A* Reveals Violent Past of Milky Way’s Black Hole
Introduction: A Black Hole With a Hidden History The supermassive black hole at the heart of our galaxy, known as Sagittarius A* (Sgr A*), has long been thought of as a quiet giant. Recent findings from an international X-ray spacecraft challenge that quiet image, suggesting Sgr A* was far more violent billions of years ago.…

NASA X-ray Eyes Reveal Violent Past of the Milky Way’s Supermassive Black Hole
Introduction: A Quiet Giant Thankful for X-ray Clues For years, the supermassive black hole at the heart of our galaxy—Sagittarius A*—was thought to be a dormant giant, calmly consuming the occasional star or gas cloud with little fanfare. A recent international mission, using state-of-the-art X-ray observations, has turned that assumption on its head. The data…

How X-ray Discovery Rewrites the Milky Way’s Black Hole History
The Sleeping Giant Awakens in X-ray Light For years, scientists have described the Milky Way’s central supermassive black hole, Sagittarius A*, as a quiet giant—largely dormant and unremarkable in its activity. Recent data from an international fleet of X-ray observatories tells a dramatic different story. By tracing powerful X-ray echoes and high-energy outbursts, researchers have…

Scientists detect possible wind from the Milky Way’s supermassive black hole
Introduction: A new clue from the heart of the Milky Way For years, the supermassive black hole at the center of our Milky Way—known as Sagittarius A* (Sgr A*)—has reminded us that galaxies are not calm, static islands in space. While it is relatively quiet compared with the blazing beasts that light up quasars elsewhere,…

Wind Blows from the Milky Way’s Black Hole: Evidence Emerges
What the discovery suggests For decades, scientists have watched supermassive black holes at the centers of galaxies both consume material and, on occasion, spew it back into space as powerful outflows. While some active galaxies proudly display dramatic jets, our Milky Way’s own Sagittarius A* has long appeared unusually quiet. The latest observations, however, hint…

Wind from Sagittarius A*: Evidence of a Galactic Black Hole
Scientists spot a ‘wind’ blowing from the Milky Way’s center For years, astronomers have watched the Milky Way’s core with a mix of curiosity and caution. At the center lies Sagittarius A*, the supermassive black hole that anchors our galaxy. While many black holes are famous for the spectacular jets they spew into space, Sagittarius…
