Astronomers Detect Two Supermassive Black Holes in Binary Orbit
Two Cosmic Giants Locked in a Tight Dance In a landmark observation, astronomers have confirmed the presence of two supermassive black holes bound in a binary system, circling each other at the centers of a distant galaxy. The discovery provides a rare glimpse into the final stages of galactic mergers and offers crucial data for…

Astronomers Capture Two Supermassive Black Holes Dancing in Binary Orbit
Two Giants in a Gravitational Waltz In a landmark observation, astronomers have captured the rare sight of two supermassive black holes locked in a binary orbit around each other. These cosmic heavyweights, millions to billions of solar masses apiece, are situated at the heart of a distant galaxy and reveal crucial details about how galaxies…

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 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…

How the Lights Were Switched On at the Cosmic Dawn: Dwarf Galaxies as the Hidden Fireflies
The Spark That Shaped the Early Universe For decades, scientists have wondered what finally lifted the Universe out of its fog of neutral hydrogen during the cosmic dawn. A new wave of observations from the Hubble Space Telescope and the James Webb Space Telescope suggests the answer lies in the smallest galaxies imaginable: ultra-faint dwarf…

Stellar-mass black holes at galactic centers: new hints from distant galaxies
New hints about stellar-mass black holes at galactic centers For decades, astronomers have known that almost every galaxy hosts a supermassive black hole at its core. Now, a growing body of theoretical and observational work suggests there could also be a hidden population of stellar-mass black holes in some galactic centers, particularly in distant galaxies…
