How Astronomers Are Circling a Black Hole | Out There
How Astronomers Are Circling a Black Hole | Out There At the heart of our Milky Way, hidden by the dust clouds of Sagittarius lies a trapdoor to Eternity with supermassive black hole or at least astronomers. Nobody has ever seen a black hole directly, but astronomers can measure it by its pull on nearby stars. In the year 2002, a young blue star named best made a sharp turn. The star was moving so fast, but only the gravity of 4 million Sons condensed into a tiny space could have kept it on course. That object is Sagittarius A star, the dark Hub of our home Carousel of stars. If it’s not a black-hole astronomers, don’t know what else it could be every 16 years S2, it’s close to the black hole, accelerating to speeds of 3,000 miles a second. This year, astronomers were watching closely. Two teams track the star to see what it might betray about gravity: the dark monster in orbits to pass close to the black hole time, for it appeared to slow down reddening the Starlight in what astronomers called the gravitational redshift S2 survived its close encounter, but other Intruders to the galactic center have fared far worse than few years ago, and approaching gas cloud was heated, stretched and torn apart. Now, the clouds head is rushing away, while its tail is falling into the black holes bottomless gullit last spring. The very large telescope and chewy captured blurry glimpses of the star and have a cloud repeat that surrounds the black hole. The black hole itself is black, no light can escape from it, but the area around the whole can be hundreds of times brighter than the sun doomed. Swirling inward are heated to Billings of degrees. Spring Jets of radio energy into space astronomers recently detected a wobble in the disk, a hotspot that Circle the black hole every 45 minutes. That’S the closest. We come to probing the edge of a black hole. Anything orbiting closer would fall in and vanish in the coming months. The Event Horizon telescope a plan network of a telescopes May produced the first image of the black hole itself at certain radio frequencies. The accretion disk of hot gas becomes transparent, like hers, gravity, creating bright arcs around a dark silhouette. The shadow of the black hole, the tombstone for matter and space-time black holes, don’t only destroy the whole feeds on the material swirling around it. Turbulent magnetic fields can shoot jets of gas above and below astronomer studying other galaxies have found hot Bright Stars within the escaping Jets. Newborn stars born on the Run S2 will swing past the black hole again in 16 years to Once More Walk its tightrope along eternity by then Glimpse the silhouette of Doom at the center of our galaxy. Perhaps it will look as mathematically Immaculate is Einstein, dreams and century ago this fear of no return, but that’s just the outside the inside. We can only imagine mystery is opaque and unknowable as the future or time itself. Astronomers are probing the edge of Sagittarius A*, the supermassive black hole at the center of our galaxy.
