  The supermassive black hole at the center of our galaxy may not be sleeping, after all. Previously, scientists believed that the supermassive black hole at the center of the Milky Way was a sleeping giant. It would periodically awaken to devour any star of gas clouds that fell into it. It would then release radiation and particles into space in a long plume or jet of energy. The supermassive black hole at the center of our galaxy is leaking Artistic rendering of a black hole in space. Image source: Vadimsadovski/Adobe Scientists believe that the biggest outburst from the black hole came around two million years ago. However, new evidence has been found that the outburst could still be active. The  Hubble telescope  has discovered circumstantial evidence that the black hole is still smoldering after the outburst two million years ago. Astronomers are currently investigating the data that Hubble has found. That data includes a photograph of a bright knot of gas that Hubbl...

O ur Milky Way galaxy has a supermassive black hole at its center, known as Sagittarius A*, which is 4 million times the mass of our sun. And that black hole has a leak.  © NASA, ESA, and Gerald Cecil (UNC-Chapel Hill); Image Processing: Joseph DePasquale (STScI) A composite of view of X-rays and warm ionized gas near the galactic center. Astrophysicists have detected a “vestigial nuclear jet,” a blowtorch-like outburst of material, that burps out of the black hole whenever large masses of stars or gas clouds fall into it. These jets are remnants from a larger outburst that occurred several thousand years ago. NASA’s Hubble Space Telescope has not yet been able to directly photograph the phantom jet, but astronomers have pieced together evidence that it exists and regularly sputters. The findings were published in  The Astrophysical Journal .  In 2013, astronomers detected X-rays with the Chandra X-ray Observatory and radio waves with the Jansky Very Large Array tele...
